Unsolved External WM_DESTROY received... PROBLEM
-
Hi, I have a problem with some QDockWidget...
Long story short, I have a QDockWidget with multiple QDockWidget "inside" of it. If I undock the "main" QDockWidget and then, undock more than one QDockWidget that were "inside" of it, when I dock back the main QDockWidget, only the first undocked secondary QDockWidget keep is position. All the others secondary widgets get destroy with this message :
External WM_DESTROY received for QWidgetWindow(0x1b77143f790, name="dw_savingOptionsWindow") , parent: QWindow(0x0) , transient parent: QWidgetWindow(0x1b771440190, name="dw_settingsWindow")
I guess this is because the parent isn't set... But I don't even know what is a QWidgetWindow...
**dw_settings is the main QDockWidget
**dw_savingOptions is one of the secondary QDockWidgetDid someone had this problem and find any solution...
I could just send a signal to dock back all the secondary QDockWidget when the main QDockWidget is docked but that's an ugly fix.Thanks for any help!
OlivierHere is the part of the code where I set the QDockWidget :
mMainWindowSetting = new QMainWindow(this); mMainWindowSetting->setDockOptions(QMainWindow::AnimatedDocks); mMainWindowSetting->addDockWidget(Qt::TopDockWidgetArea,ui->dw_acqOptions); mMainWindowSetting->splitDockWidget(ui->dw_acqOptions,ui->dw_savingOptions,Qt::Vertical); mMainWindowSetting->addDockWidget(Qt::BottomDockWidgetArea,ui->dw_graphics); mMainWindowSetting->splitDockWidget(ui->dw_graphics,ui->dw_note,Qt::Vertical); ui->sa_settings->setWidget(mMainWindowSetting);
sa_setting is a QScrollArea inside the main QDockWidget (dw_setting)
