Constructor Detail

JCCircularNeedle

public JCCircularNeedle(com.klg.jclass.swing.gauge.JCCircularScale scale)

Creates a needle.

Parameters:

scale - The associated circular scale

JCCircularNeedle

public JCCircularNeedle(Color foreground,
                        double needleWidth,
                        com.klg.jclass.swing.gauge.JCCircularScale scale,
                        boolean visible,
                        double inner_extent,
                        double outer_extent,
                        com.klg.jclass.swing.gauge.JCIndicatorStyle needleStyle,
                        double value)

Creates a needle.

Parameters:

foreground - the needle's color

needleWidth - the needle's width in pixels

scale - the associated circular scale

visible - a Boolean that controls the visibility of the needle

inner_extent - the needle's inner extent, expressed as a ratio of its length to the relevant dimension (radius, width/length) of the associated circular scale

outer_extent - the needle's outer extent, expressed as a ratio of its length to the relevant dimension (radius, width/length) of the associated circular scale

needleStyle - needle styles are kept in JCIndicatorStyle; user-defined needle styles may be passed to JCIndicatorStyle's constructor

value - the needle's value; the needle points to this value on its associated scale

JCCircularNeedle

public JCCircularNeedle(Color foreground,
                        double needleWidth,
                        com.klg.jclass.swing.gauge.JCCircularScale scale,
                        JCAbstractNeedle.InteractionType interactionType,
                        boolean visible,
                        double length,
                        com.klg.jclass.swing.gauge.JCIndicatorStyle needleStyle,
                        double value)

Deprecated. Beginning with JClass 5, the length parameter has been replaced with inner_extent and outer_extent.

Creates a needle.

Parameters:

foreground - the needle's color

needleWidth - the needle's width in pixels

scale - the associated circular scale

interactionType - the interaction type; CLICK, CLICK_DRAG, or NONE

visible - a Boolean that controls the visibility of the needle

length - the needle's length, expressed as a ratio of its length to the relevant dimension (radius, width/length) of the associated scale

needleStyle - needle styles are kept in JCIndicatorStyle; user-defined needle styles may be passed to JCIndicatorStyle's constructor

value - the needle's value; the needle points to this value on its associated scale
