Quick Start

Add an upload control with a simple progress indicator to your app in 5 minutes.

Here's how to get started:

Download the GWT Uploader release jar file, and add it to your project's class path. E.g.:
lib/org.moxieapps.gwt.uploader-1.1.0.jar
Update your GWT module XML configuration file to import the GWT Highcharts module:
<inherits name="org.moxieapps.gwt.uploader.Uploader"/>
Within your GWT application, create a "Label" widget that will display the progress:
Label progress = new Label();
Create the "Uploader" widget, and set some configuration options using method chaining:
final Uploader uploader = new Uploader()
   .setUploadURL("/FileUploadServlet")
   .setButtonText("Upload Files")
   .setButtonWidth(150)
   .setButtonHeight(22);
Bind in handlers for the various events you're interested in:
uploader.setUploadProgressHandler(new UploadProgressHandler() {
   public boolean onUploadProgress(UploadProgressEvent evt) {
      progress.setText(
         NumberFormat.getPercentFormat().format(
            evt.getBytesComplete() / evt.getBytesTotal()
         )
      );
      return true;
   }
}).setFileDialogCompleteHandler(new FileDialogCompleteHandler() {
   public boolean onFileDialogComplete(FileDialogCompleteEvent evt) {
      progress.setText("Uploading...");
      uploader.startUpload();
      return true;
   }
});
Add the widgets to any GWT layout container:
RootPanel.get().add(uploader);
RootPanel.get().add(progress);
Run the application, click the button to select a file, and upload!
