Constructor Detail

SyntheticaBasicIconPainter

public SyntheticaBasicIconPainter()

Constructor for 16x16 pixel icon.

SyntheticaBasicIconPainter

public SyntheticaBasicIconPainter(javax.swing.plaf.synth.SynthContext sc,
                                  int width,
                                  int height)

Constructor.

Parameters:

sc - SynthContext - can be null.

width - The icon width.

height - The icon height.

Method Detail

getScale

protected float getScale()

Returns the current scale factor.

createStroke

protected java.awt.BasicStroke createStroke(javax.swing.plaf.synth.SynthContext sc)

Creates the stroke used for Java2D painting.

getIconHeight

public int getIconHeight()

Specified by:

getIconHeight in interface javax.swing.Icon

getIconWidth

public int getIconWidth()

Specified by:

getIconWidth in interface javax.swing.Icon

paintIcon

public void paintIcon(java.awt.Component c,
                      java.awt.Graphics g,
                      int x,
                      int y)

Specified by:

paintIcon in interface javax.swing.Icon

paintIcon

public void paintIcon(javax.swing.plaf.synth.SynthContext sc,
                      java.awt.Graphics g,
                      int x,
                      int y,
                      int w,
                      int h)

paint2D

public void paint2D(javax.swing.plaf.synth.SynthContext sc,
                    java.awt.Graphics2D g2,
                    float x,
                    float y,
                    float w,
                    float h)

Paint non-scaled icon with Java2D. Default implementation does nothing. Override and implement painting code. Width and height returns original values minus 1 which is useful because the stroke line width is 1 in most cases. If a custom stroke is used the helper method calc2DBounds(Graphics2D, float, float) can be used to calculate x,y,w,h in respect of the stroke line width.

Parameters:

sc - SynthContext - can be null.

g2 - Graphics.

x - Original non-scaled X-position. If paint2D(SynthContext, Graphics2D, float, float, float, float) isn't overridden the X-position can be ignored because point of origin is translated to X,Y by the default implementation.

y - Original non-scaled Y-position. If paint2D(SynthContext, Graphics2D, float, float, float, float) isn't overridden the Y-position can be ignored because point of origin is translated to X,Y by the default implementation.

w - Non-scaled width-1.

h - Non-scaled height-1.

Calculates outer shape bounds in respect of the stroke width.

Parameters:

w - Non-scaled width-1.
