Hi David
Yes LC can
Something like that:

Code: Select all

on setLayerControl pControl,pGroup
   put getMaxLayerInGrp(pGroup) into tTopLayerOfGrp
   set the relayerGroupedControls to true
   relayer control pControl  after control tTopLayerOfGrp
   set the relayerGroupedControls to false
end setLayerControl

function getMaxLayerInGrp pGroup
   put the num of controls of group pGroup into tNbControls
   put the short name of control tNbControls of group pGroup into rMaxLayerInGrp
   return rMaxLayerInGrp
end getMaxLayerInGrp

Best regards

So . . . I would be inclined to ungroup the group, reorder the objects and then regroup them again.

2 lines of code!

Code: Select all

on mouseUp
   ungroup group "bunch"
   group img "three" and img "two" and img "one"
end mouseUp

Thanks for the suggestions.

The group I am working with is in a mobile scroller with more than 40 items in the group,
witch are being inserted by the user. I need to keep my pointer on top of the newly inserted
objects. As a work around, i am currently deleting and copying the pointer after each new object is
inserted to keep the pointer on top. It works OK, but I thought the might be a better way.

Thanks both of you for your help,

David

Hi David,
Did you try to adapt scripts i posted to your context ?

Richmond.

That was adorable.

David.

But is it necessary to do anything more than:

Code: Select all

set the screenMouseLoc to the loc of last control

(You have to do the usual calcs to adjust loc of the card window to screen "0,0".)

This begs whatever method you use adding the newly created control to the group. The only reason I am posting is because the original question was how to "locate" the newly added control, not how to add the control to the group. For example, you could copy the new control to the group, and then delete the original.

Fun stuff...

Craig,

I don't see how "set the screenMouseLoc to the loc of last control" is going to change a layer property.

Jean-Marc,

I don't understand what "getMaxLayerInGrp(pGroup)" is.

Thanks,

David

It doesn't. I guess I misunderstand what you are trying to do.

You said you wanted to set the pointer to the loc of the most recent control, which is created by the user. My only point was one way to do that. Relayering is not required.

It is is another matter entirely to include that control in the group. If other actions create, say, other controls in other groups, then certainly managing the members of each group is important.

You could have a list field where each line contains the name of an object within a group:
new ones being added at the start of the list.

Then you could have a script that set the object in line 1 of your list to the top layer inside your group.

Thanks everyone for all the good suggestions, but they seem like too much work.
I think I will just keep deleting the pointer group and then coping it back after
new control is copied to keep it on top layer.

Ahem...

A closer look at RELAYER in the dictionary will show you that you can

Code: Select all

relayer <objectref> to front of group <groupref>

(or to back, to put it to the lowest layer of the group)

You can deal with nesting of groups by including "the owner" as a self-reference

Code: Select all

relay me to front of the owner of me

will set the layer to the topmost layer of the group it is in, without bleeding into any other nested groups.

SparkOut,

WOW!

The code "relayer <objectref> to front of group <groupref>" works Great!


Thanks SO MUCH,

David
