Re: How to close FileChooserDialog immediately after selection of file?

["Milosz Derezynski" <internalerror gmail com>]

Not sure why you need the sleep() statement (i'm always somewhat suspicious about sleep()), but try this:

fcd1->hide();

while (Gtk::Main::pending())
   Gtk::Main::iteration();

I suspect that after hiding and before the sleep there is no time for Gtk+ to actually perform the hiding.

In my program a file gets chosen and then a routine taking this file as
parameter starts which takes some time.
My problem is: the FileChooserDialog closes only _after_ the routine has
finished.
I want the Dialog to be closed _before_ the routine starts.

I have tried it with FileChooserButton and with a separate Button which
calls a FileChooserDialog. For the last version I posted a Code Snippet. in
void on_button3_clicked() I would expect (and like to have) that

fcd1->hide(); //should close the dialog

works before the

sleep(3)-statement in switch(res),

however the hide() statement which should close the dialog comes into effect
after the sleep(3);
sleep(3); stands for the routine which takes some time.

do you have any suggestions?
