| <tt>libKF5Plasma</tt> provides the Theme class so Plasma elements and other applications, such as KRunner, that need to graphically hint or theme interface elements. This is not a replacement for QStyle, but rather provides standard elements for things such as box backgrounds.
| | this page was moved to https://develop.kde.org/docs/plasma/theme/theme-details/ |
| | |
| This allows for easy re-theming of the desktop while also keeping elements on the desktop more consistent with each other.

| |
| | |
| == Theme Location, Structure and Definition ==
| |
| Themes are stored in respective subfolders of {{path|share/plasma/desktoptheme}}. A theme is described by a '''metadata.desktop''' file in the top-level directory of such a subfolder.
| |
| | |
| Beneath this directory one will find the following file structure:
| |
| | |
| * '''colors''': optional a configuration file defining a color scheme that blends well with the images
| |
| * '''dialogs/''': images for dialogs
| |
| * '''widgets/''': images for widgets
| |
| * '''opaque/''': optional directory containing images appropriate for non-compositing environments
| |
| * '''translucent/''': optional directory containing images appropriate for when background contrast and blur effect is supported
| |
| * '''wallpapers/''': wallpaper image packages
| |
| | |
| == Theme Metadata ==
| |
| | |
| The contents of the '''metadata.desktop''' file might look like this:
| |
| | |
| <syntaxhighlight lang="text">
| |
| [Desktop Entry]
| |
| Name=Electrostorm
| |
| Comment=Brings a very dynamic electrical energy atmosphere to the desktop
| |
| | |
| X-KDE-PluginInfo-Author=A Plasma Theme Designer
| |
| | |
| X-KDE-PluginInfo-Name=electrostorm
| |
| X-KDE-PluginInfo-Version=0.1
| |
| X-KDE-PluginInfo-Website=
| |
| X-KDE-PluginInfo-License=GPL
| |
| X-Plasma-API=5.0
| |
| </syntaxhighlight>
| |
| | |
| The '''X-KDE-PluginInfo-Name''' entry should match the name of the sub-folder in {{path|share/plasma/desktoptheme}} where the SVG files for this theme exist.
| |
| | |
| If the theme should inherit from another theme than the "default" one, this can be defined by a section like this (where the folder name resp. the X-KDE-PluginInfo-Name would be passed as value):
| |
| <syntaxhighlight lang="text">
| |
| [Settings]
| |
| FallbackTheme=oxygen
| |
| </syntaxhighlight>
| |
| | |
| If you do changes to SVG files in your theme, make sure to '''update the version number X-KDE-PluginInfo-Version''' so Plasma can properly refresh its cache.
| |
| | |
| If your theme is not fully opaque, to improve readability of text or other elements, there are two options to ask the window manager to apply some effect for (KWin supports those):
| |
| | |
| a) One is adding some contrast to what is behind windows, panels or toolt ips (disabled by default), which is done by a section like this:
| |
| <syntaxhighlight lang="text">
| |
| [ContrastEffect]
| |
| enabled=true
| |
| contrast=0.3
| |
| intensity=1.9
| |
| saturation=1.9
| |
| </syntaxhighlight>
| |
| b) The other option is blurring what is behind windows, panels or tool tips (enabled [sic] by default), which is done by a section like this:
| |
| <syntaxhighlight lang="text">
| |
| [BlurBehindEffect]
| |
| enabled=false
| |
| </syntaxhighlight>
| |
| | |
| == Image Access ==
| |
| Theme elements are accessed by path. Whether this maps to literal paths on disk or not is not guaranteed and considered an implementation detail of Plasma::Theme.
| |
| | |
| Therefore, to access the dialog background, one might create an SVG in this manner:
| |
| | |
| <syntaxhighlight lang="cpp-qt">
| |
| Plasma::Theme theme;
| |
| QSvgRenderer svg(theme.image("dialogs/background"));
| |
| </syntaxhighlight>
| |
| | |
| It '''is generally recommended''' to use Plasma::Svg instead of QSvgRenderer directly, however. This is because Plasma::Svg uses caching where it can. Remember to call resize() on the Plasma::Svg before painting with it!
