Bug: Finding Fonts on Window Machines

[Jordan-Pierce]

For posterity:

It seems like on some Windows machines (specifically, NOAA), font folder's contents cannot be found, and TagLab.py cannot open properly. The issue has to do with finding the path to the folders? But, it works on most Window machines, so it's probably some default configuration on some machines with regards to paths. Below is the original code; although PATH_FONTS can be found by os.path.exists, the fond_idx is not coming back as a valid number <1, causing the script to not run.

Temporary fix is removing the if statements and just use Roboto by default.

    # set the application font
    if platform.system() != "Darwin":
        QFD = QFontDatabase()
        font_id1 = QFD.addApplicationFont(os.path.join(PATH_FONTS, "opensans/OpenSans-Regular.ttf"))
        if font_id1 == -1:
            print("Failed to load application font..")
            sys.exit(-2)

        font_id2 = QFD.addApplicationFont(os.path.join(PATH_FONTS, "roboto/Roboto-Light.ttf"))
        if font_id2 == -1:
            print("Failed to load application font..")
            sys.exit(-2)

        font_id3 = QFD.addApplicationFont(os.path.join(PATH_FONTS, "roboto/Roboto-Regular.ttf"))
        if font_id3 == -1:
            print("Failed to load application font..")
            sys.exit(-2)

        font = QFont('Roboto')
        app.setFont(font)
