Unsolved Sizing a bottom dock widget with a TabWidget in the Main Window
-
I'm fairly new to QT and I'm trying to get a Bottom aligned DockWidget containing a TabWidget to size correctly with a central widget, where I would like to have the bottom DockWidget and TabWidget take up about 20% of the Main Window Space while the central widget should take up the rest. But the solutions I have tried have resulted in the central widget either getting a height of 0 or the Tab/DockWidget only getting a single small row at the bottom.
My solution looks something like this:
MainWindow::MainWindow() { // Default size QRect rec = QApplication::desktop()->screenGeometry(); resize(rec.width() * 0.8, rec.height() * 0.8); setCentralWidget(new QWidget(this)); centralWidget()->resize(width(), height() * 0.8); centralWidget()->setSizePolicy(QSizePolicy(QSizePolicy::Minimum, QSizePolicy::Fixed)); m_bottom_container = new QDockWidget(this); m_bottom_container->setAllowedAreas(Qt::BottomDockWidgetArea); m_bottom_container->setFeatures(QDockWidget::NoDockWidgetFeatures); m_botton_view_widget = new QTabWidget(m_bottom_container); m_botton_view_widget->resize(width(), height() * 0.2); m_botton_view_widget->setSizePolicy(QSizePolicy(QSizePolicy::Minimum, QSizePolicy::Maximum)); m_botton_view_widget->setTabPosition(QTabWidget::South); this->addDockWidget(Qt::BottomDockWidgetArea, m_bottom_container); }
