Cursor during image movement?

I'm trying to move an image based on the mouse, as long as it's "down". I cannot use the
Grab command because the image to be moved is not at the mouse location.
The following script works but I would like the cursor to be a
cross during the movement, and it does not work: the cursor blinks from time to time during the movement but remains mainly in
arrow.
Any idea?
Code: Select all
global PXCROP_ISMOVING
local gDeltaH, gDeltaV
on mouseDown
put true into PXCROP_ISMOVING
set cursor to cross ////////
show img "ImgToMove"
put (item 1 of the loc of img "ImgToMove") - the mouseH into gDeltaH
put (item 2 of the loc of img "ImgToMove") - the mouseV into gDeltaV
end mouseDown
on mouseUp
movePPend
end mouseUp
on mouseMove
if (PXCROP_ISMOVING) then
if (the mouseLoc is within the rect of group "GpeViewer") then
set cursor to cross ////////
set the loc of img "ImgToMove" to (the mouseH + gDeltaH) & comma & (the mouseV + gDeltaV)
else movePPend
end if
end mouseMove
on movePPend
global PXCROP_ISMOVING
put false into PXCROP_ISMOVING
end movePPend

Hi Zax,
you need to UN-/LOCK the cursor!
Code: Select all
on mouseDown
put true into PXCROP_ISMOVING
LOCK CURSOR
set cursor to cross ////////
show img "ImgToMove"
...
on mouseUp
UNlock cursor
movePPend
end mouseUp
Best

Would it not be easier to simply:
Code: Select all
on mouseMove
if the mouse is down then set the loc of img "ImgToMove" to the mouseLoc
end mousemove

It occurs to me that you may need to filter that handler a little. Is there no other scenario where if you move the cursor while the mouse is down that you do NOT want that image to move? It seems unlikely that such a common action would work properly. I suggest that you consider something a little different:
Code: Select all
on mouseMove
if the optionKey is down then set the loc of img "ImgToMove" to the mouseLoc
end mousemove
Here it does not matter if the mouse is down or not, though you can also combine those two states.

Rereading yet again I see you want to:
Code: Select all
on mouseMove
if the mouse is down then
set the cursor to cross
lock cursor
set the loc of img "ImgToMove" to the mouseLoc
end if
end mousemove

Thanks Klaus and Craig
It works fine, and easier to read.

Zax.
Always good to hear of success.
What did you finally use to make it happen?

Craig,
I tried your elegant solution but:
1 - I need to do some stuff at the beginning of the movement
2 - the image to move is not at the mouse location (that's why I have deltaH and deltaV variables)
3 - I have some time consuming process to perform at the end of the movement
So I prefered my initial way, though it's a bit complicated.
Oh, and 4 - It's a weird project so I try different things but I don't know if the whole project is viable, or at least convenient for my use!

2 - the image to move is not at the mouse location
Do you want the image, at the point you move the mouse, to be at the mouseLoc?
2 possibilities:
Code: Select all
on mouseDown
set the loc of img "ImgToMove" to the mouseLoc
end mouseDown
on mouseMove
if the mouse is down then
set the cursor to cross
lock cursor
set the loc of img "ImgToMove" to the mouseLoc
end if
end mouseMove
that will centre the image on the
mouseLoc BEFORE you move the mouse.
Code: Select all
on mouseDown
set the topleft of img "ImgToMove" to the mouseLoc
end mouseDown
on mouseMove
if the mouse is down then
set the cursor to cross
lock cursor
set the topleft of img "ImgToMove" to the mouseLoc
end if
end mouseMove
that will make the mouse appear to grab the image by the
topleft and set the
topleft to the
mouseLoc BEFORE you move the mouse. If you move the mouse the image will continue to keep its
topleft at the
mouseLoc.

How did you spend your lunch hour?

The ONLY snag about this is that you have to click on a card to select it.

Haha, thanks Richmond
My movements scripts are OK, just look at the modified version of your stack:

That is alright IFF you ONLY have a single card,
ORR you can always click on a card rather than somewhere else.

Jax.
Anything that works is already just fine.
But you said:
the image to move is not at the mouse location (that's why I have deltaH and deltaV variables)
I just want to make sure I understand. My handler pops the image at the mouseLoc directly. What do you need beyond that?

Rather wise
Please DL the modified version of Richmond's stack I posted and you will understand what I needed - much better than with my poor words!
@Richmond: this time, I'm not trying to move playing cards, but... a hole. A real hole in the card that shows what is below (using a png image and the stack decorations).

Ah, OK, I read your first post:
I cannot use the Grab command because the image to be moved is not at the mouse location.
as having the image track the mouseLoc. Not a problem, the offset solution is straightforward.
When you say "move a hole" do you mean that this moving hole uncovers, to the extent of the hole itself, a portion of an image that sits below a blank white image or control? That the "hole" is a moving window "through" that white image?
If so I can think of a way to do that, but not directly, that is, that the hole somehow makes the round area it subtends transparent.
