hyper keys defined already, but these modifiers were missing in
GUIEventAdapter::ModKeyMask, and the EventQueue ingored them as well.
The attached diff/archive adds the missing parts for Super/Hyper
modifier key support.
I'm aware that this might not be supported on all systems/keyboards
out of the box, but decided to submit it anyway because:
- developers are aware of differences between input devices
(Some mice have scroll wheels, others don't. Some have five or
more buttons, some have only one. Some keyboards don't have
numpads, some have AltGr, some don't etc.)
- even if someone relies on Hyper/Super in distributed software,
this is easy to fix and doesn't create lock-in conditions
- while the names Hyper/Super may only be common on X11, they are
just symbol names and not OS-specific
- even though some systems might not offer these additional modifiers
by default, it's likely that all of them have at least 8 modifier
levels internally, so it should only be a matter of OS configuration
to make them work
- having super/hyper available is useful to offer a user ways
to define local key definitions that are safe from collisions with
predefined "official" key assignments"
Attached is modified source of AdapterWidget.cpp file from osgviewerQT
example. Original was token today from SVN - trunk. (2.3.6).
--mdi option needs to be set to run MDI version.
Few notes:
- tested on Windows box (Win XP)
- using QT4
- I was not able to execute the example with QOSGWidget - had same
error like described in [osg-users] "fate error using QOSGWidget in
develop release
2.3.0" thread from Shuxing Xiao, 2008-01-08.
- problems are described in source

And Later post:
The problem of keypress events was solved by QT community, attached is
repaired AdapterWidget.cpp file.
In the AdapterWidget class constructor following line was added:
setFocusPolicy(Qt::ClickFocus);
Scene disappearing by resizing to minimum still needs to be fixed..."
and a new scheme for computing the scaling when using autoscale that introduces smooth
transitions to the scaling of the subgraph so that it looks more natural.
other GUI toolkit examples. It now takes a model file as command-line
argument (complaining if there isn't one), and its startup window size
is now actually applied (it used to be too small). I tested this with a
unicode-build of wxWidgets, as that is the recommended build type on
Linux with GTK. I'm pretty sure this version of the example will work
for the ANSI build as well, but I have no way of testing."
creating subclasses of osg::Array that referenced data
stored an application's internal data structures. I took
a stab at implementing that and ran into a couple of
downcasts in Geometry.cpp. Enclosed is my take at fixing
those along with a simple example of how to do this."
fullscreen mode and back between views. (To activate, double click on
the view to toggle.) It demonstrates/uses the new one-liner fullscreen
method introduced in Leopard. Code will still compile and run in
pre-Leopard (thanks to Obj-C dynamic/late binding), but code path is
treated as a no-op in those cases."
enhanced version of PolytopeIntersector.
New features of PolytopeIntersector :
* Dimension mask: The user may specify the dimensions of the
primitives to be tested. Checking polytope-triangle and
polytope-quad intersections is rather slow so this can
be turned off.
* Reference plane: The resulting intersections are sorted
by the distance to this plane.
New memebers of PolytopeIntersector::Intersection :
* distance: Distance of localIntersectionPoint to the reference plane
* maxDistance: Maximum distance of all intersectionPoints to the
reference plane.
* intersectionPoints: The points intersecting the planes of the polytope
or points completely inside the polytope.
* localIntersectionPoint: arithmetic mean of all intersection points
* primitiveIndex: Index of the primitive that intersected
I added some more output to the example osgkeyboardmouse."
with the original AdapterWidget implementation still available by default. The new implementation can be accessed by running:
osgviewerQT cow.osg --QOSGWidget
all wonky when I resize the SDL window. I'm not sure if this bug has
always existed or not, but according to the SDL documentation this
operation should be safe regardless, and doesn't not introduce the need
for extra memory management (that is: there is no need to "cleanup" the
old screen variable, that is all handled by SDL for us).
"
- set the resolution of the shadow map; it calls dirty() to
re-initialize at next update
- keep a list of Shader objects to use instead of the default ones, if
the list is empty, the default shaders are used
- explicitly create the Uniform variables, so that subsequent additions
that require more Uniforms can put them in a central place
- set a Light or LightSource to use explicitly for shadow casting,
allows multiple lights in the scene, with one casting shadows
There are two additions that do not ( yet ) function correctly, but in
the present usage they do not interfere with the regular usage of the
techique:
- support for using spotlights, it's using Light.spotCutoff to determine
if it's a spot-light and not point-light,
there is an error in the setup of either the shadow camera or the
texgen, most likely due to the direction of the spotlight, since the
position is being used just like in point or directional lights.
- creation of a debugHUD
the hud is created properly, ( the example included shows it ), but
it displays only white, there has been some discussion of displaying the
shadow map, but I could not find it, the addition of a simple fragment
shader with the appropriate color transform should get this going."
"" for all platforms except Cygwin where its set to "cygwin_" and Mingw where
it is set to "mingw_". Updated osgDB::Registry to look for these for the plugins.
Updated the osgintrospection example to search for these names as well.
(a) some objects behind the camera can cast shadow
(b) object aboive the camera can cast shadow
then i fixed the shadow map orientation, now screen x coordinate alinged which improve the quality"
- When using a large numbrer of files, the command line was too long;
Added a -files option that allow to store filenames in a file (one file
per line)
- Added some more intuitive key bindings for controls (left, right, + ,
-)
- Set the texture wrapping to CLAMP_TO_EDGE (it's cleaner now)

Attached the modified version of MFC_OSG_MDIView.cpp and MFC_OSG_MDIView.h."
Note from Robert Osfield, submission came with wrong header file, so have had
to guess at what it should be, fingers crossed it worn't break windows build... :-)
osgviewerWX: "To make the example compile using a wx build non UNICODE based.
Tested on Linux with wxGTK 2.8.4"
osgviewerFOX: "Added removeChore() call in the FOX_OSG_MDIView destructor to get rid of a Trace/BPT trap
error on exit on Linux. BTW this is suggested also in the FOX documentation."
1) added texture->setResizeNonPowerOfTwoHint(false); when loading an
image. It speeds up by 10 the loading of large images.
2) added a --disk option : only a filelist is read, images are only
loaded when needed. It allows to handle very large set of very large
images that would not fit in memory. Nothing change when the option is
not set."
Changes:
MFC_OSG.cpp:
Removed pixelformatdesciptor from the class initialization.
Used setInheritedWindowPixelFormat to true so it will setup the pixelformat for the window.
Added class destructor code.
MFC_OSG.h:
Removed the ref_ptr on osgViewer::Viewer
MFC_OSG_MDIViewer.cpp:
Changed the OnDestroy function code.
Added WaitforSingleObject with thread handle for the MFC render handle.
MFC_OSG_MDIView.h:
Added class variable for MFC Render Thread Handle for use with the WaitforSingleObject.
"
multiple GraphicsWindows, this singleton is accessable via GUIEventEvent::getAccumulatedEventState().
Added use of this new singleton in GraphicsWindow* implementations.
Added WindowSizeHandler to osgkeyboard to help with debugging of event state
between windows.
completed the new registration of the plugin-readerwriters
("REGISTER_OSGPLUGIN") according to your osgstaticviewer-example (see
attachment, based on today's svn)."
Added and cleaned up DeleteHandler calls in osgViewer to help avoid crashes on exit.
Changed DatabasePager across to dynamically checcking osg::getCompileContext(..)
Updated wrappers.
I've also added a little offset to the windows' positions so that their decoration falls inside the desktop and we can manipulate them - it looks a bit less "made out of wood"."

allows geometry setup code to flip the t tex coord to render the movie the correct way up.
