The following is a basic working example of what I think you're trying to do. It also hides the lower controls (sliders and buttons) in full screen mode like a media player would (just delete line 55 to prevent this):
@
from PyQt4.QtCore import *
from PyQt4.QtGui import *
class BlackWidget(QWidget):
doubleClick=pyqtSignal()
def __init__(self, parent=None, **kwargs):
QWidget.__init__(self, parent, **kwargs)
def paintEvent(self, e):
p=QPainter(self)
p.fillRect(self.rect(), Qt.black)
def mouseDoubleClickEvent(self, e):
self.doubleClick.emit()
class Widget(QWidget):
def init(self, parent=None):
QWidget.init(self, parent)
self.resize(640,480)
self._fullScreen=False
l=QGridLayout(self)
blackWidget=BlackWidget(self, doubleClick=self.changeScreenSize)
l.addWidget(blackWidget, 0, 0, 1, 4)
self._controls=[]
slider1=QSlider(Qt.Horizontal, self)
self._controls.append(slider1)
l.addWidget(slider1, 1, 0, 1, 4)
button1=QPushButton("Button 1", self)
self._controls.append(button1)
l.addWidget(button1, 2, 0)
button2=QPushButton("Button 2", self)
self._controls.append(button2)
l.addWidget(button2, 2, 1)
button3=QPushButton("Button 3", self)
self._controls.append(button3)
l.addWidget(button3, 2, 2)
slider2=QSlider(Qt.Horizontal, self)
self._controls.append(slider2)
l.addWidget(slider2, 2, 3)
@pyqtSlot()
def changeScreenSize(self):
self.showNormal() if self._fullScreen else self.showFullScreen()
for c in self._controls: c.setVisible(self._fullScreen)
self._fullScreen^=True
if name=="main":
from sys import argv, exit
a=QApplication(argv)
w=Widget()
w.show()
w.raise_()
exit(a.exec_())

Hope this helps ;o)
