[chimerax-users] right mouse zone selection labels

[Tom Goddard]

Hi Sarah,

  Currently there is no setting to adjust the zone mouse mode label colors and text.  You could edit the ChimeraX Python code to change the label colors, that is in 

	ChimeraX.app/Contents/lib/python3.7/site-packages/chimerax/zone/zone.py

You would change lines

        self._label_color = BuiltinColors['yellow']
        self._label_background = BuiltinColors['black']

to the colors you want ('black' and 'white').  There is also no setting for the label text to show chain ID, one letter residue code, and residue number, it only shows 3-letter residue code and residue number.  Even the ChimeraX label command has no setting to adjust this yet.  Our older program Chimera has a labelopt command that allowed setting the text in the label

and we should add something similar in ChimeraX.   I've made an enhancement request to allow setting the default colors and text.

You are right that the preference setting Labels / Balloon-help Specifier Style will not effect what the Zone mouse mode labels show.

However, the default labels are black background and yellow text, and only the residue 3 letter code and number. Is it possible to change these labels to a white bg and customise the labels to include e.g. the one letter code and chain ID? I tried to do this with the selection - labels tool but it did not seem to change it for the zone labels.
