Hi all, When testing Qwt with Qt5 I was running a NX ( http://www.nomachine.com ) remote desktop. Local was a SuSE/Linux 11.2, remote ran a SuSE 12.1/Linux.
With about half of the Qwt applications I had the following effect: as soon as I move the mouse over the application window ( Xfce4, focus follow mouse is enabled ) inside the remote desktop the complete screen on my local system ( the local desktop ! ) is black. When I move the mouse out of the window the screen is o.k. again. Doing all the same with Qt 4.8.0 or running the applications with Qt5 and X11 remote doesn't show any problem. Bugs like these are really hard to reproduce - too many candidates to be responsible - but if someone is interested in investigations let me know. Uwe Below is a small demo showing the effect on my box. --- #include <qapplication.h> #include <qmainwindow.h> #include <qtoolbar.h> #include <qtoolbutton.h> #include <qlayout.h> class MainWindow: public QMainWindow { public: MainWindow() { QWidget *w = new QWidget( this ); QHBoxLayout *layout = new QHBoxLayout( w ); layout->addWidget( new QWidget() ); setCentralWidget( w ); QToolBar *toolBar = new QToolBar( this ); QToolButton *button = new QToolButton(); toolBar->addWidget( button ); addToolBar( toolBar ); } }; int main( int argc, char **argv ) { QApplication a( argc, argv ); MainWindow w; w.resize( 600, 400 ); w.show(); return a.exec(); } _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
