TMenuItem.UpdateImages procedure
Update the images for the menu item and its child items.
Declaration
procedure UpdateImages(forced: Boolean=False)Arguments
forced | True causes an image assigned to Bitmap to be invalidated - even when an image list is not available or an image index has not been specified. |
Description
UpdateImages is a method used to ensure that changes to image
settings in the menu item (or its parent) are applied the menu item and its
child Items. It is called when a new image list is assigned to the owner Menu,
to the Parent menu item, or to the SubMenuImages for the menu item. It is also
called if the image width is changed (which causes the image list to be
updated).
Forced indicates whether an existing image assigned directly to
Bitmap is invalidated - even when an image list or image index is not available
for the menu item.
UpdateImages calls the UpdateImage method in the class instance to apply changes to Bitmap (when needed) and to notify the widget of the new icon. It calls the UpdateImages method for each of the Items to cascade the change to sub-menu items.
