I saw a post on this somewhere, and I'm probably going to kick myself, but for the life of me I can't find the post, or remember how to do this.

Basically, I want to make a LabelField which contains an email or web URL, clickable.  Anyone point me to something?

you could override some methods of a label field but i prefer to use this: href field

import net.rim.device.api.ui.Field;
import net.rim.device.api.ui.Font;
import net.rim.device.api.ui.FontFamily;
import net.rim.device.api.ui.Graphics;

public class HrefField extends Field {

private String content;
private Font fieldFont;
private int fieldWidth;
private int fieldHeight;
private boolean active = false;
private int backgroundColour = 0xffffff;
private int textColour = 0x333333;
private int maskColour = 0xBBBBBB;

public HrefField(String content) {
super(Field.FOCUSABLE);
this.content = content;
fieldFont = defaultFont();
fieldWidth = fieldFont.getAdvance(content)+2;
fieldHeight = fieldFont.getHeight() + 3;
}

public void setColours(int backgroundColour, int textColour, int maskColour) {
this.backgroundColour = backgroundColour;
this.textColour = textColour;
this.maskColour = maskColour;
invalidate();
}

public void setBackgroundColour(int backgroundColour){
this.backgroundColour = backgroundColour;
invalidate();
}

public void setTextColour(int textColour){
this.textColour = textColour;
invalidate();
}

public void setMaskColour(int maskColour){
this.maskColour = maskColour;
invalidate();
}

public void setFont(Font fieldFont){
this.fieldFont = fieldFont;
}

public int getPreferredWidth() {
return fieldWidth;
}

public int getPreferredHeight() {
return fieldHeight;
}

protected void layout(int arg0, int arg1) {
setExtent(getPreferredWidth(), getPreferredHeight());
}

protected void paint(Graphics graphics) {

if (active) {
graphics.setColor(maskColour);
graphics.fillRect(0, 0, fieldWidth, fieldHeight);
} else {
graphics.setColor(backgroundColour);
graphics.fillRect(0, 0, fieldWidth, fieldHeight);
}

graphics.setColor(textColour);
graphics.setFont(fieldFont);
graphics.drawText(content, 1, 1);
graphics.drawLine(1, fieldHeight-2, fieldWidth-2, fieldHeight-2);
}

protected boolean navigationClick(int status, int time) {
fieldChangeNotify(1);
return true;
}

protected void onFocus(int direction) {
active = true;
invalidate();
}

protected void onUnfocus() {
active = false;
invalidate();
}

public static Font defaultFont() {
try {
FontFamily theFam = FontFamily.forName("SYSTEM");
return theFam.getFont(net.rim.device.api.ui.Font.PLAIN, 14);
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
}
return null;
}
}

Just for completeness, can I add the following?

LabelField _testLink = new LabelField("Test", Field.FOCUSABLE | Field.USE_ALL_WIDTH) {
    protected boolean navigationClick(int status, int time) {
        System.out.println("Linked");
        return true;
    }
};

You can also use an ActiveAutoTextEditField and adjust the READONLY and FOCUSABLE properties as desired.

Actually, when I say "clickable", what I mean is not just that it is focable, but that when you click an email, it will invoke a compose of an email message, or when you click a URL, it will invoke the browser.

[MSohm]

In that case you could use an ActiveAutoTextEditField (as Tariq mentioned bove).

I recommend that you do not add new questions to existing Threads, especially if the Tread has been solved.  Start a new Thread, which I see you have done here:

[manarS]

Tariq, i did what you recommended..

but it doesn't work . it displays just like any label field, no different.

hyperlink=new ActiveAutoTextEditField("mnr.mars.87@gmail.com", " ", 30, Field.FOCUSABLE | Field.READONLY);
