Hi

i'm trying to make one of my own custom Edit field.
I'm referring to the code in the thread "Border & Basic Editfield"

where the Wikipedia interface is provided and a custom edit field, but when i try to make it bigger, by changing it width and height in the layout like:

public void layout(int width,int height)
{
setExtend(120,100);
}

it gives me the Exception,

If i remove the layout , it works fine, but i want to make it bigger in height mainly, and overrider couple of things like making it multi-line.

Here's the modified code of Custom Edit field, posted here earlier:

import net.rim.device.api.ui.*;
import net.rim.device.api.ui.component.*;

public class TextEntryWidget extends EditField {
int labelColor = Color.BLACK;
Font labelFont = getFont();
int textColor = Color.BLACK;
int borderColor = Color.BLACK;
int horizontalsize = 150;
int maxChars = 30;
String text = "";
String fulltext = "";
int leftMargin = 0;
public TextEntryWidget() {
super();
}
public TextEntryWidget(long style) {
super(style);
}
public TextEntryWidget(String label, String initialValue) {
super(label, initialValue);
}
public TextEntryWidget(String label, String initialValue, int maxNumChars, long style) {
super(label, initialValue, maxNumChars, style);
maxChars = maxNumChars;
}

public void paint(Graphics graphics) {
String txt = this.getText();
graphics.setColor(textColor);
graphics.setFont(getFont());
graphics.drawText(txt, 51, 0);
graphics.setColor(borderColor);
graphics.drawRoundRect(49, 0, 150, 20, 5, 5);
}
public void drawFocus(Graphics g, boolean on) {
//
}

}

now , if i add the following to the above code, it gives me ArrayIndexOutofBoundException

public void layout(int width,int height)
{
setExtent(100,100);
}

Just to update on the findings, as it might help someone else too.

If i make a custom field by extending the Field class, then no matter what extent i use and the layout method , it works fine.

But i would very much like to use the functionalities of the EditField (code reusability) rather than write whole thing again.

Hi rock_win,

I didn't face any problem with this code. I've used JDE 4.2.1 to build and runs on 8700g simulator.

But I do experience the same error when try to build using JDE 4.0 and runs on 7210 simulator.

This may be the cause of PLATFORM or amount of available space . I'll get back to you next time with expected point. But before that can you please send me your Environment details?

Hi Arif

thats a nice observation for platforms.

I'm working on 7290 simulator, platform ver 4.0.2
