<br>
I have written a vtk-programm that allows me to display a 3D data set (VTK<br>
and QT). Additonally you can interact with the 3D Data with<br>
'RightButtonPressEvent' and 'MiddleButtonPressEvent'. Both interaction are<br>
point picker interactions.<br>
<br>
My problem is, that for example, when I press the 'RightButton' two things<br>
happen at once:<br>
<br>
1. Point on 3D Data get's picked<br>
2. Camera is zooming in/out (only when I move mouse during picking, but this<br>
happens from time to time)<br>
<br>
The same happens with 'MiddleButtonPressEvent', the objects just get moved<br>
instead.<br>
<br>
So basically I want a button on my GUI, where I can choose:<br>
1. Either Zoom in/out<br>
2. or pick a point<br>
<br>
As an alternative I would be satisfied with something like this:<br>
1. Just OnLeftButtonDown() -> Just Zoom/Pan/Spin<br>
2. OnLeftButtonDown() + KeePressEvent -> Don't zoom, pick point instead<br>
<br>
This is how I implemented the 'MiddleButtonPressEventHandling' by now:<br>
<br>
<br>
<br>
I know, this is not the best way, but it worked so far. I propably will<br>
implement it this way in the near future:<br>

<br>
But even when I use the MouseEventsObserver I still have no Idea how<br>
suppress the Zoom/Pan/Spin Events...<br>
<br>
Than I thought of this method instead:<br>

<br>
First of all, I don't need (and also don't want) all the features of the<br>
vtkInteractorStyle class like Keypressevents for p, r, s, u, v e (as you can<br>
find them here:<br>
<a href="http://www.vtk.org/doc/nightly/html/classvtkInteractorStyle.html" target="_blank">http://www.vtk.org/doc/nightly/html/classvtkInteractorStyle.html</a> at Detailed<br>
Description)<br>
<br>
I just need to overwrite 'OnLeftButtonDown', 'OnMiddleButtonDown',<br>
'OnRightButtonDown' etc.<br>
<br>
So basically I tried things like this, but they don't work, of course:<br>
<br>
<br>
<br>
<br>
Honestly I have no idea how to solve my problem... I also haven't found much<br>
documentary besides the examples.<br>
<br>
Thank you for your help, I really appreciate it<br>
