1) Problem description:<br>
I need to redraw the vtkRenderer when users click the someplace of
window. Firstly, the all props were deleted:<br>
m_Renderer-&gt;RemoveAllViewProps();<br>
<br>
Then, these codes were used to redraw the vtkRenderer<br>
<br>
vtkPoints&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * pts&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = vtkPoints::New();<br>
vtkUnstructuredGrid * aTriangleGrid&nbsp;&nbsp; = vtkUnstructuredGrid::New();<br>
vtkDataSetMapper&nbsp;&nbsp;&nbsp; * aTriangleMapper = vtkDataSetMapper::New();<br>
vtkActor&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * Actor&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = vtkActor::New();<br>
<br>
// some codes to create the Props<br>
<br>
m_Renderer-&gt;AddViewProp( Actor );<br>
<br>
pts-&gt;Delete();<br>
aTriangleGrid-&gt;Delete();<br>
aTriangleMapper-&gt;Delete();<br>
Actor-&gt;Delete();<br>
<br>
Finally, The memory usage was growing with redrawing the vtkRenderer<br>
<br>
2) My environment<br>
Windows XP SP2<br>
mingw32-gcc-3.4.5<br>
wxWidgets 2.8.9 linked as dll<br>
VTK 5.0 linked as dll<br>
wxVTKRenderWindowInteractor cvs version (up to now)<br>
<br>
<br>
I know this problem can be avoided by using linker's /delayload flag of
MFC, but how to fix this problem for mingw?<br>
<br>
Thanks a lot!<br>
