# Class Component

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

All Implemented Interfaces:
  `Animation, Editable, StyleListener`

Direct Known Subclasses:
  `ChartComponent, CommonProgressAnimations.ProgressAnimation, Container, ImageViewer, InfiniteProgress, Label, List, PeerComponent, Switch, TextArea`

public class Component extends Object implements Animation, StyleListener, Editable

The component class is the basis of all UI widgets in Codename One, to arrange multiple components together we use the Container class which itself "IS A" Component subclass. The Container is a Component that contains Components effectively allowing us to nest Containers infinitely to build any type of visual hierarchy we want by nesting Containers.

Style Change Events

Styles fire a change event for each style change that occurs. `Component` listens to all changes events of its styles, and adjusts some of its properties accordingly. Currently (as of 6.0) each style change will trigger a `Container#revalidate()` call on the Style's Component's parent container, which is expensive. You can disable this `Container#revalidate()` call by calling `"false")`. This will likely be the default behavior in a future version, so we recommend you disable this explicitly for both performance reasons, and to avoid regressions when the default is changed.

    - `g`: the graphics object

  - ### paintShadows

    public void paintShadows(Graphics g, int relativeX, int relativeY)

    Paints the drop-shadow projections for this component based on its elevation value.

    This is called by the ancestor "surface" container of the component, after it paints its background, but before painting its children. If the `Style#getElevation()` of the component is 0, then no shadow will be painted. Similarly, if the component has no ancestor container which is a surface (i.e. `Container#isSurface()` is true, the shadow will not be painted.

    NOTE: It is also possible that the shadow will not be visible if other opaque components are painted in front of the ancestor surface container. This is one of the limitations of this approach for simulating elevation.

    Note: Not all platforms support drawing shadows. Use `CodenameOneImplementation#isDrawShadowSupported()` to check for support at runtime.

    ###### Parameters

    - `g`: The graphics context onto which the shadow should be painted.

    ###### Returns

    The tab index of the component.

    ###### Deprecated

    This method is used internally when querying the traversal order of the form. Use `#getPreferredTabIndex()` to get the preferred tab index.

    ###### See also

    - #getPreferredTabIndex()

    - #setTabIndex(int)

    - #setPreferredTabIndex(int)

    - Form#getTabIterator(com.codename1.ui.Component)

    - Container#updateTabIndices(int)

  - ### setTabIndex

    public void setTabIndex(int index)

    Sets the tab index of the component. This method is for internal use only. To set the preferred tab index, use `#setPreferredTabIndex(int)`

    ###### Parameters

    - `index`: The tab index.

    ###### Deprecated

    This method is called internally by the layout manager each time the traversal order of the form is queried. Use `#setPreferredTabIndex(int)` instead.

    ###### See also

    - #getPreferredTabIndex()

    - #setPreferredTabIndex(int)

    - #getTabIndex()

    - Form#getTabIterator(com.codename1.ui.Component)

  - ### getPreferredTabIndex

    public int getPreferredTabIndex()

    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

  - ### setPreferredTabIndex

    public void setPreferredTabIndex(int index)

  - ### initComponent

    protected void initComponent()
    Allows subclasses to bind functionality that relies on fully initialized and "ready for action" component state

  - ### isInitialized

    protected boolean isInitialized()

    Indicates if the component is in the initialized state, a component is initialized when its initComponent() method was invoked. The initMethod is invoked before showing the component to the user.

    ###### Returns

    true if the component is in the initialized state

  - ### setInitialized

    protected void setInitialized(boolean initialized)

    Indicates if the component is in the initialized state, a component is initialized when its initComponent() method was invoked. The initMethod is invoked before showing the component to the user.

    - `initialized`: Indicates if the component is in the initialized state

  - ### styleChanged

    public void styleChanged(String propertyName, Style source)

    Invoked to indicate a change in a propertyName of a Style

    NOTE By default this will trigger a call to `Container#revalidate()` on the parent container, which is expensive. You can disable this behavior by calling `CN.setProperty("Component.revalidateOnStyleChange", "false")`. The intention is to change this behavior so that the default is to "not" revalidate on style change, so we encourage you to set this to "false" to ensure for future compatibility.

    ###### Parameters

    - `propertyName`: the property name that was changed

    - `source`: The changed Style object

    public void setHidden(boolean b, boolean changeMargin)

    Makes the components preferred size equal 0 when hidden and restores it to the default size when not. This method also optionally sets the margin to 0 so the component will be truly hidden. Notice that this might not behave as expected with scrollable containers or layouts that ignore preferred size.

    ###### Parameters

    - `b`: true to hide the component and false to show it

    - `changeMargin`: indicates margin should be set to 0

  - ### isHidden

    public boolean isHidden()

    Returns true if the component was explicitly hidden by the user. This method doesn't check if the parent component is hidden, so it is possible that the component would be hidden from the UI, but that this would still return true. Use `#isHidden(boolean)` with true to check also if the parent is hidden.

    ###### Returns

    true if the component is hidden, notice that the hidden property and visible property have different meanings in the API!

  - ### setHidden

    public void setHidden(boolean b)

    Makes the components preferred size equal 0 when hidden and restores it to the default size when not. Also toggles the UIID to "Container" and back to allow padding/margin to be removed. Since the visible flag just hides the component without "removing" the space it occupies this is the flag that can be used to truly hide a component within the UI. Notice that this might not behave as expected with scrollable containers or layouts that ignore preferred size.

    ###### Parameters

    - `b`: true to hide the component and false to show it

  - ### isHidden

    public boolean isHidden(boolean checkParent)

    Checks if the component is hidden. If checkParent is true, this also checks to see if the parent is hidden, and will return true if either this component is hidden, or the parent is hidden.

    ###### Parameters

    - `checkParent`: True to check if parent is hidden also.

    ###### Returns

    Returns true if the component is hidden.
