Hide title/application bar in python Pyside6

poppypelt12

Hello, as the title suggests I am having trouble hiding the application(?) bar of a pop-up:
I tried using

self.setWindowFlag(Qt.FramelessWindowHint)

but it didn't work. Please help!!

@poppypelt12 Please show your code, for me it works

@jsulm Okay, here it is:

class LegendBar(QWidget):
    def __init__(self):
        super(LegendBar, self).__init__()
        self.setWindowFlag(Qt.FramelessWindowHint)
        self.setWindowFlags(Qt.WindowStaysOnTopHint | Qt.Tool)
        self.initUI()

    def initUI(self):
        self.setWindowTitle("LegendBar")
        self.setGeometry(1400, 0, 400, 1080)  # Set the dimensions of the LegendBar
        self.setWindowFlags(Qt.WindowType.WindowStaysOnTopHint)  # Ensure it's on top
        self.setStyleSheet("background-color:#3C413C;")

jsulm

@poppypelt12 Is LegendBar your main window (top level window)?

poppypelt12

@jsulm no, its a pop up window, i have another main window

If I change the order of these two lines it works for me

@jsulm I just tried that, it didnt disappear, however it changed the look of it:

It ruins the first one, use OR operator:
self.setWindowFlags(Qt.WindowType.WindowStaysOnTopHint or Qt.FramelessWindowHint)

@mpergand changed it to this, still doesn't work :(

class LegendBar(QWidget):
    def __init__(self):
        super(LegendBar, self).__init__()
        self.setWindowFlags(Qt.WindowStaysOnTopHint | Qt.Tool)
        self.setWindowFlag(Qt.FramelessWindowHint)
        self.initUI()

    def initUI(self):
        self.setWindowTitle("LegendBar")
        self.setGeometry(1400, 0, 400, 1080)  # Set the dimensions of the LegendBar
        self.setWindowFlags(Qt.WindowType.WindowStaysOnTopHint or Qt.FramelessWindowHint)  # Ensure it's on top
        self.setStyleSheet("background-color:#3C413C;")

@mpergand Alright, so, I changed it to this:

        self.setWindowFlags(Qt.WindowStaysOnTopHint | Qt.Tool | Qt.FramelessWindowHint)

However, it isnt 'clickable' anymore and the button inside it has completely disappeared...

You realize this undoes the work (Qt.Tool) in __init__(), right? Don't know if it makes a difference, but at least get something consistent.

P.S.
For now and the future, if you download https://doc.qt.io/qtforpython-6/overviews/qtwidgets-widgets-windowflags-example.html you can play with all the window flags to see all the effects you can get.

@JonB Yes, well, i removed that and now I'm getting this for some reason:

instead of this:

I just want the window frame to be hidden!

poppypelt12

@poppypelt12 Alright so. I changed the width of the pop-up to 880 instead of 1080 and it works now so, i guess its solved!

@poppypelt12
In your code you show nothing about adding any widgets onto the LegendBar. Did you put some layout on it? Maybe you just want left-aligned regardless of width?

P.S.
Can I buy toilet paper from your app? ;-)

@JonB Lol!! :-)) its an app for nursing homes
