Yes. Some of you probably remember the release schedule message I sent some weeks back; ubuntu 12.04 will by no means include lxpanel2 and I guess the same goes for debian wheezy and both of them has 2+ years of support in the distribution level. LXPanel (hate it or not) will be around for a long time. I'll work with the recent changes and try to go to release in early January and will follow up on that release in February/March with a bug fixes focused release.

Re: [Lubuntu-desktop] [Lxde-list] About lxpanel2
If your object oriented refers to the programming language, I'm using Vala now, which is a OO language built on top of GObject/C runtime. The language itself is OO. This, however, does not mean that the program written in it will be OO. I'm not a fan of making everything an object approach. No single programming style is best for all cases. Using too much OO stuff in GObject will create extra overhead as its type system is all created at runtime. Type-casting and virtual function calls sometimes requires looking up in tables. Signal emission in GObject/C is also very inefficient, too. So basically, I'd avoid unnecessary OO whenever possible. If the term object oriented here refers to making everything on the desktop an object, that's a totally different thing and is not related to language used.

[Lubuntu-desktop] Integrate obkey (or the like)?
There is a small, fast, simple keybinding utility for Lubuntu available: http://code.google.com/p/obkey/ I wonder what the thinking might be on whether it (or something like it) should get bundled into a Lubuntu base install? With Lubuntu's new and growing popularity (I'm among the recent, grateful converts), it seems reasonable to think of small enhancements that will make the migration a little easier. There has been a fair bit of call in the Ubuntu forums for some simple GUI means of editing the applications menu, for example. Making assignments to keys is another one of those tasks that is easily done in other OS's, but non-trivial in Lubuntu. With obkey, there is already a solution to hand. It needs some documentation, but that is more easily done than the coding!

Could be quite wrong there, though, so open to correction! Also, 'Development is halted' looks scary to me. I *think* that's because it's stable and does what it's supposed to do, not because it is almost-there-but-abandoned.

Sure, but I did not receive any formal training and taught myself programming with books, other OSS projects, and, google only. So the design can be a little bit weird sometimes. GTK+ itself is designed in a fully OO way and uses a lot of design patterns, but it's written in C. However there is no language support for objects in C. We only have struct + functions. A virtual function table in GTK+ world is a C struct which needs to be filled by hand. Things does not look like OO initially, but its spirit is OO sometimes. - How do you do it?

Type-casting and virtual function calls sometimes requires looking up in tables. Signal emission in GObject/C is also very inefficient, too. So basically, I'd avoid unnecessary OO whenever possible. If the term object oriented here refers to making everything on the desktop an object, that's a totally different thing and is not related to language used.

Are you planing to make it using an object oriented approach? What do you mean by object oriented approach? I don't understand what you mean. Any examples? I THINK he means whether or not you will be using an object oriented programming model and programming language (or interpreter on the runtime or macro level), which has certain advantages (everything like programs, icons, files, windows etc. are objects where all the code needed to manage the object is included in the objects class, and not spread across different places in the code), and disadvantages (well, object oriented code tends to get voluminous and slow, maybe even buggy, at least that is the common perception). http://en.wikipedia.org/wiki/Object-oriented_programming Gnome and KDE both use object oriented models for their desktops, where KDE also uses an object oriented language, while GNOME works more with procedural languages (C) and its own object management code. Btw, for LXDE, I would, independent of that question, opt for using anything that is stable, small (in the total resources footprint) and fast, even if it means less features. I like C, even that it means you have to be extra careful about memory management and pointer arithmetics. One of the major features of LXDE for me was always that it needs less than 5 seconds to start up all necessary components (lxpanel, pcmanfm, window manager), instead of initializing a lot of services before you can do actual work on the desktop. I hope that the new versions of lxpanel and pcmanfm will still be similarly efficient, no matter which model or toolkit you will use.
