I think the video of VLC widget is rendered on another window surface reparented to the Qt Widget. If you want transparent window surface on top of eachother, it is window compositing, not regular rendering. You should check the hierarchy of XWindow, or of Windows Window to see if you have more than one native window per Qt Window.

Here is what I wrote a looong time ago (still the first hit of googling for 'transparent qwebview'): http://labs.qt.nokia.com/2009/06/30/transparent-qwebview-or-qwebpage/ See if it works for you. Thank you that's exactly what I wanted, works brilliantly! Turns out my google-fu is not as strong as I thought. Hi, I've been playing with this a bit more and have come across another problem which has stumped me. I'm trying to have the QWebView render on top of a video window rendered with vlc so the video is visible through the transparent elements. However the QWebView is obstructing the video. If I swap the QVlcPlayer for a QTextEdit then it displays fine so it must be something with my custom widget but I'm lost to even know where to start looking. Any help would be greatly appreciated! Here's my Qt VLC code in QVlcPlayer.h... #ifndef QVLC_PLAYER_H #define QVLC_PLAYER_H #include <vlc/vlc.h> #include <QWidget> class QVlcPlayer : public QWidget { Q_OBJECT libvlc_instance_t *_vlcinstance; libvlc_media_player_t *_mp; libvlc_media_t *_m; public: QVlcPlayer(QWidget *widget = 0) : QWidget(widget) { const char * const vlc_args[] = { "-I", "dummy", "--ignore-config", "--extraintf=logger", "--verbose=2", "--plugin-path=plugins" }; _vlcinstance=libvlc_new(sizeof(vlc_args) / sizeof(vlc_args[0]), vlc_args); _mp = libvlc_media_player_new (_vlcinstance); } ~QVlcPlayer() { libvlc_media_player_stop (_mp); libvlc_media_player_release (_mp); libvlc_release (_vlcinstance); } public slots: void playFile(QString file) { _m = libvlc_media_new_location (_vlcinstance, file.toAscii()); libvlc_media_player_set_media (_mp, _m); #if defined(Q_OS_WIN) libvlc_media_player_set_hwnd(_mp, this->winId()); // for vlc 1.0 #elif defined(Q_OS_MAC) libvlc_media_player_set_agl (_mp, this->winId()); // for vlc 1.0 #else //Linux libvlc_media_player_set_xwindow(_mp, this->winId()); // for vlc 1.0 #endif libvlc_media_player_play (_mp); } }; #endif and my main.cpp code... #include "QVlcPlayer.h" #include <QApplication> #include <QWebView> #include <QWebSettings> int main(int argc, char *argv[]) { QApplication a(argc, argv); QWidget window; window.resize(1280, 720); QVlcPlayer player(&window); player.setGeometry(0, 0, 1280,720); player.playFile("udp://@239.71.0.0:1234<http://239.71.0.0:1234>"); QWebView *view = new QWebView(&window); QPalette pal = view->palette(); pal.setBrush(QPalette::Base, Qt::transparent); view->page()->setPalette(pal); view->setAttribute(Qt::WA_OpaquePaintEvent, false); view->load(QUrl("test.html")); view->setGeometry(10, 10, 1260, 680); window.show(); return a.exec(); } Thanks in advance!
