Have Render By Attribute externally controllable

[Tom Goddard]

Allow other code to bring up Render By Attribute showing desired attribute/colors/etc.

I added structure coloring controls to the mutation scatter plot gui yesterday that attempts to setup the Render by Attribute GUI (residues, specific structures, mutation score attribute, palette and levels). I used private methods of render by attribute in scatter plot function _show_render_by_attribute_gui() in code

chimerax/src/bundles/mutation_scores/src/ms_scatter_plot.py

It is not quite working because setting the render by attribute models causes a delayed callback that overwrites my render by attribute palette setting. So using a public API to set the render by attribute gui controls would be helpful.

The mutation scores scatter plot use of render by attribute is part of ticket #19403.

By "palette" do you literally mean a palette name, or do you mean a series of color values?

[Tom Goddard]

I meant color values and specified color levels.

The Render/Select By Attribute tool now has a configure() method. I hope the method's doc string does a good enough job of explaining how it's used.

[Tom Goddard]

The level_info argument of the RenderByAttrTool.configure() method does not show the requested levels in the GUI. Instead it appears to set the default levels. I tested this with the MutationScatterPlot tool and I have code in that tool (ms_scatter_plot.py) commented out. That is probably not the easiest way to test since it requires mutation score data.

Another option that the MutationScatterPlot tool wants to set is the no value color and the no value checkbutton. That is not currently settable by the configure() function.

Fixed the color-configuration issue (worked if no 'models' were specified, but not if they were): ​https://github.com/RBVI/ChimeraX/commit/9b513971a3b0f752c4ddfe914710836ecbfb1996

Working on no-color configuration now.

Okay, you can configure the no-value controls via the no_value_info keyword, which takes a two-tuple/list consisting of a boolean and a value. The boolean controls whether the checkbox is checked.
