ActivateGadget()

Syntax

ActivateGadget(#Gadget)

Activates (sets the focus on) the gadget specified by the given #Gadget identifier. This is mainly used with ComboBoxGadget() and StringGadget(). Activating a gadget allows it to become the current object to receive messages and handle keystrokes.

Example:

  If OpenWindow(0,0,0,270,140,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"ActivateGadget") And CreateGadgetList(WindowID(0))
    StringGadget  (0,10, 10,250,20,"bla bla...")
    ComboBoxGadget(1,10, 40,250,100)
    For a=1 To 5 : AddGadgetItem(1,-1,"ComboBox item "+Str(a)) : Next
    SetGadgetState(1,2)                ; set (beginning with 0) the third item as active one
    ButtonGadget  (2,10, 90,250,20,"Activate StringGadget")
    ButtonGadget  (3,10,115,250,20,"Activate ComboBox")
    Repeat
      Event = WaitWindowEvent()
      If Event = #PB_Event_Gadget
        Select EventGadgetID()
          Case 2 : ActivateGadget(0)   ; Activate StringGadget
          Case 3 : ActivateGadget(1)   ; Activate ComboBoxGadget
        EndSelect
      EndIf
    Until Event = #PB_Event_CloseWindow
  EndIf
