Class Embed.ETextComponent

java.lang.Object

com.physpics.tools.ui.Embed

com.physpics.tools.ui.Embed.ETextComponent

All Implemented Interfaces:

java.awt.event.FocusListener, java.util.EventListener

Enclosing class:

Embed

public static class Embed.ETextComponent
extends Embed
implements java.awt.event.FocusListener

An Embed that manages a JTextField or a JTextArea. Typical usage:

 
         <img id="textareaA" aligny="0.84" embed="JTextArea" 
         src="images/textarea.png" width="100"  
         title="Click to type" note="Click here to type"/>

where width is in characters. In some cases the title is a popup hint; usually it seems to be ignored. The note value is the initial, grayed-out contents of the text. When the component gets the focus, the note is cleared.

Small bits of text can be directly embedded into HTML. SpeedsConverge has a document, bounceText.html, that displays a current speed with this html

<span id="bspeedspan">&zwnj;</span>&zwnj;&zwnj;70.

The Java code modifies the speed value like this

    Element bspeedspan = doc.getElement("bspeedspan");       
    int end = bspeedspan.getEndOffset();
    String ins = String.format("%3d", (int)(x-BALL_R));
    ins = ins.substring(0, 3); // stymie long drags
    ins = ins.replace(' ', '‌');    // ‌ zero-width         
    try {
        doc.replace(end+1, 3, ins, null);
    } catch (BadLocationException ex) {
        Message.impossible("setting B speed");
    }
