Hello,
I define the action defaults in the per-File

action defaults
   action key_f7   (text= "F7 allg. Texte", accelerator=F7)
   action key_f8   (text= "F8 Lieferanschriften", accelerator=F8)
end

Now I want to change the text for the action key_f7 in my 4gl program.

I tried "setElementText", but this didn't work.

Has anyone an idea

Stefan

Hi Stefan, could you please explain in which situation the text should change?
Is it that you want to re use F7 in another context (that means the semantic of the action changes?)
So pressing F7 no longer shows general purpose text but does something else?

Kind Regards, Leo

Stefan,
If you don't insist on ON ACTION you can achieve what you want with some BDL compatible statements using ON KEY()
(I guess the primary focus is on having a well defined Function key order)
Paste the code below and tell me if this is what you were looking for
Kind Regards, Leo
--------------keylabel.4gl--------------
MAIN
  DEFINE a,b STRING
  OPEN FORM f FROM "keylabel"
  DISPLAY FORM f
  INPUT BY NAME a,b
    ON KEY(F7)
      IF INFIELD(a) THEN
        DISPLAY "F7 in a"
      ELSE
        DISPLAY "F7"
      END IF
    ON KEY(F8)
      IF INFIELD(b) THEN
        DISPLAY "F8 in b"
      ELSE
        DISPLAY "F8"
      END IF
  END INPUT
END MAIN

Thanks,

the reason why I wnat to change the text is simple.
I have a form with 3 arrays.
From Array 1 I switch with "F7" to array 2 to see details und from array 2 I switch to array 3 to See some Text. But the User should only press F7 twice to switch between the arrays.

If  I have to work with "on key" instead of "on action" , then I can use fgl_setkeylabel ("F7", "F7 - Details").
We changed our program from "on action" back to "on key" and now it worked.

But it would be fine to have the posibility to change the action text


Stefan

May be you need to post some more code.
From your description I cannot deduce if you are using singular dialogs or a multiple dialog.
Since Multiple Dialogs are there you would be able to switch between arrays via the "Tab" key if you are willing to pack your array handling code into 1 DIALOG instruction (assuming the code for all 3 arrays is in 1 module).
In singular dialogs if you invoke a 2nd dialog in a chain you could load different action defaults for 1 and the same action.
I was assuming you need that in one and the same dialog.

Hi Stefan,

I have forms with several actions having the same accelerator. As long as only one of these actions is active you get the text you expect. eg:

ACTION insert_meeting ( TEXT="Add Meeting", image="plus", ACCELERATOR=F3, COMMENT="Add a new meeting" )
ACTION new_raceday ( TEXT="New Day", image="plus", ACCELERATOR=F3, COMMENT="Add a new raceday")


  but both actions are not referenced in the same input/display statement so only the correct text shows.
Does this do what you want?

The functions below should do what you are after.  They are from my auitree example on sourcefourjs http://code.google.com/p/sourcefourjs/wiki/auitree

...
INPUT ARRAY
   BEFORE INPUT
      CALL action_text_set("key_f7", "Details")
...
...
INPUT ARRAY
   BEFORE INPUT
      CALL action_text_set("key_f7", "Text")
...
 
 
 
#+ action_text_set Change the text attribute of a given action
FUNCTION action_text_set(action, text)
DEFINE action, text STRING
DEFINE n om.DomNode
 
   LET n = action_node_get(action)
   IF n IS NOT NULL THEN
      CALL n.setAttribute("text", text)
   END IF
END FUNCTION
 
 
FUNCTION action_node_get(name)
DEFINE name STRING
DEFINE w ui.Window
DEFINE n,f om.DomNode
DEFINE nl om.nodeList
 
   LET w = ui.Window.getCurrent()
   LET n = w.getNode()
   LET nl = n.selectByPath(SFMT("//Action[@name=\"%1\"]",name))
   IF nl.getLength() != 1 THEN
      LET nl = n.selectByPath(SFMT("//MenuAction[@name=\"%1\"]",name))
   END IF
   IF nl.getLength() = 1 THEN
      LET f=  nl.item(1)
   END IF
   RETURN f
END FUNCTION

many thanks Reuben,

this is what I need.


Kind regards

Stefan
