In my sample application, I set a very simple stylesheet at the root level, which I expect to be applied to all widgets. However there is a file dialog under the print dialog that does not seem to be affected by the stylesheet at all.
1) Start the attached program.
2) Select Print from the File menu.
3) Click the tool button that allows you to select an output file.
4) A file dialog appears that has none of the expected attributes from the application's stylesheet.
Expected: A file dialog with colors set by stylesheet.
Actual: A native file dialog with no stylesheet attributes.
