qdelete [widget] qdelete [treeitem] qdelete [tableitem] |
Description
The qdelete deletes an widget or item from memory. Any children the widget may have are also deleted. If the object is drawn on the screen it will be erased.
To make a widget invisible without deleting it use the qclose command. Many applications do not need qdelete, but rely on qshow, qclose, and qraise to manage visibility/invisibility issues.
Arguments
widget

treeitem
An item in a qtreewidget. If this argument is omitted the current treeitem will be used.
tableitem
An item in a qtablewidget. If this argument is omitted the current tableitem will be used.
