 Posted: Sep 11, 2005 6:31 Post subject: FreeBASIC Screensaver Kit |
 |
|
OK, there seems to be a lot of interest in screensavers lately, so I made a "helper" kit so people who don't want to learn the WinAPI don't have to use "dirty screensavers" that just sniff out the command line and use GFXLib.
http://www.betterwebber.com/stuff/FB_ScreenSaverKit.zip
Just unzip, and include this at the top of your program:
| Code:
|
|
#include "FB_ScreenSaverKit.bas"
StartScreenSaver
Pset (x, y), colr
'...
|
Then you can just start using Pset, Line, etc. It sets up a NULL GFXLib driver, and copies that to a window 60 times a second. If the screensaver is in preview mode, it stretches it so it fits in that little box. If you include a dialog resource called "FB_SCRNSAVE_ABOUT" it will display that and close it when the "IDOK" button is pressed, or show a messagebox if a resource isn't included.
Packaged is the kit, and a conversion of Mambazo's "Doodle" demo. Notice how the preview box and settings button work, and how there's no code related to that stuff in the actual program, FB_ScreenSaverKit.bas takes care of it all.
If you want/need a real settings box, then I might make a function where if you include a different dialog name it makes a modal dialog and lets you hook the message loop, and it doesn't save much effort unless I made a mechanism to save registry keys, which I don't feel like doing because I like registry undiddled. |

And it's too the first NULL GFXLIB example I have seen.It seems lillo forgot to write its's own....
Jofers: A feature you forgot to tell us. Startscreensaver copies the present screen to the GFXLIB buffer, so you don't need to do that if the saver "plays" with the present screen. If the screensaver does a diferent thing, just start erasing te buffer...
Great!!
EDITED: The only drawback. Windows API POINT interferes with GFXLIB's POINT, so i can't do a screen melt.... |

Yes, but you can still use the function from the runtime library:
| Code:
|
|
#define Point2(x, y) fb_GfxPoint(0, Csng(x), Csng(y)) |

Not really since it uses GDI. Can SDL/OpenGL write to ScreenPtr?
Also, if you wanted to help me with that, be my guest. |

| I don't know about GL writing to a GDI context. But I was thinking of a GL kit or something. |
