[chimera-dev] Get values from other chimera dialogs

Hello everyone! I feel you will get tired of me asking so many questions hehe Anyway, I continue developing my plugin and I'd like to know if there's any way to get values from other chimera dialogs although they are not open. For example, when my map is loaded I need the values, from the Volume Viewer, of the voxel size (in Coordinates panel) and the cutoff, but I didn't find how to get them and I really don't know if this is possible or not. Thank you in advance and, as usual, kind regards! Pablo.
