Hi Alex,
I have resized the render window with the following codes:
this->renWin->SetSize(xSize, ySize);
I have followed your suggestion but I haven't risolved my problem.
My application is developed with Visual Studio .Net, Do You think that
this version have a problem with VC++ MFC Multi document and VTK?
My problem is very strange, It appears only when I change fastly the
active CChildFrm.
thx
sorry for my english :)
