TE Edit Control for Java

The Tej class extends the the Panel class. Here are the steps to add a Tej class object to your application Frame window.

(Please refer to the ASP.NET Interface for a description of the steps needed to insert a Tejw Applet object into your ASP.NET application).

To start, extract the tej32.jar files into one of the folders in the class path:

jar -xfv tej32.jar

This would create a new subdirectory called tej where the Tej class files are extracted. 'tej' is also the name of the package for this product. The 'import' statement should be used on the top of your application to access the editor classes.

Now follow these steps to insert a Tej control to your application.

   import tej.*;
   public class dmo_te extends Frame implements WindowListener 
   {
   Tej tej=null;                                                                         
   JMenuBar MainMenu=null;
   public dmo_te()
   {
     frame=this;
     addWindowListener(this);
     // Set the frame dimensions
     setLocation(x,y);
     setSize(width,height);
     setTitle("Unknown");
     // Create tej control
     // Only design-time methods should be used here since the Tej control is not yet created.
     // Such code should is added in the OnCreate function below
     tej = new Tej();
     tej.addTejListener(tej_listener);
     tej.setWordWrap(true);       // Word wrap
     tej.setPageMode(true);       // page mode
     tej.setPrintViewMode(true);  // print-view mode
     tej.setFittedView(true);     // fitted view mode
     tej.setShowRuler(true);      // show the ruler
     tej.setShowVertRuler(true);     // show vertical ruler
     tej.setShowStatusBar(true);  // show the status bar
     tej.setShowToolBar(true);    // show the toolbar
     tej.setVertScrollBar(true);  // show vertical toolbar
     tej.setHorzScrollBar(true);  // show the horizontal scroll bar
     tej.setBorderMargin(true);   // create the border margin
     tej.setReadOnlyMode(false);  // read only
     // add following to show the menu
     MainMenu=tej.TerBuildMenu();
     MainMenu.setBorder(BorderFactory.createLineBorder(Color.black));
     add(MainMenu,BorderLayout.NORTH);
     // add the Tej control, the control is actually constructed in the WindowActivated event
     add(tej);   // add tej control to your Frame
   /*********************************************************************
