Back story.
If you browse Category 'Kernel-Methods' class CompiledMethod and right click on 'accessing-pragmas & properties' then select 'browse' a Browser appears showing all the methods in that method category;
In some HelpTopic work I am doing, I want to do the same thing within the HelpTopic so the user can do a DoIt and see all the related methods I am discussing.
I hunted around for how the system currently does it and Browser->buildMessageCategoryBrowserEditString: aString does the work.
I am able to duplicate that with
Browser openBrowserView:(
(Browser new)
selectSystemCategory: #'Kernel-Methods';
selectClass: CompiledMethod;
metaClassIndicated: false;
selectMessageCategoryNamed: #'accessing-pragmas & properties';
selectMessageNamed: nil;
openMessageCatEditString:nil)
label: 'Message Category Browser (', #'Kernel-Classes' asString, ')'.
