Re: [osg-users] Implementation of movement, rotation of scale
Hi, i finded code, but in this function is failed why?
Code:
osg::Node* addDraggerToScene(osg::Node* scene, const std::string& name)
{
scene->getOrCreateStateSet()->setMode(GL_NORMALIZE,
osg::StateAttribute::ON);
osg::MatrixTransform* selection = new osg::MatrixTransform;
selection->addChild(scene);
osgManipulator::Dragger* dragger = createDragger(name);
osg::Group* root = new osg::Group;
root->addChild(dragger);
root->addChild(selection);
float scale = scene->getBound().radius() * 1.6;
dragger->setMatrix(osg::Matrix::scale(scale, scale, scale) *
osg::Matrix::translate(scene->getBound().center()));
osgManipulator::GridConstraint *con = new
osgManipulator::GridConstraint(*selection, osg::Vec3(0, 0, 0), osg::Vec3(30,
30, 30));
osg::ref_ptr m_pManipulator = new
osgManipulator::TabBoxDragger;
m_pManipulator->addConstraint(con);
dragger->addConstraint(con);
dragger->addTransformUpdating(selection);
// we want the dragger to handle it's own events automatically
dragger->setHandleEvents(true);
// if we don't set an activation key or mod mask then any mouse click on

dragger->setActivationModKeyMask(osgGA::GUIEventAdapter::MODKEY_CTRL);
dragger->setActivationKeyEvent('a');
return root;
}
after RETURN failde:(

Thank you!

[osg-users] QPropertyAnimation with openscengraph window
Hi, i have QWidget and i want him to disappear duration X time. In qt my code

Thank you!

Maxim
Code:
#include "mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),

{

ui->pushButton->setGraphicsEffect(eff);
QPropertyAnimation *a = new QPropertyAnimation(eff,"opacity");
a->setDuration(3500);
a->setStartValue(0);
a->setEndValue(1);
a->setEasingCurve(QEasingCurve::InCubic);
a->start(QPropertyAnimation::DeleteWhenStopped);
//connect(a,SIGNAL(finished()),this,SLOT(hideThisWidget()));

}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::hideButton()
{
QGraphicsOpacityEffect *eff = new QGraphicsOpacityEffect();
ui->pushButton->setGraphicsEffect(eff);
QPropertyAnimation *a = new QPropertyAnimation(eff,"opacity");
a->setDuration(3500);
a->setStartValue(1);
a->setEndValue(0);
a->setEasingCurve(QEasingCurve::OutBack);
a->start(QPropertyAnimation::DeleteWhenStopped);
}
but then i use this code with OSG, he doesn't work.
The window where everything happens is osgViewer::CompositeViewer.
How can I solve this problem?
