Question

In my Browser implementation to select default rows I have used the following code.

[browser setTarget:self];
[browser setAction:@selector(singleClickOnBrowser:)];
[browser sendActionOn:NSLeftMouseDown];
[browser selectRow:0 inColumn:0];
[browser sendAction];

Is there any way to differentiate user click and the rows selected for the first time to select default rows?

Answer 1

I did not find any API to differentiate user click and selecting the rows and columns from code. To achieve this I declared a BOOL variable to keep track of user clicks.

Following Code I changed the BOOL variable in Code.

self.userClickedOnRow = NO;
        [self.browser selectRow:0 inColumn:0];
    [self.browser sendAction];
        self.userClickedOnRow = YES;

Implemented the following delegate

 - (void)browser:(NSBrowser *)browser didChangeLastColumn:(NSInteger)oldLastColumn toColumn:(NSInteger)column
    {

        if(!self.userClickedOnRow)
        {
            NSLog(@"Programatic selection");
        }
        if (self.userClickedOnRow)  
        {
            self.userClickedOnRow = NO;
            // User Clicked on the browser,Do the required actions and set the variable again.
            self.userClickedOnRow = YES;

}
}
