It should also capture a windowscreen and for Vista / Win7 compatibility, it might also need enable DwmEnableComposition
Code: Select all
Procedure DWMEnableDisable(OnOff.i)
Protected *pAfunc,Lib
Lib = LoadLibrary_("dwmapi.dll")
If Lib
*pAfunc = GetProcAddress_(Lib, "DwmEnableComposition")
If *pAfunc
CallFunctionFast(*pAfunc, OnOff)
EndIf
FreeLibrary_(Lib)
EndIf
EndProcedure

Back for another question, nco2k.
On the first page of this thread, you showed how to do a thumbnail of a window. Are you able to explain how to show just a portion of the source window as the thumbnail in the target window? Everything I've tried always shows the entire source window as a thumbnail.
Aiming to do like this app:
https://github.com/LionelJouin/PiP-Tool
So I know it's possible. The relevant part of my source is this:
Code: Select all
dwm_thumbnail_properties\rcSource\left=x
dwm_thumbnail_properties\rcSource\top=y
dwm_thumbnail_properties\rcSource\right=w
dwm_thumbnail_properties\rcSource\bottom=h
dwm_thumbnail_properties\rcDestination\left=0
dwm_thumbnail_properties\rcDestination\top=0
dwm_thumbnail_properties\rcDestination\right=w
dwm_thumbnail_properties\rcDestination\bottom=h
Where X/Y are the top left desired area of the source (not of its window corner), and W/H is partial of the source window. Just can't seem to make any progress.

a wild guess:
#DWM_TNP_RECTSOURCE = $00000002
dwm_thumbnail_properties\dwFlags = #DWM_TNP_RECTSOURCE | ...
dwm_thumbnail_properties\rcSource\left = x
dwm_thumbnail_properties\rcSource\top = y
dwm_thumbnail_properties\rcSource\right = Width
dwm_thumbnail_properties\rcSource\bottom = Height
c ya,

Just testing this and was wondering if drawing the thumbnail be put on a gadget, like a ButtonGadget for clicking it? Instead of drawing it direct to a window? I tried using the GadgetID() of various gadgets but no luck.
