I'm looking for a way to get the background color of a listicongadget when it is disabled.
I didn't find a solution, i try with some API but without succes.
It is possible to have two ways, one with themes, the oder one without.
Tks

Code: Select all
color = SendMessage_(<listicon>,#LVM_GETBKCOLOR,0,0)
Should work whether disabled or not.

Hi netmaestro,
that's the first code i try but it returns the normal background color (under vista for my computer, white and the disabled color is a light gray).

Not so easy, eh? When the going gets tough, the tough... cheat!
Code: Select all
OpenWindow(0,0,0,320,240,"",#PB_Window_SystemMenu|#PB_Window_ScreenCentered)
ListIconGadget(0,0,0,200,200,"Column 0",200)
DisableGadget(0,1)
color = SendMessage_(gadgetid(0),#LVM_GETBKCOLOR,0,0):Debug color ; wrong
; Ok, another try:
hdc = GetDC_(gadgetid(0))
color = GetPixel_(hdc, 2,30)
ReleaseDC_(gadgetid(0), hdc)
Debug color ; looks right
quit=0
Repeat
Select WaitWindowEvent()
Case #PB_Event_CloseWindow
quit=1
EndSelect
Until quit

Is it not just the #COLOR_BTNFACE system color which you can retrieve with GetSysColor_() ?

Yes, it is.

Ok you guys, if you're going to start making sense I don't know what I'm going to do!

Don't worry, it was just a rare moment of lucidity fuelled by a lack of alcohol! It won't happen again!

We *almost* believe Srod, but as he is known to delve into the deep and dark recesses of the human mind (and appearently meets the likes of us down there
) we do put some question marks around his (or our
) soberness...
Well, at least it did not involve hamsters.

no. there was something lately in the german forums...
if I remember correctly, it strongly depends on the skinning.
if it's the same as ButtonFace, it's just a coincidence.

I didn't get good result with Listicon inside a nxSplitter (from srod lib), i just get a color value of $FFFFFFFF. So i've created an hidden listicon outside nxSplitter and that's Ok.

Well yes if you skin a control then you cannot rely on any color value. By default Windows will use the #COLOR_3DFACE (#COLOR_BTNFACE) for these things.
@Denis : works fine here with a disabled ListIcon inside an nxSplitter. If you create the ListIcon with zero width and height (ready for the splitter) then only use netty's code after placing the control inside the splitter; otherwise you will get a color value of -1 ($ffffffff). As I say, works fine here.

Ok srod, i will try this.

Denis, if you haven't applied any skinning then GetSysColor_() should give you the correct result and saves you having to retrieve a pixel etc.
