Constructor Detail

TreeDropLocationPainter

public TreeDropLocationPainter()

Method Detail

getDecorationStates

protected java.util.List<java.lang.String> getDecorationStates()

Description copied from class: AbstractDecorationPainter

Returns current component decoration states.

Overrides:

getDecorationStates in class AbstractSectionDecorationPainter<E extends javax.swing.JTree,U extends WebTreeUI,D extends IDecoration<E,D>>

Returns:

current component decoration states

prepareToPaint

public void prepareToPaint(javax.swing.JTree.DropLocation location)

Description copied from interface: ITreeDropLocationPainter

Prepares painter to paint tree drop location.

Specified by:

prepareToPaint in interface ITreeDropLocationPainter<E extends javax.swing.JTree,U extends WebTreeUI>

Parameters:

location - drop location

adjustBounds

protected java.awt.Rectangle adjustBounds(java.awt.Rectangle bounds)

Description copied from class: AbstractDecorationPainter

Returns adjusted painting bounds.

Overrides:

adjustBounds in class AbstractDecorationPainter<E extends javax.swing.JTree,U extends WebTreeUI,D extends IDecoration<E,D>>

Parameters:

bounds - painting bounds to adjust

Returns:

adjusted painting bounds

isPlainBackgroundPaintAllowed

protected boolean isPlainBackgroundPaintAllowed(E c)

Description copied from class: AbstractDecorationPainter

Returns whether or not painting plain component background is allowed. Moved into separated method for convenient background painting blocking using additional conditions.

By default this condition is limited to component being opaque. When component is opaque we must fill every single pixel in its bounds with something to avoid issues.

Overrides:

isPlainBackgroundPaintAllowed in class AbstractDecorationPainter<E extends javax.swing.JTree,U extends WebTreeUI,D extends IDecoration<E,D>>

Parameters:

c - component to paint background for

Returns:

true if painting plain component background is allowed, false otherwise

isDecorationPaintAllowed

protected boolean isDecorationPaintAllowed(D decoration)

Description copied from class: AbstractDecorationPainter

Returns whether or not painting specified decoration is allowed. Moved into separated method for convenient decorationg painting blocking using additional conditions.

By default this condition is limited to decoration existance and visibility.

Overrides:

isDecorationPaintAllowed in class AbstractDecorationPainter<E extends javax.swing.JTree,U extends WebTreeUI,D extends IDecoration<E,D>>

Parameters:

decoration - decoration to be painted

Returns:

true if painting specified decoration is allowed, false otherwise

getDropViewBounds

public java.awt.Rectangle getDropViewBounds(javax.swing.JTree.DropLocation location)

Description copied from interface: ITreeDropLocationPainter

Returns drop view bounds.

Specified by:

getDropViewBounds in interface ITreeDropLocationPainter<E extends javax.swing.JTree,U extends WebTreeUI>

Parameters:

location - drop location

Returns:

drop view bounds

isDropBetween

protected boolean isDropBetween(javax.swing.JTree.DropLocation location)

Returns whether the specified drop location should be displayed as line or not.

Parameters:

location - drop location

Returns:

true if the specified drop location should be displayed as line, false otherwise

getDropOnViewBounds

protected java.awt.Rectangle getDropOnViewBounds(javax.swing.JTree.DropLocation location)

Returns drop ON view bounds.

Parameters:

location - drop location

Returns:

drop ON view bounds

getDropBetweenViewBounds

Returns drop BETWEEN view bounds.

Parameters:

location - drop location

Returns:

drop BETWEEN view bounds
