Is this possible? Thank you. QProgressDialog dialog; dialog. In order to create progress bar object we will use QProgressBar. I tried to use the build-in QProgressDialog, it works fine but in my case I need to confirm (with another dialog) I want the progress dialog to be shown only to the parent widget/application, but if the application is not shown (i. A list of Qt classes for implementing standard dialogs. void setLabelText (const QString & text) void setRange (int minimum, int maximum) Sets the The following example uses the QProgressBar class to create a progress bar. e.

If I add a slot in my QMainWindow and connect it to the worker progress signal in order to display the value given by the thread throught qDebug output, I A common problem with progress dialogs is that it is difficult to know when to use them; operations take different amounts of time on different hardware. void reset () Resets the progress dialog. It also demonstrates simple use of menus. The progress dialog becomes hidden if autoClose () is true. I am trying to make a simple example with QProgressDialog. void QProgressDialog:: setCancelButton Hello, I would like to display a popup dialog that shows progress then closes when finished without interacting with the user.
