Internal List Object Beta

[LB]

Jax made a great object called the List & Set II Object, but it was mainly for mathematical purposes and not an actual list object replacement. The List object itself is slow when you need to be fast because it, being a Windows control, likes to redraw when you modify it. Even when it is set to invisible, it still takes time to modify the list.

That is why I made the Internal List Object - it is much much faster than the List object and it has some the same features. It's in beta now because I want to find the issues before I finish the rest of it.

You can download the current Beta here: http://www.LB-Stuff.com/MMF2/Extensions/InternalList_BETA.zip
Make sure to check the example and see how the list object compares to this extension.

Please test it and let me know of any issues or missing features it may have.

Very Good, can you convert this to flash runtime ?

[LB]

Maybe in the future, but I have to learn some Actionscript first.

Thanks LB, great extension. I was going to make this myself because I needed it for a project of mine, but it seems you've saved me the hassle. I can make an icon for it if you want me to.

[LB]

Sure, I've never been good with graphics... :crazy:

Just so everyone knows, I'm nearly done adding saving and loading features with both files and strings. You can use custom delimiters (not just the new line character) and custom escape characters should the delimiter or escape character already be in an item.

If there are other request besides sorting (which I will do) please let me know.

Hi LB,

Thank you for clarifying that. There are some features which list object lacks for instance the ability of aligning its content to center and right not even with the Unicode version. It would be nice to have that feature. It would be superb if it could be ported to Unicode too.

[LB]

Unicode maybe, but text alignment...? This extension is intentionally designed NOT to make a visible list; it's all inside the extension. Anyway, you can easily fake it because in the next version I have an option to get the list as a string, and you can put it in a string object and set up the interface any way you like. Here is an example I did just for you:

EDIT: Update and timing

I modified the example MFA to test the times for precise milliseconds (thanks to TimeX object) and here are the results:
Visible List Object: 9266 ms / 9.3 seconds
Invisible List Object: 3666 ms / 3.7 seconds
Internal List Object Extension: So fast that it was less than 1 ms (TimeX gave me 0 ms)
Internal List Object with 1,000,000 loops: 967 ms

Here is the latest beta of the Internal List Object:
http://www.LB-Stuff.com/MMF2/Extensions/InternalList_BETA.zip
New features:
-Save and Load to/from files with custom item delimiters and escape characters
-Expression to get list as a string with custom delimiter and escape character, and an action to load a list from a string in the same fashion.
-Delimiters and escape characters can be more than one character long
-Miscellaneous changes (beta dialog box is gone, the extension is more stable)

I think it is fair enough. And this is going to speed up a
lot of applications. I will be using this a lot for sure.

Thank you!

[LB]

The extension is done, it just needs the icon. [size:8pt]*pokes Jaffob*[/size]

I am very grateful to Pharanygitis, who has asked to port the extension to flash.

[Fernando]

Very nice extension!!!

Good work!!!

just one mention:

if you don´t fill the escaped char when save the list (for instance "") its never ends.
