How to align RichTextField to center?

Hey all,

 

Been picking at this for quite some time, using solutions found on many forums. Still unable to get it right. I have this simple about screen in my application, and i simply want all the lines of text to be centered on screen Horizontally, and Vertically too if that works. What am I doing wrong here?

 

 

package com.rim.samples.device.helloworlddemo;


import net.rim.device.api.system.Display;
import net.rim.device.api.ui.DrawStyle;
import net.rim.device.api.ui.Field;
import net.rim.device.api.ui.Manager;
import net.rim.device.api.ui.component.RichTextField;
import net.rim.device.api.ui.container.MainScreen;
import net.rim.device.api.ui.container.VerticalFieldManager;


public class AboutScreen extends MainScreen {

	/**
	 * 
	 */
	public AboutScreen() {
		super(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR);
		
		VerticalFieldManager vfm = new VerticalFieldManager(USE_ALL_WIDTH | FIELD_HCENTER){
			protected void sublayout(int maxWidth, int maxHeight) { 
				 
                super.sublayout(Display.getWidth(),Display.getHeight()); 
                setExtent(Display.getWidth(),Display.getHeight());

            } 

	    };
		vfm.add(new RichTextField("Lead Developer - Xxxx Xxxxxxx", Field.NON_FOCUSABLE | 			Field.FIELD_HCENTER));
		vfm.add(new RichTextField("For Support - xxxxxxxx@gmail.com", Field.NON_FOCUSABLE | 	Field.FIELD_HCENTER));
		vfm.add(new RichTextField("Follow us on Twitter - @xxxxxxxxxx", Field.NON_FOCUSABLE | 	Field.FIELD_HCENTER));
		vfm.add(new RichTextField("Version - 1.0.0", Field.NON_FOCUSABLE | Field.FIELD_HCENTER));
		add(vfm);
		
	}
	
	
}

 

 

Thanks,

Re: How to align RichTextField to center?

Could you try putting the RichTextField in a GridFieldManager?

 

so it would look something like

 

o=empty field

x=richtextfield

 

----- Grid Field Manager  ----

|o|o|o|

|o|x|o|

|o|o|o|

Re: How to align RichTextField to center?

I appreciate the response, but I dont feel that would solve my problem. All i need to to is align the text in the horizontal center of the screen. There must be some error in the properties i set in my code above or something.

Re: How to align RichTextField to center?

Try creating your RichTextField with TEXT_JUSTIFY_HCENTER (TEXT_ALIGN_HCENTER before OS 7.0) flag. FIELD_HCENTER tells the Manager where to put the field during layout. Those TEXT_ALIGN/TEXT_JUSTIFY flags tell the field how to display the text.

You might want to drop FIELD_HCENTER and use USE_ALL_WIDTH combined with that TEXT_JUSTIFY/TEXT_ALIGN flag - see what looks better.

Re: How to align RichTextField to center?

K so i ended up solving it easily using the following property in each RichTextField object-

 

RichTextField.TEXT_ALIGN_HCENTER

 

 

And that solved it all.

_rtf = new RichTextField("BlueTooth connection stop...", RichTextField.NON_FOCUSABLE | RichTextField.TEXT_JUSTIFY_HCENTER);

 

RichTextField.TEXT_ALIGN_HCENTER is Deprecated.

 

 

Cheers.
