Description
Displays the color-selection dialog.
Execute opens the color-selection dialog, returning true when the user selects a color and clicks OK, or false when the user cancels.
The code signatures of Execute that appear above are actually overrides of the Execute overloads in the base class Vcl.Dialogs.TCommonDialog.Execute. There is one more overload of Execute for Delphi that appears in the inherited members from TCommonDialog, and this overload takes no input parameters.
The ParentWnd parameter is a window handle of type HWND MSDN. If none is provided, the current form handle is used, accessed from Vcl.Forms.TApplication.ActiveFormHandle in the global variable Vcl.Forms.Application.
// Delphi: if ColorDialog1.Execute then Shape1.Brush.Color := ColorDialog1.Color else Shape1.Brush.Color := clGray;
// C++: if (ColorDialog1->Execute()) Shape1->Brush->Color = ColorDialog1->Color; else Shape1->Brush->Color = clGray;
