A TColorListBox tcolorlistbox.png is a component that shows a (scrollable) list of colors from which the user can select one. It is available from the Additional tab of the Component Palette.

Specific properties of TColorListBox are:

  • ColorRectOffset - margin around each color rectangle
  • ColorRectWidth - width of a color rectangle
  • Style - defines the items shown in the listbox, and how the colors are named
    • cbStandardColors - includes the 16 LCL standard colors in the list, e.g. clRed or clBlue
    • cbExtendedColors - includes the 4 LCL extended colors: clMoneyGreen, clSkyBlue, clCream, clMedGray
    • cbSystemColors - includes the OS- and theme-dependent system colors
    • cbIncludeNone - includes the special color clNone. Use the property NoneColorColor to determine the replacement color. If NoneColorColor is set to clNone the color rectangle displays a crossed-out box like in many drawing programs.
    • cbIncludeDefault - include the special color clDefault. Property DefaultColorColor determines the actual color displayed.
    • cbCustomColor - the first listbox item is customizable by means of the standard color dialog.
    • cbPrettyNames - displays "pretty" color names next to the color boxes, e.g. 'Red'. Without this option the internal color names are used, e.g. 'clRed'.
    • cbCustomColors - includes user-provided colors at the end of the list. The colors must be defined by a stringlist in the OnGetColors event, like this:
  procedure TForm1.ColorListBox1GetColors(Sender: TCustomColorListBox; Items: TStrings);
  begin
    Items.AddObject('Gold', TObject(PtrInt($00D7FF)));
    Items.AddObject('Chocolate', TObject(PtrInt($1E69D2)));
    Items.AddObject('Light blue', TObject(PtrInt($E6D8AD)));  
  end;
