[ PyQt ] Button Widget

1. QPushButton

def __init__(self):
    QWidget.__init__(self, flags=Qt.Widget)
 
    self.btn_push = QPushButton()
    self.edt_number = QLineEdit()
 
    self.layout = QBoxLayout(QBoxLayout.TopToBottom, self)
    self.setLayout(self.layout)
    self.init_widget()

1) Signals

• clicked(bool)
• pressed
• released
• toggled(bool)

def init_widget(self):
   self.setWindowTitle("QPushButton Shortcut")
    self.click_cnt = 0
    self.edt_number.setText(str(self.click_cnt))
    self.layout.addWidget(self.edt_number)
 
    self.btn_push.setText("더하기 단축키(Alt + F7)")
    self.btn_push.pressed.connect(self.buttonClicked)
    self.btn_push.setShortcut("Alt+F7")
    self.layout.addWidget(self.btn_push)
        
def buttonClicked(self):
    self.click_cnt += 1
    self.edt_number.setText(str(self.click_cnt))

2) Shortcut 설정 (단축키)
