aNewControl A fully constructed control to place at aPaneId.
Returns:
The control which was at aPaneId.
Leave:
KErrNotFound This can occur before ownership of the new control is taken, if the subpane ID is not valid.
virtual IMPORT_C void CEikStatusPaneBase::SwitchLayoutL ( TInt  aLayoutResourceId  )  [virtual]
 

Switches to the specified status pane layout.

The actual layout to which this method switches may not be the same as specified in aLayoutResourceId parameter. Eg. if landscape mode status pane layout is set with this method, while in portrait mode, it's mapped to the corresponding layout in the portrait mode. This should be noted when using CEikStatusPaneBase::CurrentLayoutResId().

From S60 3.2 on the old status pane layouts are also mapped to the new layouts, ie. R_AVKON_STATUS_PANE_LAYOUT_USUAL -> R_AVKON_STATUS_PANE_LAYOUT_USUAL_EXT

R_AVKON_STATUS_PANE_LAYOUT_IDLE -> R_AVKON_STATUS_PANE_LAYOUT_IDLE_EXT

Parameters:
aLayoutResourceId Layout resource Id. This must be one of the layouts identified in the status pane resource structures, otherwise the function leaves KErrNotFound.
See also:
avkon.rsg
Leave:
KErrNotFound The specified layout does not exist in the status pane resource structures.
RWindowGroup * CEikStatusPaneBase::WindowGroup (   )  const [inline]
 

Provides access to a server-side window group.

Returns:
Pointer to the window group.
