com.ibm.lpex.samples
Class Lpex

java.lang.Object
  com.ibm.lpex.samples.Lpex

public final class Lpex

extends Object

Sample stand-alone editor built on the LPEX edit widget.

Here is the Lpex source code.

To run this sample from the command line:

   java [java options] com.ibm.lpex.samples.Lpex [filename]
        [-encoding encoding] [-extension {extension | none}] 

A possible Windows batch program is:

   @start /b java com.ibm.lpex.samples.Lpex %1 %2 %3 %4 %5 %6 %7 %8 %9 

To disable the JIT compiler, run it with this option:

   -Djava.compiler= 

You can run Lpex in a particular locale. For example, in order to run it in Simplified Chinese (zh_CN), use these two options:

   -Duser.language=zh -Duser.region=CN 

Commands and actions defined in here:

• exit command - close all Lpex views of the document
• Lpex command - open a new Lpex window
• openNewView command - open an additional view on the document
• quit command - unconditionally quit the Lpex window
• test command - placeholder for testing new commands
• viewProfile command - view the LPEX defaults profile
• viewLog command - view the LPEX editor log
• close action (F3) - close the Lpex window
• nextView action (Ctrl+Alt+->) - go to the next view of this document
• openNewView action (Ctrl+O) - open an additional view on the document
• prevView action (Ctrl+Alt+<-) - go to the previous view of this document
• test action - placeholder for testing new actions.

Example user-defined editor action to open an additional document view with Lpex:

 
 lpexView.defineAction("openNewView", new LpexAction() {
  public void doAction(LpexView view)
  {
   Display display = getDisplay();
   display.asyncExec(new Runnable() {
    public void run() {
     try
      {
       Class cl = Class.forName("com.ibm.lpex.samples.Lpex");
       Constructor lpexConstructor = cl.getConstructor(new Class[]
        { LpexView.class, com.ibm.lpex.samples.Lpex.Delegate.class,
          Rectangle.class, java.lang.Boolean.TYPE });
       lpexConstructor.newInstance(new Object[]
        { getView(), getDelegate(), new Rectangle(10, 10, 648, 711), 
          new java.lang.Boolean(false) });
      }
     catch (Exception e) {}
     }});
  }
  public boolean available(LpexView view)
  { return true; }
 });
