Fireworks Screensaver 1.0 Beta 3 - "100% CLEAN" AWARD

I'm gonna use this one myself, I love it! ;D

BTW: It would be nice if you would report your FPS, i'm getting 48 at default settings, and 800-1000 on 0 delay.
And does the preview and config work on all windows versions?

Hi Joakim, I'm getting 44 FPS on a Toshiba P4 3GHz laptop (graphics: NVidia GeForce FX Go 5200). Thanks alot for showing.

One of the best 2D Plot()-only fireworks I have seen Looks fascinating ... N1

[edit]a screensaver should exits when any key is pressed (except the keys which
are used of course) - just my opinion :roll: [/edit]

Very nice job, JLC! I like it. But it isn't playing in the preview window? Just in main saver mode.

[dracflamloc]

That preview mode is hit or miss with screensavers.

That preview mode is hit or miss

No, it isn't. Implemented correctly it is completely reliable. But there are a couple (very easy) bases you have to cover or you'll have problems.

[Joakim Christiansen]

I didn't implement a preview mode yet, if there was a easy way where I could just scale the screen or something then it would be cool.

a screensaver should exits when any key is pressed (except the keys which
are used of course) - just my opinion :roll:

I'll try to make it that way then!

[dracflamloc]

Yea I always tap the "windows" button when i deactivate teh screensaver. I rarely touch the mouse.

[Joakim Christiansen]

Dracflamloc, done!
Now any other key closes it, just download it again!

Now I have to pounder with the preview stuff, booooring...

[dracflamloc]

Cool stuff. Pretty similar to the one most linux distros have!

[Trond]

Terrific.

[dracflamloc]

A request though: Can you please have it not change the screen resolution and also work with dual monitors?

How to do the screensaver preview window
===============================

1. Get your DisplayHwnd from the ProgramParameter
2. Open a window with the #WS_CHILD style and set parent to DisplayHwnd
3. OpenWindowedscreen with AutoStretch set to 1.
4. Set your WindowCallBack to the proc shown

Code: Select all

Procedure PreviewCallback(hWnd, Message, wParam, lParam)
  Select Message
    Case #WM_CLOSE
      End
  EndSelect
  Result = DefWindowProc_(hWnd, Message, wParam, lParam)
  ProcedureReturn Result
EndProcedure

; Once you've determined that it's preview mode and you
; have the PreviewHwnd, do this:

GetClientRect_(DisplayHwnd, @PSize.RECT)
OpenWindow(0,0,0,PSize\right,PSize\bottom,"",#WS_CHILD,DisplayHwnd) 
OpenWindowedScreen(WindowID(0),0,0,width,height,1,0,0) 
SetWindowCallback(@PreviewCallback())     

Then just run your display code normally.

IMPORTANT:
Screen width and height are the same for preview and main display. You will get automatic scaling with the Autostretch parameter
set to true in your OpenWindowedScreen() command, so if your main saver window is 1024*768, open the windowed screen that same size.

Note that you're not processing PureBasic Events in the callback, you must ProcedureReturn the DefWindowProc.

Thank you netmaestro, i'll see what I can do!