| |
| | |
| <syntaxhighlight lang="cpp-qt">
| |
| Plasma::Svg svg("dialogs/background");
| |
| svg.resize(size());
| |
| </syntaxhighlight>
| |
| | |
| == Wallpaper Access ==
| |
| | |
| Themes may optionally provide wallpaper image packages to be used with the theme. These wallpaper image packages must appear in the {{path|wallpapers/}} directory within the theme.
| |
| | |
| A theme may also define a default wallpaper image, image size and image file extension to be used in conjunction with the theme. It will then be automatically used as wallpaper image, if the current wallpaper type supports the settings (like the "Image") and the user has not yet chosen a custom image.
| |
| The default wallpaper image may either be installed in the standard location for wallpaper image packages or may be shipped with the theme itself. The default wallpaper image settings should appear in the theme's '''metadata.desktop''' file and contain the following entries:
| |
| | |
| <syntaxhighlight lang="text">
| |
| [Wallpaper]
| |
| defaultWallpaperTheme=<name of default wallpaper package>
| |
| defaultFileSuffix=<wallpaper file suffix, e.g. .jpg>
| |
| defaultWidth=<width in pixels of default wallpaper file>
| |
| defaultHeight=<height in pixels of default wallpaper file>
| |
| </syntaxhighlight>
| |
| | |
| == Reaction to Theme Changes ==
| |
| If you use Plasma::Svg, changes to the theme are automatically picked up. Otherwise, you can connect to the <tt>changed()</tt> signal in the Plasma::Theme class. This signal is emitted whenever the theme is changed, which may be triggered by the user switching the theme used or system changes such as a composite manager becoming available.
| |
| | |
| == Colors ==
| |
| | |
| The colors file follows the standard Plasma colorscheme file format and allows a theme to define what colors work best with its theme elements. The colors in this file can be edited with the default color scheme module.
| |
| *Make a new colorscheme using the editor in SystemSettings>>Appearance>>Colors.
| |
| *Save it with a unique name.
| |
| *Open the colorscheme in a text editor, like Kate.
| |
| **Saved at /home/[user]/.local/share/color-schemes/[unique name].colors
| |
| *Copy everything to your Plasma theme colors file except the "[ColorEffects:Disabled]" and "[ColorEffects:Inactive]" sections.
| |
|
| |
| | |
| The most common use of the colors file is to ensure that text is readable on various backgrounds.
| |
| | |
| Here is a list of color entries in the colors file that are currently actively used in a Plasma theme:
| |
| | |
| * '''[Colors:Window]'''
| |
| ** '''ForegroundNormal''' the text color applied to text on the standard background elements; maps to Theme::TextColor
| |
| ** '''DecorationHover''' the color used for text highlighting; maps to Theme::HighlightColor
| |
| ** '''BackgroundNormal''' the default background color, for items that paint a background themselves, allowing them to blend in with the theme; maps to Theme::BackgroundColor
| |
| * '''[Colors:Button]'''
| |
| ** '''ForegroundNormal''' the text color to use on push buttons; maps to Theme::ButtonTextColor
| |
| ** '''BackgroundNormal''' used for hinting buttons; maps to Theme::ButtonBackgroundColor
| |
| ** '''ForegroundActive''' color used to tint BackgroundNormal for final button hinting color
| |
| * '''[Colors:View]'''
| |
| ** '''ForegroundLink''' clickable text link font color
| |
| ** '''ForegroundVisited''' visited clickable text link font color
| |
| | |
| Other colors in the file may be used by individual widgets or used in the future, so it doesn't hurt to provide a complete colorscheme file and is probably a safer strategy.
| |
| | |
| Currently also used by individual widgets, which should give a good idea of additional usage patterns:
| |
| | |
| * '''[Colors:View]'''
| |
| ** '''ForegroundActive''' used by the digital and fuzzy clocks for the default text color, dictionary widget for results text, microblog for status update text
| |
| ** '''ForegroundInactive''' used by the pager to draw non-active windows and frames, microblog for user names
| |
| ** '''ForegroundNormal''' used by microblog for status update entry area background
| |
| | |
| * '''[Colors:Complementary]'''
| |
| Same roles as Colors:Window, those are used in areas such as the logout screen, the screen locker etc, in order for them to have independent colors compared to normal plasmoids.
