OnRowDblClick fires when?

[russ Boehle]

The manual Programming with xbasic says for OnRowDblClick: " When you double click on a row selector. If the browse object is read only, then this event will fire if you double click within the row."

I am finding that this fires whether the browse object is read only or not. Is there any way to make this event ONLY fire when the column is read only, not all the time.

I suspect that the answer to this is wait for v6 but thought I'd ask anyway. I would like different behaviour with OnRowDblClick depending on whether the column is read only or not.

Thanks

This is not, I believe, a bug but is the behavior that OnRowDblClick is supposed to display. I think that the documentation just points out that the browse event still fires even when the browse is read-only. Perhaps a better way of wording it would be

" When you double click on a row selector. If the browse object is read only, this event will still fire if you double click within the row."

Thanks Peter,
Oh well. I was hoping for a way to get different behaviour with different columns. I guess I can't do this now. Hopefully this will be in v6.

This is part of trying to print marked records from an embedded browse, but I'll do another post for that as it's a different topic.

thanks again

You can certainly code the browse's OnRowDblClick event to see if the browse is read-only. e.g.

if this.browse.readonly=.t. then
' do something if the browse is in readonly mode
else
' do something else if the browse is not in readonly mode
end if

Yes, this is true, but correct me if I'm wrong, but I don't think I can do it by column. Unless I can test for if the mouse cursor is in a column, I haven't tried that. I guess I should before saying it can't be done.

You can trap a double click for a specific field by using object properties. If you open the object explorer with the form in design mode, yoy can access a variety of porperties that might fit you needs. Apparently, you want to disable double click if a field is read only. For instance, if you have set a column property for a field called "price" in a browse named "browse1" to readonly, the property in xbasic would be:

topparent:Browse1:Price.Field.Readonly = .T.

You can test for this in the double click event and cancel the event if the property is true. Of course the next question is how to trap which field has focus when you double click. You must test for the active object. This will give the name of the active browse object for "browse1"

topparent:browse1.active()

To put it all together into an expression to test the active object for read only, use eval() and get this:

if eval("topparent:browse1."+alltrim(topparent:browse1.active())+".Field.Readonly") = .T.
end
end if

If this is at the beginning of the OnRowDblClk event, the event will only fire if that column is not read only.

Thanks Jerry,
That's great. What I will do is modify this so I can have different actions depending on what field is doubleclicked on. This should give me the versatility I need.

Thanks again,
