Constructor Details

ButtonBorder

public ButtonBorder(Color shadow,
                    Color darkShadow,
                    Color highlight,
                    Color lightHighlight)
Constructs a new border for drawing a button in the Basic look and feel.

shadow - the shadow color.
darkShadow - a darker variant of the shadow color.
highlight - the highlight color.
lightHighlight - a brighter variant of the highlight color.

Method Details

getBorderInsets

public Insets getBorderInsets(Component c)
Measures the width of this border.

Although the thickness of the actually painted border depends on the state of the enclosed component, this measurement always returns the same amount of pixels. Indeed, it would be rather confusing if a button was appearing to change its size depending on whether it is pressed or not.

Specified by:
getBorderInsets in interface Border
Overrides:
getBorderInsets in interface AbstractBorder
Parameters:
c - the component whose border is to be measured.
Returns:
an Insets object whose left, right, top and bottom fields indicate the width of the border at the respective edge.

getBorderInsets

public Insets getBorderInsets(Component c,
                              Insets insets)
Measures the width of this border, storing the results into a pre-existing Insets object.

Although the thickness of the actually painted border depends on the state of the enclosed component, this measurement always returns the same amount of pixels. Indeed, it would be rather confusing if a button was appearing to change its size depending on whether it is pressed or not.

Overrides:
getBorderInsets in interface AbstractBorder
Parameters:
insets - an Insets object for holding the result values. After invoking this method, the left, right, top and bottom fields indicate the width of the border at the respective edge.
Returns:
the same object that was passed for insets.

paintBorder

public void paintBorder(Component c,
                        Graphics g,
                        int x,
                        int y,
                        int width,
                        int height)
Paints the ButtonBorder around a given component.
Specified by:
paintBorder in interface Border
Overrides:
paintBorder in interface AbstractBorder
Parameters:
c - the component whose border is to be painted.
g - the graphics for painting.
x - the horizontal position for painting the border.
y - the vertical position for painting the border.
width - the width of the available area for painting the border.
height - the height of the available area for painting the border.
