SWT/XML is a lightweight XML markup language for describing Eclipse SWT / RCP user interfaces. It includes an Eclipse Web Tools based IDE editor plug-in.

Eclipse Update Site: http://www.swtxml.com/updates/

Requirements: Eclipse 3.4 for RCP/Plug-in Developers or newer, Java 1.5 or newer

Features

• Very readable and compact XML grammar for describing SWT user interfaces. Example:

<?xml version="1.0" encoding="utf-8"?>
<Composite xmlns="http://www.swtxml.com/swt" layout="layout:fill;">
    
    <TabFolder>
        <TabItem text="RowLayout">
            <Composite layout="layout:row; type:vertical; spacing:5;">
                <Button text="Button" style="CHECK"/>
                <Label text="Test:" layoutData="widthHint:120;"/>
                <Combo style="READ_ONLY" toolTipText="whatever"/>
            </Composite>
        </TabItem>
    </TabFolder>
	
</Composite>

• Easy to learn and to use. SWT/XML provides a 1:1 mapping from SWT widget classes to XML tags. If you know SWT, you just need to learn few general rules.

• I18N support using label properties and resource bundles (same as for plugin.xml files):

<Button text="%property"/>

• Eclipse IDE plug-in with Content Assist and Preview:

• Strict markup validation with meaningful exception messages.

• Easy integration in your application, the runtime library of SWT/XML is very small (~ 170KB) and has almost no external dependencies (except for Eclipse RCP plug-ins)
