What I would like to do is to update a listview (in my package) after I click
on the source editor. So I need to hook into the source editor's OnClick method

two items will probably be more easy, but what about the first? Is there an
interface for the code tools that allows this? How about hooking into the
OnClick method of the source editor?
Well first, you need to be aware, that SourceEditors (SynEdit), and
SourceNotebook(s) ( the windows in which they are) can come and fo.
Your start-point is TSourceEditorManagerInterface in
ideintf\srceditorintf.pas
procedure RegisterChangeEvent(AReason: TsemChangeReason; AHandler:
TNotifyEvent); virtual; abstract;
procedure UnRegisterChangeEvent(AReason: TsemChangeReason;
AHandler: TNotifyEvent); virtual; abstract;
To allow you keep track of them.
Be aware "semEditorStatus" will fire a hell lot. not the best Idea to
use it. (it will fire on every caret move for example); unfortunately
not on click (unless the click moves the caret, but that isn't always
the case. => For status change, it is better to register with synedit
direct, since you can give synedit a filter, and reduce the amount of
calls, to what you need.
Since SynEdit's on click will already be hooked, that want be easy....
Actually, just seen it isn't; but it could any day.
You could register your own mouse action with SynEdit, but that's rather
complex too.
It would be enough to register a proc with
SynEdit.RegisterMouseActionSearchHandler, or
TSynEditMouseActionExecProc. It would receive the mouse info, but could
just do nothing (unless you want to abort the current action.
However:
- I am not 100% sure that will stay exactly as it is. e.g in user land
synedit this may become an optional handler. in the IDE it is 99.99%
likely to stay as it is.
- There is no grantee on the calling order, other handlers could return
true first, and yours would not be called

At this point I noticed your next post.
RegisterStatusChangedHandler in synedit => see what fpdoc edit does
