setting QMessage IconPixmap to the PyQt built-in icons

[explorer100]

Hello.

In trying to set the icon of the QMessage dialog to one of the PyQt6 builtin icons using:

apply_pixmap = getattr(QStyle.StandardPixmap, "SP_DialogApplyButton")
apply_icon = self.style().standardIcon(apply_pixmap)

I get,
TypeError: setIcon(self, a0: QMessageBox.Icon): argument 1 has unexpected type 'QIcon'

Trying the setIconPixmap using:

apply_pixmap = getattr(QStyle.StandardPixmap, "SP_DialogApplyButton")
self.message.setIconPixmap(apply_pixmap)

I get,
TypeError: setIconPixmap(self, a0: QPixmap): argument 1 has unexpected type 'StandardPixmap'

Any suggestion to address this?

@explorer100 setIcon does not accept a QIcon, please read documentation: https://doc.qt.io/qt-6/qmessagebox.html#icon-prop

https://doc.qt.io/qt-6/qmessagebox.html#iconPixmap-prop accepts QPixmap as you can see in documentation (https://doc.qt.io/qt-6/qmessagebox.html#iconPixmap-prop). You are passing a StandardPixmap. Create a QPixmap and pass it to setIconPixmap.

QPixmap

thank you, but if I am interested in one of the built-in icons provided by PyQt, is there a way to convert them to QPixmap?

Hi,

You have to do it in two steps:

• get the standard icon using QStyle::standardIcon
• get the pixmap from the icon using one of the QIcon::pixmap overload

Thank you .. this worked really well:

    apply_pixmap = getattr(QStyle.StandardPixmap, "SP_DialogApplyButton")
    apply_icon = self.style().standardIcon(apply_pixmap)
    q_pixmap = apply_icon.pixmap(apply_pixmap)
    self.message.setIconPixmap(q_pixmap)

Out of curiosity, why are you using getattr ?

I have no specific reason to use getattr...
My objective is just to show this built-in icon in QMessage.
Is there a more straightforward way of doing it?

QStyle.StandardPixmap.SP_DialogApplyButton (PySide6/PyQt6) should work for this. (Or probably QStyle.SP_DialogApplyButton if PySide2/PyQt5.)

[explorer100]

Thank you.. that worked for PyQt6

QStyle.StandardPixmap.SP_DialogApplyButton

@SGaist

Just to complete the discussion, is there a simpler way to do this than:

apply_pixmap = QStyle.StandardPixmap.SP_DialogApplyButton
apply_icon = self.style().standardIcon(apply_pixmap)
q_pixmap = apply_icon.pixmap(apply_pixmap)

Thank you all for the advice.

[SGaist]

apply_icon = self.style().standardIcon(QStyle.StandardPixmap.SP_DialogApplyButton)
q_pixmap = apply_icon.pixmap(QStyle.StandardPixmap.SP_DialogApplyButton)

[explorer100]

@SGaist

That won't work because you don't have apply_pixmap anymore to use.

I think you meat this:

apply_icon = self.style().standardIcon(QStyle.StandardPixmap.SP_DialogApplyButton)
q_pixmap = apply_icon.pixmap(QStyle.StandardPixmap.SP_DialogApplyButton)

[SGaist]

@explorer100 Indeed, and fixed.
