Graphic Static

[digelo]

Hi

I wanna make that static controls in my application and be able to change its colors and size, Can somebody help me in this?

    You must subclass it or use your own user defined class and process the messages needed to show those  counters. I'm going to work something out and post later. Ok? Thanks for letting me help. Got to get my hands back on ASM.

Thank you , any help would be most welcome

For a 7-segment style display, without a scalable 7-segment font the size change will be difficult.

Sounds like a nice little project. LUTs, CreatePolygon, FillRgn, ... ;-)

i would probably use StretchBlt and draw my own   :P

I doubt that StretchBlt would produce good results. I think drawing the digits as a collection of polygons could produce good results, but doing so would be difficult.

well - it isn't quite clear what he wants
he says he wants "...able to change its colors and size"
but, he doesn't really say if he wants that on the fly or case-by-case

even so - StretchBlt will do fairly well if you SetStretchBltMode to HALFTONE and SetBrushOrgEx

For a Windows program I would not bother with any sort of N-segment display. They were a good development in their time, and there are still good reasons to use them for certain applications, but why accept their limitations when you don't have to.

If you want to draw to the static control you have to use GetWindowLong and change the default procedure address. I cant find any easy way to that directly without changing the control procedure.

That was fiddly ... in the attachment an example (GDI) that may be used as a base.

EDIT upload: some changes to reduce CPU usage . Also WM_DESTROY was not process by the control.
EDIT2: Further improvements

The attachment contains a quick and dirty test app. I can't see any effect from SetStretchBltMode and SetBrushOrgEx, perhaps because I'm doing something wrong, but even so StretchBlt does much better than I thought it would.

Correction, I can see an effect, but I have to capture the window and zoom it up. The effect does improve the image quality, but it is present only when the size is reduced, and for the best quality you need to be working with a 24-bit bitmap. So it looks like the way to do this is to create the digit bitmap at the largest size, and reduce the size as necessary. The second attachment contains a sample of the result.

That is a great example :t

Did it drawn on each static control like he want? I see you use a timer for trigering the drawing.

Hi qWord,

well written example.  :t
