Patent Application
20110113322
Markup languages, such as HTML, are currently the primary manner by which information is exchanged over the worldwide web (“the web”) of the Internet, or over related networks such as intranets and extranets. Markup languages in general provide a relatively rich assortment of functionality. Two example types of functionality that are relevant to one or more embodiments include: rendering behaviors, and layout behaviors. A behavior generally refers to an action, or processing, that can be performed in relation to a markup language element. An element in a markup language is a discrete entity that can be the combination of a set of markup language tags, any content contained between the tags, and any attributes the tags may have. Rendering behaviors generally are behaviors that specify how markup language elements are to be rendered, or drawn, on a medium, such as a display screen or on a printed page. Layout behaviors generally are behaviors that specify how markup language elements are to be laid out, or positioned and sized, on the medium.
Core engines that process markup languages, such as those found in web browsing computer programs and components of operating systems, do provide a rich assortment of behaviors for content authors. However, invariably the content authors may want to provide layout and rendering functionality that are not supported by the core engines. For example, the authors may want to position and size markup language elements in a way that is not supported by the core engine, or may want to draw the elements in a way that is not supported by the core engine. The prior art, however, only provides limited support for extensible behaviors. That is, the prior art only provides limited support for extended layout and rendering behaviors that are not supported by the core engine itself.
One way that extended behaviors are supported in the prior art is by using a technology known as a plug-in. Plug-ins are computer programs that can be called by the core engine to completely take over all the behaviors of an element associated with a plug-in, and that are referenced in HTML code. Plug-ins, while useful, have a significant disadvantage in that they take over processing of the element from the core engine on a wholesale basis. The core engine views a plug-in as a black box meant to process a given element or elements. The core engine does not participate in the processing of elements that are processed by the plug-in. Likewise, the plug-in cannot delegate some of the processing to the core engine. The plug-in represents an all-or-nothing affair: either the plug-in takes complete control of processing an element, without support from the core engine, or it does not. As such, the plug-in does not represent a complete solution to content authors' desire to extend behaviors supported by the core engine.
Another limited solution to provide extended behaviors in the prior art is by using dynamic HTML (DHTML) behaviors, which some prior art web browsing computer programs and operating system components support. DHTML behaviors are written similar to scripts, except that the DHTML behaviors can be separated from the HTML content itself. That is, while a script is integrated within the HTML content, a DHTML behavior is referenced within the HTML content. The DHTML behavior itself is still written as a script, but it is a script that is separate from the HTML content that references the behavior. Alternatively, the DHTML behaviors can be written in C++, a common computer programming language. DHTML behaviors are limited in the extensible behaviors that they can support. DHTML behaviors allow multiple HTML elements to be fused together as a single entity, and allow single HTML tags to be extended and enhanced. However, the DHTML behaviors ultimately only extend, enhance, or group together existing behaviors of the core engine. DHTML behaviors are more of a tool to supplement or group together existing behaviors supported by the core engine than a mechanism to develop radically new behaviors. That is, DHTML behaviors allow content authors to approach existing behaviors in a dynamic way, as opposed to creating new behaviors that may be based on, utilize, or otherwise participate with existing behaviors supported by the core engine.
A third approach supported by the prior art to extend behaviors is known as Object Linking and Embedding (OLE). OLE is not specific to markup languages, however. Rather, OLE allows binary software objects with well-defined properties and I/O interfaces to be reused. In the context of HTML, they can be referred to within HTML code in a similar manner to which plug-ins are referenced. While they provide full extensibility of existing behaviors of the core engine, they cannot participate with existing behaviors, but rather replace them, like plug-ins. As such a wholesale approach to behavior extensibility, OLE objects cannot be used to supplement existing behaviors in a minor, albeit subjectively important to the content author, way. OLE objects can be viewed as a plug-in-like technology, but which is based on software objects, instead of software programs, as plug-ins are.
Content authors, therefore, are currently presented with prior art extensibility of behaviors that may not represent how they actually want to extend those behaviors. Minor supplementation and aggregation of existing behaviors can be accomplished by using DHTML behaviors. Complete wholesale replacement of existing behaviors, and providing new behaviors without participation with existing behaviors, can be accomplished by using plug-ins or OLE objects. However, content authors cannot within the prior art provide extended behaviors that participate with existing behaviors beyond the limited supplementation and aggregation supported by DHTML behaviors. While content authors can create completely new behaviors using plug-ins or OLE, these new behaviors cannot be based on and thus cannot participate with existing behaviors.
