When is used both texture fonts and order textures(AIS_TexturedShape) in one
presentation, opengl context lost drawing textures on the firts update.
If using bitmap fonts, all is works.

Hi,

I am facing one problem in displaying text when textured mode is enabled.I want
to display text on Textured shape when the mouse rolls over it. The code which I
have written for displaying the AISTextured box and highlighting the text is
given below:

gp_Pnt pnt(100,100,100);
TopoDS_Shape theBox = BRepPrimAPI_MakeBox(pnt,500,500,500);
Handle(AISTextureShape) m_AISTShape = new AISTextureShape(theBox);
TCollection_AsciiString TFileName("blablabla");
m_AISTShape->SetTextureFileName(TFileName);
m_AISTShape->SetTextureMapOn();
m_AISTShape->SetTextureScale(Standard_True, 1, 1);
m_AISTShape->SetTextureRepeat(Standard_True, 3, 3);
m_AISTShape->SetTextureOrigin(Standard_True, 0, 0);
m_AISTShape->SetDisplayMode(3);
m_hAISContext->Display(m_AISTShape,Standard_False);
m_hAISContext->UpdateCurrentViewer();

I am able to draw the Box having texture. For highlighting the text I am
overriding the Compute function of AISTextureShape as below

void AISTextureShape::Compute(const Handle(PrsMgr_PresentationManager3d)&
p_pPrsManager,const Handle(Prs3d_Presentation)& p_pPrs,const Standard_Integer
p_iMode){
switch (p_iMode) {
case 0: // Wireframe
{
p_pPrs->Clear();
gp_Pnt l_PrsPnt = GetPrsPoint();
StdPrs_WFDeflectionShape::
Add(p_pPrs,myshape,myDrawer);
TCollection_ExtendedString l_TCoText =
TCollection_ExtendedString(m_strTextName);
Prs3d_Text::Draw(p_pPrs,myDrawer,l_TCoText,
l_PrsPnt);
}
break;
default:
AIS_TexturedShape::Compute( p_pPrsManager,
p_pPrs, p_iMode);
break;
} // end switch
}

but the problem I am facing is this that highlighted text becomes a blue box
when I roll the mouse cursor over the box and the box looses its texture property.

I tried a lot to resolve this problem but I didn't get any solution. I think
this a bug in opencascade. if any body knows then please help me how to resolve
this problem.

Thanks
Anjul
Additional information
and documentation updates		Documentation remark, added by Pavel Supryatkin (psn) 2010-09-02 16:29:04:

Changes:
On Windows, OpenGL attributes related with textures are stored before
generation of texture fonts and restored after this, to eliminate
conflicts with other functionality dealing with textures.
