change the default display message of QKeySequenceEdit?

Question

when adding a QKeySequenceEdit, theres this default display message "Press shortcut". is there any way to change or delete it? i tried to look for here (https://doc.qt.io/qt-6/qkeysequenceedit-members.html) but it doesnt seem to provide any options for it.

I had this same problem and found a way to deal with it after reading the answer from @SebDieBln. I am not a programmer, so this is probably not the most elegant solution but it worked for my needs, at least.

I have a separate settings class where I handle changing hotkeys, so I applied Sebs suggestion where I added the QKeySequenceEdit:

self.hotkey_edit = QKeySequenceEdit(self)
line_edit = self.hotkey_edit.findChild(QLineEdit, "qt_keysequenceedit_lineedit")
    if line_edit:
        line_edit.setPlaceholderText("Enter custom Placeholdertext here")

I was already using an eventFilter to intercept other events, so I installed it on the settings class upon creation in my main window class:

self.settings_dialog.installEventFilter(self)

and made it listen for changes on the QKeySequenceEdit, and if the text is cleared, reset the placeholder text:

def eventFilter(self, obj, event):
    if hasattr(self, 'settings_dialog') and self.settings_dialog:
        if obj == self.settings_dialog.hotkey_edit and event.type() == QEvent.Type.KeyRelease:
            line_edit = self.settings_dialog.hotkey_edit.findChild(QLineEdit, "qt_keysequenceedit_lineedit")
            if line_edit and not line_edit.text():
                line_edit.setPlaceholderText("Enter custom Placeholdertext here")

    return super().eventFilter(obj, event)
