The Symbian platform provides AVKON controls, which are a convenient set of UI components designed specifically for devices based on the Symbian platform.
Commonly used AVKON controls include:
dialogs
editors
forms
grids
lists
notes
pop-up lists
queries
setting pages
For more information, about how to use these controls, see Symbian C++ API specifications.
All of the AVKON resources listed above, except dialogs, queries and notes, are non-window-owning controls. This means that they cannot exist on the screen without being inside another control.
Note: Since AVKON UI resources scale automatically according to screen
resolution and orientation, it is recommended that you consider using
AVKON or AVKON-derived components in your application UI as they may
require less implementation effort. Custom CCoeControl-derived controls may require additional efforts to support scalability and themes.
