|In the last times all my customizations to LXDE plugins (Keyboard Layout Handler and Application Launch Bar) were accepted and so are/will be in official lxpanel versions.In the last times I worked again on a new plugin that integrates together the Application Launch Bar and the Task Bar.
The Name of this new plugin is Application Launch and Task Bar.
Here’s the interaction that I added (visible in the screenshots below):
1) when right clicking on a task button you can see the new menu item “New Instance” if its desktop file is found in launcher or in the menu cache;
2) when right clicking on a task button you can see the new menu item”Add to Launcher” if its desktop file is NOT found in launcher and is FOUND in the menu cache;
3) when right clicking on a task button you can see the new menu item”Remove from Launcher” if its desktop file is FOUND in launcher;
4) when right clicking on a task button you will see NONE of the above if the funcion was not able to locate the desktop file at all.
The way that a desktop file is searched from a task button is simple and not perfect, in some cases it may fail and there’s a config key file to handle these special cases.
a) The desktop files have an Exec section, the exec command is stripped from any argument and the location of the binary (e.g. /usr/bin) is also removed;
b) From the task buttons I retrieve the PID of the window and from the PID I retrieve the command, this command is also stripped from arguments and binary location;
c) the key file about special cases is created if not found in ~/.config/lxpanel/
which means that for the task manager retrieved command in these 3 cases I search instead for the associated value
If you are on Lubuntu 12.04 or 13.04 you just download the debian package, otherwise download the source code archive and you need to compile it yourself (be careful, the --prefix depends from your distribution!):
sudo apt-get build-dep lxpanel
./configure --prefix=/usr --enable-man --enable-indicator-support
sudo make install
After the installation you call
then add the applet ‘Application Launch and Task Bar’ to the panel and remove the ‘Application Launch Bar’ and the ‘Task Bar’.
NOTE1 about Keyboard Layout Handler: about the advanced setxkbmap options you can get a list of all options entering in a terminal man xkeyboard-config
NOTE2 about Keyboard Layout Handler: if you will create a folder in /usr/share/lxpanel/images/xkb-flags-cust (may vary according to the prefix) and put your custom country flags there, you will then have a third choice in “Show Layout as” named “Custom Image” (embedded flags are in /usr/share/lxpanel/images/xkb-flags).
