Abstract

New varieties of child window controls are provided as system resources that application programs may exploit. The preferred embodiment of the present invention provides a dynamic link library (DLL) for implementing the new child window controls as part of an operating system. The new child window controls include a header bar control for providing header bars in application programs. The new controls also include a hot key control that allows a user to view and edit hot key combinations. The new controls further include a tab control for establishing tabs that differentiate amongst pages in user interfaces provided by application programs. An image list data type is defined and functions are provided for manipulating the image list data type. Image lists include multiple like-sized images that are stored efficiently in a single bitmap.
