how to selectall text inside an editable QComboBox (pyqt or pyside)

adfinem_rising

I am trying to create a combobox that has font sizes in it. similar to microsoft word fontsize combobox.
i just would like to know, how do you select all the text inside an editable combobox when the user clicks on it?

this does not seem to work:
self.font_size_combo_box.lineEdit().selectAll

and also this:
self.font_size_combo_box.lineEdit().setCursorPosition(0)

thanks in advance. i really have no idea how to have the text in the comboBox be selected whenever user clicks in the comboBox.

def prevent_null_entry(self):
        any_unique_value = 1
        validation_rule = QDoubleValidator(1,99,0)
       print(validation_rule.validate(self.font_size_combo_box.currentText(),any_unique_value))

        if validation_rule.validate(self.font_size_combo_box.currentText(), any_unique_value)[0] == QValidator.Acceptable:
            self.font_size_combo_box.lineEdit().setCursorPosition(0)
        else:
            # message box warning
            qtw.QMessageBox.warning(self,"Can't leave this input field blank","Please type-in your desired font size between [1 to 99]",qtw.QMessageBox.StandardButton.Ok)
            self.font_size_combo_box.lineEdit().selectAll
            self.font_size_combo_box.setCurrentText(str(13))

I don't know about your whole question [actually this might be the answer], but since that's a function call you need to add the ()....

@JonB OMG!!! hahaha that was the answer all along?! i was sitting here wondering why it was not working!! thanks!!

@adfinem_rising
Does Python not warn you about accidentally using a function on a statement of its own without the ()s? Else it's going to be a pretty common gotcha....

@JonB not really, im using visual studio code and it does not say anything to me. it just doesn't give an error and the application does not crash. so i couldn't understand what was happening. thanks again for the answer, i spent the wholeday googling. who knows maybe i would have been googling for a month and still not get a solution lol

i got that selectall code from stackoverflow and it didnt have the () at the end
