copy

public final JaObject copy()

Returns an exact copy of this JaBlob.

Specified by:

copy in class JaObject

Returns:

A copy of this JaBlob.

isCopy

public final boolean isCopy(JaObject comp)

Returns true if all serializable variables of this JaObject and those of the specified one are equal.

Specified by:

isCopy in class JaObject

Parameters:

comp - A JaObject to compare with.

Returns:

True if the objects are equal, false otherwise.

drawVisualAid

public final void drawVisualAid(org.freehep.graphics2d.VectorGraphics g2)

Draws a visual aid during the dragging of a blob object, which is a red cross at the center.

Overrides:

drawVisualAid in class JaObject

Parameters:

g2 - The graphics context to draw to.

drawHandles

public final void drawHandles(org.freehep.graphics2d.VectorGraphics g2)

Draws a visual aid during the dragging of a blob object, which is a red cross at the center.

Specified by:

drawHandles in class JaObject

Parameters:

g2 - The graphics context to draw to

getGrabbedHandle

public final int getGrabbedHandle(int clickX,
                                  int clickY,
                                  int editmode)

Determines where on this JaObject a mouse click has ocurred.

Specified by:

getGrabbedHandle in class JaObject

Parameters:

clickX - The x position of the point where the mouse click ocurred.

clickY - The y position of the point where the mouse click ocurred.

editmode - The current edit mode as defined in JaxoMainPanel.

Returns:

An integer specifying whether the click ocurred on one of the handles and if yes, on which.

jaxoDraw

public final void jaxoDraw(org.freehep.graphics2d.VectorGraphics g2,
                           boolean drawToScreen)

The method that draws this JaBlob.

Specified by:

jaxoDraw in class JaObject

Parameters:

g2 - The graphics context where the JaBlob has to be drawn.

drawToScreen - A boolean variable that indicates whether the drawing is done on the screen or somewhere else. This is used for exporting/printing, where the object handles should not be painted, even if they are visible on the screen.

latexCommand

public final String latexCommand(float scale,
                                 Dimension canvasDim)

                                int ory,
                                float scale)

Rescales this JaBlob by the scale factor scale, keeping the point (orx, ory) fixed.

Specified by:

rescaleObject in class JaObject

Parameters:

orx - The x - coordinate of the fixed point

ory - The y - coordinate of the fixed point

scale - The scale parameter

editPanel

public final boolean editPanel()

Brings up the edit panel that allows to change the parameters of this object.

Specified by:

editPanel in class JaObject

Returns:

True if the editing actually changed the object, false if the object has not been changed.
