<p class="MsoNormal"><span style="font-size: 10pt;">Hello VTK users,</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">I am still fairly new to VTK, so please forgive my (likely) noob question…</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">I have several QVTKWidgets on screen at one time (some showing 2D slices, some showing a 3D volume). I would like to add an interactor to these widgets so that the 2D slice
viewers will scroll through the slices with the mouse wheel, the 3D volume viewer will roll/rotate with a mouse click/drag, and both 2D and 3D have the capability to adjust window/level and zooming via some mouse movement (doesn’t matter how). Scrolling and
window/level modifications are already available through sliders on the GUI.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">My question is, do interactors already exist that do this sort of thing? Or is this something I must write custom?</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">Thanks,</span></p>
