This now builds with cmake if added to the osg examples tree. A change to
|
||
|
|
examples/CMakeLists.txt is also required.
|
||
|
|
|
||
|
|
It is also possible to build this stand alone with qmake using the .pro file.
|
||
|
|
I think I've made the .pro sufficiently generic to build anywhere. The first
|
||
|
|
couple of lines in the file need to be adjusted for anyone's local environment.
|
||
|
|
|
||
|
|
This builds and runs on Linux and Win32 OK. See status section.

Mac has some problems. Qt was 4.4.2 and Mac OS X 10.5.2. 1) Had to adjust the
|
||
|
|
.pro file to hide QT_NO_DEBUG_OUTPUT or problems with a Frameworks header. 2)
|
||
|
|
Had to eliminate the outboard window to avoid a crash. 3) Only the lower-left
|
||
|
|
of the 4 views is OK. The other 3 views filled with frame buffer garbage. 4)
|
||
|
|
Maximize twice and we loose the lower-left too.

My colleague Liz Martin collaborated on the design and did the Qt work.

Linux/Win32 builds (on Mac substitute make for gmake):

gmake clean

qmake qosgwidget.pro
|

gmake

|
||
|
|
---------------
|
||
|
|
o Implemented the skeleton of CompositeViewerQOSG and ViewQOSG (in
|
||
|
|
QOSGWidget.cpp)
|
||
|
|
|
||
|
|
o In testMainWin.ui, osgGraphicsArea is a "promoted" widget: It is promoted to
|
||
|
|
CompositeViewerQOSG
|
||
|
|
|
||
|
|
CompositeViewerQOSG inherits from both QWidget and osgViewer::CompositeViewer
|
||
|
|
|
||
|
|
o ViewQOSG inherits from QOSGWidget (which inherits from QWidget) and
|
||
|
|
osgViewer::View
|
||
|
|
|
||
|
|
o Bagged on allowing tab focus between the ViewQOSG widgets because:
|
||
|
|
|
||
|
|
o on resizing, OSG's CompositeViewer sets the camera (and view) focus to its
|
||
|
|
first osgViewer::View, which can create a disconnect between the Qt widget
|
||
|
|
(ie ViewQOSG) that has the focus and is receiving keyboard events, and the
|
||
|
|
actual ViewQOSG that the composite viewer acts on
|
||
|
|
|
||
|
|
o From empirical observation, it didn't seem to matter which ViewQOSG
|
||
|
|
received the keyboard event; the composite viewer applied the designated
|
||
|
|
action to the view the composite viewer consider current
|
||
|
|
|
||
|
|
o TAB focus would be given to a ViewQOSG even it had been completely
|
||
|
|
collapsed via QSplitter action in the QMainWindow. I was not successful
|
||
|
|
in my attempts to modify this behavior.

|
||
|
|
---------------
|
||
|
|
|
||
|
|
o In this area, in testMainWin.ui, not only is osgGraphicsArea a promoted
|
||
|
|
widget (to CompositeViewerQOSG), but the 4 subviews are now also promoted
|
||
|
|
widgets, to ViewQOSG.
|
||
|
|
|
||
|
|
o I eliminated QOSGWidget::eventFilter().
|
||
|
|
|
||
|
|
o In QOSGWidget::QOSGWidget(), I no longer take x, y, width, and height from
|
||
|
|
the 'parent', I simply take it from itself.
|
||
|
|
|
||
|
|
Unfortunately, these changes don't help the Windows exe at all. Linux
|
||
|
|
continues to run just fine. But Windows doesn't see that TAB, and doesn't see
|
||
|
|
any *results* of the Key presses (Like 'l' to change lighting.)

|
|
o Applied Martin Beckett's fix for WIN32 event queue handling.

|
|
5/19/09 Status
|
||
|
|
---------------
|
||
|
|
|
||
|
|
o Altered WIN32 event queue handling to not skip key events.
|
||
|
|
|
||
|
|
o Got Mac to build and sort of run. Qt is 4.4.2 and Mac OS X 10.5.2.
|
||
|
|
1) Had to adjust the .pro file to hide QT_NO_DEBUG_OUTPUT or problems with
|
||
|
|
a Frameworks header. 2) Had to eliminate the outboard window to
|
||
|
|
avoid a crash. 3) Only the lower-left of the 4 views is OK.
|
||
|
|
The other 3 views filled with frame buffer garbage. 4) Maximize
|
||
|
|
twice and we loose the lower-left too.

o Simon Loic provided cmake infrastructure and help me debug some cmake
|
||
|
|
configuration problems. I needed to wipe my out-of-source object tree
|
||
|
|
and start over explicitly defining QT version 4, ala:
|
||
|
|
ccmake ../OpenSceneGraph-2.8.1 -DDESIRED_QT_VERSION=4
|
||
|
|
|
||
|
|
o Reimplemented QWidget::paintEngine to return 0 as recommended by doc.
|
||
|
|
This is purported to stop Qt from rendering anything in our windows.
|
||
|
|
|
||
|
|
o Eric Pouliquen recommended replacing setAttribute Qt::WA_PaintOnScreen
|
||
|
|
and Qt::WA_NoSystemBackground with Qt::WA_OpaquePaintEvent. Seems best
|
||
|
|
if we add Qt::WA_OpaquePaintEvent, get rid of Qt::WA_NoSystemBackground,
|
||
|
|
but keep Qt::WA_PaintOnScreen.
