Hello,
I know this is the sort of question that gets asked
often, and yet I have searched the Cocoabuilder
archives, cocoadev, read the NSCell articles on
stepwise, the docs on NSCell and NSControl (class
descriptions and "Controls and Cells") and can still
not find what I am looking for.
I have a custom view in which I want to click to
create text which can be placed arbitrarily. (This is
actually a margin next to a text view which stores any
number of notes that are aligned with the text.)
Having tried various approaches, I am now trying to
implement this using NSCells.
The problem is, I can find nothing that gives a really
good overview of how to create a custom view that
allows the user to create and edit cells. As a test, I
have tried creating an NSView subclass that draws a
single text cell using drawWithFrame:inView: and
monitors mouseDown:, calling editWithFrame: when there
is a mouseDown event. I can edit text, but I get a
number of drawing issues (if I select text and hit
enter, I just get a blank square).
Are there any good tutorials out there or does anybody
have any experience of doing this that they would be
willing to share? Essentially all I need to know is
how to create, monitor, move and edit a text cell
within a custom view. I know this should be really
simple, but I have found the docs really vague on this
issue.
Many thanks in advance for any help,
Keith
