[osg-users] Qt, Manipulator keyEvent, Seeking for Help in an Emergency
Hi,
In my codes, i rewrite keyPressEvent function like below:
void AdapterWidget::keyPressEvent( QKeyEvent* event )
{
_gw-getEventQueue()-keyPress( (osgGA::GUIEventAdapter::KeySymbol)
*(event-text().toAscii().data() ) );
}
In my osg codes, i write like this:
bool ManipulatorEventHandler::handle(const osgGA::GUIEventAdapter ea,
osgGA::GUIActionAdapter aa,
osg::Object*, osg::NodeVisitor*)
{
bool alt = (ea.getModKeyMask()
(osgGA::GUIEventAdapter::MODKEY_LEFT_ALT|osgGA::GUIEventAdapter::MODKEY_RIGHT_ALT))
!= 0;
if (alt) return false;
if (ea.getEventType() == osgGA::GUIEventAdapter::KEYDOWN)
{
switch (ea.getKey())
{
case 'r': resetTransform(); break;
}
}
return true;
}
but when i press alt key there is no reponse in my application. I need a help
in an emergency and i'm waiting answer online. Thanks very much.
Thank you!
Cheers,
ramy

[osg-users] Qt + OSG , ManipulatorEventHandler Keyevent
Hi,
I embeded osg in Qt in my program.Now I implement a class
ManipulatorEventHndler to interact with the object in the view. But in my codes
below
bool ManipulatorEventHandler::handle(const osgGA::GUIEventAdapter ea,
osgGA::GUIActionAdapter aa,
osg::Object*, osg::NodeVisitor*)
{
bool alt = (ea.getModKeyMask()
(osgGA::GUIEventAdapter::MODKEY_LEFT_ALT|osgGA::GUIEventAdapter::MODKEY_RIGHT_ALT))
!= 0;
if (alt) return false;
if (ea.getEventType() == osgGA::GUIEventAdapter::KEYDOWN)
{
switch (ea.getKey())
{
case 'd': deleteSelectedNode(); break;
}
}
when i press alt key there is no reponse in my program,but i press 'd' key it
works. I don't know why. As i use Qt, is there something wrong when i implement
the ManipulatorEventHandler?Hope someone can help to solve this problem. Thank
you very very much.
Thank you!

[osg-users] TabBoxDragger Scale Problem
Hi, Now in my codes, i use TabBoxDragger to interact with the model in the scene. But when i scale the model, the x, y ,z three directions scale factor is diffient. I want to scale like glScale(factor, factor, factor) in openGL which means i want scale model with a same factor in the scene. When i interact with the dragger the model can scale in the same size in three directions. I don't know how to solve this problem. Holp someone knows. Thanks very very much. Thank you!
