Class AlignedLabelsContainer

  • public class AlignedLabelsContainer
extends Container
    AlignedLabelsContainer is a Container used to align all controls to the maximum width of a set of labels. You can define the label alignment. The controls that you add to this container are placed at the right of the labels. Here's a sample of how to use it: 
     String[] labels =
 {
    "Name",
    "Born date",
    "Telephone",
    "Address",
    "City",
    "Country",
    "",
 };
 AlignedLabelsContainer c = new AlignedLabelsContainer(labels);
 c.setBorderStyle(BORDER_LOWERED);
 c.labelAlign = RIGHT;
 c.foreColors = new int[]{Color.RED,Color.BLACK,Color.BLACK,Color.BLACK,Color.BLACK,Color.BLACK,Color.BLACK,};
 c.setInsets(2,2,2,2);
 c.setFont(font.asBold()); // labels are bold
 c.childrenFont = font;    // but controls are normal
 add(c,LEFT+2,TOP+2,FILL-2,PREFERRED+4);
 for (int i =0; i < labels.length-2; i++)
    c.add(new Edit(),LEFT+2,AFTER+(i==0?2:0));
 c.add(new ComboBox(new String[]{"Brazil","France"}),LEFT+2,AFTER);
 c.add(new Button("Insert data"),RIGHT,SAME);
 c.add(new Button("Clear data"),RIGHT,AFTER,SAME,PREFERRED);
