Issues with GUI mask editor

• New mask is inserted on top of list. Should be at bottom.
• After removing a mask, another mask should be selected.
• Checkboxes "Mask value" and "Show" have no effect.
• on resizing polygon or ellipse mask the view is not updated
• newly created or selected masks do not disappear on pressing "lamp" button. After unselecting data and selecting it back the "lamp" works properly again
• Projection plot does not reflect real state in real time and after creation. Re-selecting data helps

1. Why newly created mask should be at bottom? When user draws a new mask he sees it above existing ones and so that the new drawing should have priority.

Order in list just represents this situation.

Higher in list - higher in canvas - higher in priority.

Otherwise list and canvas will contradict to each other confusing the user.

Agree. In this special context, current behavior is ok.

3. Checkboxes "Mask value" and "Show" have no effect.

There is "no effect" only under certain conditions.

If to unselect data and select again - checkboxes work

Why do we want a "Show" checkbox?

It allows to temporarily turn off the mask without deleting it.

If one wants to try analysis both with and without mask, this may be useful.

Thanks, so I thought: may be useful. OK, let's keep it.

Other question: What is meant by "Mask value"? Inversion?

Yes, inversion. Inverted mask creates a "hole" in the underlying masks.
