win32: FileChooserWidget + gtk_window_set_deletable

Hi, could anyone please say if this should be considered a bug -- if so, I'd file an issue at bugzilla: * use win32 (not yet tested on linux) * create toplevel window * gtk_window_set_deletable(window,FALSE) [this is the critical part] * place a FileChooserWidget into window * show window * click

hi, what does "temporarily" mean here: gdk_threads_set_lock_functions: "[...] When GTK+ unlocks the GTK+ lock when entering a recursive main loop, the application must temporarily release its lock as well." Does that mean (A) that GTK+ sometimes simply tells me that it has done its tasks and I c
