Detect Change on Date and Option Gadgets

Firstly, apologies if this has already been answered, I
did do a search.
I'm trying to get the date and option gadgets to generate a #PB_EventType_Change message.
I've tried the trick (API call) that enables changes for the Editor gadget but it doesn't work for these.
Would be grateful for a hint!
Many thanks

Hi,
for the DateGadget() I found this:
Code: Select all
If OpenWindow(0, 0, 0, 200, 250, "DateGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
DateGadget(0, 10, 10, 180, 25, "Datum: %mm/%dd/%yyyy Time: %hh:%ii")
Exit = #False
Repeat
Event = WaitWindowEvent()
Select Event
Case #PB_Event_Gadget
Select EventGadget
Case 0 : Debug "Changed"
EndSelect
Case #PB_Event_CloseWindow
Exit = #True
EndSelect
Until Exit
EndIf

For the OptionGadget() I found
Code: Select all
If OpenWindow(0, 0, 0, 140, 110, "OptionGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
OptionGadget(0, 30, 20, 60, 20, "Option 1")
OptionGadget(1, 30, 45, 60, 20, "Option 2")
OptionGadget(2, 30, 70, 60, 20, "Option 3")
SetGadgetState(1, 1) ; wir setzen die zweite Option als aktiv
Exit = #False
Repeat
Event = WaitWindowEvent()
Select Event
Case #PB_Event_Gadget
Select EventGadget()
Case 0 : Debug 1
Case 1 : Debug 2
Case 2 : Debug 3
EndSelect
Case #PB_Event_CloseWindow
Exit = #True
EndSelect
Until Exit
EndIf

Well, I only hope that you didn't find it in the English-speaking forum or I can't work the search as well as standard PB event handling
Thank you so much Bernd.
What's strange is that I thought my original code did just that! When it didn't work for Editor, date and option gadgets, I went looking. I found the solution to the editor gadget and assumed there was a 'special' solution to the other two.
Now I just need to work out why my original code doesn't work.
Thanks again!

Ahhhh, I see what's going on. Your examples aren't qualifying the EventType as changed...
You are getting any event related to that gadget.
Which seems to work! I wonder if it will backfire on me later

There is no "#PB_EventType_Change" documented!
The only eventtype was "#PB_EventType_LeftClick"
Code: Select all
If OpenWindow(0, 0, 0, 140, 110, "OptionGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
OptionGadget(0, 30, 20, 60, 20, "Option 1")
OptionGadget(1, 30, 45, 60, 20, "Option 2")
OptionGadget(2, 30, 70, 60, 20, "Option 3")
SetGadgetState(1, 1) ; wir setzen die zweite Option als aktiv
Exit = #False
Repeat
Event = WaitWindowEvent()
Select Event
Case #PB_Event_Gadget
Select EventGadget()
Case 0
If EventType() = #PB_EventType_LeftClick : Debug 1 : EndIf
Case 1 : Debug 2
Case 2 : Debug 3
EndSelect
Case #PB_Event_CloseWindow
Exit = #True
EndSelect
Until Exit
EndIf
but using of eventtype is useless in this case

And since there is only one event,
you don't need to check the EventType() (at the moment
)

Thanks guys.
Yes, I know there is no Change event documented. There isn't one documented for the Editor gadget either but it can be enabled via the WinApi, hence my assumption that something similar might be possible here.
But the lonely left click event will do nicely
Cheers.

Are we talking about 4.60?
#PB_EventType_Change is documented here:
http://www.purebasic.com/documentation/ ... adget.html
I use it and it works fine for me.
See this thread for some background:

We talking about 4.60, Date- and Optiongadget, not ComboboxGadget
