Hello again Kalali,
I came back with this issue. Exactly as you had expected, I found problems
with my solution of having two specific rendering managers in two different
QmitkStdMultiWidget, when I integrated the Segmentation module into the
app, I found that it updates the renders using the global rendering
manager, and thus it didn't update my "specific" render windows... it
updated the windows but after a while, not in real time.
So, I deeply looked into your last responses... You suggested me to have
one global rendering manager and initialize the view of each renderer
window in one of your StdMultiWidget with the given bounds. As you said "This
will allow you to do the InitializeView only for those render windows in
StdMultiWidget1 where DataStorage1 is valid and InitializeView differently
for those render windows in StdMultiWidget2 where DataStorage2 is valid."
I did exactly this (you can find the code below), however it does not work.
It seems that even if I use InitializeView in one StdMultiWidget and its
DataStorage then it applies the same geometry to the other StdMultiWidget
and its DataStorage... I don't understand why...
I also had a deep look at the RenderWindowManager Plugin (and module) and I
was not able to achieve what I want.
Workbench Example: I load a MRI, a US and a US_Doppler images to the
Workbench. I would like to show in the differnet renders:
- In the red (Axial) render: US axial view
- In the green (Sagittal) render: US_Doppler axial view
- In the blue (coronal) render: MRI axial view
By using RenderWindowManagerPlugin I was able to place each image in each
render, however if US images are shown (which are similar in geometry), I
can't see the MRI image. So I do a MRI Node Reinit and MRI is shown but not
the US images... I am not able to see all of them together at the same time!
Is there any way to solve this? or what would be the direction?
Any inspiration would be very helpful!
Thank you very much in advance,
Best regards,
Rocío
