Better ComboBox gadget support

[Bitblazer]

The help page for the combobox gadget does not list disablegadget() as being supported. It seems to work to use disablegadget in windows to disable a combobox, but enabling doesnt seem to work. It would be nice to have a working dis/enable method for the combobox. The best documented replacement i found currently is to hide/unhide it and thats very poor style (confusing the user) as parts of an applications GUI disappear and appear again.

Tested with windows 7 x64 using PureBasic 5.62 x86

You're correct that the manual doesn't include DisableGadget() for the ComboBoxGadget() help entry, but disabling and enabling a ComboBoxGadget() works just fine here; and I have the same PC specs and PureBasic version as you. Can you post some code that shows the problem?

Then maybe its the combination with the PurevisionXP gadget library that i use for resizing. Not sure that posting a sample source makes much sense, its just a simple line "DisableGadget(Variable, 1)" and i use it a lot on buttons and the combobox i used to replace a button, is the first gadget that doesn't work flawlessly with that and with surprise i noticed that the documentation doesn't show the command in the help. So is it a documentation bug or a bug on my side or on yours even. Does it affect x86 or also x64 and what about the 5.7 beta?

Of course it makes sense, because we need to see how you're using the ComboBoxGadget() command. Is it just standard, or with supported flags like #PB_ComboBox_Editable (which changes its behavior), or even with unsupported flags like #WM_CLIPSIBLINGS? So until we know how you defined and are using it, we simply won't know why it's failing.

Could be. Anyway, try this code and let me know if it works:

Code: Select all

If OpenWindow(0, 200, 200, 300, 50, "ComboBox Disable Toggle", #PB_Window_SystemMenu)
  
  ComboBoxGadget(0, 10, 10, 280, 22)
  AddGadgetItem(0, -1, "This should toggle its disabled status")
  SetGadgetState(0, 0)
  
  AddWindowTimer(0, 123, 500)
  
  Repeat
    
    Event = WaitWindowEvent()
    
    If Event = #PB_Event_Timer And EventTimer() = 123
      state = 1 - state
      DisableGadget(0, state)
    EndIf    
    
  Until Event = #PB_Event_CloseWindow
  
EndIf

Your sample code actually works. I have a weird bug currently which affected the combobox. But if disablegadget on combobox is supported officially, somebody should report a documentation bug because the help does not mention it as being supported.
