Hi all,

i try to create a new start menu dynamically with the om.domnode method.

this is my code:



OPEN WINDOW win01 WITH 20 ROWS , 50 COLUMNS

      LET txt_menu = "Prog 1.0  -  ",   
 
      LET aui = ui.interface.getRootNode()
   
      LET sm  = aui.createChild("StartMenu") -

      CALL ui.Interface.loadActionDefaults(name_4ad)
      CALL ui.Interface.loadStyles(name_4st)
      CALL ui.Interface.setImage("image")
      CALL ui.Interface.setType("container")
      CALL ui.Interface.SetName("menu"||id)
      CALL ui.Interface.setText(txt_menu)


       LET smg = createStartMenuGroup(sm,"Ordering")
       LET smc = createStartMenuCommand(smg,"Orders","fglrun orders.42r",NULL)
       LET smc = createStartMenuCommand(smg,"Customers","fglrun custs.42r",NULL)
       LET smc = createStartMenuCommand(smg,"Items","fglrun items.42r",NULL)
       LET smc = createStartMenuCommand(smg,"Reports","fglrun reports.42r",NULL)
       LET smg = createStartMenuGroup(sm,"Configuration")
       LET smc = createStartMenuCommand(smg,"Database","fglrun dbseconf.42r",NULL)
       LET smc = createStartMenuCommand(smg,"Users","fglrun userconf.42r",NULL)
       LET smc = createStartMenuCommand(smg,"Printers","fglrun prntconf.42r",NULL)

       MENU "Example"
         COMMAND "Quit"
           EXIT PROGRAM
       END MENU

     close window win01

END MAIN

FUNCTION createStartMenuGroup(p,t)
  DEFINE p om.DomNode
  DEFINE t STRING
  DEFINE s om.DomNode
  LET s = p.createChild("StartMenuGroup")
  CALL s.setAttribute("text",t)
  RETURN s
END FUNCTION

FUNCTION createStartMenuCommand(p,t,c,i)
  DEFINE p om.DomNode
  DEFINE t,c,i STRING
  DEFINE s om.DomNode
  LET s = p.createChild("StartMenuCommand")
  CALL s.setAttribute("text",t)
  CALL s.setAttribute("exec",c)
  CALL s.setAttribute("image",i)
  RETURN s
END FUNCTION

the menu work fine but is generated in the window "screen" and not in my "win01".
is possible generate them in a window different from the screen?
in the window "screen" the command       
     CALL ui.Interface.SetName("menu"||id)
      CALL ui.Interface.setText(txt_menu)
doesnìt work! why?

thanks

Hello Luca,

StartMenu was implemented before Genero introduced TreeViews.

You may want to consider to implement your program starter with TreeView, to have full control...?

You can have a look at the FGLDIR/demo/demo.4gl program.

Hi Luca, the reason that you don't see the start menu in your own window is that a "normal" window does not have a "startMenuPosition" style attribute set (see $FGLDIR/lib/default.4st), only Window.main has set <StyleAttribute name="startMenuPosition" value="menu" />

The implicit opened "screen" window has the "main" style set, thats why you see it only on "screen".
Now just give your window the main style

OPEN WINDOW win01 WITH 20 ROWS , 50 COLUMNS  ATTRIBUTE(STYLE="main")

and you see it also in your window.
Nevertheless you can do everything you do with win01 also with "screen" so there is no reason to open an extra window.
 <<CALL ui.Interface.SetName("menu"||id)
 <<CALL ui.Interface.setText(txt_menu)
These API calls are foreseen for MDI containers, you can use either
CALL fgl_setTitle(txt_menu) --easy
or
DEFINE w ui.Window
LET w=ui.Window.getCurrent()
CALL w.setText(txt_menu) --you need a window variable

HTH and Regards, Leo

Thanks Leo S.

with your solution now it work.

for Sebastien

i saw this solution but i want to give to the final user two solution, the "StartMenu" and the "TreeView" and in my opinion the "TreeView" is not much user friendly for a Menu

thanks
