Display settings and font size

[EdDressel]

Thank you for your response.

A couple of items in response:

1) Is this what you are recommending for ChangeScale:

Code: Select all

{$IFNDEF FMX}
procedure TCustomTeePanel.ChangeScale(M, D: Integer{$IFDEF D24}; isDpiChange: Boolean{$ENDIF});
begin
  inherited;

//  if M <> D then
//  begin
//    Canvas.FontZoom:=FView3DOptions.FontZoom*M/D;
//    FView3DOptions.FontZoom:=Round(Canvas.FontZoom);
//  end;
end;
{$ENDIF}

Do I also remove the "inherited;" as well?

2) Can you send attach a demo so I can test?

Much appreciated.

Hello,

Do I also remove the "inherited;" as well?

In the tests I've done here I don't see any difference but in general I would leave the inherited or remove the full override method.

Can you send attach a demo so I can test?

Sure. Here it is.

Thank you for the quick response.

Can I get the source to the demo as well?

Thank you.

From our testing, we believe it is fixed. We will be releasing it to our customers next week.

Hello,

This is just to inform another change had been introduced affecting DPI awareness and ChangeScale. This change entered the main branch a few days after v2021.33 was released so, if nothing changes, the next release will be the first to include this code:

Code: Select all

    {$IFNDEF FMX}
    procedure ChangeScale(M, D: Integer{$IFDEF D24}; isDpiChange: Boolean{$ENDIF}); override;
    {$ENDIF}

Code: Select all

{$IFNDEF FMX}
procedure TCustomTeePanel.ChangeScale(M, D: Integer{$IFDEF D24}; isDpiChange: Boolean{$ENDIF});
begin
  inherited;

  if not (csLoading in Self.ComponentState) and (M <> D) then
  begin
    Canvas.FontZoom:=MulDiv(FView3DOptions.FontZoom, M, D);
    FView3DOptions.FontZoom:=Round(Canvas.FontZoom);
  end;
end;
{$ENDIF}

It's basically the same code here with a new not (csLoading in Self.ComponentState) condition.
