How to show and hide QtGui.QGridLayout in PySide - python-2.7

Question

Here I am creating a layout called _grid and putting few labels and slider in the layout .
Now I want this layout to be hide first then onclick I want to show it .
If there is any simple function associated with QtGui.QGridLayout to show and hide.
I googled and found this is available for QWidget by QWidget.hide()
class TimeSlider (QtGui.QVBoxLayout):
def __init__ (self):
QtGui.QVBoxLayout.__init__ (self)
# Put everything in a grid
_grid = QtGui.QGridLayout ()
self.addLayout (_grid)
# Slider limit labels
_grid.addWidget (QtGui.QLabel (''), 0, 0)
_labelLayout = QtGui.QHBoxLayout ()
_grid.addLayout (_labelLayout, 0, 1)
self.lower = QtGui.QLabel ('LOW')
_labelLayout.addWidget (self.lower)
self.higher = QtGui.QLabel ('HIGH')
self.higher.setAlignment (QtCore.Qt.AlignRight | QtCore.Qt.AlignVCenter)
_labelLayout.addWidget (self.higher)
# Slider
_grid.addWidget (QtGui.QLabel (''), 1, 0)
self.sliderBarLayout = QtGui.QHBoxLayout ()
self.sliderBarLayout.setSpacing (0)
_grid.addLayout (self.sliderBarLayout, 1, 1)
self.sliderBarLayout.addWidget (self.leftEndstop)
self.slider = QtGui.QSlider (QtCore.Qt.Horizontal)
self.slider.setTickPosition (QtGui.QSlider.TicksBelow)
self.slider.setTracking (True)
self.slider.setMinimumWidth (40)
self.slider.setPageStep (1)
self.sliderBarLayout.addWidget (self.slider)
self.rightEndstop = RightEndstop (self, self.root)
self.sliderBarLayout.addWidget (self.rightEndstop)

import sys, time
from PyQt4 import QtGui, QtCore
class TimeSlider (QtGui.QVBoxLayout):
def __init__ (self):
QtGui.QVBoxLayout.__init__ (self)
# Put everything in a grid
_manLayout = QtGui.QVBoxLayout ()
self._frame = QtGui.QFrame();
_manLayout.addWidget(self._frame)
_grid = QtGui.QGridLayout (self._frame)
# Slider limit labels
_grid.addWidget (QtGui.QLabel (''), 0, 0)
_labelLayout = QtGui.QHBoxLayout ()
_grid.addLayout (_labelLayout, 0, 1)
self.lower = QtGui.QLabel ('LOW')
_labelLayout.addWidget (self.lower)
self.higher = QtGui.QLabel ('HIGH')
self.higher.setAlignment (QtCore.Qt.AlignRight | QtCore.Qt.AlignVCenter)
_labelLayout.addWidget (self.higher)
# Slider
_grid.addWidget (QtGui.QLabel (''), 1, 0)
self.sliderBarLayout = QtGui.QHBoxLayout ()
self.sliderBarLayout.setSpacing (0)
_grid.addLayout (self.sliderBarLayout, 1, 1)
# self.sliderBarLayout.addWidget (self.leftEndstop)
self.slider = QtGui.QSlider (QtCore.Qt.Horizontal)
self.slider.setTickPosition (QtGui.QSlider.TicksBelow)
self.slider.setTracking (True)
self.slider.setMinimumWidth (40)
self.slider.setPageStep (1)
self.sliderBarLayout.addWidget (self.slider)
self._frame.setLayout(_grid)
self.addLayout (_manLayout)
#self.rightEndstop = RightEndstop (self, self.root)
# self.sliderBarLayout.addWidget (self.rightEndstop)
def show(self):
self._frame.show()
def hide(self):
self._frame.hide()
def isHidden(self):
return self._frame.isHidden()
class NewTimeSliderTest(QtGui.QWidget):
def __init__(self, parent=None, total=20):
super(NewTimeSliderTest, self).__init__(parent)
self.newTimeSlider = TimeSlider()
self.resize(841, 474)
self.newTimeSlider.hide()
self.button = QtGui.QPushButton('Show/Hide')
self.button.clicked.connect(self.handleButton)
main_layout = QtGui.QGridLayout()
main_layout.addWidget(self.button, 0, 0)
main_layout.addLayout(self.newTimeSlider, 0, 1)
self.setLayout(main_layout)
self.setWindowTitle('Test')
self._active = False
def handleButton(self):
#self.newTimeSlider.show()
isHidden = self.newTimeSlider.isHidden()
if isHidden:
self.newTimeSlider.show()
else:
self.newTimeSlider.hide()
app = QtGui.QApplication(sys.argv)
bar = NewTimeSliderTest(total=101)
bar.show()
sys.exit(app.exec_())
How about this ?
Any time you can all like this.
self.newTimeSlider.show()
or
self.newTimeSlider.hide()
