[Kde-perl] driving the GUI

[Nick THOMPSON]

Hi,

So, perl and QT have proved extremely useful for writing apps driven by
the GUI. GUI actions can be easily linked to code using the signals and
slots. I have used this to write a wizard which gathers a whole bunch of
information from the user and validate it, but now I want close the
wizard and to go off and do something with the data, while proving a new
progress dialogue to keep the user up-to-data on progress. In this case
there are no GUI events, but my code goes off into the QT event loop
when I do "$app->exec;" and I can't do any processing.

So currently:

# run the wizard
my $wizard = CcmkbrWizard;
$app->setMainWidget($wizard);
$wizard->show;
$app->exec;

# open the progress dialogue
my $progress = Progress;
$app->setMainWidget($progress);
$progress->show;
$app->exec;

# do some processing while updating the progress dialogue...

Can somebody please give me a clue how to proceed (an example maybe)?
When the operation is complete and the progress bar gets to 100%, I will
need to enable the okay button (easy enough) and wait for it to be
clicked, so I will need to be in the event loop for that.

Many thanks,
Nick.
