PyQt5 - Hide window's title bar without hiding frame

Question

I'm developping a text editor with PyQt5 and I want to create my own "title bar". I've created my own title bar and I have something just like the image above. The only problem is the window's frame. So far I've been using:

setWindowFlags(Qt.FramelessWindowHint) 

But I just realised that with this flag there is no frame (cause it's "Frameless") and without the frame I can't resize my window by dragging the border.

I've tried CustomizeWindowHint flag but the title bar is still there, just without icon, name and buttons.

A temporary solution is to detect whenenver the mouse enter the window by installing eventFilter, get its positions, if it's on the border then we have to change the cursor icon (up, left, down, left-up, left-down,...) and if the user drags then calculate and resize window.

Another solution is to set 8 QSizegrip at every corner of the window but we will have to somehow hide those grips and make sure that they don't take any space because we will add 3 grips at the TOP of the title bar so it will be ugly.

But I don't really like these solutions. So is there anyway that I can hide the title bar and keep the frame?

Answer 1

I'm on Windows 10, and it works fine Only the title bar is removed and the frame is maintained

self.setWindowFlags(Qt.Window | Qt.CustomizeWindowHint | Qt.WindowStaysOnTopHint)