One or more embodiments relate to extensible markup language layout and rendering behaviors. A core engine provides existing layout and rendering behaviors for a predetermined markup language, such as HTML. External components are designed to provide extended layout and/or rendering behaviors, in addition to the behaviors of the core engine. A mechanism, which can be part of (included in) the core engine, extends the existing behaviors with the behaviors of the external components. The external components can participate with the functionality of the core engine. They can completely replace comparable functionality provided by the existing behaviors, or can supplement the existing behaviors by participating in their layout or rendering process.
To extend a comparable behavior of the core engine with a behavior of an external component, the mechanism does the following. It calls a behavior initialization method of the external component to learn how the external component's behavior wants to participate with the core engine's comparable behavior. Once this is known, the mechanism then calls a behavior method of the external component that provides the behavior when the core engine is providing the comparable behavior. As a result, the external components' behavior participates with the core engine's comparable behavior. In addition, the mechanism may receive calls from the external component to a corresponding behavior method of the mechanism. This allows the external component to communicate with the core engine during participation of the external component's behavior with the core engine's comparable behavior.
One embodiment provides for advantages not found within the prior art. Complete participation with existing behaviors can be accomplished by the extended behaviors of external components. This is in distinction with DHTML behaviors, which can only accomplish such participation on a limited basis, to supplement in a minor way or group existing behaviors. Furthermore, this is completely unlike extended behaviors that are supported by plug-ins or OLE objects, which cannot participate with existing behaviors at all. As a result, the extended behaviors give content authors a more complete solution to existing behavior extensibility. New behaviors can participate with existing behaviors as much or as little as is desired. The authors are not locked into providing only limited participation, as they are with DHTML behaviors, or never participating with existing behaviors, as they are with plug-ins and OLE objects.
Systems, methods, and computer and machine-readable media of varying scope are encompassed by one or more embodiments. Other aspects, embodiments and advantages, beyond those described here, will become apparent by reading the detailed description and by referencing the drawings.
In the following detailed description of various embodiments, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, specific embodiments. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments. Other embodiments may be utilized, and logical, mechanical, electrical, and other changes may be made without departing from the spirit or scope of the described subject matter. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the described embodiments is defined only by the appended claims.
For communication between the mechanism 202 and the external component 204, there is a pair of interfaces 206 and 208. The first interface 206 is exposed by the external component 204 for querying by the mechanism 202. The second interface 208 is exposed by the mechanism 202 for querying by the external component 204. The presence of two interfaces allows the external component 204 to process a behavior to any degree desired, since communication is two-way between the external component 204 and the mechanism 202. For example, the behaviors supported by the external component 204 may completely override comparable behaviors supported by the core engine 102. Alternatively, the behaviors supported by the component 204 may complement, or supplement, the comparable behaviors of the core engine 102. That is, the behaviors of the external component 204 can participate with the behaviors of the core engine 102 to any degree. It is noted that the pair of interfaces 206 and 208 for purposes of extended behaviors is in addition to other, known interfaces that may already be present for communication between the core engine 102 and the mechanism 202. These other, known interfaces are not shown in
The behaviors supported by the external component 204 can be layout behaviors or rendering behaviors. Rendering behaviors generally are behaviors that specify how markup language elements are to be rendered, or drawn, on the medium 106. Layout behaviors generally are behaviors that specify how markup language elements are to be laid out, or positioned and sized, on the medium 106. Each of these behaviors can be attached behaviors or element behaviors. Attached behaviors are attached in a non-permanent manner to a markup language element. An element in a markup language is a discrete entity that can be any content contained between the tags, and any attributes the tags may have. Such behaviors can be applied, or mapped, to an element, and subsequently removed from the element. Conversely, element behaviors are permanently attached to a markup language element. They cannot be later removed once applied to an element.
An example of how a behavior supported by the external component 204 can be an attached behavior applied and then unapplied to an HTML element is:
<DIV STYLE=“behavior: url(http://www.abc.com/object.dll);”>
</DIV>
In this example, the behavior is implemented by the external component “object.dll”. This behavior is attached to the HTML element, and later unattached to the HTML element.
An example of how a behavior supported by the external component 204 can be an element behavior permanently applied to an HTML element is:
In this example, “foo” is identified as a namespace, such that all the tags associated with this namespace are implemented by the external component “object.dll”. This behavior is attached to the element “bar” in the “foo” namespace. As an element behavior, it cannot be unattached to the HTML element once it has been attached.
The mechanism then calls a behavior initialization method of the first interface 206 in 404. In response to this call, the external component 204 indicates the type of extended behavior that it is supporting, either a layout behavior or a rendering behavior. The external component 204 also indicates how this behavior of the component 204 will participate with the comparable behavior of the core engine 102. The comparable behavior of the core engine 102 is the behavior of the core engine 102 that the extended behavior supported by the external component 204 is replacing, supplementing, complementing, or to which the extended behavior otherwise relates.
Where the behavior supported by the external component 204 is a layout behavior, participation of this behavior with the comparable behavior of the core engine 102 is preferably in one of two ways. First, the behavior can be fully delegated to the external component 204 from the core engine 102. Second, the behavior implemented by the external component 204 can be called after the comparable behavior of the core engine 102 is performed. A complete example of such layout behaviors is presented in a subsequent section of the detailed description.
Where the behavior supported by the external component 204 is a rendering behavior, participation of this behavior with the comparable behavior of the core engine 102 is also preferably in one of two ways. First, the rendering by the behavior of the external component 204 can completely replace rendering by the comparable behavior of the core engine 102. Second, the rendering by the behavior of the external component 204 can be interspersed with rendering by the comparable behavior of the core engine 102. A complete example of such rendering behaviors is also presented in a subsequent section of the detailed description.
As necessary, the mechanism calls a behavior method of the first interface 206 in 406. The behavior method is called when the core engine 102 is providing the comparable behaviors to the behavior of the external component 204. This is done so that the behavior of the external component 204 can participate in processing with the comparable behaviors of the core engine 102. Similarly, the mechanism receives calls from the external component 204 to a corresponding behavior method of the second interface 208 in 408. When the external component 204 needs to submit information to the core engine 102, it calls this method of the second interface 208. This is also done so that the behavior of the external component 204 can properly participate with the comparable behaviors of the core engine 102. Examples of behavior methods of the first interface 206 and of corresponding behaviors methods of the second interface 208 are described in subsequent sections of the detailed description, with respect to layout and rendering behaviors.
Extended rendering behaviors supported by the external component 204 are described in this section of the detailed description.
Rendering behaviors supported by the external component 204 can interact with the different layers of the diagram 500 in two primary ways. First, the behaviors can intersperse their drawing with the rendering performed by the behaviors of the core engine 102. Second, the behaviors can effect wholesale replacement of the drawing process from the behaviors of the core engine 102. With respect to the former, the rendering behaviors supported by the external component 204 can draw below the content, after the background layer 508 is drawn, as indicated by the arrow 520. The rendering behaviors can also draw below the flow layer 504, where the behavior is called after the elements with a negative z-index are drawn, as indicated by the arrow 518. The rendering behaviors can draw above the flow layer, after the elements of the low are drawn, as indicated by the arrow 516. Finally, the rendering behaviors can draw above the content, after the elements with a positive z-index are drawn, as indicated by the arrow 514.
With respect to wholesale replacement of the drawing process, the rendering behaviors supported by the external component 204 can replace the drawing of all the layers 502, 504, 506, and 508, as indicated by the curved bracket 522. The rendering behaviors can also replace just the content layers 502, 504, and 506, as indicated by the curved bracket 510. Finally, the rendering behaviors supported by the external component 204 may replace only the background layer 508, as indicated by the arrow 512. Two options not indicated in the diagram 500 of
As has been described in conjunction with
The IHTMLPainter interface is specified as follows.
This structure allows the behavior to convey information to the core engine. The fields are defined as follows.
The IHTMLPainter interface has four methods: Draw, GetPainterInfo, HitTestPoint, and OnResize. The Draw method corresponds to what has been referred to as the behavior method of the first interface 206 in 406 of
With respect to the GetPainterInfo method, the mechanism 202 that can be a part of the core engine 102 calls this method to determine how the behavior of the external component 204 desires to participate in the rendering process. In particular, the external component 204 returns information in the structure HTML PAINTER INFO. The IFlags are a combination of the following.
The surfaces referred to can be DirectDraw surfaces, as known within the art. The DC referred to is a device context, as known within the art. The LZOrder indicates the drawing layer at which the Draw method should be called. This can be one of the following.
The iidDrawObject refers to the type of surface that is desired by the external component 204. For example, if the component 204 wishes to draw to a specific type of DrawObject, which is a known type of object, this is the interface identifier, or IID, of that object. If the component draws to a GDI device context, which is a known type of context, this is all zeros. Finally, rcExpand indicates the number of pixels needed on each side of the standard drawing rectangle for drawing outside of the rectangle. For example, the external component 204 in an editing framework may wish to draw a hatched border outside an element, to indicate that the element has been selected for editing.
With respect to the Draw method, when the core engine 102 is performing the rendering process, the Draw method is called as has been requested by the external component 204. The external component 204 can thus participate at any level of granularity within the rendering process. The rectangle rcBounds indicates where on the surface, relative to the device context's origin, the external component 204 should draw. The rectangle rcUpdate indicates what actually needs to be drawn—needs to be updated—relative to the device context's origin. Either hdc or pvDrawObject is non-null, and is the surface on which the external component 204 actually draws. If the component 204 has previously requested a particular DrawObject, then pvDrawObject will point to such an object, and hdc will be null. Otherwise, hdc is a handle to a GDI device context, and pvDrawObject is null. The LDrawFlags are set to any combination of the following flags.
The former flag indicates if the update region is different than as specified by rcUpdate. The latter flag indicates that a transform, such as zoom or rotation, is in effect.
With respect to the HitTestPoint method, this method is called to decide if a given point, such as the point under the pointer, hits the component (i.e., is drawn by the external component 204). The HitTestPoint method thus lets the external component 204 to react to its element being hit. pt indicates the point that has been hit. If a hit actually has occurred, as determined by the external component 204, then pbHit is returned as true. If a particular part of an element has been hit, then the part is identified using plPartID.
Finally, with respect to the OnResize method, this method is called whenever the element controlled by the external component 204 has been resized. The core engine 102, through the mechanism 202 calling this method, also informs the external component 204 of the new size.
The IHTMLPainterSite interface is specified as follows.
The information is returned in the following structure:
The IHTMLPainterSite interface has seven methods: InvalidatePainterinfo, InvalidateRect, InvalidateRegion, GetDrawInfo, TransformGlobaltoLocal, TransformLocaltoGlobal, and GetHitTestCookie. Each of these methods corresponds to what has been referred to as the corresponding behavior method of the second interface 208 in 408 of
With respect to the InvalidatePainterinfo method, the external component 204 calls this method when any of the information it has previously supplied in response to a GetPainterInfo method call is out of date. In response, the mechanism 202 that can be part of the core engine 102 will call the GetPainterInfo method to acquire the up-to-date information. With respect to the InvalidateRect method, the external component 204 calls this method when its picture is out of date, as specified by a rectangle. This invalidates its rectangle, and forces the mechanism 202 that can be part of the core engine 102 to force a draw. With respect to the InvalidateRegion method, the external component 204 similarly calls this method when its picture is out of date, but as specified by a non-rectangular region.
With respect to the GetDrawInfo method, the external component 204 calls this method to receive the additional information that has been indicated as available when the mechanism 202 called the Draw method of the external component 204. The LFlags can be set by a combination of the following:
The rcViewPort is the part of a region that is currently in view. For example, when the scrollable, the part in the window that is currently visible is specified by the rcViewPort. This is useful to the external component 204 if it wishes to draw a fixed background, such as a watermark, behind scrollable content. hrgnUpdate is the update region, describing the minimal surface area that needs repainting, and is contained within the rcUpdate passed to the Draw method. xform is the transformation matrix that is applied to the drawing coordinates before rendering. This is an affine linear transformation in the following format.
With respect to the TransformGlobalToLocal and the TransformLocalToGlobal methods, these methods are called to transform a point in global coordinates to local coordinates, and vice-versa. Finally, with respect to the GetHitTestCookie method, if the external component 204 needs to know the identifier of the element that was hit before deciding if it is in fact hit, the external component 204 calls this method. For example, the external component 204 may need to call this method to maintain its own internal data structures, or those of a framework to which it belongs.
The IHTMLPainterEventInfo is specified as follows.
The IHTMLPainterEventInfo interface allows the external component 204 to participate more fully in special forms of rendering and hit testing. This interface is used primarily to participate in editing frameworks. The interface has four methods: GetEventInfoFlags, GetEventTarget, SetCursor, and StringFromPartID. Each of these methods can correspond to what has been referred to as the behavior method of the first interface 206 in 406 of
With respect to the GetEventInfoFlags method, the external component 204 describes how it wants to participate by setting a combination of the following flags.
With respect to the GetEventTarget method, when the external component 204 returns true from a hit test, the core engine 102 may fire events as a result. These events are normally fired on the element to which the component 204 is attached. The component 204, however, can cause them to be fired on a different element, by returning that element in this method.
