MessageBox in GWT
提问by friedkiwi
How do I show a AJAX "Message Box" in GWT? I know I can use the Window.alert()function, but that's too ugly/annoying. Is there a built-in function for?
如何在 GWT 中显示 AJAX“消息框”？我知道我可以使用该Window.alert()功能，但这太丑陋/烦人了。有内置函数吗？
Thank you!
谢谢！

Here is simple implementation of custom alert widget (modify it to what you want):
这是自定义警报小部件的简单实现（将其修改为您想要的）：
public static DialogBox alertWidget(final String header, final String content) {
final DialogBox box = new DialogBox();
final VerticalPanel panel = new VerticalPanel();
box.setText(header);
panel.add(new Label(content));
final Button buttonClose = new Button("Close",new ClickHandler() {
@Override
public void onClick(final ClickEvent event) {
box.hide();
}
});
// few empty labels to make widget larger
final Label emptyLabel = new Label("");
emptyLabel.setSize("auto","25px");
panel.add(emptyLabel);
panel.add(emptyLabel);
buttonClose.setWidth("90px");
panel.add(buttonClose);
panel.setCellHorizontalAlignment(buttonClose, HasAlignment.ALIGN_RIGHT);
box.add(panel);
return box;
}
And use it like (note center() method at the end, it actually shows the widget):
并像使用它一样（注意最后的 center() 方法，它实际上显示了小部件）：
CustomWidgets.alertWidget("Adding account failed",
"System failed to add this account. Please chceck your settings properly.").center();

You can use DialogBox instead.
您可以改用 DialogBox。
