pyqt清除所有控件PyQt5 QTableWidget 删除所有行:

PyQt5 QTableWidget 删除所有行:

self.tableWidget.setRowCount(0)

self.tableWidget.clearContents()

 删除layout中的所有widget：

      for i in range(self.gridLayout.count()):
       self.gridLayout.itemAt(i).widget().deleteLater()
  
 

加判断：

      import sip
      ...
      class Window(QtGui.QMainWindow):
       ...
      def populateFrame(self):
       self.deleteLayout(self.frame.layout())
       layout = QtGui.QVBoxLayout(self.frame)
       ...
      def deleteLayout(self, layout):
      if layout is not None:
      while layout.count():
       item = layout.takeAt(0)
       widget = item.widget()
      if widget is not None:
       widget.deleteLater()
      else:
       self.deleteLayout(item.layout())
       sip.delete(layout)
