Field Detail

enableImageSupport

public static boolean enableImageSupport

Global switch to disable image support in transferables. Set this to false as a workaround for Data translation failed: not an image format in Java 1.7 on Mac OS X.

dataFlavor

public static DataFlavor dataFlavor

Serialized Data Flavor. Use the following code to switch to local reference flavor: try { mxGraphTransferable.dataFlavor = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType + "; class=com.mxgraph.swing.util.mxGraphTransferable"); } catch (ClassNotFoundException cnfe) { // do nothing } If you get a class not found exception, try the following instead: mxGraphTransferable.dataFlavor = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType + "; class=com.mxgraph.swing.util.mxGraphTransferable", null, new com.mxgraph.swing.util.mxGraphTransferable(null, null).getClass().getClassLoader());

cells

protected Object[] cells

bounds

protected mxRectangle bounds

image

protected ImageIcon image

Constructor Detail

mxGraphTransferable

public mxGraphTransferable(Object[] cells,
                           mxRectangle bounds)

mxGraphTransferable

public mxGraphTransferable(Object[] cells,
                           mxRectangle bounds,
                           ImageIcon image)

Method Detail

getCells

public Object[] getCells()

Returns:

Returns the cells.

getBounds

public mxRectangle getBounds()

Returns the unscaled, untranslated bounding box of the cells.

getImage

public ImageIcon getImage()

getTransferDataFlavors

public DataFlavor[] getTransferDataFlavors()

Specified by:

getTransferDataFlavors in interface Transferable

getRicherFlavors

protected DataFlavor[] getRicherFlavors()

Some subclasses will have flavors that are more descriptive than HTML or plain text. If this method returns a non-null value, it will be placed at the start of the array of supported flavors.

isDataFlavorSupported

public boolean isDataFlavorSupported(DataFlavor flavor)

Returns whether or not the specified data flavor is supported for this object.

Specified by:

isDataFlavorSupported in interface Transferable

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported

getTransferData

public Object getTransferData(DataFlavor flavor)
                       throws UnsupportedFlavorException,
                              IOException

Returns an object which represents the data to be transferred. The class of the object returned is defined by the representation class of the flavor.

Specified by:

getTransferData in interface Transferable

Parameters:

flavor - the requested flavor for the data

Throws:

IOException - if the data is no longer available in the requested flavor.

UnsupportedFlavorException - if the requested data flavor is not supported.

DataFlavor.getRepresentationClass()

isRicherFlavor

protected boolean isRicherFlavor(DataFlavor flavor)

Parameters:

flavor -

Returns:

Returns true if the given flavor is a richer flavor of this transferable.

getRicherData

public Object getRicherData(DataFlavor flavor)
                     throws UnsupportedFlavorException

Parameters:

flavor -

Returns:

the richer data flavor of this and the specified

Throws:

UnsupportedFlavorException

isHtmlFlavor

protected boolean isHtmlFlavor(DataFlavor flavor)

Returns whether or not the specified data flavor is an HTML flavor that is supported.

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported

isHtmlSupported

protected boolean isHtmlSupported()

Whether the HTML flavors are offered. If so, the method getHTMLData should be implemented to provide something reasonable.

getHtmlData

protected String getHtmlData()

Fetch the data in a text/html format

isImageFlavor

protected boolean isImageFlavor(DataFlavor flavor)

Parameters:

flavor -

Returns:

Returns true if the given flavor is an image flavor of this transferable.

isImageSupported

public boolean isImageSupported()

isPlainFlavor

protected boolean isPlainFlavor(DataFlavor flavor)

Returns whether or not the specified data flavor is an plain flavor that is supported.

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported

isPlainSupported

protected boolean isPlainSupported()

Whether the plain text flavors are offered. If so, the method getPlainData should be implemented to provide something reasonable.

getPlainData

protected String getPlainData()

Fetch the data in a text/plain format.

isStringFlavor

protected boolean isStringFlavor(DataFlavor flavor)

Returns whether or not the specified data flavor is a String flavor that is supported.

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported
