Button Drop-menu need help with script

[Derek Henderson]

Using LiveCode Community edition version 8.0.1 on Windows 10 laptop

I have a button with a dropdown menu. I have based my code on the code provided by the Menu Builder. The code is accepted without errors. In run mode menu items selected are ignored. Below is a copy of the script:

on menuPick pWhich
switch --pWhich
case "New"
go back --Does not work
answer pWhich--Insert script for New menu item here
break
case "Edit"
answer pWhich--Insert script for Edit menu item here
answer pWhich
break
case "Delete"
answer pWhich--Insert script for Delete menu item here
break
case "Print"
answer pWhich--Insert script for Print menu item here
break
case "Graphs"
answer pWhich--Insert script for Graphs menu item here
break
case "Backup"
answer pWhich--Insert script for Backup menu item here
break
case "Restore"
answer pWhich--Insert script for Restore menu item here
break
case "Import"
answer pWhich--Insert script for Import menu item here
break
case "Export"
answer pWhich--Insert script for Export menu item here
break
case "Backup"
answer pWhich--Insert script for Backup menu item here
break
case "Restore"
answer pWhich--Insert script for Restore menu item here
break
case "Preferences"
answer pWhich--Insert script for Preferences menu item here
break
case "Help"
answer pWhich--Insert script for Help menu item here
break
case "Exdit Program"
quit
answer pWhich--Insert script for Exit menu item here
break
end switch
end menuPick
I would be most grateful for any assistance.

Hi Derek,

well, this should do the trick:

Code: Select all

on menuPick pWhich
  ## switch --pWhich
  switch pWhich
     case "New"
...

If you comment out the parameter -> pWhich, then the engine does not know
what exactly to "switch" and thus NO "case" will fit here!

And if you quit, the next line will of course never be executed:

Code: Select all

...
case "Exdit Program"
  quit
  answer pWhich--Insert script for Exit menu item here
break
...

Hi Derek,

very strange, just made a test with your script and it works as expsected!?

To be sure, your menuitems (text of button) are in fact:
New
Edit
Delete
Print
Import
Export
etc...
are they?

Add a default block which answers pWhich just to see if the switch block is working.
If so, then try changing the switch tests to

case pWhich = "New"
answer "New code goes here"
break

etc etc

[hpsh]

if it is the exit switch that is a problem, it is a spelling error there (in the word "Exdit")

Code: Select all

case "Exdit Program"
answer pWhich--Insert script for Exit menu item here
quit
break
end switch
end menuPick

should probably be

Code: Select all

case "Exit Program"
answer pWhich--Insert script for Exit menu item here
quit
break
end switch
end menuPick

Hi Klaus and hpsh
Tried the latest suggestions including the fix of error "exdit", however no luck.
Could it be that I originally copied all the code generated by the Menu Builder and thereafter manipulated the code to what I wanted.

I will clear all code and re-enter line by line.

Presumably it is not the copy from 8.01 to Community 7 causing this.
I will revert with the results.

Regards and many thanks for your help

      case "Help"
         answer pWhich--Insert script for Help menu item here
         break
      case "Exit Program"
         answer pWhich--Insert script for Exit menu item here
         quit
         break
   end switch
end menuPick

also, in propertys to the pulldownmeny i have the choises in the text part

Code: Select all

New
Edit
Delete
Print
Graphs
Backup
Restore
Import
Export
Backup
Restore
Preferences
Help
Exit Program

also including my code

i use livecode 8.0.1

just one thing, almost everyone here is better then me if someone disagree with me, i am most likely wrong.

[Klaus]

And of course everything works fine in your stack here on my Mac with LC 8.01!

[hpsh]

well, should probably said that i also use mac. osx 10.11.5. el capitan.

think only thing i changed was removing "d" from "exdit", and put in the choices in the pulldownmeny.

but pretty easy to to overlook something, remember some pretty amazing errors i did in borland turbo c in then i was young.

if i have space to it, i can try to install linux on my mac, and try the script there, but has to wait to i am home, begin to wonder if its a windows bug.

did try to install linux in a wm, and think i just has to leave that to anyone else, seems to be always some "usefull" function that kill any hope to test it for me.
