TrvActionCustomColor.CallerControl

Specifies the control (for example a toolbar button) which executed this action.

property CallerControl: TControl;

Assign this property if you use Delphi 4 or 5. For the newer versions of Delphi, the caller control is determined automatically (using ActionComponent property).

A color-picker window is positioned relative to this control. If this control is undefined, a color-picker window is displayed at the mouse pointer position.
