Font scaling and custom QFileDialog
Hi!
I have two question and thought it would be better if I ask them in the same thread, hope it's ok!
1. Font scaling with resolution
Is it possible to assign different font size depending of the screen resolution? (not when resizing window)
I was thinking of detecting the screen size when launching the application and then attributing a correct font size depending of the resolution. But I'm afraid this will mess with the layouts and other elements, like the font overflowing neighboring elements, or words being cut in half...
I use a fairly large screen myself, but some of my users use really giant screens and the fonts are quite tiny.
2. Custom layout for QFileDialog
Is it possible to just change the position of certain elements in the QFileDialog?
I'm in Linux and I want the "Open" button on the bottom right and the file extension on top.

QApplication::setFont

Keep in mind that on Windows and maybe on other OS, users can change font magnification at the OS level. On Windows, Qt abides by this, so a 10 pt font at 125% magnification is equivalent to a 12.5 pt font at 100%. I have seen this cause clipping and other layout issues if other widgets (like QLabel) have size constraints set which limit their expansion. If no constraints are set, then with magnification the widgets will expand to hold the full text.

On some OS, the OS native file dialog is used instead of a Qt-specific one, so it may not be possible to customize. You may be able to override this using QFileDialog::setOptions() before the dialog is shown on screen or derive a custom dialog from QFileDialog. To get to the individual widgets inside the Qt-based QFileDialog, you will need to call QFileDialog::layout() (inherited from QWidget) and then try to figure out which widget corresponds to the things you want to modify.
Sounds like more trouble than it is worth and a likely source of confusion to users who are used to seeing a particular style on their OS.
