MSHTML Editing Reference

This section contains reference information for MSHTML Editing.

Interfaces

IDisplayPointer

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.

IDisplayServices

Provides methods that enable the user to work with display pointers and the insertion point as they relate to the on-screen layout.

IElementSegment

This interface provides methods that control a fragment of HTML markup in the current editable selection that consists of a single element.

IHighlightRenderingServices

This interface provides methods that enable you to control which sections of a document are highlighted on the screen and the style of highlighting.

IHighlightSegment

This interface enables you to control a highlighted section of a document.

IHTMLCaret

Provides methods that control the insertion point (caret) in the editor.

IHTMLChangeLog

Provides a method to get information stored in a change log about the changes in a markup container.

IHTMLChangePlayback

Provides a method to play back change records from a change log.

IHTMLChangeSink

Provides notification when a change has occurred in the contents of a markup container.

IHtmlDlgSafeHelper

Provides methods to programmatically access the color dialog box, the block format collection, and the fonts collection.

IHTMLEditDesigner

Provides methods that enable clients using the editor to intercept Windows Internet Explorer events so that they can change the default behavior of the editor.

IHTMLEditHost

Provides a method to customize the way that elements are resized and moved.

IHTMLEditHost2

Extends IHTMLEditHost with a method that enables you to intercept drag-and-drop operations at a stage earlier than the ondragstart event.

IHTMLEditServices

Provides methods that enable you to add or remove edit designers, and to control the current selection.

IHTMLEditServices2

Extends IHTMLEditServices.

IHTMLPainter

This custom interface provides methods to MSHTML so that it can draw a rendering behavior.

IHTMLPainterEventInfo

This custom interface provides methods to MSHTML so that a rendering behavior can provide certain special event handling.

IHTMLPainterOverlay

This custom interface provides a method to MSHTML that enables a rendering behavior to use the Microsoft DirectDraw hardware overlay buffer, if the buffer is present.

IHTMLPaintSite

This interface provides methods that enable a rendering behavior to communicate with MSHTML from within the behavior's implementation of the IHTMLPainter::Draw and IHTMLPainter::HitTestPoint methods.

IIMEServices

This interface enables an Active Input Method Editor to access the Active Input Method Manager.

ILineInfo

This interface provides properties that contain information about a line of text in a rendered HTML document.

IMarkupContainer

This interface is an object representing the organization of elements and text in a page.

IMarkupContainer2

This interface provides methods that control a markup container.

IMarkupPointer

This interface, along with the IMarkupServices interface, allows the contents of the page to be programmatically manipulated from your C++ program.

IMarkupPointer2

This interface provides methods that move a markup pointer within a markup container and gather information about the contents of the container.

IMarkupServices

This interface, along with the IMarkupPointer interface, allows the contents of the page to be programmatically manipulated from your C++ program.

IMarkupServices2

This interface provides methods, along with the IMarkupContainer2 and IMarkupPointer2 interfaces, that enable you to edit the contents of an HTML document from your C++ program.

IMarkupTextFrags

This interface provides methods that enable you to insert and remove text from a markup container that is not a part of the actual markup in the container. These text fragments are attached to the content of a markup container, but are not a part of the container itself. They are not represented in the tree for the document. They are, however, saved to the document when the document is saved (for instance, by sending the command IDM_SAVE or IDM_SAVEAS through the IOleCommandTarget interface).

ISegment

This interface provides a method that creates containers (segments) for fragments of HTML markup in the current editable selection. These segments can include both a range of elements and element fragments.

ISegmentList

This interface provides methods that access information about a list of the segments in the current selection.

ISegmentListIterator

This interface provides methods that enable you to traverse a segment list represented by an ISegmentList interface and retrieve its individual members.

ISelectionServices

This interface provides methods to programmatically clear, add content to, and remove content from the selection object.

ISelectionServicesListener

This custom interface provides methods that the editing component of MSHTML calls whenever certain events fire for a selection object that has a registered ISelectionServicesListener interface. This interface provides processing for undo events, for selection type changes, and whenever the mouse pointer exits the scope of an element in the editable selection. An application should supply an implementation of this interface for a selection object so that the editing component of MSHTML can respond to these events.

Structures
