hello all...

i try to crreate a custom editfield 

import net.rim.device.api.system.Bitmap;
import net.rim.device.api.ui.Color;
import net.rim.device.api.ui.DrawStyle;
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;
import net.rim.device.api.ui.Ui;
import net.rim.device.api.ui.XYEdges;
import net.rim.device.api.ui.component.Dialog;
import net.rim.device.api.ui.component.EditField;
import net.rim.device.api.ui.decor.Border;
import net.rim.device.api.ui.decor.BorderFactory;

public class BorderEditField extends EditField {
	
	private Border unFocusBorder = BorderFactory.createBitmapBorder( new XYEdges( 12, 12, 12, 12), Bitmap.getBitmapResource("border.png"));
	
	BorderEditField() {
		super();
	}
	
	BorderEditField(long style) {
		super(style);
	}
	
	BorderEditField(String label, String initialValue) {
        super(label, initialValue);
    }
 
    BorderEditField(String label, String initialValue, int maxNumChars, long style) {
        super(label, initialValue, maxNumChars, style | Field.USE_ALL_WIDTH);
        super.setFont(getTextFont());        
        setBorder(unFocusBorder);
    }    
    
    public void paint(Graphics g) {    	
        g.setColor(Color.BLACK);       
        g.drawText(super.getText(), 0, 0, DrawStyle.HCENTER + DrawStyle.ELLIPSIS + DrawStyle.TRUNCATE_BEGINNING, getWidth() - 12);        
    }
    
    protected void layout(int width, int height) {
        super.layout(width, height);
    }
    
    private Font getTextFont() {
    	FontFamily alphaSerifFamily = null;
    	try {
			alphaSerifFamily = FontFamily.forName("bbalpha serif");			
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			Dialog.alert(e.getMessage());
		}
    	return alphaSerifFamily.getFont(Font.PLAIN, 18, Ui.UNITS_pt);
    }    

}

 when i enter a char that more the field could display it would create like a new line but the text is still on the 1st line

the 2nd line was empty...

how to make the custom editfield not showing the 2nd line? since the 2nd line was an empty text

the text was only on 1st line

[simon_hain]

why don't you use setBorder on a standard editfield?

[anditsung]

yes i could but i want to paint it as i want, thats why i create another class for it

the problem is like the picture

[simon_hain]

if you want to have custom painting you should override field, not editfield.
editfield is a VERY complex class with loads of processing, you cannot modify it heavily (overriding paint is quite some) and expect it to work.

Agree with Simon.

In your case change this:

    public void paint(Graphics g) {   
        g.setColor(Color.BLACK);      
        g.drawText(super.getText(), 0, 0, DrawStyle.HCENTER + DrawStyle.ELLIPSIS + DrawStyle.TRUNCATE_BEGINNING, getWidth() - 12);       
    }

to this:

    public void paint(Graphics g) {   
        g.setColor(Color.BLACK);       
        super.paint(g)

    }

and see if your problem is resolved.

so its not possible to make 1 line ? have to create a new class for it?

@peter
using super.paint(g) is still display as normal edit field

[anditsung · Accepted solution]

well i found a way to make it work

protected void layout(int width, int height) {
    	super.setExtent(width, height);
    	setExtent( isStyle( USE_ALL_WIDTH ) ? width : getPreferredWidth(), getPreferredHeight() );    	
    }
    
    public void updateScreen() {
    	invalidate();
    }

 im adding this to the bordereditfield

but have to invalidate everytime i enter a text.
