Get window title using python?

Question

I am trying to write a python program that checks every X seconds if there is a “window title” for “last.fm” ( http://www.last.fm/download ) if it did (or is this the first time I run the program ), he should use the string captured from the window title to search for lyrics and display them to the user.

I am currently using KDE4 as my desktop environment and I just need to “point in the right direction” on how I can capture the line that belongs to the window title for the last.fm client.

Thanks!

Answer 1

You can use the wmctrl utility through the subprocess module. You can enter wmctrl -l into the terminal and see the output you can get from it.

Answer 2

I think that with the help of an automation system you can achieve this as a subset. for example, try dogtail ( https://fedorahosted.org/dogtail/ ), it can focus on windows by name, click on buttons by name, so in src code you can see how to get the name.

Check out the X11 utilities, specifically xlsclients and xprop .

As an example, these are the shell commands that I used to get information about my firefox window:

 id_=$(xlsclients -al|grep "Command: firefox-bin" -A1 -B4|head -n1|cut -d ' ' -f 2|tr -d ':') xprop -id "$_id" 

Output:

 SM_CLIENT_ID(STRING) = "1181f048b9000125508490000000037360008" WM_CLASS(STRING) = "firefox-bin", "Firefox-bin" WM_COMMAND(STRING) = { "firefox-bin" } WM_CLIENT_LEADER(WINDOW): window id # 0x0 _NET_WM_PID(CARDINAL) = 4265 WM_LOCALE_NAME(STRING) = "no_NO" WM_CLIENT_MACHINE(STRING) = "gnom.ifi.uio.no" WM_NORMAL_HINTS(WM_SIZE_HINTS): program specified size: 10 by 10 WM_PROTOCOLS(ATOM): protocols WM_DELETE_WINDOW, WM_TAKE_FOCUS, _NET_WM_PING WM_ICON_NAME(STRING) = "firefox-bin" _NET_WM_ICON_NAME(UTF8_STRING) = 0x66, 0x69, 0x72, 0x65, 0x66, 0x6f, 0x78, 0x2d, 0x62, 0x69, 0x6e WM_NAME(STRING) = "Firefox" _NET_WM_NAME(UTF8_STRING) = 0x46, 0x69, 0x72, 0x65, 0x66, 0x6f, 0x78

Try using dcop and pilot kwin. You can probably list all the window names.

The following is an example of using dcop: http://docs.kde.org/stable/en/kdegraphics/ksnapshot/dcop.html

Answer 5

another answer is perhaps to check if the application publishes a song change to DBus. if so, you can just listen to the event and act on it.
