How to use Browse "event"

Re: How to use Browse "event"

Well Martin I havent tried that. Off the top of my head I would try a number of backspaces (which I dont know off the top of my head HOW to do yet -until I needed to)
and I would consider trying to see if a set focus could work.
I'm not as familair with those options perhaps as you probably are. I will play around but if you make any progress please post back.
I just wanted to show how I have applied some actions to a browse field change and to stimulate some other uses.

Re: How to use Browse "event"

This simple method works Martin
Good suggestion - it looks really slick. Just pops back into the required field in the row, already in edit mode (with "E" switch).
In this test it goes to the defaulting lnqty field

function lncandisc_OnChange as v ()
if browse1:lnqty.value=0
	pb=obj("browse1")
	pb.Home()
	while pb.active() != "LNQTY"
	  pb.Right()
	end while
	pb.Activate("E")
	end
end if
end function

In fact only one line is all that is needed using the field's property

if browse1:lnqty.value=0
	pb=obj("browse1")
[B]	pb.lnqty.activate("E") '<<<<<-----
[/B]	end
end if

Re: How to use Browse "event"

unfortunately, it doesn't work for me

I made a test adb and put the code in the events for the embedded browse

if I enter or tab past the field, nothing happens (most likely because I am not "changing" anything)
if I change the field to a value like 10, then it traps the "prior" value
what is needed is can events

if you have several fields in your test adb, enter a new row and just enter or tab through it and see what happens

Correct, there are not can events for at the browse level..

But there are can field events at the field rule level...

ie:
caneditfield.png

so check and see if this fires when you want and add your code there... Probably need to test if the proper field is available as an object...

Re: How to use Browse "event"

I'm confused Martin
How do you trigger a can event without change?
If you want to force a field to be non zero it has to be changed. A field rule can simply enforce a value to be entered, no?

Re: How to use Browse "event"

well ... in field rules, in the caneditfield event for the table, at the tare_weight field you can say

t=table.current()
if t.gross_weight=0
	sys_send_keys("{left}")
	busy=.f.
	end 
end if

so ... if they arrive at the tare_weight field, and they skipped the gross_weight field, if will automatically go back to the gross_weight field.

I've been using this approach for quite some time, but was trying to find an additional method.

Re: How to use Browse "event"

Excellent, thanks for that.
I was thinking otherwise that level of control (ie just landing on a row field) would have to be done with xdialog
or fast timer checking current object - very clutzy