| |
| | |
| Note that some of these may end up folded back into Plasma::Theme properly at some point.
| |
| | |
| == Backgrounds format==
| |
| All background SVG's (except for wallpaper images) must have the following named elements, all of which will be painted at the ''native'' size (and can therefore be bitmaps), except for the center which will be scaled:
| |
| * '''topleft''': the top left corner
| |
| * '''topright''': the top right corner
| |
| * '''bottomleft''': the bottom left corner
| |
| * '''bottomright''': the bottom right corner
| |
| * '''top''': the top bar between the two top corners
| |
| * '''left''': the left bar between the two left corners
| |
| * '''right''': the right bar between the two right corners
| |
| * '''bottom''': the bottom bar between the two bottom corners
| |
| * '''center''': the center fill; will be scaled so should be an actual SVG element
| |
| | |
| Some Plasma components may use the above named elements with prefixes. For example the panel placed on the left side of the screen uses the "west" prefix ('''west-topleft''', '''west-topright''', etc.).
| |
| | |
| Additionally, the following elements can be used to control the rendering of the backgrounds:
| |
| | |
| * '''hint-stretch-borders''': if it exists, the borders will not be tiled but rather will be stretched to fit
| |
| * '''hint-tile-center''': if it exists, the center will not be scaled but rather will be tiled to fit. (Optional, from 4.1 and later)
| |
| * '''hint-no-border-padding''': If this element exists, padding will not be added for the borders, and content will therefore be able to use the entire area (inclusive borders).
| |
| * '''hint-apply-color-scheme''': If this element exists, the SVG will be colorized using the color scheme colors. Colorization is applied at 100%, and tapers off on either side, of an HSV color value/intensity of 127.
| |
| * '''current-color-scheme''': If a style element with this id exists it is replaced by a css-style with colors of the current colorscheme. See below for details.
| |
| * '''[prefix]-hint-[direction]-margin''': Use this optional hints if you want different margins than the borders size. The [prefix]- part is optional and identifies the prefix of the panel you want to specify the margins. [direction] can be either top, bottom, left or right and indicates the border you want to configure. For top and bottom margins the height of these hints are used, for left and right margins the width.
| |
| * '''[prefix]-hint-compose-over-border''': if this element is resent, the center element will be drawn with the same size as the total image, composed under the borders and shaped with the alpha mask frame, that has to be present in order to make work this hint(Optional).
| |
| | |
| Next there can be optionally another element called '''overlay''' (or '''[prefix]-overlay''' if to be appled to a frame with a different prefix) it will be rendered over the frame as a filigrane effects, with the rules given from the following mutually exclusive hints:
| |
| * '''hint-overlay-random-pos''' it will be put at a random position, this works just for applet backgrounds
| |
| * '''hint-overlay-tile''' tile the overlay
| |
| * '''hint-overlay-stretch''' the overlay will be stretched
| |
| * '''hint-overlay-pos-right''' align the overlay at right of the background rather than to the left
| |
| * '''hint-overlay-pos-bottom''' align the overlay at bottom of the background rather than to the top
| |
| | |
| ===Inkscape extension===
| |
| An Inkscape extension exists to automatically rename SVG elements with the above naming spec.
| |
| * download the two files at https://websvn.kde.org/trunk/playground/artwork/Oxygen/notmart/inkscapeextensions/
| |
| * copy them to $HOME/.config/inkscape/extensions
| |
| * restart inkscape
| |
| * select the 9 items of a frame (or the 4 items of an hint) and go to Extension->Plasma menu entry.
| |
| * put the optional prefix in the dialog
| |
| | |
| === Using system colors ===
| |
| It is possible to apply colors from the color scheme to a graphic. A very easy way to reach this is by adding an element with the id '''hint-apply-color-scheme''' to the SVG, In this case the rendered graphic gets converted to monochrome and colorized by the window background color.
