[PyQt] QLabel is visible but isVisible() is always false

[Katja Wegner]

sorry, didn't know that.

import sys
from PyQt4.QtGui import *


class Window(QMainWindow):

    def __init__(self, parent):
        QMainWindow.__init__(self)

        gen = General(self)
        gen.addLabel()
        gen.update(1)
        gen.show()

class General(QDialog):
  
    def __init__(self, parent):
        QDialog.__init__(self, parent)
        self.layout = QVBoxLayout(self)
        self.layout.setMargin(20)
        self.addLabel()
    print "vis=", self.label.isVisible()
   
    def addLabel(self):
        self.label = QLabel("Arc types in the module:")
        self.label.setVisible(0)
    print  "vis=", sself.label.isVisible()
        self.layout.addWidget(self.label)
      
    def update(self, isInModule):
        if isInModule:
          self.label.show()
      print "vis=", s self.label.isVisible()


def main():
    application = QApplication(sys.argv)
    nbWindow = Window(application)
    application.setActiveWindow(nbWindow)
    nbWindow.resize(100, 100)
    nbWindow.show()
    sys.exit(application.exec_())
   
if __name__ == "__main__":
    main()
