The online installer provides 5.15.2. It also provides a more recent version of Qt Creator which might work better than the one you are currently using.

Well, huh. I thought I tried that one with the bigger project before, but it does work with the test program here, so that must have been something else. Thank you for your assistance.

@elfring Hi I am curious on how the clarification will evolve Me too. As what you wish for - takes a huge amount of code and forces a preconceived structure on the users and its going from very complicated and involving to plain impossible in scope :) In 30 years of programming, i have not seen any WYSIWYG editor that supported adding unknown classes to static code generation for GUI instance construction.

Just realized, that I had still thread still open. I'll share how I managed to circumvent the problem. Sadly I haven't found a real solution as of now. In the function that makes the screenshot, I added this line just before calling QWidget::render this->setStyleSheet("cStackedWidget {background-color:white;}" "QWidget#LiveStatus{background-color:white;}" ... //List of all QStackedwidget Pages ... "QWidget#FanThreshhold{background-color:white;}"); For some reason I have to set the stylesheet new for each time. Simply setting this once will not work. Anyway, I'll mark it as solved, unless someone else has a new idea !?

Thanks for the link, but I am mostly interested in being able to do it all through the Qt Designer UI via a plugin.

@bigThrum Hi, wid->setLayout(layout); wid2->setLayout(layout); This will not work. You need to have a separate layout object for each of your widgets, and a separate set of QPushButton objects for each of the layouts. Kind regards.
