Refreshing form after modal update?

[Bill Walker]

Hello Group,

Proceeding thru the 'Learning Action Scripting' book I came to the section that shows how to update a record using a form opened in modal mode.

The book said that after closing the update form that the form should display the updated record. Mine did not update the record so I tried making the update form modeless and after closing the update form the form did update using the 'OnActivate' event to do a form refresh.

I used the trace window to try to figure out why the 'OnActivate' event would not refresh the from using the modal update form and to my surprise the 'OnActivate' event does not get triggered after returning from a modal form.

How do I update(refresh) the form if no event is triggered when returning from a modal form?

I have an example attached, startup form will display problem.

Thanks for any direction,
Bill

I am having the same experience as Bill did in January. I am very disappointed that no one (not even at Alpha) ever responded to this. Here is my situation.

I have a button on a form that calls a series of modal forms after which it returns to the original form. I have a script in the OnActivate event that will take all the modal input into account and take action appropriately. Only one problem - it never fires when focus returns to the form. If I click on another window (say the Control Panel) and then back to the form, the OnActivate event fires, but not when focus returns from modal forms used as dialogs.

Anyone else experience this or know how to fix it???

It is true that when a button on form opens another MODAL form, then OnActivate event on the parent form does not fire.

personally, i think it should fire. but it does not, and it is not likely that we will change this behaviour in the short term because doing so would break a lot of other things.

in any event, the solution to the problem is easy.

just add a new step to your script after the command that opens the modal form. the command is the same as the command that you have on the form's OnActivate event.

e.g.
the "Refresh Layout" command, or if you prefer xbasic
topparent.refresh_layout()


the reason that you had to put this in the onActivate event in the case of a modeless form is that in this case, any code you put in the script after the code that opened the form would execute immediately - i.e. xbasic would not pause to wait till you closed the new form since that form was modeless.

Essentially what Selwyn is saying is that if you put a script on a button on a form that calls a MODAL form, the script pauses until the modal(s) are complete and focus returns to the form that originally called the MODAL form or forms. Pretty cool!
