# QWidgetImage test
#-------------------------------------------------------------------
# QWidgetImage still has some issues, some examples are:
#
# 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?
#
# 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.
#
# 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.
