[osg-users] How to change the text with osg::Text?

2012-10-15 Thread Eungil 
Hi,

I am a very new, and i got a problem with using osg::Text.

I set the text like this blow.
osg::Geode* textGeode = new osg::Geode();
osgText::Text*  textLabel = new osgText::Text();

root-addChild(textGeode); // root is a point of osg::group()

then, i want to display the numbers being continuelly increasing.
the screen I guess will be showen up like this.
0, 1, 2, 3, 4, 5..

In order to achieve this, I typed code within while roop.

wchar_t strTmp[100];
swprintf(strTmp, L%.3d, 0);
textLabel-setText(strTmp);
int index = 0 ;
while(!viewer.done())
{
  swprintf(strTmp, L%d, ++nIndex);
  textLabel-update();  
  viewer.frame();
}

However, the result is stopped. I think the problem is related to 
textLabel-update() line.

Please, anyone tell me how to change (or update) the text frequently?

Thank you!

Cheers,
Eungil

Hi

call textLabel-setText(strTmp);
instead of update()

Cheers.

  Also, you may need to set the dataVariance on the osgText to Dynamic.
