问题
I need to align a CheckboxField to the right of a fixed text (on Blackberry) like the "manage connections" dialog. The code is:
final HorizontalFieldManager hfm = new HorizontalFieldManager(USE_ALL_WIDTH);
hfm.add(new LabelField("Test me please", LabelField.ELLIPSIS | FIELD_LEFT | FIELD_VCENTER | USE_ALL_WIDTH));
cbx = new CheckboxField(null, false, FIELD_RIGHT | CheckboxField.NO_USE_ALL_WIDTH);
hfm.add(cbx);
I tried various combinations of "USE_ALL_WIDTH", "NO_USE_ALL_WIDTH" and similar flags, but I still can't get what I want: text all the way to the left, and check box all the way to the right. If the label is set to USE_ALL_WIDTH, the checkbox disappears, and if it's not set, the checkbox is displayed near the text (not on the right side of the hfm).

Use following code,this will solve your problem.
HorizontalFieldManager hfm = new HorizontalFieldManager(Field.USE_ALL_HEIGHT);
LabelField lblShow = new LabelField("Test me please ", Field.FIELD_LEFT);
CheckboxField cbShow = new CheckboxField("", false, CheckboxField.FIELD_RIGHT );
VerticalFieldManager vfmLeft = new VerticalFieldManager();
VerticalFieldManager vfmRight = new VerticalFieldManager(Field.USE_ALL_WIDTH);
vfmLeft.add(lblShow);
vfmRight.add(cbShow);
hfm.add(vfmLeft);
hfm.add(vfmRight);
add(hfm);

Use This style bit to align checkbox to right.
private static final long checkBoxStyle = 134217728;
add(new CheckboxField("test " , false, checkBoxStyle | USE_ALL_WIDTH));
