Re: NSTextField, drawing the text offset to the right in the field

[Matt Neuburg]

Although, to be clear, you *can* do this is in code, just not the way you
were doing it. You have to make sure you're talking to this instance at the
right moment, i.e. before the window appear but after the instance (the text
field) has been assembled by the nib. That moment, of course, is
awakeFromNib.

So, in awakeFromNib, instantiate the cell (you know, alloc-init etc.) and
set the textfield's cell - not its cell class, its *cell* - to that cell
instance:

[theTextField setCell: theCell];

If you do this in the text field's own awakeFromNib, then *all* text field's
of this class will adopt the custom cell.

[self setCell: theCell];

Or you can do it from elsewhere to specify that just *particular* text
fields should adopt the custom cell.

ahh,  that was it,   thanks a lot,   that made perfect sense once i  
looked inside IB

I was also surprised that IB knew about my custom cell class...

I was thinking code code code...   and i just needed that shove in the  
correct direction...

you made my day,  after a very long day...

thanks,
Jon.

+setCellClass: just tells the view "Hey next time you initialize
yourself, make a cell of this class."  Since your ImageTextField
instance was created inside of IB, this is never going to happen.
Instead you need to change the class of the cell from within IB, under
the Identity inspector.  It might be helpful to switch to the
hierarchical view so you can get easy access to the text field's cell.

Re: NSTextField, drawing the text offset to the right in the field

[jon]

hmmm,  well i'm trying hard to do it...here is what i've done...

in a header:

IBOutlet ImageTextField *addressBar;

i've created this pointer to this instance...

and then in the awakefromNib method,  i have this...

[ImageTextField setCellClass:[ImageTextFieldCell class]];

this set's the class so it's cell is "correct"... for the class...   
but


but maybe this is too late for the instance addressBar.  which was set  
in the header and IB???


I don't know how to check this instance to see if it is using the  
custom cell,   and i don't know how to set the instance  
specifically... (if this class method didn't do it)?

Then you have to *make* the custom textfield use the custom cell. :)  
Use
whips and chains if necessary. Actually, I think what I said before  
may

cover this sufficiently:

As the first part states, an instance of your cell class must *be*  
this text

field instance's cell. You have to make that happen... m.

Re: NSTextField, drawing the text offset to the right in the field

[jon]

i've got something i think is close...

i've got a custom cell,  and a custom textfield,

i've got an override implementation of "drawInteriorWithFrame"  that i  
think will work.


but i'm confused as to where to call "drawInteriorWithFrame",   right  
now it is inside the custom Cell,   but the custom textfield never  
calls it as i believe it should?


right now
---
IBOutlet ImageTextField *addressBar;
---

[addressBar setStringValue:urlString];
is properly using my custom textfield,  but the custom textfield  
doesn't appear to be using the custom cell...  (or atleast the new  
drawInteriorWithFrame is not being called)


(i have not overriden the "setStringValue")  Maybe this isn't the  
right call, and it is bypassing "drawInteriorWithFrame"?


the only connection between custom textfield and the custom cell is

#import "ImageTextFieldCell.h"

 is inside the header of the custom textfield.

does there need to more connection to it?   or how would i get this  
call to the new drawInteriorWithFrame?


the running app shows the text field filled in properly (just not  
offset, as the override implementation of drawInteriorWithFrame would  
have done) ,   so it must have called the super of it somewhere.


thanks for the help in advance.
Jon.

NSTextField, drawing the text offset to the right in the field

[jon]

i've got a textfield defined...

IBOutlet NSTextField *addressBar;

but i don't want to draw the text that is in the field right up  
against the left boarder of the bounding box of this defined field in  
IB,


I want to start the text like 20 pixels to the right of the left  
boarder  and still have the nicely defined frame of the field in it's  
original place...


so far i've tried various methods,   one of them is below

NSRect newFrame = [addressBar bounds];

newFrame.size.width -= 20;
newFrame.origin.x += 20;
[addressBar displayRect:newFrame];

but haven't had any success,  I'm sure someone here knows exactly what  
i'm trying to do and knows a quick way to do it..


i've also tried this:  thinking i could get a textview back into a  
textfield...  or somehow use a textcontainer on NSTextField... with no  
success...


[addressBar setTextContainerInset:theInset];


thanks,
Jon.
