How to set the location of an Answer/Ask dialog

[keram]

Hi,

Normally the answer and ask dialogs are horizontally and vertically centered. I'd like to center it horizontally but place it about 2/3 from the top.
I've searched the forum for this and did not find any simple clear answers.
One of them is from FourthWorld http://forums.livecode.com/viewtopic.ph ... wer+dialog

function AlertLoc
return item 1 of the screenLoc, (item 4 of the screenRect div 5 )*2
end AlertLoc

but I don't know how to apply this. Anybody could explain or maybe give another solution?

Thanks!

Hi Keram,
There is a little stack that does the job

Thanks Jean-Marc,

I tested that stack and it works very well in IDE and in the Windows standalone but in Android standalone it does not.
Since I want that answer dialog to show up when the Android back key is tapped on while the first card is visible, I adjusted the code in this way:

in the stack:

Code: Select all

on backKey
   if the number of this card is 1 then
      pass backKey
   else
      go to the previous card
   end if
end backKey

in the card:

Code: Select all

on mouseUp
   lock screen for visual effect
   unlock screen with visual effect dissolve to white very slow
   go cd "firstQ"
end mouseUp

on backKey
   put loc of stack "allin1P" into tStackLoc
   put (item 2 of tStackLoc) * 1.25 into item 2 of tStackLoc
   setAnswerLoc tStackLoc
   answer question "Do you want to exit the app?" with "Yes" or "No"
   if it is "Yes" then quit
   setAnswerLoc "abc" --This should do nothing and should not throw an error.
   setAnswerLoc --This should restore the default loc
end backKey

on setAnswerLoc tLoc
   local answerScript, tScript, tCount, tParams, tLineNo, tNewScriptLine
   put the answerScript of this card into tScript
   if tScript is "" then
      put  the script of card 1 of stack "answer dialog" into tScript
      set the answerScript of this card to tScript
      -- Best to keep a clean copy of that script somewhere accessible
   end if
   put the paramcount into tCount
   put the params into tParams
   switch tCount
      case 0
         set the script of card 1 of stack "answer dialog" to the answerScript of this card
         exit setAnswerLoc
         break
      default
         delete word 1 of tParams
         replace quote  with "" in  tParams
         put tParams into tLoc
         if word 1 of item 1 of tLoc is not a number or word 1 of item 2 of tLoc is not a number then
            --Abandon ship. Reset the default script for the answer stack.
            set the script of card 1 of stack "answer dialog" to the answerScript of this card
            exit setAnswerLoc
         end if
   end switch
 
   put lineoffset("end preOpenStack", tScript)  into tLineNo
   --Write the line of code to immediately preceed "End preOpenStack" 
   put "Set the loc of this stack to "& tLoc  into tNewScriptLine
   --Alter the script
   --Change the last line of PreOpenStack to the following 2 lines.
   put tNewScriptLine & cr & "end preOpenStack" into line tLineNo of tScript
   --Set the new script.
   set the script of card 1 of stack "answer dialog"  to tScript
end setAnswerLoc

Is it something that I have to specifically add or change for Android?

Mobile has very specific needs that are quite different from the desktop. While it may be possible to come up with a solution for positioning LC's ask/answer dialogs in specific locations for specific moments for one specific app, it would seem much easier to just make a group that overlays your UI to do exactly what you want however you want it.

Hi Keram,
As Richard said, group is a easy way in your case and you can customize it for each use
I think you can have only one group for all dialog. Just place this group onto the current cd when you need it.
More. This dialog will be more accessible than the classic dialog
