Hi,
i have a bug with the tasklist. I post it here or do you prefer another place for bug reports?
Problem seems to occur when the window title contains those masked html stuff (how do you call that?) like Ü or — (i.e. on http://caw.milkbox.net/). The title line is pushed down.
Strange enough, when i wanted to take a screenshot of firefox with http://caw.milkbox.net opened, the bug was gone. So i took the screenshot of a local copy of "Documentation for CAW! — CAW! v.9 documentation.html", where it still exists as long as the — is in the title tag. After that, i reopened http://caw.milkbox.net and, well, the bug was back there. I really don't know...
http://omploader.org/vMjZtZw/caw_title_bug.png
My config.py (expires 2009-08-23 10:56:15) , using caw-git 20090820.

I hate to say it but I think this is a font issue. If you use a different font this problem goes away. The origin of the problem is that -- is actually a UTF8 character that snap doesn't want to display. I have the same problem with all fonts that are similar (mintsstrong, nu) and I'm not sure why.

Rich, as a comparison I loaded up PyPanel with the same font. It doesn't even display the text properly (ie. doesn't display utf8 characters). Tint2 displays it fine and I'm not sure what they are using to layout their text. It looks like tint2 *is* using pango, so I'll dig through their source a bit and see if there is something I'm missing. BUT, I think they are using xft+pango, not cairo+pango which is what CAW is using. I'll see if I can fix this, but for the time being my suggestion is to using a different (more utf8 friendly) font. That's not much of a solution!

Huh,

that's kinda sad. I went so long with that font. Well, who cares. Welcome Terminus, my new true love.

one of use should write to artwiz and see if they can get updated...

Added an mpd widget (mpdc)

/bump to see if anyone is still giving this a workout and if they've run into any problems...

I've intended to add icon support to the taskbar and to give some launcher plugins but I haven't gotten around to it atm.

rizzix · 2009-09-03 06:12:37

Oh this is wonderful! Is there anyway you can add support for displaying piped in text, as in dzen2 or xmobar?

rizzix · 2009-09-03 20:38:37

Ah well, using FIFO I've managed to get the desired behaviour. However its unfortunately monocoloured.

two possible options: 1) use multiple fifos. 2) I'll add an option to use pantos markup language. That way I don't have to write a text parser and you can get your multicolor IO.

I'll add the option sometime tonight and you can give it a shot later.

I'll warn you it's not the best markup in the world (read XML like) but I don't wan to get into the parsing business for performance reasons.

linkmaster03 · 2009-09-04 02:31:44

This looks really awesome. If I was still using Openbox and not dwm, I'd probably replace tint2 with this. Keep it up!

Chokkan · 2009-09-04 09:51:43

I'm using it on my netbook. I've been trying it without a taskbar and you know, it's totally fine. I don't really miss it at all. I'm a convert.

If I want to keep an eye on network traffic when I'm using my USB modem, how would I go about it?

rizzix · 2009-09-04 21:19:09

caw tends to crash now and then on my laptop because of a div-by-zero exception.

It has to do with the battery widget. In some cases the `rate` is reported to be 0. I have no idea why, but it does happen. Could you add a check to see if the rate is zero then set it to 1 or something.

In particular the exception occurs at line 92. However this check could be added everywhere timeleft is calculated.

I'm using musca wm with an nvidia card and seperate displays (no twinview or xinerama). How can I launch CAW on both displays or a specific display?

The "DISPLAY=0.0; caw" did not work.

Crows · 2009-09-11 18:00:11

I've been using CAW for a while now - great little panel. Thanks!

A few quick observations:

1) Some kind of command-execution for the battery widget would be nice. So you could get it to notify you on warn_battery, say. (I hacked together an imp of this in about three lines, but I'm sure it could be done better by someone with more programming knowledge).

2) When my battery reached 100% it gets displayed as =117= and just generally doesn't appreaciate it much. Any thoughts?

3) Quick feature request: how about adding Awesome-style desktop list stuff. So if you're using all desktops for the widget it will graphically display which of them has open windows. Maybe underlining or a different color?

2 likely reasons for that:

1) you don't have a battery in your machine. Remove the battery widget from config.py.

2) Your battery is under a different name. Most likely BAT1 - try that in config.py instead of BAT0.

Ok, I disabled all widgets that I don't need, but I want to keep the volume widget.
Sadly I get this error:

Do I have to use OSS? Or Is there a way to use the widget with alsa?

That's odd, I use alsa. Did you set vol = Volume(device='PCM') ? (You don't have to use PCM, it a personal preference)

Btw, any plans to add a "keyboard layout" widget?

PS: And where can I get that 'mintsstrong' font which is offered by config.py?

artwiz-fonts to get the mintsstrong font

Mr.Cat · 2009-10-21 17:56:46

Aha, thanks. Nice fonts, but seems they all lack cyrillic letters unfortunately.

By the way. I'm trying to switch from openbox to xmonad. How would I run caw in xmonad?

UPD: Made it work via ManageDocks, but caw fails to show tasklist (other widgets I use work fine):

1. Clicking on task list does not work: gives something like "Bad Match: 12582938 42"
2. Tasklist shows "minimized to tray" windows (like pidgin contact list).
