Wrong font used for file chooser

What happened

The new feature to allow customizing FlatLaf is nice, but when changing the font and changing the font size the new font is not used for file chooser file list and details views.

How to reproduce

1. Choose Tools > Options > Appearance > FlatLaf
2. In the Advanced section, click the Edit custom properties button
3. Close the options dialog and add a line to FlatLaf.properties (which should now be open in the editor) to change the default font (e.g. defaultFont = "Nanum Brush Script")
4. Save the file and close NetBeans
5. Launch NetBeans again with a custom font size (e.g. ./bin/netbeans --fontsize 24). You'll see the UI has changed to use the new font as expected
6. Choose File > Open File...

The file chooser dialog that appears uses the selected font for most of the UI, but the file list and detail views use the standard sans serif font rather than the new font.

If you launch NetBeans without overriding the font size, the file chooser uses the correct font.

Did this work correctly in an earlier version?

No / Don't know

Anything else

I suspect this is due to the logic in AllLFCustoms.initCustomFontSize where it resizes the existing font for "FileChooser.listFont" (and others). The problem is that at this point there is no value set for some of the settings including "FileChooser.listFont", "OptionPane.messageFont", and "windowTitleFont" and they are then assigned the default Dialog font.

Some possible solutions:

1. If the setting doesn't yet exist, don't set it since "FileChooser.listFont" falls back to "List.font", "OptionPane.messageFont" falls back to "Label.font". "windowTitleFont" may need separate handling since it seems to fallback to a hard coded value where used, so perhaps it should fallback to another existing UIManager value instead?
2. Set the default values from FlatLaf settings, either "defaultFont" or "monospaced.font" and only fallback to the hard coded values if those don't exist

More a workaround, but have you tried setting the font size in the FlatLaf defaultFont property too?

[rkeen-siemens]

Yes, setting the font size in the defaultFont property doesn't make a difference. The font is still set to dialog.

@rkeen-siemens did you remove the --fontsize argument in the process? Setting the defaultFont to eg. 20 FONT_NAME works for me. At least in the file chooser.

Good point. Removing the --fontsize argument does work around the issue.
