// 1. Editing in the QTextEdit doesn't work. Also when started with
// --useBrowser, editing in the search field on YouTube doesn't
// work. But that same search field when using QWebViewImage
// works... And editing in the text field in the pop-up getInteger
// dialog works too. All these cases use QGraphicsViewAdapter
// under the hood, so why do some work and others don't?
//
// <<< FIXED, need TextEditorInteraction >>>
//
// a) osgQtBrowser --useWidgetImage [--fullscreen] (optional)
// b) Try to click in the QTextEdit and type, or to select text
// and drag-and-drop it somewhere else in the QTextEdit. These
// don't work.
// c) osgQtBrowser --useWidgetImage --sanityCheck
// d) Try the operations in b), they all work.
// e) osgQtBrowser --useWidgetImage --useBrowser [--fullscreen]
// f) Try to click in the search field and type, it doesn't work.
// g) osgQtBrowser
// h) Try the operation in f), it works.
//
// 2. Operations on floating windows (--numFloatingWindows 1 or more).
// Moving by dragging the titlebar, clicking the close button,
// resizing them, none of these work. I wonder if it's because the
// OS manages those functions (they're functions of the window
// decorations) so we need to do something special for that? But
// in --sanityCheck mode they work.
//
// a) osgQtBrowser --useWidgetImage --numFloatingWindows 1 [--fullscreen]
// b) Try to drag the floating window, click the close button, or
// drag its sides to resize it. None of these work.
// c) osgQtBrowser --useWidgetImage --numFloatingWindows 1 --sanityCheck
// d) Try the operations in b), all they work.
// e) osgQtBrowser --useWidgetImage [--fullscreen]
// f) Click the button so that the getInteger() dialog is
// displayed, then try to move that dialog or close it with the
// close button, these don't work.
// g) osgQtBrowser --useWidgetImage --sanityCheck
// h) Try the operation in f), it works.
//
// 3. (Minor) The QGraphicsView's scrollbars don't appear when
// using QWidgetImage or QWebViewImage. QGraphicsView is a
// QAbstractScrollArea and it should display scrollbars as soon as
// the scene is too large to fit the view.
//
// <<< FIXED >>>
//
// a) osgQtBrowser --useWidgetImage --fullscreen
// b) Resize the OSG window so it's smaller than the QTextEdit.
// Scrollbars should appear but don't.
// c) osgQtBrowser --useWidgetImage --sanityCheck
// d) Try the operation in b), scrollbars appear. Even if you have
// floating windows (by clicking the button or by adding
// --numFloatingWindows 1) and move them outside the view,
// scrollbars appear too. You can't test that case in OSG for
// now because of problem 2 above, but that's pretty cool.
//
// 4. (Minor) In sanity check mode, the widget added to the
// QGraphicsView is centered. With QGraphicsViewAdapter, it is not.
//
// a) osgQtBrowser --useWidgetImage [--fullscreen]
// b) The QTextEdit and button are not in the center of the image
// generated by the QGraphicsViewAdapter.
// c) osgQtBrowser --useWidgetImage --sanityCheck
// d) The QTextEdit and button are in the center of the
// QGraphicsView.
