add the code segment given below in OnCreate() Of your view class.
this->renWin->SetWindowId(this->GetSafeHwnd());
Now, if you want capture the WM_LBUTTONDOWN event, then go to windowproc()
function in your view class and comment

Hi,
i've got Problems after clipping data (SetClipFunction(plane)) from a
PolyData volume with vtkClipPolyData.
I put the clipped data into a new PolyData structure and wanna build a
locator on it. But if the locator reads the polydata, it sometimes produces
an error ('vktcommon.dll memory access'-error while checking number of IDs).
This error occurs, if the clipped data does not contain a special part of
the volume. If i invert the clipped data, the error does not occur.
Probably there is a association with the clipped IDs and the error.
Did anyone noticed the same problem?
Here's my code for reconstuction:
vtkClipPolyData *clipper = vtkClipPolyData::New();
clipper -> SetInput(polydata); //polydata is a polydata volume with some
polys and cells
clipper -> SetClipFunction(plane);
clipper -> GenerateClippedOutputOn();
clipper -> SetValue(0.0);
clipper -> Update();
vtkPolyData *clipData = vtkPolyData::New();
clipData -> DeepCopy((vtkDataSet *)clipper ->GetClippedOutput());
clipData -> BuildLinks();
clipData -> Update();
vtkPointLocator *clipDataLoc = vtkPointLocator:New();
clipDataLoc -> SetDataSet(clipData);
clipDataLoc -> Update(); //while updating the data, the error occurs -
sometimes
clipDataLoc -> BuildLocator();
The error message: 'VTKVOMMOON.DLL: 0xC0000005: Access Violation'
Thx in advance, Timo Frenzel.

Hi,
I use Visual C++ created an application with a splitted window. Left
window
contains some buttons and text box. What I expect is that:
when I give some value in the text boxes and click the button, the right
render window will be updated. But now the right window won't be update
unless I click on it.
However,I want to delete a renderwindow,but renwin->Delete(); is useless
among code unless I add it in the front of the function. Else the
renderwindow is not update and exist all along.
Why?
Be eager to your help.

I am writing a windows application using VC++6 and MFC . I wrote the program
base on the vtk window sample program "vtkSDI", and when I need to catch the
mouse click event using classwizard like WM_LBUTTONDOWN, WM_RBUTTONDOWN or
WM_MOUSEMOVE. could there be some suggestion to solve this problem?? I
really need to work this program!
Thanks for your help.
The following is my code,but it does not work.
LRESULT CVtkSDIView::CallInteractor(UINT uMsg, WPARAM wParam, LPARAM lParam)
{
if (this->iren->GetInitialized())
{
return vtkHandleMessage2(this->m_hWnd,uMsg,wParam,lParam,this->iren);
}
return 0;
}
void CVtkSDIView::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
CString msg;
msg="asdsadsadasdsad";
AfxMessageBox(msg);
this->CallInteractor(WM_LBUTTONDOWN,(WPARAM)(UINT)(nFlags),MAKELPARAM((poin
t.x), (point.y)));
}

Hi everybody,
Usually we can rotate an object around its center by clicking mouse using
vtkRenderWindowInteractor.Now I want rotate it at certain angle around its
center.But RotateX,RotateY,RotateZ only rotate it around axes X,Y,Z,not its
center.
How to obtain the center of an object displayed in renderwindow. How to
rotate it around its center?
Help me!!
Thanks

Hey,
how does VTK scale to Terabyte data and over 200 render processes? Is VTK
apropriate for that?
The goal is to visual isoplanes for finite element data. We have no export
filter yet, so we can't just test it. Has someone a tool to create
parallel/partitioned sample data of that size?
Is the scalability different when using Paraview ontop of VTK?
regards
Roland Schulz

To: <vtkusers at vtk.org>

vtkGUI is a free, open source program written in TCL/IncrTCL that was
initially inspired by vtkPipeline and vtkShow. Its purpose is to allow quick
assembly of a VTK pipeline in order to teach/learn/prototype with VTK.
vtkGUI its not meant to do any robust work. However, since it can save VTK
pipelines in both TCL and, to some extent, C++ it can be used as the
starting point for any bigger application.
Features:
- Easily create any VTK Object and connect them to form a pipeline
- Inspect / change any parameter of any created object
- Load / Save as plain TCL script
- Saved files can be executed as stand alone scripts
- Loads "most" of the TCL VTK Examples (see the manual for limitations)
- Export as C++ source code
Authors:
Silvano Imboden (Cineca - Italy): concept, previous version, supervision
Stefan Svensson, Katerina Vrotsou (M.Sc. media technology and engineering
students - Sweden): current release developers
Release notes:
The current release is distributed for Windows only and is provided with an
installation program (40MB). vtkGUI will use it's own embedded versions of
TCL, IncrTCL and VTK so it should run immediately after the installation on
any machine. vtkGUI doesn't use/change any environment variable so it will
not disturb your previous installed TCL and VTK.
In theory vtkGUI should run also on Linux using different versions of VTK,
but the portability has not yet been properly tested. Some hints can be
found in the readme. Any feedback is welcome (mailto vtkgui at cineca.it).
