I'm adapting a Linux program to run under Windows, using gtk-win32. The app has a particular dialog box which displays a Gtk::FileChooserButton. When the dialog first gets displayed, there's no particular file selected and the button's entry says "(None)". Clicking the button launches a Gtk::FileChooser and the chosen file then gets "remembered" by the button. In other words, next time the main dialog box gets displayed, the last file to be chosen is effectively pre-selected into the FileChooserButton. This seems to be achieved by calling Gtk::FileChooser::set_filename()
All the above works fine. But under certain circumstances I don't want any file to be preselected. Even if the dialog has been shown before I want the FileChooserButton to say "(None)" when it's next displayed (like it did the first time around). I assumed that I might be able to achieve this by calling Gtk::FileChooser::set_filename() with an empty string. And indeed that does seem to work when I build under Linux. But it doesn't work for me if I compile for Windows and link to gtk-win32. Passing an empty string seems to do some strange things. Firstly, it bizarrely selects whichever folder the main app is running in. Secondly, if I press the button to display the FileChooser, the FileChooser won't respond to mouse clicks (although it continues responding to mouseover events). If all else fails I guess I could delete the FileChooserButton object and create a new one each time. But before I consider that option I just wondered if I'm doing something obviously wrong. Is there an actual recommended way of removing a file that's currently in the FileChooserButton's memory? (i.e. resetting its entry back to "(None)".
