How can one have two or more active windows at the same time?

[bask185]

I have a small obstacle with my GUI application. I need to be able to use the pushbuttons of 2 separate windows at the same time.

That bottem bar is my toolbar. It is a separate window which I can open from the mainwindow.

Clicking on one of the toolbar's pushbuttons emits a signal to the mainwindow which opens one of the following windows; Help, maintenance, Details, SSP........ Database.

When one of the 'new' windows is open, I cannot use the buttons of the toolbar anymore. The idea is that if I open lets say the 'Help' window and I click on the 'SSP' button on the toolbar, the 'Help' window closes and the 'SSP' window opens.

Right now I have to manually close the 'new' window before I can use the Toolbar again. I have tried 2 ways of opening the windows but so far I have had no luck :/

Way 1:

help->setModal(true);
help->setGeometry(0,0,1024,668);
help->exec();

Way 2:

login = new Login(this);
login->setGeometry(0,0,1024,668);
login->exec();

Way 1 has as drawback that only the last-launched window is active and thus useable

Way 2 has more drawbacks. In case when I use it with the toolbar the signals become inactive so the pushbuttons don't do a thing. In case I use this way for any of the other windows, the toolbar becomes hidden as long as the other window is active. When I manually close the window the toolbar re-appears.

I tried every combination but no luck.

Which Magic Qt feature can make this obstacle go away?

You should not set modal to true and you should use show() instead of exec(). exec() is a blocking call - the caller will be blocked until the new window was closed. Modal windows/dialogs block other windows/dialogs until they are closed. See http://doc.qt.io/qt-5.9/qdialog.html

This works ;)

Hi,

What about using a QStackedWidget and switch between the widgets you want to show ?

I'll read it for usage in the feature. For now Jsulms simple solution suffices.
