Is there a way to add multiple filemasks in wx.lib.filebrowsebutton.FileBrowseButton?

Question

I'm trying to make a wx.lib.filebrowsebutton.FileBrowseButton button match both txt and csv files, but it doesn't seem to support glob pattern as described, *.{txt,csv} ends up matching nothing on windows and it literally tries to look for files with extension of {txt,csv}.

So how do I make it work for both txt and csv files?

Answer 1

The documentation is not very clear. You should be using a semi-colon inside parenthesis, like so: "TXT and CSV files (*.txt; *.csv)|*.txt; *.csv"

You can also add a second line like so: "TXT and CSV files (*.txt; *.csv)|*.txt; *.csv|PNG files (*.png)|*.png"