| |
| | |
| [[File:EditingSvgIcon.png]]
| |
| | |
| A more flexible solution is available by using CSS-styling. For this to work the SVG must have a style-element with the id '''current-color-scheme'''. Before the graphic is rendered this element gets replaced by a style containing classes where the color attribute is set to the corresponding system color. Currently the following classes are defined:
| |
| * ColorScheme-Text
| |
| * ColorScheme-Background
| |
| * ColorScheme-Highlight
| |
| * ColorScheme-ViewText
| |
| * ColorScheme-ViewBackground
| |
| * ColorScheme-ViewHover
| |
| * ColorScheme-ViewFocus
| |
| * ColorScheme-ButtonText
| |
| * ColorScheme-ButtonBackground
| |
| * ColorScheme-ButtonHover
| |
| * ColorScheme-ButtonFocus
| |
| | |
| In order to apply a color from a class to an element, its fill or stroke attribute must be '''currentColor''' and of course the name of the wanted class has to be in the class-attribute. Special attention is needed on gradients, as neither the gradient-tags themselves nor the stop-tags accept classes. To still get the wanted result one can put a g-tag around them and apply the class to this.
| |
| | |
| In the Plasma-framework source repository, two useful tools are present:
| |
| * ''currentColorFix.sh'': fixes an error in the file format that inkscape often does that would break the coorect application of the stylesheet
| |
| * ''apply-stylesheet.sh'': looks in the SVG file for certain colors (by default from the Breeze palette) and replaces them with the corresponfing stylesheet class, automating a potential long and tedious job
| |
| | |
| == Current Theme Elements ==
| |
| | |
| Themes get installed to {{path|share/plasma/desktoptheme}}. Each theme is stored in an own sub-folder by the name of the theme with the following file structure (all files can be in either .svg or .svgz format):

| |
| *** There are also four backgrounds (north, south, east and west orientations) for the ruler widget itself in the "Backgrounds format", since the width of the widget is 100% the elements of left and right (or north and bottom if vertical) are not needed
| |
| ** '''/dragger.svg''': meant to be a generic drag handle (not currently used but available). It needs to contain the same elements as other backgrounds, see the section about backgrounds above. In addition it needs the following element:

| **'''/panel-background.svg''': the background image for panels.
| |
| *** If you want to create different background for panels located at the top, bottom, left or right, then also create sets of background elements with the following prefixes: ''north'', ''south'', ''west'' and ''east'' respectively. For example the center element of the left positioned panel's background should be named ''west-center''.
| |
| <!--*** When the panel is not 100% wide/tall the north, south etc. prefixes becomes ''north-mini'', ''south-mini'' etc. . Please note that if KRunner <menuchoice>Positioning</menuchoice> is set to <menuchoice>Top edge of screen</menuchoice> (which is default), then Plasma treats it as not 100% wide north panel.-->
| |
| *** All prefixes fallback to a no prefix version when not available
| |
| *** if a prefix called ''shadow'' is available, it will be used as a drop shadow for the panel when compositing is available.
| |
| ** '''/plot-background.svg''': a background for plotter (graph) widgets, such as the plots in ksysguard
| |
| ** '''/scrollbar.svg''' : the classical ''elevator'' scrollbar, must have the following elemens : ''arrow-up'', ''mouseover-arrow-up'', ''sunken-arrow-up'', same 3 elements for ''arrow-left'', ''arrow-right'' and ''arrow-bottom''. It can have an element called ''hint-scrollbar-size'' that says at what size the scrollbar should be rendered (width if vertical, height if horizontal). It must also have frames with the following prefixes:

| |
| *** ''horizontal-slider-line'': the background for horizontal sliders
| |
| *** ''horizontal-slider-handle'': the handle for horizontal sliders
| |
| *** ''horizontal-slider-focus'': background for the handle when it has input focus
| |
| *** ''horizontal-slider-hover'': background for the handle when it is under the mouse
| |
| **'''/tabbar.svg''': graphics elements for tabbars: contains 4 frames, each one for tabs in the possible orientations a tabbar can be relative to its contents, with the prefixes:
| |
| *** ''north''
| |
| *** ''west''
| |
| *** ''south''
| |
| *** ''east''
| |
| **'''/tasks.svg''': task item backgrounds for tasks. See the section on backgrounds above for information on the required elements in this file. The following element prefixes are required:
| |
| *** ''focus'': background of focused task item
| |
| *** ''hover'': background when the pointer hovers the task item. Focus and hover can have ticker borders that will be painted outside the task button, useful to make a glow effect.
