c++ - How to wait for GTK+ object to be destroyed before continuing? -

i have program open file dialog , take file name , resource intensive operations.

my problem while opertion running, though gtk_widget_destroy() has been called on file dialog stays open.

this problem because need implement loading bar in near future , don't want dialog hanging around. code looks this:

if(gtk_dialog_run(gtk_dialog(fileselect)) == gtk_response_ok){     filename = string(gtk_file_chooser_get_filename(gtk_file_chooser(fileselect)));     gtk_widget_destroy(fileselect); }else{     gtk_widget_destroy(fileselect);     return;                        }  resourceintensivefunction(); 

so how can wait file dialog exit before continuing?

btw i'm using gtk 2.

so, found out how it, relatively simple.

while(gtk_events_pending()){     gtk_main_iteration_do(true); } 

hope helped someone.
