Controls

The term control refers to a rectangular area of the display that may respond to user input events. A control provides a means of access to a window, which means it can be drawn onto the window and receive input.

Controls are derived from CCoeControl.

Examples of controls include:

• buttons

• menus

• text edit boxes

• main panes that display application specific data
