Custom table view column - problems with completing

[alex7]

I was looking for way to have different cell classes in the same column of table view. I’ve found solution - to override dataCellForRow() of NSTableColumn.
So I’ve added new class to my project -
TableColumnAdditions.h

#import <Cocoa/Cocoa.h>

@interface NSTableColumn (TableColumnAdditions)
-(id)dataCellForRow:(int)row;

@end

TableColumnAdditions.m like this

#import “TableColumnAdditions.h”

@implementation TableColumnAdditions

-(id)dataCellForRow:(int)row{
if (row < 0) {
// OS wants generic cell information
return ([self dataCell]) ;
}
if (row == 2) {
id textCell = [[NSPopUpButtonCell alloc] init];
return textCell;
} else {
id textCell = [[NSTextFieldCell alloc] init];
return textCell;
}
}
@end

But I’m wondering on two issues -
1st) Xcode shows two warnings at .h file:

#import “TableColumnAdditions.h”

@implementation TableColumnAdditions

-(id)dataCellForRow:(int)row{
warning: cannot find interface declaration for ‘TableColumnAdditions’
if (row < 0) {
// OS wants generic cell information
return ([self dataCell]) ;
warning: ‘TableColumnAdditions’ may not respond to ‘-dataCell’
warning: (Messages without a matching method signature
}
if (row == 2) {
id textCell = [[NSPopUpButtonCell alloc] init];
return textCell;
} else {
id textCell = [[NSTextFieldCell alloc] init];
return textCell;
}
}
@end

Can’t figure what I’m doing wrong?

2nd) Can’t figure where to override column class in my script. Let it be simple script like this:

	set theTV to table view "tasks" of scroll view "view" of window "main"
	
	set theDS to make new data source at end of data sources
	set col1 to make new data column at end of data columns of theDS with properties {name:"name"}
	set col2 to make new data column at end of data columns of theDS with properties {name:"value"}
	set theRow to make new data row at end of data rows of theDS
	set content of data cell "name" of theRow to "Option 1"
	set content of data cell "value" of theRow to "Text"
	set theRow to make new data row at end of data rows of theDS
	set content of data cell "name" of theRow to "Option 2"
	set contents of data cell "value" of theRow to {"Yes", "No"}

Thanks for help in advance. Hope I’m using right place ( I mean AppleScript Studio & Xcode).

I think you need to put the Parent Object class name on the End and the custom class name first.

@interface  TableColumnAdditions : NSTableColumn

As to question 2, I think you need to make a call Method to create a instance of you new class.

I am just learning Objective - c, so have not bothered to learn about using call methods for ASS.

Search in " AppleScript Studio & Xcode " the for call Method and maybe also sub class.
