PyQt QWebView in QTabWidget

[ete]

Hello!

I have a question, I want to display a PDF in one tab of my QTabWidget. Is this possible?

If I try


import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtWebKit import *

app = QApplication(sys.argv)
web = QWebView()
web.settings().setAttribute(QWebSettings.PluginsEn abled, True)
web.show()
web.load(QUrl('test.pdf')) # Change path to actual file.
sys.exit(app.exec_())

everything works as expected.

If I add a QWebView to a tab, the PDF is not displayed:


from PyQt4 import QtGui
from PyQt4 import QtCore
from PyQt4.QtWebKit import*
import sys



def main():

app = QtGui.QApplication(sys.argv)
tabs = QtGui.QTabWidget()
pushButton1 = QtGui.QPushButton("QPushButton 1")
pushButton2 = QtGui.QPushButton("QPushButton 2")

web = QWebView()

web.settings().setAttribute(QWebSettings.PluginsEn abled, True)

web.load(QtCore.QUrl('file:///test.pdf'))

tab1 = QtGui.QWidget()
tab2 = QtGui.QWidget()
tab3 = QtGui.QWidget()

vBoxlayout = QtGui.QVBoxLayout()

#vBoxlayout.addWidget(pushButton2)
vBoxlayout.addWidget(web)
vBoxlayout.addWidget(pushButton1)

#Resize width and height
tabs.resize(250, 150)

#Move QTabWidget to x:300,y:300
tabs.move(300, 300)

#Set Layout for Third Tab Page
tab1.setLayout(vBoxlayout)

tabs.addTab(tab1,"Tab 1")
tabs.addTab(tab2,"Tab 2")
tabs.addTab(tab3,"Tab 3")

tabs.setWindowTitle('PyQt QTabWidget Add Tabs and Widgets Inside Tab')
tabs.show()

sys.exit(app.exec_())


if __name__ == '__main__':
main()

Can anybody tell me what I am doing wrong?
Thanks in advance!
