I'll rephrase my question about "text thingys":
I want to be able to create at run-time a window which contains a
scrollable array of NSTextFields, scrollable because there may be more
text fields than will fit in the visible part of the window.
Each text field has a display rectangle, within which can be entered
(and displayed) a single line of text (with attributes).
If the window has focus, then a mouse-click within one of the text
fields should invoke a method (presumably via delegation or
notification) with an arg that tells the method which text field was
clicked in.
Is that possible?
I haven't been able to get that to work, even though aNSTextField
seems (like an NSButton) to be a subclass of NSControl, and to have
(again like NSButton) an associated cell class (NSTextFieldCell) which
is a subclass of NSActionCell.
I have been able to get this to work with NSButtons rather than
NSTextFields, but that seems -- gross.
Assuming you have some kind of controller object that would
respond to delegate messages from the text fields:
o create your text fields programmatically,
o assign each created field a unique tag using the -setTag
method
o make your controller object the delegate of the text field
using the –setDelegate method
o implement the -controlTextDidBeginEditing method defined
in NSControl.
o look into the other delegate methods as appropriate, and also
look into -setTarget and -setAction methods.
