hi all,
i rewriting code for my filebrowser to GIO.
Functionality is perfect for my program.
But i want monitoring some changes in actual dir.
( for update etc.)
i know its gioFile.monitor_directory() but i never user
gobject too much.
seems that event catching for gio.File dont work in gtk.main() loop.
after googling i know i must use gobject.MainLoop().run() instead.
after rewrite my gtk.main() loop into gobject.MainLoop() monitoring
still dont work :(
Please kick me to the right way.
i have main program in gtk.main() loop.
this program have 'million :)' gui widgets.
from this program i importing FileBrowser module
and adding it into notebook.
Please help me get monitoring working.
PS : any comments for make this example better are welcome thanks.
BTW: sry for my horible english.
.. MAIN program snippet :)
......
......
import FileBrowser
self.__browser = FileBrowser.FileBrowser()
self.__plug.append_page(self.__browser, Label('FileBrowser'))
......
......
if __name__ == '__main__':
APP = MyApp()
gtk.main()
'''
from gobject import MainLoop
MainLoop().run()

.. END of Main program
here is FileBrowser module:
