Dynamically creating GUIs on the same window

[Flurite]

I am trying to dynamically instance new GUIs on to the current widget window. I tried doing this:

@QLabel* newLabel = new QLabel("Hello");
newLabel->show()@

but that creates a new window with that widget.

Is it possible to dynamically create widgets on the same window?

You'll need to set the parent to the respective window. I.e. use the constructor that takes the label string as first and the parent QWidget as second argument.

Would I set the parent to the centralWidget in order for the widget to appear on the same window? That's the default object I believe.

Yes, for example.

Also, check out QLayout to control how you arrange your new widgets. Use centralWindow->setLayout() first, and then you can dynamically call addWidget() on the layout.

I'd start with "QVBoxLayout":http://qt-project.org/doc/qt-4.8/qvboxlayout.html or "QHBoxLayout":http://qt-project.org/doc/qt-4.8/qhboxlayout.html (vertical or horizontal boxes), and move on to more advanced layouts after that.
