Graphics question

[Thomas Larsen]

By the way, I forgot to mention: modules/plugins should have some kind of internal "exit" function which is called when Yabasic exits. In the case of the SDL module above, it would close any open windows and perform other similar tasks; in the case of a Curses module, it would return the window to standard input-output mode; and so on. The exit function corresponding to every module/plugin loaded by Yabasic would be called when Yabasic exited.

First this thing dont look logical to me

module "sdl" as sdl

maby :

Code:

module "sdl" As Gui
or
module "win" As Gui
or
module "gtk" As Gui

and ...

red = sdl.openwindow (100, 100, "Red Circle")

whay not ...

Code:

sdl.openwindow (red,100, 100, "Red Circle")
....
red.color (255, 0, 0)
red.circle (50, 50, 25)

of course your way reminds me on
hwnd = CreateWindowExA ....  win api function
which is ok for me

Code:

module "sdl" As Gui
or
module "win" As Gui
or
module "gtk" As Gui

Any of these would be possible. The "as ..." part would simply specify an "identifier", or prefix, for the module.

whay not ...

Code:

sdl.openwindow (red,100, 100, "Red Circle")
....
red.color (255, 0, 0)
red.circle (50, 50, 25)

I'm not sure how this could be done easily without making complicated alterations to Yabasic, because I envision openwindow () returning a unique numerical identifier (like open () does) which could be used to reference the newly-opened window. For example:

Code:

module "sdl" as gui

dim windows (10)

for open_windows = 1 to 10
   windows (open_windows) = gui.openwindow (100, 100, "Window Number " + str$ (open_windows))
next

Does that make sense?

Cheers,
Thomas

i think smfl is the best option, because there you have some Network features too.

Has it been decided yet whether to use the old graphics commands or go the "functions" route ? Having had a quick look at a plugin for SFML, I can see where Thomas is coming from, and how it could make life a lot easier for Psnake.

I probably wont get to attempt an SFML plugin, at least in the near future, but can see where the "functions" route would allow a relatively painless addition with it's own commands.

Don't see any need for backwards compatibility, we've all got the old Yabasic binaries to run older programs.

Edit: Just corrected my grammar.
