Question

So i’ve a class “mainpercentage.m”, and I want one variable in that class assume a value of ComboBox index. I’ve tried method “indexOfSelectedItem”, but I can not understand the syntax.
Thank’s for help!

Mainpercentage.m:

@implementation MainPercentage
- (IBAction)SetPercentage:(id)sender {
/*

Here I want get index of my ComboBox

*/
    if (1==1) {
        [pryam setIntValue:40]; //pryam- FormCell
        [razb setIntValue:30];
        [estestv setIntValue:30];
    }

}

- (IBAction)GetKon:(id)sender {

}
@end

Mainpercentage.h:
#import <Cocoa/Cocoa.h>

@interface MainPercentage : NSObject {
    IBOutlet id estestv;
    IBOutlet id pryam;
    IBOutlet id razb;
}
- (IBAction)SetPercentage:(id)sender;
@end

From the docs:

- (NSInteger)indexOfSelectedItem

So if you have an NSComboBox, let’s call it myCombo, you would say this:

NSInteger indexInteger = [myCombo indexOfSelectedItem];

Now indexInteger is an NSInteger whose value is the index.
