Did you set any font when creating the form?

Usually forms work flawlessly across platforms when using the default font setting (in which case designer doesn't write any font into the .ui file)

Unfortunately this is not the case with Qt4. It writes font settings to the ui file even if one uses a default font. Another unfortunate thing is that on Windows the default font is MS Shell Dialog which is really a meta-font, so you can't copy it to a Unix box. If you manually delete font info from the ui, Qt will complain (I tried, with no success) and in 4.0.1 I didn't manage to enable font substitution using qtconfig, so there was no way to solve the font problem other than using a non-default font (one could substitute the font directly in the X server, but it is only a partial solution).

Oh, I see.

I'd consider this a severe bug, as it makes the whole basic idea of Qt - crossplatform development - unnecessary difficult.

You can patch it yourself

Why is that a problem? If you apply a layout to the window, it shouldn't matter at all.

It happens because you're using different styles which have different decorations.

I guess that if the layout would have been done under linux and then compiled on windows it would have better but again much larger on windows

No you didn't get the point.. You need to constrain the widgets to a layout and use spacers for the empty area's. This allows Qt to align the widgets correctly by itself. You believe it's a problem between platforms, but the same issue would also happen if you deside to use a different theme for your Windows application.

Select multiple widgets, right click, choose a layout. That's all, and Qt aligns stuff automatically.

Have you tried applying a different style to the form?
You should be able to apply a Windows style and force it to look like the original.

The thing to bear in mind is that cross platform doesn't mean "looks the same".
It means it runs without the need to change code.
Why would you want an application under KDE, Gnome or whatever to look like a windows application anyway?
The idea with Qt is that it will look like it fits into the host environment because it has the style built in and you can even define your own.

The issue you should be concerned with is the font not fitting into your combo boxes.
If you still want a windows appearance under an X desktop then look at the QStyle documentation.
Specifically you'll want to use QWindowsStyle.

I haven't tried to apply styles before, so I can't give you advice on it. Sorry

You can also preview the forms you create in designer using other styles to see what's likely to happen.
