public void setStateIcons(java.util.Map<java.lang.String,NinePatchIcon> stateIcons)

Sets states map.

Parameters:

stateIcons - states map

addStateIcon

public void addStateIcon(java.lang.String state,
                NinePatchIcon ninePatchIcon)

bounds - bounds for painter visual data

c - component to process

isFocused

protected boolean isFocused(E component)

Returns whether component is in focused state or not.

Parameters:

protected NinePatchIcon getComponentBackground(E component)

Returns current state icon for the specified component.

Parameters:

component - component to process

Returns:

current state icon

getButtonBackground

protected NinePatchIcon getButtonBackground(javax.swing.AbstractButton button)

Returns current state icon for the specified button.

Parameters:

button - button to process

Returns:

current state icon

getToolBarBackground

protected NinePatchIcon getToolBarBackground(javax.swing.JToolBar toolbar)

Returns current state icon for the specified toolbar.

Parameters:

toolbar - toolbar to process

Returns:

current state icon

getExactStateIcon

public NinePatchIcon getExactStateIcon(java.lang.String state)

Returns exact state icon or null if it is not specified.

Parameters:

c - component to process

Returns:

preferred size required for proper painting of visual data provided by this painter

getMargin

public java.awt.Insets getMargin(E c)

Returns margin required for visual data provided by this painter. This margin is usually added to component's margin when the final component border is calculated. You may pass null instead of zero margin - it will simply be ignored in that case.

Specified by:
