IDisplayPointer interface
Provides methods that control display pointers so that you can mark sections of an HTML document for editing based on the on-screen rendering of a document.
Members
The IDisplayPointer interface inherits from the IUnknown interface. IDisplayPointer also has these types of members:
- Methods
Methods
The IDisplayPointer interface has these methods.
| Method | Description |
|---|---|
| GetDisplayGravity | Gets the display gravity for the display pointer. |
| GetFlowElement | Gets the innermost element containing the display pointer that is a flow layout element. |
| GetLineInfo | Gets information about the line that the display pointer is on. |
| GetPointerGravity | Gets the pointer gravity for the display pointer. |
| IsAtBOL | Determines whether the display pointer is at the beginning of a line. |
| IsEqualTo | Determines whether two display pointers specify the same position in the markup of an HTML document. |
| IsLeftOf | Determines whether the display pointer that this interface refers to is to the left of another one. |
| IsPositioned | Determines whether the display pointer has been positioned. |
| IsRightOf | Determines whether the display pointer that this interface refers to is to the right of another one. |
| MoveToMarkupPointer | Moves this display pointer to the position of a markup pointer. |
| MoveToPoint | Moves this display pointer to the specified coordinates on a page. |
| MoveToPointer | Moves this display pointer to the position of another display pointer. |
| MoveUnit | Moves a display pointer to the specified position. |
| PositionMarkupPointer | Positions a markup pointer at the location of the display pointer to which this interface refers. |
| QueryBreaks | Determines whether a line break or a block break, if any, occurs at the display pointer's location. |
| ScrollIntoView | Scrolls the location that is indicated by the display pointer into view. |
| SetDisplayGravity | Sets the display gravity for the display pointer. |
| SetPointerGravity | Sets the pointer gravity for the display pointer. |
| Unposition | Sets the display pointer to an unpositioned state. |
Remarks
IDisplayServices and IDisplayPointer work with markup pointer (IMarkupServices2, IMarkupContainer2, and IMarkupPointer2) to give you editing control that includes information about how a document is rendered on the screen, and the horizontal and vertical positioning of elements and lines of text. These interfaces enable you to translate a user's on-screen input (for instance, a mouse click near a line of text) into editing operations.
Use the IDisplayServices::CreateDisplayPointer method to create IDisplayPointer interface pointers.
