To keep things simple, we will only create a static plasmoid which will contain the following items: Every Plasmoid needs a .desktop file to tell plasma how it should be started and what name it carries. A basic layout is created, a plotter widget is added to it, a plot is added to the plotter, and some administrivia is performed. As you can see in the example code we are using the Plasma::Svg object, there are some important things to note here. Default Widgets Learn By Example You can learn by example by reading the default widgets located at: /usr/share/plasma/plasmoids/ all that are icons when in a panel (PopupApplets) other ones as well, like nowplaying that loses pieces when it's in a panel > In addition can u tell me how i can affect a plasmoid with the location??? This not only saves you time and code, but creates a more consistent presentation for the user. Reading and writing the configuration from the plasmoid code. Plasmoids follow the simple KPackage structure. Download the plasmoid Open the file (*.plasmoid) with Ark and extract it to a directory Open Konsole and navigate to the directory from the previous step cd /path/to/directory Install the plasmoid with the command (where directory-name is the name of the extracted directory) plasmapkg -i directory-name Tip For more details on CMake please read Development/Tutorials/CMake, If your current Development Environment differs from the Test Installation, you have to run cmake with -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`.
