Suite and Optimus Suite 5
#1

When the user drags and drop a note we catch the event ( tondrag() )and
right there we display a dialog box (IFRAME) where we need to capture some data
from the user and run some validations. Depending on the outcome of this we
will allow/deny the drag and drop operation (returning true/false).

The problem we’re facing is that we have no way of having the tondrag()
wait until the user finishes interacting with the IFRAME and as you probably
know javascript doesn’t give you a lot of mechanisms to put the parent window’s
thread to sleep while the IFRAME keeps executing.

Anyway, one way to solve this would be to return false in the handler
but then be able to programmatically invoke the event once more once we know
the result of the user interaction with the IFRAME.

Is this possible with the tool or what other approaches
do you suggest?

Yes
it’s possible. The tree has moveItem command which fully imitates the onDrag
event (basically it gives even more possibilities than standard d-n-d). It uses
all drag-n-drop settings, and fires onDrag and onDrop events as well.

Please
refer to samples/pro_move_item.html

 
Also
the latest build of the tree supports lockTree command which blocks any
interaction with tree - it is useful to prevent firing of any new actions while
processing your form.

If you’re designing only for IE, it supports “modal dialogs” -
which are kind of popup windows, which suspend javascript in main window, while
popup will not be closed
