Plasmoids follow the simple KPackage structure. # See http://api.kde.org/ecm/manual/ecm.7.html, # and http://api.kde.org/ecm/manual/ecm-kde-modules.7.html. Purchase books, mugs, apparel, and more to support KDE. Purchase books, mugs, apparel, and more to support KDE. To keep things simple, we will only create a static plasmoid which will contain the following items: An SVG Image Icon Some nice text The Code The .desktop file Every Plasmoid needs a .desktop file to tell plasma how it should be started and what name it carries. In this example, we're going to be writing a plasmoid that shows your laptop's battery charge in a neat graph as time goes by. To get a list of installed Plasma packages call, Pick one of those lines of your choice and run for example. Creating keyboard shortcuts Open a console Access another computer's display Change the color of the blue folder icon Mouse pointer settings for large displays Localization Settings We are going to create a simple plasmoid in this tutorial. Input Method Panel Right click desktop, choose Add Widgets, place the Input Method Panel plasmoid wherever you prefer. We split the contents into subdirectories: config, data and ui to make things easier. # Needed by find_package(KF5Plasma) below. There is some python wrapper code (in /usr/lib/python2.5/site-packages/PyKDE4/plasmascript.py) that needs to work some magic so your python script can access protected Plasma::Applet members. Comments have been added in the code for clarity. In either mode, Plasma::Svg can be used to draw a subset of the SVG file by passing it an element id that appears in the SVG document. It allows easily the declaring of an interface and to easily create things like ListViews with native Plasma theming. You also set the start size in the constructor. If your current Development Environment differs from the Test Installation, you have to run cmake with -DCMAKE_INSTALL_PREFIX=$KF5. By adding setBackgroundHints(DefaultBackground) to the code, the default Plasma background gets drawn behind your plasmoid. . Purchase books, mugs, apparel, and more to support KDE. first which will speed things up. This is now the recommended method of creating plasmoids, where possible. If successful the applet can be installed by running sudo make install. To keep things simple, we are going to make have use QML 2.0 and it will use Plasma Components in our tutorial . As mentioned earlier, the plasmascript module contains some magic bridge code that lets you access protected members while python thinks you're outside the Applet class. and run kbuildsycoca5 (so that KDE apps will know about the new desktop files). A problem with mixing Python with Qt's signals is the lack of type safety. Content is available under, Getting Started With Plasmoids..Some more, https://projects.kde.org/projects/kde/kdeexamples/repository/revisions/master/show/plasma/python, Use SVG artwork in the simplest way possible, Creating a Plasma Activity Template Quickstart, https://techbase.kde.org/index.php?title=Development/Tutorials/Plasma4&oldid=84767. Applets can say in their metadata desktop file what features they provide: this is use to build an UI to switch an applet at runtime with other applet that provide the same feature. A basic layout is created, a plotter widget is added to it, a plot is added to the plotter, and some administrivia is performed. For this example, our plasmoid will be called 'powerchart'. ===== A Plasmoid is a widget that can be loaded into Plasma that uses the native Plasma API and comes packaged in a single archive file that includes the code, metadata, images, configuration definitions, etc. In there someone send me for me to start working on my plasmoid, but been honest, that's not Press J to jump to the feed. We are going to create a simple plasmoid in this tutorial. Content is available under, K_EXPORT_PLASMA_APPLET ( , ), dataUpdated(const QString &source, const Plasma::DataEngine::Data &data), Determine the applet size and geometry: geometry() and contentsRect(), // Here we avoid loading the header multiple times, // The paintInterface procedure paints the applet to screen. KDE Frameworks >= 5.73, KDE Plasma >= 5.19 (Kubuntu 20.10 . Plasma is shipped with preinstalled modules in your root directory /usr/share/plasma/, however you can also download themes/widgets to the user's home directory ~/.local/share/plasma/. You can see a list of available image components on the Plasma Theme page. The KDE wiki has a Getting Started and Hello World tutorial which you can read as well. With the odd exception of self.applet, everything else works like normal. Instead of plasmawindowed you can also use plasmoidviewer (in the plasmate repo): For testing an installed Plasmoid, the --applet parameter takes the X-KDE-PluginInfo-Name of the plasmoid in its .desktop file. In order to test your Applet you can use the plasmoidviewer program: You can even view your Applet in a small desktop using plasmoidviewer: Where applet_name is the value specified into .desktop for the X-KDE-PluginInfo-Name key. This can be considered the main function since it paints the plasmoid on to the screen. In the above example, the minimum width will be the height in case the formFactor is Horizontal .Similarly , if the formFactor is Vertical then minimumHeight shall be the width as shown in the above example . In our dataUpdated method, we find the data we want, pry it out of the Qt code, and put it in our plotter's chart. As discussed in the main.qml setup widget section, when you import org.kde.plasma.plasmoid 2.0, the main Item in your widget will have