Hi,
I have a short program (below) that displays two windows, each with a
button. Clicking the button pops up a modal dialog (in this case a file
chooser, but the type of the dialog does not really matter).
I would like the two windows to be completely independent, i.e. clicking
the button in one window should not disable the other window and vice-versa.
I realize this can probably be done by avoiding gtk_dialog_run and
handling the window interactions from the main loop, but that would make
the development very tedious.
Obviously, if I wanted to nest main loops for two independent windows, I
would have to run each window in its own thread. However, it seems that
gtk_main can't be run from several threads at once.
So is there a way to accomplish the above without sacrificing the
simplicity of gtk_dialog_run?
Thank you in advance.

gtk_button_set_label(GTK_BUTTON(button), "show dialog");

gtk_widget_show(window);
}
int main(int argc, char *argv[])
{
gtk_init (&argc, &argv);
GtkWidget * wnd1 = create_window();
GtkWidget * wnd2 = create_window();
gtk_main();
}
