create

public com.google.gwt.core.client.JavaScriptObject create()

Overrides:

create in class DrawItem

setHeight

public void setHeight(int height)
               throws java.lang.IllegalStateException

Height in pixels.

Parameters:

Parameters:

left - Default value is 0

getLeft

public int getLeft()

Left coordinate in pixels relative to the DrawPane.

Returns:

int

setSrc

public void setSrc(java.lang.String src)

URL to the image file.

If this method is called after the component has been drawn/initialized: Change the URL of the image displayed.

Parameters:

getCenter

public Point getCenter()

Get the center point of the image.

Returns:

the center point

moveBy

public void moveBy(int dX,
          int dY)

Move the drawImage by the specified delta

Overrides:

moveBy in class DrawItem

Parameters:

dX - number of pixels to move horizontally

dY - number of pixels to move vertically

moveTo

public void moveTo(int left,
          int top)

Move the drawImage to the specified position

Parameters:

left - new left coordinate

top - new top coordinate

setDefaultProperties

public static void setDefaultProperties(DrawImage drawImageProperties)

Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

Parameters:

drawImageProperties - properties that should be used as new defaults when instances of this class are created