the Plasmoid (with a capital) property group similar to when you import QtQuick.Layouts 1.0.This Plasmoid property group has properties from AppletInterface which inherits a few properties from PlasmaQuick::AppletQuickItem. Another problem is the use of QStrings. Oct. If we wanted to setup the clock to have the seconds hand by default, the script will located at: The file name of the setup script for the plasmoid is the same as the plugin name, so, for instance, the file for the analog clock will be called org.kde.plasma.analogclock.js. Congrats! It allows easily the declaring of an interface and to easily create things like ListViews with native Plasma theming. Then run make. Your directory structure should now be as follows: Every Plasmoid needs a .desktop file to tell plasma how it should be started and what name it carries. # Use Extra CMake Modules (ECM) for common functionality. Content is available under. In contrast, the sysmon can show any metric provided by the System Monitor data source engine. where the files CompactRepresentation.qml and FullRepresentation.qml exist in the plasmoid package. In the constructor you only tell plasma about the background and configuration file if any. If you would like to connect to any of Plasma's DataEngines, you can implement the dataUpdated method in your Plasmoid. #Needed once to let KDE know there is a new plugin, https://techbase.kde.org/index.php?title=Development/Tutorials/Plasma5/QML2/GettingStarted&oldid=105983, the packaged version of your plasmoid, such as. You can install your plasmoid into ~/.local/share/plasma as described in this section, though obviously this is just temporary. To do all of that, run this one. main.py - The plugin's code. Using this function gives your application a chance to cleanup before quiting. As a good example, if you open the clock.svg file that ships with the default theme, you will see that it has a background, 3 needles (hour, minute and seconds) and a foreground (the glass). If not, your applet will fail to load and you'll be puzzled why. In the top-most folder there should be a file titled metadata.desktop and a single folder called "contents". Installation is pretty simple and straight forward: Hope they could make it an official kde plasmoid one day. It expects our main code file to contain a CreateApplet method that returns our plasmascript.Applet class. It makes things take a little more typing but it doesn't add a whole lot more effort. We are going to create a simple plasmoid in this tutorial. hello i'm trying to run the hello-python tutorial from http techbase kde org development tutorials plasma python gettingstarted i've created all the files and dir structure and packaged it with .

The Device Notifier is used for handling pluggable devices such as USB pendrives (also called flash drives or thumb drives), digital cameras, external USB hard drives, etc. Plasmoids that use the QML (aka QtQuick) declarative language to describe their user interface while having the logic of the applet, in JavaScript (QML is essentially a forge between CSS and JavaScript). There are some sample plasmoids written in python https://projects.kde.org/projects/kde/kdeexamples/repository/revisions/master/show/plasma/python. KDE Plasma Desktop (sometimes known as KDE, the organization that publishes it) is a Linux-based desktop and application platform. Plasma expects a certain set of files and directories to exist when loading a plasmoid package: metadata.desktop contains the plasmoid's metadata such as its name, author, and scripting engine. First and foremost, make sure you have Python support enabled . It should have a .plasmoid extension. When your application is unable to start, this function allows you to inform Plasma and give an optional reason why. You can call your file anything you want, but a good naming scheme is -.plasmoid eg powerchart-pre0.1.plasmoid. This tutorial covers the Simplified JavaScript API for Plasmoids See the SystemTray container for an example. A Plasmoid is a widget that can be loaded into Plasma that uses the native Plasma API and comes packaged in a single archive file which includes the code, metadata, images, configuration definitions, etc. For more details on CMake please read Guidelines_and_HOWTOs/CMake, The plasmoid can provide two components: compactRepresentation and FullRepresentation. The first thing you do in a python file of course is import your dependencies: The last import contains the bridge between your python code and the underlying C++ API. See tweets, send tweets, and check mentions. This not only saves you time and code, but creates a more consistent presentation for the user. I'm writing my first KDE plasmoid using QML. Our applet class is all written. Avoid calling geometry() and size() because they don't take into account the margin's size set by the applets default background. It is what Plasma is leaning the most towards, especially in the Mobile, MediaCenter shells. It is possible to use . . 1.2 Apps, Widgets and Plasmoids? If a fullRepresentaion is defined, the root item will not contain any graphical element (they will be never shown) but is only supposed to contain models and data that must be accessible from both the compact and the full representation. import QtQuick 2.9 import QtQuick.Window 2.2 import QtQuick.Controls 2.5 import QtQuick.Layouts 1.11 //import org.kde.quickcharts 1.0 as Charts import org.kde.plasma.core 2.0 as PlasmaCore import org.kde.plasma.plasmoid 2.0 import org.kde.plasma.components 3.0 as PlasmaComponents // naimportujem si vecky vobkty ze sloky 'cudliky' import .
