Clipboard Operations

JADE rich text controls support standard clipboard operations and multiple levels of undo and redo operations, to a maximum of 100 undo or redo operations.

To perform a clipboard action

1. Right-click in the control. The context menu is then displayed.

2. Select the appropriate command in the context menu (if it is visible or enabled).

   The following clipboard commands may be available and enabled if another action has been performed (for example, you cannot perform a cut or copy action if no text is selected and the Redo command is disabled if you have not performed an Undo action).

   • Redo

   • Undo

   • Cut

   • Copy

   • Paste

The selected action is then performed.

From JADE 2020.0.01, you can programmatically paste from the Windows clipboard into a JadeRichText control.

• The canPaste_ method returns whether there is content such as text or an image in the Windows clipboard that can be pasted into the JadeRichText control. (You can also obtain this status by calling the JadeRichText class getRedoAndUndoState method.)

• If there is suitable content such as text or an image in the Windows clipboard, the paste_ method pastes that content into the JadeRichText control at the current cursor position. If the clipboard does not contain suitable content, the method does not result in any change. (This method is equivalent to selecting the Paste command in the context menu of the JadeRichText control at run time.)

Before you call the paste_ method, call the canPaste_ method to confirm there is suitable content available.
