python - PyQt application and infinite loop - 


  डीईफ़ मुख्य (): ऐप = QtGui.QApplication (sys.argv) GUI = GUIClass () gui.showUI () App.exec_ () जबकि true: if win32api.GetAsyncKeyState (win32con.VK_SHIFT): प्रिंट (True) अगर __name__ == '__main__': मुख्य ()

ऐप के बाद कोड Exec_ () चल नहीं रहा है अनगिनत लूप कैसे करें और मेरा पाय्युटी एप्लीकेशन चलाएं?

धन्यवाद।

pyqt अपने स्वयं के (अनन्त) ईवेंट लूप के साथ आता है ताकि आपको अपना खुद का निर्माण न करना पड़े। app.exec _ () इस पाश में प्रवेश करता है, यही कारण है कि आप निष्पादित करने के बाद कोड नहीं देखते हैं। QTimer के उपयोग का उदाहरण:

में मुख्य () से पहले exec_ ( ) : 

  def timout (): यदि win32api.GetAsyncKeyState (win32con.VK_SHIFT): प्रिंट (True) टाइमर = QtCore.QTimer (स्वयं) timer.timeout.connect (टाइमआउट ) टाइमर.प्रारंभ (100)

What I do is that I add the "default" option which is "nothing" Is set to. In the validity rules, I say this value is necessary. If the user does not choose any of the other options, the verification fails. $ op...
