A generic toolkit class that provides both VM-specific support to other AFC classes and helper objects that assist with tasks such as dialog loading and image loading.

The FxToolkit class specifically supports other classes in the AFC as follows:

Provides a system interface for the current platform
.
Provides UIHelper.
        This is a frame object that can be used for things such as dialog loading and
        image loading, where a helper frame is required. 

Methods

createImage

public static Image createImage(ImageProducer ip);

Creates an image based on the given ImageProducer.

Return Value:

Returns an Image object.

Parameter	Description
ip	The ImageProducer object to base the image on.

createImage

public static Image createImage(int width, int height);

Creates an image with the specified width and height.

Return Value:

Returns an Image object.

Parameter	Description
width	The width of the image (in pixels).
height	The height of the image (in pixels).

getHelperFrame

public final static Frame getHelperFrame();

Retrieves a helper java.awt.Frame. This is used in loading images, loading dialogs, and so on.

Return Value:

Returns a Frame object that serves as a helper to other objects.

getHelperUIFrame

public final static UIFrame getHelperUIFrame();

Retrieves a helper frame. This is used in loading images, loading dialogs, and so on.

Return Value:

Returns a UIFrame object that serves as a helper to other objects.

getNumSystemColors

public final static int getNumSystemColors();

Retrieves the current number of system colors available.

Return Value:

Returns the current number of system colors available.

getNumSystemMetrics

public final static int getNumSystemMetrics();

Retrieves the current number of system metrics.

Return Value:

Returns the current number of system metrics.

getSystemColor

public final static Color getSystemColor(int index);

Retrieves a system color in a platform-independent way.

Return Value:

Returns the system Color specified by the index.

Parameter	Description
index	The index of the system color to retrieve.

Exceptions:

ArrayOutOfBoundsException if the index is not valid.

getSystemInterface

public final static IFxSystemInterface getSystemInterface();

Retrieves an instance of one of the system interface classes.

Return Value:

Returns a system interface.

Remarks:

This static method returns an instance of an IFxSystemInterface class, based on the current platform. For example, if AFC is running on a JDK 1.1 compliant Virtual Machine, the method returns a system interface for JDK 1.1. These classes are used internally and are not used directly by applications. Use this method to retrieve the system interface before you call any other non-static method in the FxToolkit class.

getSystemMetric

public final static int getSystemMetric(int index);

Retrieves a system metric at the given index in a platform-independent way.

Return Value:

Returns the system metric at the specified index.

Parameter	Description
index	The index of the system metric to retrieve.

Exceptions:

ArrayOutOfBoundsException if the index is not valid.

getWidgetFont

public final static Font getWidgetFont(int size);

Retrieves the font that contains the bits of the widget font. On the Win32 platform, this is the Marlett font, but other platforms typically do not define widget, in which case null is returned. In this case, widget glyphs will be created via a standard algorithm.

Return Value:

Returns the widget font if defined; otherwise, returns null.

Parameter	Description
size	The size of the font (in points).
