Attaches aCompoundControl to the layout manager. Is normally not called manually since CCoeControl::SetLayoutManagerL() calls this function. Once a compound control is attached to a layout manager, the layout manager owns itself. Detach()

CCoeControl::SetLayoutManagerL()

Calculates the minimum size of aCompoundControl Is normally not called manually since CCoeControl::MinimumSize() calls this function in the default implementation on controls with layout managers.

To calculate the minimum size is almost as time consuming as performing an actual layout and should be used with caution. The minimum size depends on aCompoundControl's maximum width. CCoeControl::MaximumWidth()

The minimum size

Gets the offset to the first text baseline relative to the top of the control.

The baseline

CCoeControl::TextBaselineOffset()

Determines if it is possible to attach another control to the layout manager. ETrue if possible, otherwise EFalse

Detaches aCompoundControl from the layout manager. Is normally not called manually since CCoeControl::SetLayoutManagerL() calls this function when you switch layout managers on a control. It is also called from CCoeControl::~CCoeControl When the last attached compound control detaches, the layout manager deletes itself. CCoeControl::SetLayoutManagerL()

Handles when a component control is added to an attached compound control Is normally not called manually since CCoeControlArray::InsertLC() calls this function for controls with layout managers. Is used by layout managers to prepare to layout one more component control. CCoeControlArray::InsertLC()

Handles when a component control is replaced by another component control in an attached compound control

Is not called by CCoeControl. Is used by layout managers to move settings and similar that are specified for aOldControl to aNewControl If this function is called, neither HandleAddedControlL nor HandleRemovedControl is allowed to be called. KErrNone if no error. KErrNotFound if the layout manager cannot find aOldControl

Handles when a component control is removed from an attached compound control Is normally not called manually since CCoeControlArray::Remove() calls this function for controls with layout managers. Is used by layout managers to remove all settings and similar that are specific for aRemovedControl. CCoeControlArray::Remove()

Performs the layout of the attached controls Is normally not called manually since CCoeControl::SizeChanged() calls this function in the default implementation on controls with layout managers.

The layout is generally performed by calling the component controls' SetMaximumWidth(), followed by MinimumSize(), and then the layout manager tries to place the component controls according to their minimum sizes and the settings.
