WebRenderer Status bar

WebRenderer Status Bar functionality

WebRenderer has some convenience methods to allow the construction of a Swing status bar. Using the JProgressBar and JLabels it is easy to create a browser status bar based upon the WebRenderer Browser and Network events.

Using Events to bring your Status Bar to life

WebRenderer has some useful Network Events (com.webrenderer.events) to bring status bars and load progress bars to life.

IBrowserCanvas browser = BrowserFactory.spawnMozilla();

browser.addNetworkListener(new NetworkAdapter() {
   public void onProgressChange(NetworkEvent e) {
       //For getting text of the load progress
       System.out.println("Status Text: "+e.getStatusText());

       //Number of bytes downloaded
       System.out.println("Bytes downloaded: "+e.getCurrentProgress());
  }
});

Within the NetworkEvent class progress bar sizing and increment can be calculated by the following:

public void onProgressChange(NetworkEvent e) {
    //Total number of bytes to download for the page
    int maxNumberOfBytes = e.getMaximumProgress();

   //Status bar progress maximum size
   int maxsize = e.getMaximum();
}

Within the BrowserEvent class events such as onBeforeNavigate and onLinkChange are particularly useful for status bars.

browser.addBrowserListener(new BrowserAdapter() {
   public void onBeforeNavigate(BrowserEvent e) {
      System.out.println("Navigating to: " + e.getURL());
   }
   public void onLinkChange(BrowserEvent e) {
      System.out.println("Link: " + e.getLink()):
   }
});
