Just a little titbit we have recently learnt that might be useful for
the list.
In our conversion from Display Manager to FoxView we have noticed that
some buttons on overlays stopped functioning correctly. This turned out
to be because of a subtle feature in Display Manager that appears not to
be supported in Foxview.
As most will be aware, one can only assign 1 action to any graphic
element. This is not usually a problem as one can use the DM Command
action to perform a number of dmcmd commands. Unfortunately there is no
dmcmd command for the Momentary Contact action.
Our problem was that, in Display Manager, we configured most of our
buttons on overlays to have "DM Command" actions such that when the
button is pressed two things happen: the command is executed and the
overlay is closed.
For the case of a momentary contact action, we got around the 1-action
limitation by configuring the button with two rectangles, each with its
own action. One of the rectangles was assigned the Momentary Contact
action and was given a name (Ack say). The other rectangle was assigned
a DM command and performed two actions:
dmcmd pick Ack
dmcmd close
Now the crux: this does not work in FoxView.
Our initial solution was to provide an extra "OK" button to close the
overlay. However a colleague came up with a better solution.
Given the various elements of the button are grouped, our solution was
to assign the momentary contact to the Group (rather than a rectangle)
and assign the close command to the rectangle. For some reason, when
it's assigned in a vertical hierarchy it seemed to work.
Hope this helps someone, or leads to a better solution from someone
else.
