How to remove focus rectangle from a button control?

Question

I need to remove a button focus rectangle, because it looks bad over the TBitBtn glyph after the buttons is clicked.

Answer 1

You can create an Interposer class for TBitBtn and override SetButtonStyle preventing it's internal IsFocused variable to be set:

type
  TBitBtn = class(Buttons.TBitBtn)
  protected
    procedure SetButtonStyle(ADefault: Boolean); override;
  end;

...
implementation

procedure TBitBtn.SetButtonStyle(ADefault: Boolean);
begin
  inherited SetButtonStyle(False);
end;

This will result a TBitBtn with no focus rectangle. (Tested with D7 - with/without Theme support).

Answer 2

As a workaround, you can use a TSpeedButton, which does not take the focus and, consequently, never receives a focus rectangle.
