Interface FileDialogStartHandler

public interface FileDialogStartHandler

An interface that can be used as a callback handler when file dialog start events are fired by the Uploader component. General usage is as follows:

 uploader.setFileDialogStartHandler(new FileDialogStartHandler() {
    public boolean onFileDialogStart(FileDialogStartEvent event) {
       Window.alert("Starting the file selection dialog...");
       return true;
    }
 });
 

Note that the 'fileDialogStart' is fired after selectFile for selectFiles is called. This event is fired immediately before the File Selection Dialog window is displayed. However, the event may not execute until after the Dialog window is closed.

See the documentation on the FileDialogStartEvent class for more details on the data available when a file dialog start event occurs.
