public class NumericStateButton

extends StateButton

implements java.awt.event.MouseListener

a button to display and select a numerical value.

This button implements the xfig-style behaviour to select a value: left button opens a dialog window for direct value input, middle and right button select the previous and next value, where an array of "stepping values" can be preset. Note that the "state" variable of our parent class is used as the value.

Constructor Detail

NumericStateButton

public NumericStateButton(java.awt.Component parent,
                          java.lang.String label,
                          StatusMessage helper,
                          java.lang.String helpMessage)

Method Detail

setState

public void setState(int i)

Description copied from class: StateButton

set the (initial) state for this button

Overrides:

setState in class StateButton

setMinValue

public void setMinValue(int min)

setMaxValue

public void setMaxValue(int max)

setSteps

public void setSteps(int[] steps)

set the "stepping" values for the increment/decrement function of this button. The "steps" array must be sorted by ascending values. To get consistent behaviour, this method automatically sets the minValue to steps[0] and maxValue to steps[length-1].

incrementStepValue

public void incrementStepValue()

increment the current value of this button by one step. If no "steps" values are set, this increments the value by one, until the maximum value is reached. If the "steps" array is not empty, the value is set to the next larger value than the current value, or wraparound to the minimum value if the button value is currently at the maximum value.

decrementStepValue

public void decrementStepValue()

calculateSize

public void calculateSize()

Overrides:

calculateSize in class StateButton

paint

public void paint(java.awt.Graphics g)

paint this custom button.

Overrides:

paint in class StateButton

mousePressed

public void mousePressed(java.awt.event.MouseEvent evt)

Specified by:

mousePressed in interface java.awt.event.MouseListener

Overrides:

mousePressed in class StateButton

toString

public java.lang.String toString()

the usual info method

Overrides:

toString in class StateButton

main

public static void main(java.lang.String[] argv)

simple selftest
