Hello Cocoa List,
My Googling reveals this question has been asked before, but no answer
was given. Hopefully someone knows how to do this now.
I have a vertical NSRulerView attached to an NSTextView. I have
movable NSRulerMarkers and that's all working good. My only problem
is that the NSRulerMarkers insist on displaying a tooltip with the
current measurement values when the marker is being dragged. This is
not appropriate in my application. Ideally, I would like to suppress
these tooltips.
I have tried intercepting various things in my NSRulerView subclass.
These typically didn't work because the ruler view doesn't seem to be
responsible for the generation of the tooltips. NSRulerMarker doesn't
seem to have functionality to do this, and doesn't inherit from NSView
either.
Another way to manage this might be to provide a dynamic measurement
unit. My markers are essentially pointers into the text, and really
are indicating specific line numbers, like break points. Dynamic
measurements would be necessary because the font of the TextView can
be set by the user, and where the marker is pointing will then depend
on the font size. There doesn't seem to be a way to do this either.
Is there something I'm missing? Surely this is something someone has
attempted before?
Thanks in advance,
Arved
