window.
The win32 implementation is still in its original shape since I have no win32
implementation available.
I have chosen the enum approach for the first cut. That is benefitial since
the user does not need to track creation of mouse cursors for different
windows and displays in presence of multiple viewer windows.
The default set of available mouse shapes is the same set that was available
with glut. That set served many OpenGL applications well, so the hope is that
this is enough.
Even though, that implementation is still extensible:
I have digged out the way SDL defines new mouse cursors and added a still
documented out function prototype in the GraphicsWindow that can be used to
extend the current implemtation for arbitrary mouse shapes. That is not
implemented yet.
I hope that somebody with a win32 test system can catch up that implementation
on win32."
implementation of GraphicsWindow:
- usage of WindowData, you can specify an existing window to use via
osg::Traits
- implementation of setScreenResolution and setScreenRefreshRate
- implementation of setWindowDecoration when window is already created.
There seems to be a bug regarding multiple threads and closing windows,
see my other mail on osg-users.
"
Most of the code is from the osgviewer application, I have took the fullscreen handler and the threading one, and I have just added a fonctionality to be able to change the screen resolution in windowed mode."
returned from Viewer::getContexts/getWindows will be the left most window on the lowest screen number.
Added ability for StatsHandler and HelpHandler to support end users setting their
Camera's graphics context.
related support into osgViewer::Viewer and osgViewer::StatsHandler.
Added lazy updating of text in StatsHandler HUD to minimize the impact of
slow text updating on observed frame rates.
Added setting of osg_SimulationTime and osg_DeltaSimulationTime to the uniforms set by SceneView
Added frame(double simulationTime) and advance(double simulationTime) parameters to
osgViewer::SimpleViewer, Vewer and CompositeViewer.
Updated various examples and Nodes to use SimulationTime where appropriate.
* Setup proper pixel format for ATI boards (removal of WGL_SWAP_METHOD_ARB specification from the requested pixel format since unsupported by the ATI driver)
* Fix to create sample OpenGL window on the proper display device. This is the temporary window used to choose the desired pixel format. In the previous version, this window was always created on the primary display device, even though it had potentially different pixel formats compared to the target display device containing the window to be created.
* Implementation of WindowingSystemInterface::setScreenResolution() method
* Implementation of WindowingSystemInterface::setScreenRefreshRate() method
* Implementation of GraphicsWindow::requestWarpPointer() method
* Implementation of GraphicsWindow::useCursor() method and associated trait support. This can be used in two ways; first, when the graphics trait requested indicates that no cursor should be present, a new cursor-less window class is used to create the window. When a cursor-enabled window creation is requested, another window class is used. After creation of a window, it is also possible to toggle the cursor state by using the GraphicsWindow::useCursor method.
* The way the mouse behaves is now compatible with the behaviour seen on X11; i.e. when pressing a mouse button, the window where the pointer is located will capture the mouse input and release it only after the button has been released. This results in all mouse movement events being dispatched to the window where the button was pressed initially until it is released. This improves the interaction with graphics windows.
* Preparation work has been done to support the ability of moving a window from one screen to another screen and recreating its rendering context when this happens. This has been tested with a mix of NVIDIA and ATI cards and works properly. For the moment being, this feature is commented out due to changes in the core OSG libraries that have been done but need to be submitted later this week for approval by Robert.
Upcoming features
* Support for moving windows from one screen to another screen seamlessly
* Ability to set the window (i.e. the application itself creates the rendering window and passes it to the GraphicsWindowWin32 class)
* Other miscellaneous items"
---------------------------------------------------
+ Multi-display-support
+ automatic hiding of the menubar/dock if one of the windows intersects
the menubar/dock
Bugfixes:
+ event-handling was done by the first opened window, other windows did
not receive events -- fixed
+ mouse-coordinates were absolute, now they are relative to the window.
known bugs:
+ windows with decoration and in fullscreen-size are moved by the system
a little bit, so that the titlebar is accessible/visible. So if you want
real fullscreen-windows, don't decorate the window :)
I updated the XCode-project-file so all ported examples are linked
against osgViewer."
as osg::GraphicsOperation. Unpdated parts of OSG depending upon these.
Added a virtaul bool valid() method to osg::GraphicsContext to allow apps to
test whether a valid graphis context has been created or not.
added frame stamp updating and update traversal to osgViewer::Scene/Viewer.
Updated osgcamera example to use new Viewer API calls instead of using local
rendering calls.
