Windows XP SP3, Qt 5.0.0 self compiled with -opengl desktop, MSVC 2010 SP1, Nvidia Geforce 250
The was the same issue in Qt 4.7.0 (QTBUG-14083).
QDockWidget, if dragged from its position, loses the titlebar and the inner widget can only be moved while mouse button is pressed. If you release the button then the widget is stuck somewhere on the screen.
This behaviour only occurs if QGLWidget is present in the main window.
The example that was in issue 14083 still illustrates the problem:
#include <QApplication> #include <QPushButton> #include <QDockWidget> #include <QMainWindow> #include <QLabel> #include <QtOpenGL/QGLWidget> int main(int argc, char *argv[]) { QApplication app(argc, argv); QMainWindow w; QPushButton hello("Hello world!"); hello.resize(100, 30); w.setCentralWidget(&hello); QDockWidget *dock = new QDockWidget("gl"); dock->setAllowedAreas(Qt::TopDockWidgetArea); dock->setWidget(new QGLWidget()); w.addDockWidget(Qt::TopDockWidgetArea, dock); QDockWidget *dock2 = new QDockWidget("hi"); dock2->setAllowedAreas(Qt::RightDockWidgetArea); dock2->setWidget(new QLabel("hello", &w)); w.addDockWidget(Qt::RightDockWidgetArea, dock2); w.show(); return app.exec(); }
