TFileListBox.OnDrawItem property
Handler for painting of a list item in owner-draw mode.
Declaration
property OnDrawItem:;Description
OnDrawItem is a
TDrawItemEvent property with the event
handler signalled to render a list item when an owner-drawn method is used in
the
Style property. OnDrawItem is signalled (when assigned) from
the
DrawItem method. DrawItem provides the arguments for the event
handler.
An application should implement an object procedure to respond to the event notification. Use the Canvas for the control to get text metrics or render the control and any graphic images. An internal drawing routine which uses the Font, Color, Layout and Alignment in the control is called when OnDrawItem has not been assigned.
This description is the one of StdCtrls.TCustomListBox.OnDrawItem.
