CustomControls: UI Control Framework example code
CustomControls demonstrates customised simple and
compound UI Control Framework control classes. Compound controls are used as
on-screen containers for other controls, either simple or compound. The custom
controls are subclasses of the class
implementations of its virtual functions for construction, drawing, and
accepting user input.
Note that the
CustomControls example has dependencies on GUI components that may not be present on all Symbian OS licensee SDKs.
When the application starts, it displays two smiling faces (smiley) controls. The mood of the smileys can be changed by selecting a smiley using the left/right keys or pointer, and pressing space/clicking. A dialog containing the smiley controls can be started from the application’s menu.
All of the examples use the following classes:
CCoeControl: control base class, implemented by
MCoeControlObserver: interface class for classes
interested in events reported by controls. Implemented by
CEikDialog: dialog base class, implemented by
CSmileyDialog. This is used to show how controls can be added to
CEikApplication: application framework base classes. Implemented
