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?
