TIcon.Handle property

Member of TIconpublicIn unit Graphics

Handle used to access the image data for the icon.

Declaration

pascal
property Handle: HICON read GetIconHandle write SetIconHandle;

Description

Handle is a HICON property which contains the handle for the icon used to access its image data. The property value is provided by the inherited GetHandle method, and contains the handle for its TSharedRasterImage instance.

Setting a new value for the property causes the previous handle and the canvas device context to be freed. The previous image is cleared and unshared as well.

The inherited UpdateHandle method is called to apply the new handle to the shared image, and to load its icon data.
