我在 Mozilla 3.6.x 中使用 GWT 2.0、GWT-Ext 1.5 和 Java 1.6。
我正在尝试根据此 link 实现 ThemeChanger 模块.但我无法实现它。谁能看看我的代码并告诉我我遗漏了什么或做错了什么？

入口点类:ThemeTest.java
@Override
public void onModuleLoad() {
FormPanel formPanel = new FormPanel();
formPanel.setTitle("Form");
TextField nameField = new TextField("Name");
TextField descField = new TextField("Desc");
formPanel.add(nameField);
formPanel.add(descField);
formPanel.add(new ThemeChanger());
RootPanel.get().add(formPanel);
}
ThemeChanger.java
public class ThemeChanger extends ComboBox {
public ThemeChanger() {
final Store store = new SimpleStore(new String[]{"theme", "label"}, new Object[][]{
new Object[]{"/public/resources/themes/green/css/xtheme-green.css", "Green"},
new Object[]{"", "Aero Glass"},
new Object[]{"/public/resources/themes/red/css/xtheme-red.css", "Red"},
new Object[]{"/public/resources/themes/gray/css/xtheme-gray.css", "Gray"},
});
store.load();
setFieldLabel("Select Theme");
setEditable(false);
setStore(store);
setDisplayField("label");
setForceSelection(true);
setTriggerAction(ComboBox.ALL);
setValue("Gray");
setFieldLabel("Switch theme");
addListener(new ComboBoxListenerAdapter() {
public void onSelect(ComboBox comboBox, Record record, int index) {
try {
String theme = record.getAsString("theme");
CSS.swapStyleSheet("theme", theme);
} catch (Exception e) {
e.printStackTrace();
}
}
});
setWidth(100);
}
}
最佳答案
检查主题的位置。
您可以下载 gxt-2.2.1.zip。
在您的计算机上将其解压缩。将有一个名为 resources 的目录，其中包含主题
您需要将其复制到您的项目位置。
我已经通过放置以下示例值检查了您的代码
new Object[]{"/test/resources/themes/slate/css/xtheme-slate.css", "Slate"},
new Object[]{"/test/resources/themes/access/css/xtheme-access.css", "Access"},
在 ThemeChanger 类中，主题在上面 .jar 中给出
成功了。
关于java - GWT-Ext 中的 ThemeChanger，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5603880/
