I need to build a UI similar to the Finder or Windows Explorer, in which
there are icons that can be moved around, and selecting one brings it in
front of the others. To drag you just click and drag of course, and the
icon first come to the front then does the dragging action.
These icons are in a scrolling group, the Chipp's thread here last month
on relayering controls was very helpful.
But I've run into a snag: I move the object to the top of its group on
mouseDown, and then set my vars needed to handle the dragging so they
can be used later in mouseMove. The mouseMove stuff works okay, but I
never get a mouseUp or mouseRelease to empty my dragging flag. :\
Here's my code - the "put the params" statements in the mouseUp and
mouseRelease handlers don't fire:
local sIsDragging, xOff, yOff
on mousedown
lock screen
start editing grp "Main"
set the layer of me to top
stop editing
unlock screen
--
wait 0 with messages
put true into sIsDragging
put the mouseH-the left of me into xOff
put the mouseV - the top of me into yOff
end mousedown
on mouseMove x,y
if sIsDragging is true then
set the topleft of me to (x-xOff),(y-yOff)
end if
pass mouseMove
end mouseMove
on mouseUp
put the params
put empty into sIsDragging
end mouseUp
on mouseRelease
put the params
put empty into sIsDragging
end mouseRelease
Am I missing something here, or does editing the background muck with
some relationship between the target and mouse messages?
