Is it possible to change/increase font size in system.file.openFile dialog?

On the touch screens with 1920x1080 resolution the directories are very small and it hard to select them with fingers…

Unfortunately, there’s no great way to adjust the size of the components - all the file dialogs in Ignition are instances of the [`JFileChooser`](https://docs.oracle.com/javase/7/docs/api/javax/swing/JFileChooser.html) class - and as you can see here, while it’s possible to drill into its components and adjust font sizing, it’s not a trivial thing to do: [https://stackoverflow.com/a/18771331](https://stackoverflow.com/a/18771331)

Complicating things further, all scripting events happen on the event dispatch thread, which is interrupted by any modal dialogs in Ignition - including the JFileChooser - so you won’t (easily) be able to access the file chooser through scripting.

This is what I came up with (in button actionPerformed event):

```auto

from javax.swing.filechooser import FileNameExtensionFilter

#start in this folder
chooser = JFileChooser("C:\\OMG\\BenderOne")
jezik =system.util.getLocale() 
#print "Language=", jezik

setFileChooserFont(chooser.getComponents())  

#Allow user to choose only folder
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY)
chooser.setAcceptAllFileFilterUsed(False)

chooser.addChoosableFileFilter(restrict)

if chooser.showOpenDialog(event.source.parent) == JFileChooser.APPROVE_OPTION:
	filepath = str(chooser.getSelectedFile())