With respect to the SetCursor method, after a successful hit, the core engine 102 calls this method to give the external component 204 an opportunity to change the cursor, by passing in the partID the element returned in HitTestPoint. Finally, with respect to the StringFromPartID method, this method extends a known method IHTMLElement:: componentFromPoint to rendering behaviors. If the point belongs to an external component 204, this method is called to ask the component for the name of the part that was hit.
The IHTMLPainterOverlay interface is specified as follows.
This interface is supported by the external component 204 if it supports a rendering behavior that wishes to use a hardware overlay buffer. The interface has one method, OnMove, which can correspond to what has been referred to as the behavior method of the first interface 206 in 406 of
Extended layout behaviors supported by the external component 204 are described in this section of the detailed description. The behaviors can use the interfaces described in this section to specify their size and position. Furthermore, the behaviors can use the interfaces described in this section to modify their natural size in order to have more or less space allocated to them.
Layout behaviors supported by the external component 204 can interact with the natural sizing of elements that is normally performed by the core engine 102 in three ways. First, layout can be completely delegated to the external component 204. Second, layout can be modified by the external component 204 after the core engine has proposed a natural size for the element. Third, the layout behavior can specify that it is also a rendering behavior that needs additional space outside the element's borders.
As has been described in conjunction with
The IElementBehaviorLayout interface is specified as follows.
The interface has four methods: GetLayoutInfo, GetSize, GetPosition, and MapSize. The GetLayoutInfo method corresponds to what has been referred to as the behavior initialization method of the first interface 206 in 404 of
With respect to the GetLayoutInfo method, the mechanism 202 that can be a part of the core engine 102 calls this method to determine whether the external component 204 wants to participate in layout participation either before and/or after natural sizing occurs by the core engine 102. There are three values that are recognized, as follows.
If FULLDELEGATION is specified, then MODIFYNATURAL is ignored.
With respect to the GetSize method, the mechanism 202 calls this method when it needs to determine the size of the element controlled by the external component 204. The LCalcMode parameter passed to this method is used to determine the layout mode, which can be minimum, min-max, or natural sizing passes. These enumerated values describe the various layout passes the layout may put its element through. These are the following layout calculation modes.
sizeContent refers to the default size. The first ptOffset refers to the location of the content, whereas the second ptOffset refers to the location of the bounding box. psize refers to the size of the bounding box.
During layout of the element, before entering the core engine's own CalcSize method, the behavior's GetSize method is synchronously called if the behavior registered for full delegation. The behavior is passed the proposed size, which is the size of the parent element, and the returned size is actually used as the element's size. If full delegation has been requested, natural sizing is skipped, however. Otherwise, natural sizing occurs first, and then during the CalcSize call, just before returning, the behavior's GetSize method is called. The behavior is passed the proposed size, as well as the natural size of the content alone. The behavior has an opportunity to modify the element's size, before CalcSize is returned from.
With respect to the GetPosition method, the mechanism 202 calls this method when it needs to determine the position of the element controlled by the external component 204. lFlags are as specified in the previous section of the detailed description. pptTopLeft is the position of the upper left-hand corner relative to the parent of the current element. Finally, with respect to the Map Size method, the mechanism 202 calls this method only if the MAPSIZE flag has been turned on, where the layout behavior supported by the external component 204 is also a rendering behavior. With an input size specified by psizeIn, the method returns the actual rectangle needed as prcOut.
The IElementBehaviorSiteLayout interface is specified as follows.
This interface has three methods: InvalidateLayoutInfo, InvalidateSize, and GetMediaResolution. Each of these methods corresponds to what has been referred to as the corresponding behavior method of the second interface 208 in 408 of
With respect to the InvalidateLayoutInfo method, the external component 204 calls this method when its layout information is out of date. More specifically, this method is called to change the delegation mode. If the method is not called, changes to the delegation mode may not have any effect. With respect to the InvalidateSize method, the external component 204 calls this method when its size is out of date. More specifically, this method is called to indicate that the element's layout needs to be remeasured, and is treated as a forced remeasure request by the mechanism 202 and the core engine 102. Finally, with respect to the GetMediaResolution method, the external component 204 calls this method to retrieve the current measuring resolution, which is returned in units per inch for both the x and y directions. The current measuring resolution may change depending on whether the output medium is, for example, a display screen, as opposed to a page printed by a printer.
