# Class TextArea

java.lang.Object
com.codename1.ui.Component
com.codename1.ui.TextArea

All Implemented Interfaces:
  `Animation, Editable, ActionSource, StyleListener, TextHolder`

Direct Known Subclasses:
  `TextField`

public class TextArea extends Component implements ActionSource, TextHolder

An optionally multi-line editable region that can display text and allow a user to edit it. By default the text area will grow based on its content.

`TextArea` is useful both for text input and for displaying multi-line data, it is used internally by components such as `com.codename1.components.SpanLabel` & `com.codename1.components.SpanButton`.

`TextArea` & `com.codename1.ui.TextField` are very similar, we discuss the main differences between the two `here`. In fact they are so similar that our sample code below was written for `com.codename1.ui.TextField` but should be interchangeable with `TextArea`.

    TableLayout tl;
    int spanButton = 2;
    if(Display.getInstance().isTablet()) {
        tl = new TableLayout(7, 2);
    } else {
        tl = new TableLayout(14, 1);
        spanButton = 1;
    }
    tl.setGrowHorizontally(true);
    hi.setLayout(tl);

    TextField firstName = new TextField("", "First Name", 20, TextArea.ANY);
    TextField surname = new TextField("", "Surname", 20, TextArea.ANY);
    TextField email = new TextField("", "E-Mail", 20, TextArea.EMAILADDR);
    TextField url = new TextField("", "URL", 20, TextArea.URL);
    TextField phone = new TextField("", "Phone", 20, TextArea.PHONENUMBER);

    TextField num1 = new TextField("", "1234", 4, TextArea.NUMERIC);
    TextField num2 = new TextField("", "1234", 4, TextArea.NUMERIC);
    TextField num3 = new TextField("", "1234", 4, TextArea.NUMERIC);
    TextField num4 = new TextField("", "1234", 4, TextArea.NUMERIC);

    Button submit = new Button("Submit");
    TableLayout.Constraint cn = tl.createConstraint();
    cn.setHorizontalSpan(spanButton);
    cn.setHorizontalAlign(Component.RIGHT);
    hi.add("First Name").add(firstName).
            add("Surname").add(surname).
            add("E-Mail").add(email).
            add("URL").add(url).
            add("Phone").add(phone).
            add("Credit Card").
                    add(GridLayout.encloseIn(4, num1, num2, num3, num4)).
            add(cn, submit);

  - ### getPreferredTabIndex

    public int getPreferredTabIndex()
    Description copied from class: `Component`

    Gets the preferred tab index of this component. Tab indices are used to specify the traversal order when tabbing from component to component in a form.

    Tab index meanings work similar to the HTML tabIndex attribute. A tab Index of -1 (the default value) results in the field not being traversable using the keyboard (or using the next/prev buttons in devices' virtual keyboards). A tab index of 0 results in the component's traversal order being dictated by the natural traversal order of the form.

    Use `Form#getTabIterator(com.codename1.ui.Component)` to obtain the complete traversal order for all components in the form.

    Best practice is to only explicitly set preferred tabIndex values of 0 if you want the component to be traversable, or -1 if you don't want the component to be traversable. Explicitly setting a positive preferred tab index may result in unexpected results.

    How the Preferred Tab Index is Used

    When the user tries to "tab" to the next field (or presses the "Next" button on the virtual keyboard), this triggers a call to `Form#getTabIterator(com.codename1.ui.Component)`, crawls the component hierarchy and returns a `java.util.ListIterator` of all of the traversable fields in the form in the order they should be traversed. This order is determined by the layout managers on the form. The core layout managers define sensible traversal orders by default. If you have a custom layout manager, you can override its traversal order by implementing the `com.codename1.ui.layouts.Layout#overridesTabIndices(com.codename1.ui.Container)` and `com.codename1.ui.layouts.Layout#getChildrenInTraversalOrder(com.codename1.ui.Container)` methods.

    ###### Returns

    the tabbing index

      `getPreferredTabIndex` in class `Component`
