eclipe 4以上的插件就支持CSS主题切换的功能
plugin.xml 中扩展点org.eclipse.core.runtime.products、org.eclipse.e4.ui.css.swt.theme
<extension
id="product"
point="org.eclipse.core.runtime.products">
<product
application="org.eclipse.e4.ui.examples.css.rcp.application"
name="CSS Mail Example">
<property
name="aboutText"
value="CSS RCP Mail template">
</property>
<property
name="windowImages"
value="icons/sample2.gif">
</property>
<property
name="aboutImage"
value="icons/alt_about.gif">
</property>
<property
name="appName"
value="CSS Mail Example">
</property>
<!--一开始指定css-->
<span style="color:#ff0000;"><strong><!--<property
name="applicationCSS"
value="platform:/plugin/org.eclipse.e4.ui.examples.css.rcp/css/colorful.css">
</property>--></strong></span>
</product>
</extension>
<extension
point="org.eclipse.e4.ui.css.swt.theme">
<!--basestylesheeturi 指明绑定的css的位置-->
<theme
basestylesheeturi="<strong><span style="color:#ff0000;">css/default.css</span></strong>"
id="org.eclipse.e4.ui.examples.css.rcp"
label="RCP example theme">
</theme>
<theme
basestylesheeturi="<span style="color:#ff0000;"><strong>css/colorful.css</strong></span>"
id="org.eclipse.e4.ui.examples.css.colorful"
label="Colorful Example">
</theme>
</extension>
ThemeHelperl类用于生成主题引擎（用于不同css之间切换）
import org.eclipse.core.runtime.Platform;
import org.eclipse.e4.ui.css.swt.theme.IThemeEngine;
import org.eclipse.e4.ui.css.swt.theme.IThemeManager;
import org.eclipse.e4.ui.examples.css.rcp.Activator;
import org.eclipse.swt.widgets.Display;
import org.eclipse.ui.PlatformUI;
import org.osgi.framework.Bundle;
import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceReference;
/**
* 提供获得主题引擎
* @author Administrator
*
*/
@SuppressWarnings("restriction")
public class ThemeHelper {
private static IThemeEngine engine = null;
private static Bundle bundle = Platform.getBundle(Activator.PLUGIN_ID);
public static IThemeEngine getEngine() {
if (engine == null) {
engine = getThemeEngine();
}
return engine;
}
private static IThemeEngine getThemeEngine() {
BundleContext context = bundle.getBundleContext();
ServiceReference ref = context.getServiceReference(IThemeManager.class.getName());
IThemeManager manager = (IThemeManager) context.getService(ref);
return manager.getEngineForDisplay(PlatformUI.getWorkbench()
.getActiveWorkbenchWindow() == null ? Display.getCurrent()
: PlatformUI.getWorkbench().getActiveWorkbenchWindow()
.getShell().getDisplay());
}
}用于切换主题的操作
import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.e4.ui.examples.css.rcp.theme.ThemeHelper;
/**
* 切换主题的实现类
* @author Administrator
*
*/
public class SwitchTheme extends AbstractHandler {
private boolean reset = false;
private final static String USER_CSS_DEFAULT = "org.eclipse.e4.ui.examples.css.rcp";//plugin.xml中的主题ID
private final static String USER_CSS_COLORFUL = "org.eclipse.e4.ui.examples.css.colorful";
public Object execute(ExecutionEvent event) throws ExecutionException {
String themeId = "";
if (reset) { // toggle functionality of the menu item
themeId = USER_CSS_DEFAULT;
} else {
themeId = USER_CSS_COLORFUL;
}
reset = !reset;
ThemeHelper.getEngine().setTheme(themeId, true);
return null;
}
}Plugin.xml中设置的command
<extension
point="org.eclipse.ui.commands"><!--用户添加菜单项到相应的位置-->
<command
defaultHandler="org.eclipse.e4.ui.examples.css.rcp.handler.SwitchTheme"
id="org.eclipse.e4.ui.examples.css.rcp.switchtheme"
name="Switch Theme"><!--切换主题的操作-->
</command>
</extension><extension
point="org.eclipse.ui.menus">
<menuContribution
allPopups="false"
locationURI="menu:org.eclipse.ui.main.menu">
<menu
label="Styling">
<command
commandId="org.eclipse.e4.ui.examples.css.rcp.switchtheme"
label="Switch Styling"
style="push">
</command>
</menu>
</menuContribution>
</extension>把command绑定到菜单栏中
<extension
point="org.eclipse.ui.menus">
<menuContribution
allPopups="false"
locationURI="menu:org.eclipse.ui.main.menu">
<menu
label="Styling">
<command
commandId="org.eclipse.e4.ui.examples.css.rcp.switchtheme"
label="Switch Styling"
style="push">
</command>
</menu>
</menuContribution>
</extension>ApplicationWorkbenchAdvisor 中可以用代码一开始指定某个主题
public void initialize(IWorkbenchConfigurer configurer) {
super.initialize(configurer);
/**设置系统的默认主题风格*/
Bundle b = FrameworkUtil.getBundle(getClass());
BundleContext context = b.getBundleContext();
ServiceReference serviceRef = context
.getServiceReference(IThemeManager.class.getName());
IThemeManager themeManager = (IThemeManager) context
.getService(serviceRef);
final IThemeEngine engine = themeManager.getEngineForDisplay(Display
.getCurrent());
engine.setTheme("org.eclipse.e4.ui.examples.css.rcp", true);
if (serviceRef != null) {
serviceRef = null;
}
if (themeManager != null) {
themeManager = null;
}
