New window open from a click of a button (Cmake)

[Rashed]

Hi all.

I'm very new to this. I'm making a GUI using Cmake.
I need to open one window with click of a button. Very silly but my apologies as a beginner.

Kindly help me how to open a new window (which is again editable) from a click of a button.

Thanks for your kindness.

Kind regards,
Rashed.

cmake is not relevant. That is just for building your project.

Start by reading Signals & Slots, you need to understand this concept before you can achieve anything in Qt.

Then connect() your QPushButton::clicked signal to a slot you write, or an inbuilt slot on a Qt widget, which opens a new window, e.g. some kind of QWidget::show().

a new window (which is again editable)

"Windows" are not "editable". Depends what you really mean here.
