Re: Drag group

[Ryno Swart]

Thanks for the help, Scott and Monte,

I'm getting there. However, the mouseMoves you kindly suggested work well with an object such as a button, while not seeing or treating a group as an object.

As I have exactly the effect I want, the simplest for me is to show you where I am now (having turned Scott's drag_sample stack around a bit). I created a long flat graphic. In it I placed 7 buttons, named Drag me and 2, 3, 4, 5, 6, and 7. These make up the group I would like to drag. I made the group wider than the graphic.

So far, the script for this group is

on mouseDown
set the uAllowDrag of me to \
the mouseH - left of me & "," &\
the mouseV - top of me
set the uAllowDrag of me to true
end mouseDown

on mouseMove x,y
if not the uAllowDrag of me then exit mouseMove
put width of me/2 into W
put height of me/2 into H
set the loc of me to \
min(left of grc Viewfinder+W, max(x,right of grc Viewfinder-W)),\
min(bottom of grc Viewfinder-H,max(y,top of grc Viewfinder+H))
end mouseMove

on mouseUp
set the uAllowDrag of me to empty
end mouseUp

and it all works exactly as I want, except that while I can click on any button, the moment I move the mouse, it is always over no 4. If, as I hope to do I have about 20 images in his group, I fear that I will not be able to drag all the way to the images furthest from the centre one. This is why I need to make the mouse grasp the button that it goes down onto, and drag the group from this position. I know that there may be other solutions, such as working with a scroll bar, but this is just so beautiful!

Can it be made perfect as well?

Much inspiration,

Ryno.
