Floating windows constrained to within the MainWindow?

[guilugi]

You can use QDockWidget, it seems to be the easiest solution

By the way, you can prevent docked widgets from floating outside of the mainwindow :

dockwidget->setFeatures( QDockWidget::DockWidgetMovable | QDockWidget::DockWidgetClosable)

dockwidget->setFeatures( QDockWidget::DockWidgetMovable | QDockWidget::DockWidgetClosable)

To copy to clipboard, switch view to plain text mode 

Just omit the feature

QDockWidget::DockWidgetFloatable

QDockWidget::DockWidgetFloatable

To copy to clipboard, switch view to plain text mode
