Re: Detecting clicks in a DataBrowser

Larry,

I want to have a column of icons in a DataBrowser in which no items are

selectable, but I want to be able to detect clicks in the icons. AFICT there

is no notification sent when this happens (duh). Any suggestions? Thanks,



The only way I have found to do this is to install a click handler on the DB control as a whole, and then loop through all the items, and then loop through all the properties, getting their enclosing rect and testing against that. As you are only interested in the one property then you can skip the property loop.

You could also work around this using a custom column or columns, and drawing them yourself. You could then make them selectable, but never draw them as selected, and use the custom hit testing call back.

What we really need is

DataBrowserItemID GetDataBrowserItemAtPoint( ControlRef browser, const Point point, DataBrowserPropertyID *property );

and, when I get enough spare moments I will file enhancement requests for this and many others.

Douglas