| |
| *** ''attention'': background when tasks item is trying to get attention
| |
| *** ''normal'': background of normal, unfocused task item
| |
| *** ''minimized'': background for minimized tasks
| |
| *** All the frames can be prefixed with "north-", "west-", "south-" or "east-" if the taskbar should have a different look at the 4 sides of the screen
| |
| *** The svg should contain elements of all five prefixes, if a prefix is missing that element will be not be drawn.
| |
| *** ''panel-north'', ''panel-south'', ''panel-west'', ''panel-east'' : elements for the panel toolbox.
| |
| ** '''/tooltip.svg''': background for tooltips used for instance in the taskbar and with icons. See the section on backgrounds above for information on the required elements in this file.
| |
| ** '''/translucentbackground.svg''': a standard background image for plasmoids that for their nature are bigger and with not much text. In this case a translucent background looks better. It needs the same elements of background.svg in it. If this file is not present, the plasmoids that uses this will use background.svg instead.
| |
| ** '''/media-delegate.svg''': intended to be used as delegate for media types: it contains a single prefix: picture.
| |
| ** '''/viewitem.svg''': controls the background look of selections (results in KRunner, networks in network applet), it can have 4 elements of 9 parts each with prefix ''normal'', ''hover'', ''selected'', ''selected+hover''.
| |
| ** '''/toolbar.svg''': used in the ToolBar QML component, can be used in custom applications in a similar way, contains a single frame without prefix.

| =="Opaque" folder==
| |
| | |
| In the special subfolder {{path|opaque/}} the same hierarchy can be found again: when compositing is disabled files in this folder are preferred over the corresponding ones listed above. Only background for top level windows are appropriate to go in this folder.
| |
| | |
| Since top-level windows will be shaped according to the transparency of the SVG and window shapes don't support alpha-blending, if the SVG has rounded borders they should have a shape that don't require anti-aliasing, like the following example.

| [[Image:No_composite_plasma_svg.jpg]]
| |
| | |
| =="translucent" folder ==
| |
| | |
| In the special folder {{path|translucent/}} the same hierarchy is used as well: when the KWin ''Background Contrast'' effect is enabled the file under this folder will be used if found. As the opaque folder, only elements that will be rendered as window backgrounds should be present in this folder, so the dialogs folder, plus the panel and tooltip backgrounds. When is possible to blur the background of the window, the graphics can be more transparent, keeping the window text readable.
| |
| | |
| =="icons" folder==
| |
| | |
| In the folder {{path|icons/}}, SVG files that contain scalable icons for use with application status items (e.g. icons in the system tray) are contained.
| |
| | |
| Some of the common icons:
| |
| | |
| * audio.svg
| |
| * battery.svg
| |
| * computer.svg
| |
| * configure.svg
| |
| * device.svg
| |
| * input.svg
| |
| * media.svg
| |
| * network.svg
| |
| * notification.svg
| |
| * preferences.svg
| |
| * start.svg
| |
| * system.svg
| |
| | |
| The files are named the same as the icon theme name or their prefix, e.g. "audio.svg" or "audio-volume-high.svg". Multiple icons can be contained within a single file whose name must match the full icon name, e.g. "audio.svg" can contain elements named "audio-volume-muted", "audio-volume-low", "audio-volume-medium", and "audio-volume-high".
| |
| | |
| == Theming Application Icons in the System Tray ==
| |
| | |
| Applications that use a function called setIconByName can have their icon in the system tray themed. Applications can have more than one icon (for example Konversation flashes between two different icons to highlight when your username is mentioned and Kpackagekit changes it's icon depending on the status of it's upgrade / installs). Theming these icons requires firstly that an application has been coded to use setIconByName, and secondly that you call your SVG object by the same name (use Ctrl+Shift-O in Inkscape). Then you can just put your .svg in {{path|share/plasma/desktoptheme/[themename]/icons}}.
| |
| | |
| The following is an attempt to list known icon names that may be themed by this method. Please add any other known icon names and the object ID here to help other people making themes:
