close widget within widget's constructor
Message 1 in thread
Hello All,
I'm new to Qt.
I'm trying to build a form / dialog that will close
immediately if the user doesn't have permission to
launch it. Here are my code :
Form::Form(....)
{
string permission;
permission=cApp->GetPermission(objectName().toStdString());
if (permission=="") destroy(TRUE);
}
I have put destroy(TRUE), but the form / dialog keep
showing (not closed immediately). Have tried to
replace destroy(TRUE) with close() and
done(QDialog::Accepted) / done(QDialog::Rejected) but
same result : the form is not closed immediately. Am I
missing something here ?. Is there something wrong
with my code / design ?.
Thanks in advance for your help,
regards,
si sol

Wouldn't it be easier to check for the permissions before launching the dialog
in the first place?

Actually the permission is not only applies to form
but to all individual object in the form. That's why
I put the permission check inside the object.

Why not add a "bool permission_to_launch()" method to the widget then
and call that before showing the widget?
anyways, i guess the best method to close a dialog is to call the quit()
slot.
Cheers,
Peter
