How to add an image cell without IB? (Easy Newbie Question)

Scripting Forums AppleScript Studio & Xcode
#1

Is there a way to add an image cell column to a table outside of using IB? I’m trying FaceSpan, and I can’t figure out how to set it up in that program. In IB we can draw one into a table column, but that option does not exist in FaceSpan (as far as I can tell).

So I am asking here because I would like to know how IB sets the Image Cell (or Text Field Cell) up in Cocoa. Then maybe I can set this up myself maybe in my FS project. FS is just easier to learn on, I think, and I’ve gotten alot farther on my app using it. This is the one hurdle I have to overcome for now… why didn’t they just add the draggable option like AS Studio… grrrr…

Thanks guys,

Hi :slight_smile:

Unfortunately, to my knowledge, AS-Studio does not allow, by default, to create objects dynamically by the code.
It is perhaps possible to do that by using the Obj-C methods, but I do not control absolutely these techniques for the moment.

As for FaceSpan, I think that its possibilities are for the moment much more reduced on the matter than AS-Studio, but, there too, I am not a sufficiently expert to deliver a sure opinion.

Sorry not to better be able to help you.

:wink:

Thanks, Fredo.

The learning curve for this can be pretty difficult to overcome. It’s hard to find solid info sometimes. I signed up at VTC.com and went through their AppleScript 2006 and Applescript Studio courses (about 16 hours total I think), and I learned alot, but much of this is still a total mystery. Once I hit the Cocoa wall I get in trouble. Looks like I’ll have to take the C programming course…

There must be a way to get this to work…

Hi Doug,

sorry - I have absolutely no idea what’s possible with FaceSpan and what’s not - I have never used it … but for adding a Table column with ImageCells programmatically I might give you some help.
As Fredo alredy said - it is not possible from AppleScript - you need a little Objective-C for this.

Here a first (quick&dirty) attempt:

just add a new Objective-C class file to your project and edit … .h/… .m like so:

//  TableViewAdditions.h

#import <Cocoa/Cocoa.h>

@interface NSTableView (TableViewAdditions) 
-(void)addColumnWithIdentifier:(NSString *)identifier width:(float)theWidth cellType:(int)cell;

@end

//  TableViewAdditions.m

#import "TableViewAdditions.h"

@implementation NSTableView (TableViewAdditions)

-(void)addColumnWithIdentifier:(NSString *)identifier width:(float)theWidth cellType:(int)cell{
	NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
	NSTableColumn *newColumn = [[NSTableColumn alloc] initWithIdentifier:identifier];
	[newColumn setWidth];
	switch (cell) {
	case 1:
		[newColumn setDataCell:[[NSTextFieldCell alloc] init]];
		break;
	case 2:
		[newColumn setDataCell:[[NSImageCell alloc] init]];
		break;
	case 3:
		[newColumn setDataCell:[[NSButtonCell alloc] init]];
		break;
	default:
		break;
	}
	[self addTableColumn:newColumn];
	[pool release];
}
@end

now it should be possible to create new table columns from your applescript with:


tell (table view "tv" of scroll view "sv" of window "main")
	set theIdentifier to "pictures"
	set columnWidth to 50.0
	set cellType to 2 -- 1= textfield cell, 2 = image cell, 3 = button cell
	call method "addColumnWithIdentifier:width:cellType:" of it with parameters {theIdentifier, columnWidth, cellType}
end tell

D.

Nice! Thank you SO much for the guidance. I’ll try it tonight…
