RectIsEditable Property (GdViewer)

In This Topic
Determines, if the rectangle of area selection can be moved or resized (edited) by a user. You are allowed to edit the rectangle using the mouse when the MouseMode property is set to GdPicture14.ViewerMouseMode.MouseModeAreaSelection.

You can find out, if this rectangle is currently defined and drawn within the GdViewer control, using the IsRect method. The rectangle of selection always relates to the document currently displayed in the GdViewer control.
