Software News   Software News : Feelin release 060207
   posted by Gofromiel on 7-Feb-2006 5:41:27 (8851 reads)
A new release of Feelin is finaly available for m68k and OS4 (MOS seams to have some bugs, I hope it will be available soon). This new release is a MAJOR update. I don't keep track of every little details (even if I should), but believe me Feelin has been GREATLY improved in EVERY aspect. Here is a short list of the most important things:





SYSTEM

It's now possible to create meta-classes. This feature was already possible since classes are also objects but now it's really working The EXIT end INIT optionnal code is now deprecated, you must create a meta-class to create/delete private data.

The memory system has been improved further more and is now even faster. The F_DisposeP() function is now deprecated since, with the new techniques, F_Dispose() finds the right memory chunk to dispose on the first try (less than 1% of missing). The developer can also tweak the memory system to enable memory walls, memory marking, custom patterns to fill new/allocated/disposed memory...

XML

Entities support has been added and is widely used. The attributes used to generate objects are now typed. XML parsing has been improved furthermore and FC_Document provides nicer methods.

EVENTS

Windows are no longer handled by the application they belong to, but a new shared object named "WinServer". This server is also an anchor for various inputs such as window events, mouse buttons and movements, key stroke... but also pophelp, timer, wbdrop... it also add special features which are not available with Intuition such as unactivable windows (usefull with menus and popups).

DAMAGED RENDERING

A new technique called "damaged rendering" is now used to redraw objects. Only objects which aspect as been modified (state, size, position) are now updated saving a lot of unnecessary renderings. I was already using a similar technique but it was costing a lot and was not as effective.

PREFERENCES, ASSOCIATED DATA, EDITOR

Preferences are now stored in CSS files instead of an IFF ones. FC_Preference is now a subclass of FC_CSSDocument. The whole preference system has been updated and is more compact and nice.

A new technique called "associated data" is now used to skip decoding over and over the same preference items. To put this short, a window with 1000 buttons was resolving and decoding 1000 times the "$button-frame" item to setup the frame of the SimpleButton objects. Now a "complex data", which is the decoded stuff of the "$button-frame" contents, is associated with the "$button-frame" item. Thus, the preference item is now resolved and decoded once, saving 999 resolving/decoding.

This technique is currently used for frames and backgrounds but will soon be extended to fonts, color schemes...

The preference system as been widely rewritten for this purpose.

The "ModulesList" shared object is now used to keep an eye on classes. It handles various lists and is now used to load classes embending a preference group. The launching of the preference editor is now very fast. This shared objects also maintain a list of the decorators available, which is used to create dynamicaly the "Decorators" preference group.

ALPHA BLENDING

FC_CorePNG has been created to decode PNG files without using datatypes, saving time and embended alpha information, which is fully supported by FC_BitMap. FC_Render also support alpha-blending but is currently limited to rectangles. Thanks to alpha-blending, you can create even nicer applications.

COLORS AND IMAGES

Colors are now defined as in CSS e.g. "#FF0000" for full red or "shine" for the FV_Pen_Shine entry of a color scheme. All image specifications are now in XML format, many of them have been extended e.g. gradients can be defined using 2, 3 and even 4 colors (aqua style).

Nice :)

It's just too bad it wasn't released last week, for Hombre to be able to perform his Feelin presentation, held last weekend in the INP party in France, with this new version.

Definitely a system worth looking into.

Nice work!

Even as I prevere Reaction for classic apps, I see the future for feelin in e.g. mediaplayers. BTW an AmigaOS4 skin would be beautyfull!

@Ashitaka

A lot of the demos seem to crash, but that might be my fault. Anyone else has this problem ?

Overall, I am really really impressed, this feels very responsive, fast, and looks cool :) Excellent stuff.

Wow, this looks very nice. I never realized that there was a native OS4 version. Thumbs up for that, thank you for the effort.

Any chance you could include Feelin on the OS4 CD as a contribution?

Am I the only one that does not like the idea of having yet another GUI system available?

Feelin seems to be an impressive product, no question about it - but the Amiga is more than twenty years old and never had a standard GUI toolkit: Intuition, Intuition vs. custom GUIs, Intuition vs. Gadtools vs. custom GUIs. In the mid-nineties MUI, Reaction, BGui and Triton arrived, half of my commercial applications still use some proprietary Gadtools extensions...

I was actually looking forward to having only two GUI systems available to developers, with both of them being powerful enough to stop coders from writing their own versions.

Normally I would agree with you... However, every Amiga GUI toolkit I came across had a certain degree of SUCKism to it. Too limited, too complex, too slow, etc. I am still waiting for one that I actually like...

My personal opinion of course :)

@rogue:
Does is mean that Feelin hasn't the level of 'SUCKism' you've find on others and that you're rather found on it!? Or that you're still waiting to Yet Another GUI System?

Who knows? At the moment it is quite crash-prone (at least here, most of the demos just burn) but then it's under development.

Dumb question: How to install Feelin?

Certainly packed with features, and looks the business. I will download it and have a bash under UAE in a little while.

I've tested the previous version (on OS3.9) and some of the demos are really amazing!! I'm impressed!
I love the ability to customize with CSS.

Possibly it takes still time until it's really useful, but the WinServer-thing sounds interesting. What are the advantages? I could thing of two: faster with more programs/tasks and probable useful for distribution and terminal-alikes.
