This example demonstrates a minimal UI application without the use of resource files. It implements the standard classes required by the UI framework of any application; application, document, application UI and view, all of which are implemented minimally.
The application class implements the following required functions:
Because the application does not use a resource file, it
also needs to override CEikApplication::ResourceFileName()
, to return an empty resource filename.
The document class must implement CEikDocument::CreateAppUiL()
.
The app UI class implements the following required functions:
A ConstructL()
. This must call CEikAppUi::BaseConstructL()
. The ENoAppResourceFile
flag is used to indicate that it has
no resource file, and ENoScreenFurniture
indicates
that it does not require any resource independent 'screen furniture',
for example status bars. ConstructL()
is also used
to create any views owned by the app UI.
A destructor, to delete the view.
A HandleCommandL()
This app UI only handles a single command, to exit the application.
Views are controls, derived from CCoeControl
. Their main purpose is to display the application's data and to
handle input. This view overrides CCoeControl::Draw()
, to display a message in the centre of the screen rectangle. It
does not handle any key or pen input.
The Symbian build process describes how to build an application.
The Minimal
example builds an executable
called Minimal.exe
in the standard location (\epoc32\release\winscw\
<build_variant> for
CodeWarrior). Either launch the executable itself, or launch the emulator
and then select the Minimal
application from
the Emulator's extras bar.
