Pushed new branch T19683-ShowOnlySelectedNodesSecondLevel.

Yes, unfortunately the current solution only works for first level.

It has been resolved in branch T26630-AccessAugmParams

If you ask for all the nodes from data storage then you get also child nodes in random order. In the previous implementation, visibility of all child nodes of widgets are set to True when the widgets node is reached. Nonetheless, child nodes visibility were afterwards set to False in the outer loop.
Now the loop is only done on nodes in the first level that contain data, therefore crosshair nodes stay always visible.

In Ubuntu 18.04 data storage is accessed in random order therefore the visibility of crosshair was set randomly. Fixed in branch: T19683-ShowOnlySelectedNodesCrosshairVisibility-RandomAccess.

Pushed new branch T19683-ShowOnlySelectedNodesCrosshairVisibility-RandomAccess.

Through merge conflicts.. The baserenderer argument was added in the master.

Which 2 actions?

@floca This is the branch T26029-4DImageAnd4DSegmentation

I merged it, we only pushed the branch

I couldn't reproduce it. @kleina Can you? (maybe it occurred only due to missing reinit?)

We reverted the changes according to your concerns. Instead of creating a new ImageStatisticsObject in the GetStatisticsForTimeStep method, we now check whether the time step exists before calling the method. That fixed the problem. Statistics are now only shown for the time steps that have a segmentation associated with.

There seems to be another exception thrown when willing the table view. The statistics table is not filled. The idea is now not to change the GetStatisticsForTimeStep functionality but handle the exception in the level above (like we started before with the try-catch)

Pushed new branch T19683-ShowOnlySelectedNodesCrosshairVisibility.

Solution: GetStatisticsForTimeStep method now returns an empty StatisticsObject if no mask is provided for this time step. Thus, histogram and table are empty for those time steps.
Discussion: 1. 4D image + 3D segmentation

2. 4D image (5 time steps) + 4D segmentation (1 time step)

@hentsch Is the one time step segmentation applied to all time steps? What is the expected behavior?

Pushed new branch T26276-SegmentationMultipleTimePoints.

Statistics are calculated for those time steps where a mask is provided, for the others not. When the view asks for the statistics an exception is thrown if the statistics don't exist.
