[Info] Problems with FMX TSpeedButtons in Delphi 13.1

[Sergey Tkachenko]

You may notice that buttons in some FireMonkey demo projects look unusual: in addition to images from a TImageList, a flag icon is displayed on top of them.

This is caused by a bug in Delphi 13.1. Normally, the predefined button icons should be hidden when an image from a TImageList is assigned to the button.

This bug has been reported to Embarcadero, and hopefully it will be fixed in a future update.

As a workaround, you can use the code shown below. Assign the OnApplyStyleLookup event handler to all buttons that use images from a TImageList:

Code: Select all

procedure TfrmMain.btnApplyStyleLookup(Sender: TObject);
var
  Ico: TControl;
begin
  if (Sender as TStyledControl).FindStyleResource<TControl>('icon', Ico) then
    Ico.Visible := False;
end;

It really fixed, thank you. I was just about to write this question.
