[Qt-interest] the problem of QProgressDialog & QProgressBar

[Malyushytsky, Alex]

Why you don't use modal QProgressDialog dialog with setWindowModality(Qt::WindowModal), as in QT documentation?
http://doc.trolltech.com/4.3/qprogressdialog.html#details

According to my impression you should not have used show() and close() in modeless form. Just follow the example in documentation.

I'm sorry that I did not use plain text format.

Let me restate my question.

I have a code where call QProgressDialg as follows.

QProgressDialog progressDlg("Progress", "Cancel", 0, 100, this);

progressDlg.show(); //Calling this here only shows the title bar, no button and label. Why?
// progressDlg.exec(); Can not call this here, because the next step will never be executed.
// Unless there's a non blocking call to exec.

myFunction() ; // Do something here and show the result text to a dialogue

progressDlg->setValue(progressDlg->maximum());
progressDlg->close();

How can I make this progress dialog show itself completly without calling the exec()?
I read the document about progress bar and dialog,
and can not find out the answer.

Any idea?
Thank you.
