Spin Gadget (und ein HinweiÃŸ fÃ¼r das Help-File

GPI · Post by **GPI** » Sun Jun 15, 2003 1:51 pm

Das Spin-Gadget enthÃ¤lt ja sowohl ein Text als auch einen (unsichbaren) Wert und das macht die Handharbung etwas schwieriger. Das Beispiel in der deutsch Anleitung ist nicht so gut:
A) Eingaben in Text-Bereich werden ignoriert
B) Mich stÃ¶rt das zusÃ¤tzliche eventwindow() gewaltig...

Hier meine LÃ¶sung

Code: Select all

If OpenWindow(0,0,0,140,70,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"SpinGadget") And CreateGadgetList(WindowID(0)) 
    SpinGadget     (0,20,20,100,25,0,1000) 
    SetGadgetState (0,5) : SetGadgetText(0,"5")   ; Anfangswert festlegen 
    Repeat 
      ev.l = WaitWindowEvent() 
      If ev=#pb_event_gadget
        If EventGadgetID() = 0 
          If GetGadgetState(0)<>Val(GetGadgetText(0)) ; hat sich was geÃ¤ndert?
            If EventType()=#pb_eventtype_change ; = Eingabe in Textfeld
              SetGadgetState(0,Val(GetGadgetText(0)))
            Else
              SetGadgetText(0,Str(GetGadgetState(0)))
            EndIf
          EndIf
        EndIf
      EndIf 
    Until ev.l = #PB_Event_CloseWindow 
  EndIf

p.s.: Man muÃŸ nicht unbedingt die Ziffern in Text-Feld schreiben, man kann da auch zwischen verschieden WÃ¶rtern umschalten...

Hey GPI

Wrong forum?

Ah, Yes, complete wrong forum.

OK: Here a little translation of the text above:
In the german manual is a example of a spin-gadget, but there are two problems:
a) the example don't react, when i write text in the textbox of the spin
b) it used a windowevent() to throw a message away.

My Example above, shoes how the spin-gadget can handle correct, so that the user can type a value in the text box and can use the arrow buttons.

Hey GPI, thanks for your suggestions. They are noticed, even when they are in german.....

GPI,

Nice tip! It might be good to check if something other than a number is typed into the SpinGadget. That way, you can keep the value unchanged, instead of setting it to zero (Val() of a non-numeric = 0).

Thanks,
Eric
