BasicTextFieldUI

public BasicTextFieldUI()

Creates a new BasicTextFieldUI.

createUI

public static ComponentUI createUI(JComponent c)

Creates a UI for a JTextField.

Parameters:

c - the text field

Returns:

the UI

installUI

 
public void installUI ( JComponent c) 

Description copied from class: BasicTextUI

Installs the UI for a component. This does the following things.

1. Set the associated component to opaque (can be changed easily by a subclass or on JTextComponent directly), which is the most common case. This will cause the component's background color to be painted.
2. Install the default caret and highlighter into the associated component.
3. Attach to the editor and model. If there is no model, a default one is created.
4. create the view factory and the view hierarchy used to represent the model.

Overrides:

installUI in class BasicTextUI

Parameters:

c - the editor component

See Also:

ComponentUI.installUI(javax.swing.JComponent)

propertyChange

 
protected void propertyChange ( PropertyChangeEvent evt) 

This method gets called when a bound property is changed on the associated JTextComponent. This is a hook which UI implementations may change to reflect how the UI displays bound properties of JTextComponent subclasses.

Overrides:

propertyChange in class BasicTextUI

Parameters:

evt - the property change event

getPropertyPrefix

protected String getPropertyPrefix()

Fetches the name used as a key to lookup properties through the UIManager. This is used as a prefix to all the standard text properties.

Specified by:

getPropertyPrefix in class BasicTextUI

Returns:

the name ("TextField")

create

public View create(Element elem)

Creates a view (FieldView) based on an element.

Specified by:

create in interface ViewFactory

Overrides:

create in class BasicTextUI

Parameters:

elem - the element

Returns:

the view

getBaseline

public int getBaseline(JComponent c,
                       int width,
                       int height)

Returns the baseline.

Overrides:

getBaseline in class ComponentUI

Parameters:

c - JComponent baseline is being requested for

width - the width to get the baseline for

height - the height to get the baseline for

Returns:

baseline or a value < 0 indicating there is no reasonable baseline

Throws:

NullPointerException - if c is null

IllegalArgumentException - if width or height is < 0

Since:

1.6

See Also:

JComponent.getBaseline(int, int)

getBaselineResizeBehavior

public Component.BaselineResizeBehavior getBaselineResizeBehavior(JComponent c)

Returns an enum indicating how the baseline of the component changes as the size changes.

Overrides:

getBaselineResizeBehavior in class ComponentUI

Parameters:

c - JComponent to return baseline resize behavior for

Returns:

an enum indicating how the baseline changes as the component size changes

Throws:

NullPointerException - if c is null

Since:

1.6
