Do you know how to hide minimize, maximize and close buttons of title bar in Qt. I especially need to hide it on QMainWindow.
To turn off the Maximize Button on the default windows, set the max size of your Window on your Ui file. You will notice the Maximize button is greyed out when you run your program.
What is the collective name given to Minimize, Maximize and close buttons of a window? → Minimize and Maximize buttons are also called Control Buttons appear at the top right corner of any Application window or Word.
Set this window flags Qt::Window | Qt::WindowTitleHint | Qt::CustomizeWindowHint
Note, that on some platforms it behaves in different way. For example on Mac OS X it Disables, (not hides) close/minimize/maximize buttons
If you are using Qt qml then, to remove minimize, maximize and close button, set the frameless window flag in the window function in your main.qml file, like below:
flags: Qt.FramelessWindowHint
