find controls in a group

[fredigertsch]

How can I find all controls in a group? I have a group "gamboard" and within many groups "element". I like to find all groups "element".
How can I iterate through all objects?

Best, Fredi

The script below will list all the controls in a group and puts them in the variable 'myListOfControls'

Code: Select all

on mouseUp
   put 1 into count
   
   repeat for (the number of controls of grp 1) times
      put the name of control count of group 1 & cr into line count of myListOfControls
      add 1 to count
   end repeat
   
end mouseUp

be well

greetings

@Dixie,

Why do you need to concat the CR to the name of the element?

many thanks

Hi.

Dixie was ordering the results into separate lines for readability. Step through his script and you will see. As another way to do exactly the same, consider this:

Code: Select all

on mouseUp
repeat with y = 1 to the number of controls in group 1
  put the name of control y into line y of myListOfControls
end repeat
end mouseUp

I post this to show there are many ways to do things in LC, and as a new user, both will be very instructive. Please step through both scripts. Can you contruct others?

oh,I understood both scripts

but because I'm trying to create a list of controls to iterate them and make some changes on each, I was wondering if i would need the CR or not.

This is was I did:

Code: Select all

-- Get all Elementos of a Group
Function GetGroupElements cGroup
   put 1 into i
   put the number of controls of group cGroup into nrElems
   put empty into tArray
  
   repeat for (nrElems) times
      put the name of control i of group cGroup into line i of tArray
      add 1 to i
   end repeat
  
   return tArray
end GetGroupElements
  

should work, correct?

Manay thanks

Hi palanolho,

yes, should work, but "tArray" is NOT an array actually, but a CR delimited list!
I would name it: tList (or Harold)

[palanolho]

hmmm then what can i do to have an array?

[Klaus]

Well, depends on what you would like to see in the array
In this special case a CR delimited list will surely do!

A "simple" array with numerical keys:

Code: Select all

Function GetGroupElements cGroup
   put the number of controls of group cGroup into nrElems
   put empty into tArray
  
   repeat with i = 1 to nrElems
      put the name of control i of group cGroup into tArray[i]
   end repeat 
   return tArray
end GetGroupElements

Gives:
tArray[1][field "xxx"]
tArray[2][button "yyy"]
...


Best

Thank you very much

FWIW, v6.1 is in testing now and includes a new controlIDs property to return a list of controls in one line:
