| − | This article describes the themeing functionality of RWT, the RAP Widget Toolkit. | + | This page was obsolete and has been deleted. Please see the history if you need to access the content. |
| − | This themeing defines the default look and feel of the basic RWT controls like Shell, Button, Text etc.
| + | |
| − | It must not be mixed up with the themeing of the Eclipse workbench. Instead, it can be compared to the themeing functionality of a desktop system that allows the user to set custom colors for title bars, text background and the like.
| + | |
| − | | + | |
| − | == State of Development ==
| + | |
| − | | + | |
| − | The RWT themeing mechanism, as introduced with the M4 milestone, is still in an early state of development.
| + | |
| − | Some details are still likely to change, as our experience with this approach grows.
| + | |
| − | Your comments and suggestions are welcome.
| + | |
| − | | + | |
| − | Currently, the RWT themeing only allows to define colors.
| + | |
| − | Themeing of icons, fonts, borders, margins etc. will follow shortly.
| + | |
| − | | + | |
| − | == How to define a custom RWT Theme ==
| + | |
| − | | + | |
| − | === Create a custom theme file ===
| + | |
| − | | + | |
| − | RWT theme files are simple Java Property files.
| + | |
| − | A template named <code>theme-template.properties</code> can be found in the <code>src/</code> directory of the RWT plugin (<code>org.eclipse.rap.rwt</code>).
| + | |
| − | You only have to specify those properties that are relevant for your customization, as undefined properties will stay at their default value.
| + | |
| − | Note that some property names are likely to be changed in the future, other properties will emerge and a few properties will even be dropped.
| + | |
| − | Please refer to the template file shipped with your current version. | + | |
| − | See below for the syntax of the property values.
| + | |
| − | | + | |
| − | === Register the new theme with the extension point <code>org.eclipse.rap.swt.themes</code> ===
| + | |
| − | | + | |
| − | In the <code>plugin.xml</code> of your application project, add an extension like this:
| + | |
| − | | + | |
| − | <pre>
| + | |
| − | <extension
| + | |
| − | id="my.application.themes"
| + | |
| − | point="org.eclipse.rap.swt.themes">
| + | |
| − | <theme
| + | |
| − | id="my.application.aquablue"
| + | |
| − | name="Aqua Blue Test Theme"
| + | |
| − | file="aqua-blue.properties"
| + | |
| − | default="true"/>
| + | |
| − | </extension>
| + | |
| − | </pre>
| + | |
| − | | + | |
| − | === Activate the theme ===
| + | |
| − | | + | |
| − | The extension parameter <code>default</code> specifies whether the theme should be active by default.
| + | |
| − | Another method of activating a custom theme is by specifying the theme id with URL parameter <code>theme</code>.
| + | |
| − | Support for programmatic activation of custom themes is planned for future versions.
| + | |
| − | | + | |
| − | == Syntax for Property Values ==
| + | |
| − | | + | |
| − | Property values specified in a theme file must conform to the following syntactical rules:
| + | |
| − | | + | |
| − | === Colors ===
| + | |
| − | | + | |
| − | Colors can be specified in one of these ways:
| + | |
| − | | + | |
| − | * A color keyword.
| + | |
| − | Only the 16 basic [http://www.w3.org/TR/REC-html40/types.html#h-6.5 HTML 4.0 colors] (aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow) are supported.
| + | |
| − | The keywords are case-insensitive.
| + | |
| − | | + | |
| − | * A comma separated list of three decimal integer numbers in the range <code>0 .. 255</code> that denote the red, green, and blue portion of the color, respectively.
| + | |
| − | | + | |
| − | * A hexadecimal color notation in the format <code>#rgb</code> or <code>#rrggbb</code>, that is commonly used for HTML pages.
| + | |
| − | | + | |
| − | === Images ===
| + | |
| − | | + | |
| − | Custom images must be referred to using a '<tt>/</tt>'-separated path name that identifies the location of an image resource within the bundle.
| + | |
| − | | + | |
| − | === Fonts ===
| + | |
| − | | + | |
| − | | + | |
| − | === Borders ===
| + | |
| − | | + | |
| − | | + | |
| − | == SWT System Colors ==
| + | |
| − | | + | |
| − | The SWT system colors, as returned by <code>Display#getSystemColor()</code>, are also themeable.
| + | |
| − | The following list indicates which theme parameters manipulate these colors:
| + | |
| − | | + | |
| − | SWT.COLOR_WIDGET_DARK_SHADOW: widget.darkshadow
| + | |
| − | SWT.COLOR_WIDGET_NORMAL_SHADOW: widget.shadow
| + | |
| − | SWT.COLOR_WIDGET_LIGHT_SHADOW: widget.lightshadow
