This article describes a method for providing a common input programming interface to graphical controls in the OS/2 Presentation Manager environment. A control under the OS/2 Presentation Manager is a user interface element with a unique programming interface and application function such as a menu or scroll bar. When an application chooses to display a text or graphical item in a user interface control, it must send an input structure to the control. Each control supplied by the operating system requires a unique data structure to be filled by the application as input. For example, if an application wishes to display the same picture in both a menu and a list box, two unique data structures must be filled and sent to the two controls.
