How to Fix QStatusBar that stops to work if placed it in Layout?-CodePudding

I succeeded to moved the QStatusBar to a specific location (repositioning), but when I hover I don't see the tips anymore. I tried QStatusBar.show() or .setVisible(True) but doesn't still work. How would you approach this. Thanks

CodePudding user response：

The expected behavior of a status bar is to be shown on the bottom margin of the window, allowing temporary messages and also providing an internal layout for "extra widgets" displayed in it.

If you want to show the status tip somewhere else, then you probably don't need a QStatusBar at all, and a basic QLabel will suffice.

The only requirement is to override the event() function of the window and check for StatusTip events.

In the following example I assumed that you don't really need the default status bar (so you should remove it from Designer and update the generated uic file accordingly if you use that approach).

class Ui(QMainWindow):
    def __init__(self):
        super(Ui, self).__init__()
        uic.loadUi('Xuntitled.ui', self)
        self.fakeStatusBar = QLabel()
        self.gridLayout_status.addWidget(self.fakeStatusBar)
        
    def event(self, event):
        if event.type() == event.StatusTip:
            self.fakeStatusBar.setText(event.tip())
            return True
        return super().event(event)
