Non modal dialog : how?

[Yannick <ybarbeaux gmail com>]

Hello all,

I have been looking for a solution for many days but I am really stuck with
this very simple issue:

I want to display a MessageDialog saying only "Please wait" (no button)
while executing another command then automatically destroy this dialog when
the command has finished:

basically:

1-create and show messageDialog
2-do something else
3-hide or destroy messageDialog

Thus I want this MessageDialog NOT to be modal (otherwise it won't reach the
"do something else" before being closed).

The problem I face is the following:
- if I use waitingDialog->run(); then the dialog is modal (even if I set the
bool modal=false; at creation of the dialog)
- if I use waitingDialog->show() or showall(); then the dialog appears but
it is ALL BLANK, without any widget (the text I defined at creation of the
dialog or using the setMessage function does not appear). How strange!

I tried to call show() on the Box content_area of the dialog but that does
not work either.

Strangely, I cannot find much information about non modal dialogs on the web.

Any help would be greatly appreciated. Thanks!

Yannick.


here is the code with everything I tried, unsuccessfully:

Gtk::MessageDialog *waitingDialog = new Gtk::MessageDialog(*this, "Please
wait", false, Gtk::MESSAGE_INFO, Gtk::BUTTONS_NONE, false);
        
Gtk::Box *contentDialog = waitingDialog->get_content_area();
contentDialog->show_all();
waitingDialog->set_message("Please wait")
waitingDialog->activate();
waitingDialog->show(); 
waitingDialog->show_all(); 
waitingDialog->present();
//waitingDialog->run(); --> only for MODAL dialog (I think...)
        
doSomethingElse();
        
waitingDialog->hide();
delete(waitingDialog);
