Visual Components are implemented in FRE for Windows.
- The standard part of the context menu is the context menu which is displayed in the component by default. This part cannot be changed. You can only display or hide from the display this part of the menu using the StandardMenuEnabled property.
- The custom part of the context menu can be edited. By default, it is empty. You can add any of the standard commands available for the component or any custom commands to this part of the context menu. The custom part of the context menu is always displayed after the standard part. The custom part of the context menu can be enabled or disabled too — use the CustomMenuEnabled property. Note that all indexed properties and methods use the index in the collection of commands in the custom part of the context menu.
The following Visual Components have a context menu: ImageViewer, ZoomViewer, TextEditor, DocumentViewer. See the list of available commands and the commands which can be used in the context menu:
