Corner Widget Button is cut off?

[fvez_demtroys]

Hi,

I am trying to add a button as a corner widget on a QTabWidget.
I am able to add the button just fine but for some reason it isn't showing in its entirety.
Screenshot

Any idea why it is cut off?
As you can see in the image, the corner combo box isn't being cut off but the button is.
Here is the code used to display the corner button and corner combo box :

self.comboBox_cornerModule = QComboBox(self.centralWidget)
self.comboBox_cornerModule.setObjectName(u"comboBox_cornerModule")
self.comboBox_cornerModule.addItems(["Test", "Test"])
self.tabWidget.setCornerWidget(self.comboBox_cornerModule, Qt.Corner.TopLeftCorner)
self.comboBox_cornerModule.currentTextChanged.connect(self.toggleModule)

self.pushButton_testSoftware2 = QPushButton(self.centralWidget)
self.pushButton_testSoftware2.setObjectName(u"pushButton_testSoftware2")
self.pushButton_testSoftware2.setDefault(True)
self.pushButton_testSoftware2.setText('Test Software')
self.tabWidget.setCornerWidget(self.pushButton_testSoftware2, Qt.Corner.TopRightCorner)

Thanks!

Hi,

Which version of PyQt/PySide are you using ?
On which OS ?
Do you have a style sheet applied ?

[fvez_demtroys]

Hi SGaist,

This is with PyQt5 5.15.4.
macOS Catalina 10.15.7

No this is all without any style sheets.
We want the most native feel possible.

Thanks!

Can you provide a minimal script that allows to recreate that behaviour ?

[fvez_demtroys]

Hi SGaist,

I just wrote a script that would allow to recreate the behaviour as requested.
However, I seem to be unable to share it here. How could I send this over?

When dragging the file to the reply, I get
"

Thanks

Since the script is minimal, you can put its content directly in a post. Please use the </> button to format it properly.

Hi SGaist,

Here is the script.

Hope this helps find the issue.

Thanks!

The geometry of the corner widget will depend on the size hint of the widget and style as per the method documentation. There's likely something to search there.

Depending on what you want you can use a style sheet to influence the size of the corner widget.

[fvez_demtroys]

Hi SGaist,

Thanks for the suggestion, I'll have a look at the size hint.

As for the style sheet, I tried that but you instantly lose the native look of the UI, which we would like to avoid.

Thanks!
