I tried GetOpenFileName function in another thread, and use g_main_loop_run() to refresh and block the main window, just as what Inkscape did.
The brief code is:
_main_loop = g_main_loop_new(g_main_context_default(), FALSE);
if (GThread *td = g_thread_create(file_selector_thread, NULL, TRUE, NULL)) {
g_main_loop_run(_main_loop);
}
The thread function 'file_selector_thread' would invoke GetOpenFileName function to open a windows style file selection window, and when file selected, 'file_selector_thread' thread would call 'g_main_loop_quit(_main_loop)' before quit, so 'g_main_loop_run(_main_loop)' function would return.
The problem is: using this method, I cannot block the main window and making the file selection window modally. The reason is g_main_loop_run(_main_loop) function seems to accept and handle signals from main window as well. So the main window can still operate.
Any suggestions?
