Why is the button not activated by pressing return ?

Hi,

I just discoverd, that a ButtonGadget() is not activated by pressing return if the button
is the active gadget.

Is this normal ?

What can I do to make it behave as I want ?
(PB 4.60 Win 32)

Code: Select all

OpenWindow(0, 0, 0, 120, 40, "", #PB_Window_ScreenCentered | #PB_Window_SystemMenu)

ButtonGadget(0, 10, 10, 100, 20, "Press return")
SetActiveGadget(0)

Repeat
  Event = WaitWindowEvent()
  If Event = #PB_Event_Gadget
    If EventGadget() = 0
      Debug "Pressed"
    EndIf
  EndIf
Until Event = #PB_Event_CloseWindow

Hi,

as far as I know this is normal. At lest on Windows, we are supposed to press [Space] instead of [Return]. :-)

I use AddKeyboardShortcut() to make it behave that way.

Hm,

ok, AddKeyboardShortcut() is a solution.

But the MessageRequester() buttons from Windows (for example) works with return.
So I thought that also the buttons of PB are working with return and not with space :(

As far as I can see, buttongadgets don't generate events upon given focus, not like a string gadget or list/listicon, they just become the active gdadget.

I found this code in the forum to generate events to send to gadgets though, from a post by t57042

(PB 4.60 Win 32)

Import "gadget.lib"
PB_Gadget_SendGadgetCommand(hWnd, EventType)
EndImport

PB_Gadget_SendGadgetCommand(GadgetID(1), #PB_EventType_LeftClick)

Hi everyone
@infratec I just used the document example
There is no mention for #PB_EventType_ReturnKey as you can see
Next is for Windows

Code: Select all



OpenWindow(0, 0, 0, 120, 40, "", #PB_Window_ScreenCentered | #PB_Window_SystemMenu)
ButtonGadget(0, 10, 10, 100, 20, "Press return")
SetActiveGadget(0)

Repeat
       Event = WaitWindowEvent()       
       Select Event       
        Case #PB_Event_Gadget
           Select EventGadget()
             Case 0
               Select EventType()               
                 Case #PB_EventType_LeftClick        : Debug "Click with left mouse button"
                 Case #PB_EventType_RightClick       : Debug "Click with right mouse button"
                 Case #PB_EventType_LeftDoubleClick  : Debug "Double-click with left mouse button"
                 Case #PB_EventType_RightDoubleClick : Debug "Double-click with right mouse button"
               EndSelect
           EndSelect
           
        Case #WM_CHAR
          Select EventwParam()
            Case 13
                AG = GetActiveGadget()
                PostMessage_(GadgetID(AG), #WM_LBUTTONDOWN, 0, 0)
                PostMessage_(GadgetID(AG), #WM_LBUTTONUP, 0, 0)

          EndSelect
      
       EndSelect
     Until Event = #PB_Event_CloseWindow

Yes,
but why it works with the space key ?

Btw. thanks for your code.
But to be crosscompatible I will use AddKeyboardShortcut() and put all my button event stuff in
own procedures.

This is an example how I use to solve the problem:

Code: Select all

EnableExplicit

;-- Windows
Enumeration
   #MyWin
EndEnumeration

;-- Gadgets
Enumeration
   #Btn_Ok
EndEnumeration

;-- Keys for shortcuts
Enumeration 1
   #KeyReturn
EndEnumeration


Define Event, Gadget

OpenWindow(#MyWin, 0, 0, 120, 40, "", #PB_Window_ScreenCentered | #PB_Window_SystemMenu)
ButtonGadget(#Btn_Ok, 10, 10, 100, 20, "OK")
SetActiveGadget(#Btn_Ok)
AddKeyboardShortcut(#MyWin, #PB_Shortcut_Return, #KeyReturn)

Repeat
   Event = WaitWindowEvent()
   Gadget = EventGadget()
   
   If Event = #PB_Event_Menu
      If EventMenu() = #KeyReturn
         Event = #PB_Event_Gadget
         If GetActiveGadget() = #Btn_Ok
            Gadget = #Btn_Ok
         EndIf               
      EndIf
   EndIf
   
   If Event = #PB_Event_Gadget
      If Gadget = #Btn_Ok
         Debug "'OK' pressed"
      EndIf   
   EndIf
Until Event = #PB_Event_CloseWindow

:mrgreen:
I never noticed that or maybe I forget about that after long time
I think the team have some problems with the Return Key and different types of
objects

Variation of the above. (but no libs required and still using Windows API stuff)

You can actually *see* the button move.

Code: Select all

OpenWindow(0, 0, 0, 120, 40, "", #PB_Window_ScreenCentered | #PB_Window_SystemMenu)
ButtonGadget(0, 10, 10, 100, 20, "Press return")
SetActiveGadget(0)

Repeat
  Event = WaitWindowEvent()
  Select Event       
    Case #PB_Event_Gadget
      Select EventGadget()
        Case 0
          Select EventType()               
            Case #PB_EventType_LeftClick        : Debug "Click with left mouse button"
            Case #PB_EventType_RightClick       : Debug "Click with right mouse button"
            Case #PB_EventType_LeftDoubleClick  : Debug "Double-click with left mouse button"
            Case #PB_EventType_RightDoubleClick : Debug "Double-click with right mouse button"
          EndSelect
      EndSelect
      
    Case #WM_CHAR
      Select EventwParam()
        Case 13
          keybd_event_(#VK_SPACE,0,0,0)
          WaitWindowEvent()
          WaitWindowEvent()
          WaitWindowEvent()
          keybd_event_(#VK_SPACE,0,0,0)
          keybd_event_(#VK_SPACE,0,#KEYEVENTF_KEYUP,0)
          
      EndSelect
      
  EndSelect
Until Event = #PB_Event_CloseWindow

@Bernd,
This way you can have the exact same effect as the MessageRequester.
As it uses API, it is Windows only.

Code: Select all

Procedure zOclick(Gadget.i)
      GetCursorPos_(cp.POINT)
      GetWindowRect_(GadgetID(Gadget),r.RECT)
      SetCursorPos_((r\left),(r\top))
      mouse_event_(#MOUSEEVENTF_LEFTDOWN,0,0,0,0)
      mouse_event_(#MOUSEEVENTF_LEFTUP,0,0,0,0)
      SetCursorPos_(cp\x,cp\y)
EndProcedure

Win=OpenWindow(#PB_Any, 0, 0, 320, 240, "", #PB_Window_ScreenCentered | #PB_Window_SystemMenu)
    BtnOk=ButtonGadget(#PB_Any, 10, 180, 88, 26, "OK", #PB_Button_Default)
    AddKeyboardShortcut(Win, #PB_Shortcut_Return, 13)
    SetActiveGadget(BtnOk)
    MessageRequester("Real MessageRequester","This is the real MessageRequester")
    Repeat
        Event = WaitWindowEvent()
        Select Event
            Case #PB_Event_Menu
                Select EventMenu()
                    Case 13
                        zOclick(BtnOk)
                EndSelect  
            Case #PB_Event_Gadget
                Select EventGadget()
                    Case BtnOk
                        Debug "Pressed"
                EndSelect
        EndSelect
    Until Event = #PB_Event_CloseWindow
- Clicking on OK works.
- Pressing Space works.
- Pressing Return works.

The procedure zOclick simulates a mouse click.
Additionally, the flag #PB_Button_Default on the button definition gives the appearance of a default button.
