Methods
public boolean
contains
(
JComponent c,
int x,
int y)
[Inherited From ComponentUI]
Returns
true if the specified
x,y location is
contained within the look and feel's defined shape of the specified
component.
Returns
true if the specified
x,y location is
contained within the look and feel's defined shape of the specified
component.
x and
y are defined to be relative
to the coordinate system of the specified component. Although
a component's
bounds is constrained to a rectangle,
this method provides the means for defining a non-rectangular
shape within those bounds for the purpose of hit detection.
Parameters:
-
c - the component where the
x,y location is being queried;
this argument is often ignored,
but might be used if the UI object is stateless
and shared by multiple components
-
x - the
x coordinate of the point
-
y - the
y coordinate of the point

Component.AccessibleAWTComponent.getAccessibleChild() instead of
this method.

getBaseline
(
JComponent c,
int width,
int height)
[Inherited From ComponentUI]
Returns the baseline.
Returns the baseline. The baseline is measured from the top of
the component. This method is primarily meant for
LayoutManagers to align components along their
baseline. A return value less than 0 indicates this component
does not have a reasonable baseline and that
LayoutManagers should not align this component on
its baseline.
This method returns -1. Subclasses that have a meaningful baseline
should override appropriately.
Returns:
baseline or a value < 0 indicating there is no reasonable
baseline
Parameters:
- c - JComponent baseline is being requested for
- width - the width to get the baseline for
- height - the height to get the baseline for
Throws:
- NullPointerException - if c is null
- IllegalArgumentException - if width or height is < 0
Since:
1.6

(

Returns an enum indicating how the baseline of he component
changes as the size changes. This method is primarily meant for
layout managers and GUI builders.
This method returns BaselineResizeBehavior.OTHER.
Subclasses that support a baseline should override appropriately.
Returns:
an enum indicating how the baseline changes as the component
size changes
Parameters:
- c - JComponent to return baseline resize behavior for
Throws:
- NullPointerException - if c is null

update
(
Graphics g,
JComponent c)
[Inherited From ComponentUI]
Notifies this UI delegate that it's time to paint the specified
component.
Notifies this UI delegate that it's time to paint the specified
component. This method is invoked by
JComponent when the specified component is being painted.
By default this method will fill the specified component with
its background color (if its
opaque property is
true) and then immediately call
paint.
In general this method need not be overridden by subclasses;
all look-and-feel rendering code should reside in the
paint method.
Parameters:
-
g - the
Graphics context in which to paint
-
c - the component being painted;
this argument is often ignored,
but might be used if the UI object is stateless
and shared by multiple components
