Edit FIeld - center and with numeric keypad



      I want a text field, which is using for enter numbers. I want to make it center. And want to allow it with numeric keypad.


It was working fine with BB OS 5 and when using BB OS 6 / 7 / 7.1, I was unable to show numeric keypad.


Follwing is the code:


txtEventNumber = new RichTextField(RichTextField.TEXT_ALIGN_HCENTER) {
public void paint(Graphics graphics) {
int oldColor = Color.GRAY;

Font font = this.getFont().derive(Font.EMBOSSED_EFFECT, 20);

graphics.drawRoundRect(0, 0, getWidth(), getHeight(), 10, 10);


public int getPreferredHeight() {
return super.getPreferredHeight() + ADD_MARGIN;

protected void onFocus(int direction) {
if (Touchscreen.isSupported() && getScreen().getVirtualKeyboard() != null)
// Show keyboard

protected void onUnfocus() {
if (Touchscreen.isSupported() && getScreen().getVirtualKeyboard() != null)
// Hide keyboard
// can enter only numeric digits
if (Touchscreen.isSupported())
// show numeric keypad

txtEventNumber.setMargin(10, 10, 0, 10);

Re: Edit FIeld - center and with numeric keypad

why do all the effort to show and hide the keyboard? just use a NumericTextFilter according to your needs on the text field. The device will automatically handle what keyboard to show and what not to.

I've got 99 problems and eclipse is all of them

Re: Edit FIeld - center and with numeric keypad

Hi newton53,

                         NumericTextFilter is not useful to me.


I am using it in OS 6 and OS 7.1.

When I am using EditField, I was able to get numeric keypad(using TextFilter) but was unable to set the text in CENTER horizontally.


And When using RichTextField, I was able to set text in CENTER horizontally(using RichTextField.TEXT_ALIGN_HCENTER). But was unable to show numeric keypad.


Please provide me any code to use edit field, which can I set horizontally CENTER and can show Numeric keypad for OS 6(and later).

It is most needed.
