Hello!

since PB4, you have to place the Window parameter in the WindowID() function. In PB3.94, I was able to determine the current window using WindowID() without parameters.

However, I am making a custom gadget library and I thought it would be "handier" if the user doesn't need to supply the hWnd.

I am using Win32 API calls, like CreateWindowEx_() and so on.
Let's assume this is my current code:

Code: Select all

Procedure MyCustomGadget(Window, x, y, Width, Height)
 CreateCustomGadget(WindowID(Window), x, y, Width, Height)
EndProcedure

It would be better if it would look like this, wouldn't it?

Code: Select all

Procedure MyCustomGadget(x, y, Width, Height)
 Window=GetCurrentWindow()
 CreateCustomGadget(Window, x, y, Width, Height)
EndProcedure

The GetCurrentWindow() function should return the hWnd of the calling window. (For example, window #0 calls MyCustomGadget(), the procedure calls GetCurrentWindow() and the result is equal to WindowID(0))

I am asking how to achieve this, as I am sure there's a workaround, but I did not stumble in it yet.

Thanks! Any help is appreciated!

GetForegroundWindow() ?

doesn't help much, as the window which calls the procedure can be hidden or not in the foreground.

As PB is not documented at the moment you can't be sure if this is right,
but it seems to work:

Code: Select all

OpenWindow(0, 0, 0, 200, 200,"")
CreateGadgetList(WindowID(0))
OpenWindow(1, 0, 0, 200, 200,"")
CreateGadgetList(WindowID(1))

a.l
!EXTRN _PB_Gadget_Objects
!MOV Eax, [_PB_Gadget_Objects+16]
!MOV Eax, [Eax]
!MOV [v_a], Eax

Debug a
Debug WindowID(1)

I get "Invalid Memory Access" at line 6. Using WinME.

Right, in Debug mode it works here

So you have to wait for an "official" solution, but i think, there wont be
one :roll:

well, it's not a problem but I'd like to have the WindowID() function again with the optional parameter

Sorry, I should have read your post more carefully.

Just saw "get current window" twice or something,
that's what GetForegroundWindow() does
