How to programmatically select a datagrid

[CAsba]

HI all,
I have three dg's on a card. I can select a dg by clicking on it and then using up and down arrows to select a line. But, I want to enable the user to use the keyboard instead of the mouse. Is it possible to programmatically 'click' on the dg to enable the user to use the up and down keys ?

Hi,

You could

Code: Select all

click at the loc of grp "yourDatagrid".

.
That would focus on the DG you want. But once you get there, how do you navigate to the "cell" or row you are interested in? Something like:

Code: Select all

   click at the loc of fld "col 1 0002" of grp "yourDatagrid"
   click at the loc of fld "col 1 0002" of grp "yourDatagrid"

That will at least get you to the second row. I bet if you played around a bit, you could get to a particular field, in the same way as if you double-clicked on that field.

Obviously I am no expert with DG's, though I do use them now and then.

See the dgHilitedLines property.

Many thanks.

A problem. Although something like:

Code: Select all

set the DGHilitedLines of grp 1 to 3

works fine, it does not "select" the DG itself.That means that the arrowKeys are not able to do any navigation. Clicking on a line in the DG does.

If he doesn't want the user to have to click on an object he wants to have focus, he'll have to handle events at the card or stack level and set the focus in response to the arrow key handler there.

The focus can be set with the "focus" command.

Setting the focus of a DG does not, er, focus it. In fact, if I have a card with a single field, focussing on it:

Code: Select all

focus on fld 1

does not do what the dictionary says it does, which to, er, focus on it and place a blinking cursor there. I have to click on the field to do that.

I never use the focus command. This may be a good reason to still not.

AHA.

It does work from a button, just not from the message box. I see a short-lived "blink" in the fld from msg, but nothing changes.

Focusing and selecting are two different things.

I usually do this as a combo something like:

Code: Select all

focus on fld 1
select char -1 to -1 of fld 1

I'm usually doing that with list fields so..

Code: Select all

select line 1 of fld 1

The Datagid is different animal, a library / template stack with groups thing, so I think you would need to add to the chunk expression with something like 'select char tMyCharPosition+1 of fld 1 of group tMyDataGrid'.

I definitely have a working example somewhere, of a Datagrid that's entirely navigable from a keyboard, arrowKeys, tabKey etc. I'll try to dig it out and post it if I get a minute.
