I am trying to figure out how AlignControls works. The signature is: procedure AlignControls(aControl: TControl; var aRect: TRect); override;
What exactly is aControl for? Delphi's documentation says: AControl specifies the control that takes precedence in alignment when other controls have the same Align value. AControl can be nil Does it mean AControl is Nil when all controls have Align = alNone? The base method TWinControl.AlignControls is huge, over 700 lines, made by "ask". There is an error in wiki page: http://wiki.freepascal.org/Autosize_/_Layout which says: The layout is applied in the method TWinControl.AlignControls which can be overridden. For example TToolBar overrides that and defines a flow layout where controls that do not fit are put into subsequent lines. However, TToolBar does not have such method. There are only 2 components with overridden AlignControls, TScrollingWinControl where it only updates scrollbars, and TControlBar where is does nothing yet. I am thinking how to use it in TControlBar and maybe in TCoolBar. As you can see I am not very experienced component writer.
