A panel that lays all of its widgets out in a single horizontal column.
Here is an example of how to use this widget:
function doGet() {
var app = UiApp.createApplication();
var panel = app.createHorizontalPanel();
panel.add(app.createButton("button 1"));
panel.add(app.createButton("button 2"));
app.add(panel);
return app;
}
Internally, UiApp widgets are built on top of the Google Web Toolkit, and it can sometimes be helpful to look at the GWT documentation directly. You can find the HorizontalPanel documentation here.
