An AV occurs when changing a toolbar pop-up menu's UI scale factor if the menu is not associated with a bar manager component

created 5 years ago

Hello,

please Change the code

procedure TdxBarCustomPopupMenuComponent.ChangeScaleCore(M, D: Integer);
begin
  inherited ChangeScaleCore(M, D);
  if UseOwnFont or not ScaleFactor.Equals(BarManager.ScaleFactor) then
  Font.Height := MulDiv(Font.Height, M, D);
end;

to

procedure TdxBarCustomPopupMenuComponent.ChangeScaleCore(M, D: Integer);
begin
  inherited ChangeScaleCore(M, D);
  //if UseOwnFont or not ScaleFactor.Equals(BarManager.ScaleFactor) then
  if UseOwnFont or (Assigned(BarManager) and not ScaleFactor.Equals(BarManager.ScaleFactor)) then
  Font.Height := MulDiv(Font.Height, M, D);
end; .

I have set dpi to 125% and find no Popupmenu on my form. But I get an error because  a PopupMenu doesn't have a BarManger assigned.

Thanks

Günter Keitel
