editor.bsh

用java 编写的源码开放的文本编辑器。有很多有用的特性

/**
	Open a workspace editor.
*/

bsh.help.editor = "usage: editor()";
import java.awt.*;

editor() {
	if ( bsh.system.desktop != void ) {
		return workspaceEditor( this.interpreter );
	}

	ta = new TextArea(15,40);
	frame = new Frame("Editor");
	frame.add(ta, "Center");

	p = new Panel();
	b = new Button("Eval");
	b.addActionListener(this);
	p.add(b);
	b = new Button("Clear");
	b.addActionListener(this);
	p.add(b);
	b = new Button("Close");
	b.addActionListener(this);
	p.add(b);

	frame.add(p, "South");
	frame.pack();
	frame.show();

	actionPerformed(e) {
		if ( e.getActionCommand().equals("Close") )
			frame.dispose();
		else if ( e.getActionCommand().equals("Clear") )
			ta.setText("");
		else
			this.interpreter.eval( ta.getText() );
	}

	print("Editor started...");
	return frame;
}
