          org.eclipse.draw2d.FreeformLayout

All Implemented Interfaces:

LayoutManager

public class FreeformLayout
extends XYLayout

A layout for FreeformFigures. Supports option to set only positive (x,y) coordinates for children figures.

Constructor Summary

FreeformLayout()

Method Summary

Point	getOrigin(IFigure figure) Returns the point (0,0) as the origin.
void	invalidate() Tells the LayoutManager to throw away all cached information about the figures it is responsible for.
boolean	isPositiveCoordinates() Checks whether the positive coordinates flag is on, e.g positive coordinates for children are inforced by the layout
void	setPositiveCoordinates(boolean positiveCoordinates) Sets/unsets the positive coordinates flag for true/false parameters respectively.

Method Detail

getOrigin

public Point getOrigin(IFigure figure)

Returns the point (0,0) as the origin.

Overrides:

getOrigin in class XYLayout

Parameters:

figure - the figure whose origin is requested

Returns:

the origin

See Also:

XYLayout.getOrigin(IFigure)

isPositiveCoordinates

public boolean isPositiveCoordinates()

Checks whether the positive coordinates flag is on, e.g positive coordinates for children are inforced by the layout

Returns:

boolean

Since:

3.6

setPositiveCoordinates

public void setPositiveCoordinates(boolean positiveCoordinates)

Sets/unsets the positive coordinates flag for true/false parameters respectively. If option is set to on then layout calculates positive coordinates for children figures by adjusting the layout origin accordingly.

Parameters:

positiveCoordinates -

Since:

3.6

invalidate

public void invalidate()

Description copied from interface: LayoutManager

Tells the LayoutManager to throw away all cached information about the figures it is responsible for. This method is called whenever the owning figure is invalidated.

Specified by:

invalidate in interface LayoutManager

Overrides:

invalidate in class AbstractLayout
