Need to Remove the PixelsPerInch and TextHeight fake properties

[Javier Tarí 23]

Hello,

When you save a form, there are two fake properties saved,  PixelsPerInch and TextHeight. That would be fine, but when making changes on two different systems, one with W7 and other with W10, each saves a different set of values, and that generates false Git differences on the DFMs

 

We never use TForm in any of our projects, but rather an own descendant, so we can change it if that's needed to remove those fake properties

 

Both are not true properties; TCustomForm saves them the DFM using this method:

procedure TCustomForm.DefineProperties(Filer: TFiler);
begin
  inherited DefineProperties(Filer);
  Filer.DefineProperty('PixelsPerInch', nil, WritePixelsPerInch, not IsControl);
  Filer.DefineProperty('TextHeight', ReadTextHeight, WriteTextHeight, not IsControl);
  Filer.DefineProperty('IgnoreFontProperty', ReadIgnoreFontProperty, nil, False);
end;

I can't find any way of avoiding them to be saved on the DFM

 

Can you help me?

 

Thank you

If you remove PixelsPerInch from the DFM then you'll find that your form layouts break different devs modify forms if their machines use different font scaling (i.e. DPI) settings.

 

In my workplace we handle this by requiring all modifications of forms to be made using a common font scaling setting.

In fact, in my case it doesn't ; I've tried removing it and reopening, and the result was the same. I forgot telling that we have "scaled=false" in all forms

We have 1920x1080 in all monitors (27" to 32" monitors); before it had different font scaling i.e. W7 = 100% , W10=150%; tried changing the W7 to 150% as well, and the result was no visible changes, and no changed either on the PixelPerInch and TextHeight saved values

OK, Scaled = False does change things.

While Scaled = False is not the suggested standard, is removing these properties still a general solution or does it only work for your use case?

[Javier Tarí 23]

I don't want to use the automatic scaling; eventually I'll use a customized scaling, so the PixelsPerInch and TextHeight properties are useless to me, and right now they just give fake changes on source control

 

That's why I'd like to get rid of them
