We have a some problem with progress bar, because of such kind of progress bar as QProgressBar doesn't allow us to display progress in action with a unknown duration. Can you help us with search solution of this problem?
We have a problem with viewing media content from QWebView. If content is displayed by method QWebView.setUrl(QUrl(...)) when media is displayed correctly, but method setHtml(QString(...))don't display media. For example:
(with setHtml)
[code]
import sys
from PyQt4 import QtCore
from PyQt4 import QtGui
from PyQt4.QtWebKit import *
class ViewMessage(QtGui.QMainWindow):
def __init__(self, parent = None):
"""
initialization viewing window
@return
"""
super(ViewMessage, self).__init__(parent)
#connect plugins for video
QWebSettings.globalSettings().setAttribute(QWebSettings.PluginsEnabled,
True)
QWebSettings.globalSettings().setAttribute(QWebSettings.JavaEnabled,
True)
#our proxy(if it is needed)
#from PyQt4.QtNetwork import QNetworkProxy
#proxy = QNetworkProxy(QNetworkProxy.HttpProxy, "proxy.karelia.ru", 81)
#QNetworkProxy.setApplicationProxy(proxy)
self.view_mes_widget = QWebView()
text5 = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">\
<html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>\
<title>iframe</title><style type="text/css">HTML, BODY { background:transparent; padding:0; margin:0; border:0; overflow:hidden; }</style>\
</head><body><object style="height: 344px; width: 425px;"><param value="http://www.youtube.com/v/3eLKrECd4x8" name="movie" />\
<param value="true" name="allowFullScreen" /><param value="always" name="allowScriptAccess" />\
<embed height="344" width="425" allowfullscreen="true" type="application/x-shockwave-flash" src="http://www.youtube.com/v/3eLKrECd4x8">\
</embed></object></body></html>'
self.view_mes_widget.setHtml(text5)
self.view_mes_widget.show()
self.setCentralWidget(self.view_mes_widget)
self.show()
[/code]
(with setUrl)
[code]
import sys
from PyQt4 import QtCore
from PyQt4 import QtGui
from PyQt4.QtWebKit import *
class ViewMessage(QtGui.QMainWindow):
def __init__(self, parent = None):
"""
initialization viewing window
@return
"""
super(ViewMessage, self).__init__(parent)
#connect plugins for video
QWebSettings.globalSettings().setAttribute(QWebSettings.PluginsEnabled,
True)
QWebSettings.globalSettings().setAttribute(QWebSettings.JavaEnabled,
True)
#our proxy(if it is needed)
#from PyQt4.QtNetwork import QNetworkProxy
#proxy = QNetworkProxy(QNetworkProxy.HttpProxy, "proxy.karelia.ru", 81)
#QNetworkProxy.setApplicationProxy(proxy)
self.view_mes_widget = QWebView()
self.view_mes_widget.setUrl(QtCore.QUrl("embed.html"))
self.view_mes_widget.show()
self.setCentralWidget(self.view_mes_widget)
self.show()
[/code]
Only second example display media, though file "embed.html" contains the same html code.
P.S.:
Just in case this is a code from "main.py" file:
[code]
import sys
import os
def main():
"""
this function starts application
"""
from PyQt4 import QtGui
app = QtGui.QApplication(sys.argv) # Note: we can't draw dialog box in
from ViewMessage import ViewMessage
home_window = ViewMessage()
app.exec_()
sys.exit()
if __name__ == "__main__":
os.chdir(os.path.dirname(os.path.abspath(sys.argv[0])))
main()
[/code]
