Hi,
iam using the trunk of OSG
i ve a simple code snipped
a Group with a dragger and two transformmatrix objects
and their childs
there is no problem to call the method
pDragger->addTransformUpdating( pTransformBrick1 );
pDragger->addTransformUpdating( pTransformBrick2 );
but when i call the methods
pDragger->removeTransformUpdating( pTransformBrick1 );
pDragger->removeTransformUpdating( pTransformBrick2 );
the code crashes with "Expression: ("This->_has_container()",0)
in dragger.cpp line 204
Code:
void Dragger::removeTransformUpdating(osg::MatrixTransform* transform)
{
for(Dragger::DraggerCallbacks::iterator itr = _draggerCallbacks.begin();
itr != _draggerCallbacks.end();
++itr)
here is my test programm
Code:
int main( int argc, char **argv )
{
osgViewer::Viewer viewer;
osg::ref_ptr<osg::Group> pRoot = new osg::Group;
osg::ref_ptr<osg::Node> pBrick1 = osgDB::readNodeFile(
"D:\\bricks\\obj\\3001.obj" );
osg::ref_ptr<osg::Node> pBrick2 = osgDB::readNodeFile(
"D:\\bricks\\obj\\3005.obj" );
osg::MatrixTransform* pTransformBrick1 = new osg::MatrixTransform;
pTransformBrick1->addChild( pBrick1 );
osg::MatrixTransform* pTransformBrick2 = new osg::MatrixTransform;
pTransformBrick2->addChild( pBrick2 );
osgManipulator::Dragger* pDragger = 0;
osg::ref_ptr<osgManipulator::TabBoxDragger> pTabBoxDragger = new
osgManipulator::TabBoxDragger();
pTabBoxDragger->setupDefaultGeometry();
pDragger = pTabBoxDragger;
pRoot->addChild(pTransformBrick1);
pRoot->addChild(pTransformBrick2);
pRoot->addChild( pDragger );
float scale = pBrick1->getBound().radius() * 1.6;
pDragger->setMatrix(osg::Matrix::scale( scale, scale, scale ) *
osg::Matrix::translate( pBrick1->getBound().center() )
);
pDragger->addTransformUpdating( pTransformBrick1 );
pDragger->addTransformUpdating( pTransformBrick2 );
pDragger->removeTransformUpdating( pTransformBrick1 );
pDragger->removeTransformUpdating( pTransformBrick2 );
pDragger->setHandleEvents(true);
osgUtil::Optimizer optimizer;
optimizer.optimize( pRoot.get() );
viewer.setSceneData( pRoot.get() );
return viewer.run();
}
Why doesnt it work?
Is there another way to activate and deactivate the dragger to the nodes?
Thank you!
Cheers,
Matthias
