Insert Drawable to osgWidget

[marco....@elmansrl.eu]

Hi guys,

I need to insert drawables like lines, polygons to the viewer.

Then, the idea it's to create an osgWidget::Box and insert through the method  getGeode()->addDrawable a simple drawable...

///*Crea la label*/

osgWidget::Label* createLabel(const std::string& name, const std::string& text, float size, const osg::Vec4& color)

{

osg::ref_ptr<osgWidget::Label> label = new osgWidget::Label(name);

label->setLabel(text);

label->setFont("fonts/arial.ttf");

label->setFontSize(size);

label->setFontColor(1.0f, 1.0f, 1.0f, 1.0f);

label->setColor(color);

label->addSize(10.0f, 10.0f);

label->setCanFill(true);

return label.release();

mainBox->attachMoveCallback();

mainBox->getBackground()->setColor(1.0f, 1.0f, 1.0f, 1.0f);

mainBox->addWidget(createLabel("title", "Tabs Demo", 15.0f, osg::Vec4(1.0f, 0.0f, 0.0f, 1.0f)));

mainBox->addWidget(createLabel("title", "TEST", 40.0f, osg::Vec4(0.0f, 1.0f, 0.0f, 1.0f)));

if (mainBox->getGeode()!=nullptr) {

osg::Geometry* line = createScene();

mainBox->getGeode()->addDrawable(line);

cout << mainBox->getGeode()->containsDrawable(line) << endl;

}

return mainBox.release();

}

int main(int argc, char** argv)

{

osgViewer::Viewer viewer;

osg::ref_ptr<osgWidget::WindowManager> wm = new osgWidget::WindowManager(&viewer, 1024.0f, 768.0f, 0xf0000000);

osg::Camera* camera = wm->createParentOrthoCamera();

wm->addChild(createSimpleTabs(0.0f, 0.0f));

wm->resizeAllWindows();

osg::ref_ptr<osg::Group> root = new osg::Group;

root->addChild(camera);

viewer.setSceneData(root.get());

viewer.setUpViewInWindow(50, 50, 1024, 768);

viewer.addEventHandler(new osgWidget::MouseHandler(wm.get()));

viewer.addEventHandler(new osgWidget::KeyboardHandler(wm.get()));

viewer.addEventHandler(new osgWidget::ResizeHandler(wm.get(), camera));

viewer.addEventHandler(new osgWidget::CameraSwitchHandler(wm.get(), camera));

return viewer.run();

}

What I get is to have the two labels in the hbox .. but I can't see the line ...

What am I doing wrong?
