Installing MacOS X like dock bar

There are many programs that emulates the look of MacOS X. One that I liked is Avant Window Navigator. Installing it is also very easy. Just fire up Synaptic Package Manager, search for Avant, then scroll down and select avant-window-navigator.

Once it is installed, remove the bottom bar by right click on the bar and select delete panel. Then you can start Avant Window Navigator from Applications -> Accessories -> Avant Window Navigator. It is also a good idea to make Avant auto load on login. To do so, click on System -> Preferences -> Sessions. Then click on Add button. The command to run Avant is /usr/bin/avant-window-navigator. You can name it whatever you like and add description whatever you like. This is what I have on add screen.

Customizing Windows Transparency

One of the things that I really need is transparency on terminal background. If I have transparency on terminal, often times I have to copy something from spec or what not, and I don’t have to switch window. I can simply look through the background to the document I need. So naturally, transparency is next.

To setup transparency, you need to know window type, or window class type, or any other identifier for a window. Compiz will then match these criteria and adjust the window setting accordingly. There’s a very good documentation here. For my purpose, I open terminal (Applications -> Accessories -> Terminal) and the first thing I do is to change the color theme so that it is white on black. To do it, click on Edit -> Profiles. Then edit the default profile. Go to Colors tab and select White on Black on the Build-in Schemes pull down. Once you have the white on black, here’s what I did to find out what type it is.

user@laptop:~$ xprop WM_CLASS
WM_CLASS(STRING) = "gnome-terminal", "Gnome-terminal"
user@laptop:~$

Note that once I run xprop, the cursor will be changed to a big cross-hair. To identify the type of window, click on the window you want to identify. In my case, I click on terminal window.

Now that I know what type a window is, I then open Compiz Settings Manager (System -> Preferences -> CompizConfig Settings Manager). Under Accessibility section, there’s a "Opacity, Brightness and Saturation". Make sure it is checked. Then click on it to open the settings.

Under Window specific settings, click on New button. On Windows textbox, type "class=Gnome-terminal" (off course without the quotes). Then set Window values to 85. This is the opacity value. The range is between 0 – 100 with 100 being without transparency. My personal taste, I like it at 85. Once you’re done, here’s how the terminal look like.

With the same techniques, I’ve changed the opacity of some other window types as well. I have "class=Gnome-panel" and &quottype=dialog | type=popupmenu | type=dropdownmenu;" to 85.

That’s about it. I hope this article helps you. As always, I welcome comments / questions / critics that will help me and other readers understand better.
