问题 I'm trying to make a QLabel not visible by default in Qt Designer. I can hard code it but I was wondering if there was a way to set this using the designer. m_uiForm.aLabel->setVisible(false); 回答1: As far as I know, this is not possible from QtDesigner.

问题 I'm using Qt to make a gui application for my beagleboard. I'm trying to make a QLabel blink with a custom image.
