I have trayicon on Qdialog, also I have a webview on Qmainwindow. I want to do that a web page run like tray. The codes run perfectly but i have a problem with the window size. when I maximize the page on tray, the web page is smaller than qwidget.

Qt Code: 
  1. //main.cpp
  2. #include "window.h"  //the object inherited by Qdialog
  3. #include "mainwindow.h" //the object inherited by Qmainwindow
  4.  
  5. int main(int argc, char *argv[])
  6. {
  7.  QApplication app(argc, argv);
  8.     Window box;
  9.     MainWindow window;
  10.     window.setParent(&box);
  11.  
  12.     return app.exec();
  13. }
  14.  
  15. //window.cpp
  16. Window::Window()
  17. {
  18.     createActions();
  19.     createTrayIcon();
  20.     setIcon();
  21. /*..*/
  22.  
  23.     trayIcon->show();
  24.     setWindowTitle(tr("Blog Search"));
  25.     resize(600, 600);
  26. }
  27. MainWindow::MainWindow()
  28. {
  29.     QTime time = QTime::currentTime();
  30.     qsrand((uint)time.msec());
  31.     int randomValue = qrand() % 999;
  32.     view = new QWebView(this);
  33.  
  34.     QUrl url = QUrl::fromEncoded("http://blogsearch.google.com/blogsearch?hl=tr&ie=UTF-8&q=C%2B%2B&&output=rss");
  35.     url.addQueryItem("num", "1");
  36.     url.addQueryItem("start" ,QString::number(randomValue));
  37.     view->load(url);
  38.  
  39.    /* ...... */
  40.  
  41.    setCentralWidget(view);
  42. }
  43. /*
  44. all the functions here
  45. */
To copy to clipboard, switch view to plain text mode 

some of the codes above.
