Very clever. Have to remember that for the next time someone asks me a question they could have answered for themselves with a little bit of effort.

Hi
thanks for repling
beh,
yes , i see the links (before you put it her "i made effeort") but there is not like what i want
in my case i have in each frame the position of my objects like that

frame[i].object.x//frame[0].object.x=...,frame[1].object.x=.....,...............................
frame[i].object.y
frame[i].object.z

frame[i].object.x//frame[0].object.x=...,frame[1].object.x=.....,...............................
frame[i].object.y
frame[i].object.z

To copy to clipboard, switch view to plain text mode 

so i want when i clic to button i see my object in the new positions in each frame (like an animation)

well, I dont know about ogre, but if you were rendering by qt, then use a basic index for time, or use http://qt-project.org/doc/qt-4.8/qtimeline.html.

then reimplement paintevent to draw your objects using the time index.

void widget::paintEvent(qpaintevent * evt)
{
  int time = getTime(); // get time index from qtimeline or some other counter
 
  // for each object in frame
  drawObjectAt(object, frame[tim].object.x, frame[tim].object.y, frame[tim].object.z); // func that draws an object at specific location.
}

void widget::paintEvent(qpaintevent * evt)
{
  int time = getTime(); // get time index from qtimeline or some other counter

  // for each object in frame
  drawObjectAt(object, frame[tim].object.x, frame[tim].object.y, frame[tim].object.z); // func that draws an object at specific location.
}

To copy to clipboard, switch view to plain text mode 

btw, it looks strange that you seem to have object as a property on frame. Normally animation would be a function of a model or model id.
