Why? If I do the same with ComboGadget(), no event is triggered. On Windows it works as expected (no events are triggered in general, but on Windows I wonder why SetGadgetState initially deselects the entry - with a separate event! - before a new is selected). No idea if this is a bug or or another inconsistency between Windows and macOS that PureBasic users have to live with (In that case, the question would be why the PB command SetGadgetState does not automatically remove this inconsistency.)... Thank you for any clarification

Output Windows:

ListIcon clicked:
---> "ListIconGadget changed to -1" (Why a deselection is forced before a new selection?)
---> "ListIconGadget changed to 3"
Combobox clicked:
---> "ComboBoxGadget changed to 3"
Button Clicked:
---> "Button pressed"

Output macOS:

ListIcon clicked:
---> "ListIconGadget changed to 3"
Combobox clicked:
---> "ComboBoxGadget changed to 3"
Button Clicked:
---> "Button pressed"
---> "ListIconGadget changed to 3" (Why an #PB_EventType_Change is triggered with SetGadgetState?)

Code: Select all

#li = 0
#cb = 1
#bt = 2

Procedure li()
  Debug "ListIconGadget changed to " + Str(GetGadgetState(#li))
EndProcedure

Procedure cb()
  Debug "ComboBoxGadget changed to " + Str(GetGadgetState(#cb))
EndProcedure

Procedure bt()
  Debug "Button pressed"
  Repeat
    rnd = Random(9)
  Until rnd <> GetGadgetState(#li) ; not the same slot
  SetGadgetState(#li, rnd)
  Repeat
    rnd = Random(9)
  Until rnd <> GetGadgetState(#cb) ; not the same slot
  SetGadgetState(#cb, rnd)
EndProcedure

OpenWindow(0, 0, 0, 600, 400, "ListIcon Example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ListIconGadget(#li, 5, 5, 400, 300, "Name", 100, #PB_ListIcon_FullRowSelect | #PB_ListIcon_AlwaysShowSelection)
AddGadgetColumn(#li, 1, "Address", 250)
ComboBoxGadget(#cb, 5, 320, 300, 26)
ButtonGadget(#bt, 450, 20, 100, 40, "RND")

For i = 0 To 9
AddGadgetItem(#li, i, Str(i) + " Harry Rannit"+Chr(10)+"12 Parliament Way, Battle Street, By the Bay")
AddGadgetItem(#cb, i, Str(i) + " Harry Rannit, 12 Parliament Way, Battle Street, By the Bay")
Next i
SetGadgetState(#li, 0)
SetGadgetState(#cb, 0)

BindGadgetEvent(#li, @li(), #PB_EventType_Change)
BindGadgetEvent(#cb, @cb(), #PB_EventType_Change)
BindGadgetEvent(#bt, @bt())

Repeat
  Event = WaitWindowEvent()
Until Event = #PB_Event_CloseWindow
