dgHilitedLine

[phaworth]

I think I'm right in saying that if I set the dgHilitedLine of a datagrid in a script it does NOT cause a selectionChanged message to be generated. Is there a way to change that behavior? The selection did change after all.
Thanks,

That is correct and it is the intended behavior. This is how selectionChanged works with list fields as well. The docs for selectionChanged explain that it is a message sent when the user makes a change.

Thanks, just checking if there was a way to change that behavior.

You could define your own custom property in the data grid that does what you want. Something like this in the data grid group script might do the trick:

Code: Select all

setProp myDgHilitedLine pLine
    put the dgHilitedLine of me into theOrigLineNo
    set the dgHilitedLine of me to pLine
    dispatch "selectionChanged" to me with pLine, theOrigLineNo
end myDgHilitedLine

Thanks Trevor, I will try that.

Another thing in your example that is very useful to me is that the selectionChanged message has two parameters when it comes from a datagrid! There's no mention of that in the dictionary, although the dictionary doesn't even mention datagrids in it's description of selectionChanged. I see it does mention it in the Datagrid Manual, I wish I had consulted that insetad of the dictionary!

Thanks,

Yeah, the dictionary doesn't have any info on the Data Grid. You should consult the manual at http://lessons.runrev.com for the latest information.
