Method Detail

paint

public void paint(javax.microedition.lcdui.Graphics g,
                  javax.microedition.lcdui.Gauge gg,
                  int width,
                  int height,
                  java.util.TimerTask tt,
                  boolean hasFocus)

Method to be used for drawing a Gauge.

Parameters:

g - Graphics object to use for drawing

gg - Gauge to draw

width - Assigned width of the Gauge, in pixels

height - Assigned height of the Gauge, in pixels

tt - TimerTask used for animation

hasFocus - true if the Gauge has cursor focus

getMinimumHeight

public int getMinimumHeight(javax.microedition.lcdui.Gauge gg)

Get the minimum height of this component

Parameters:

gg - Gauge to obtain size information about

Returns:

minimum height, in pixels

getMinimumWidth

public int getMinimumWidth(javax.microedition.lcdui.Gauge gg)

Get the minimum width of this component

Parameters:

gg - Gauge to obtain size information about

Returns:

minimum width, in pixels

getPreferredHeight

public int getPreferredHeight(javax.microedition.lcdui.Gauge gg,
                              int width)

Get the preferred height of this component

Parameters:

gg - Gauge to obtain size information about

width - the tentative content width in pixels, or -1 if a tentative width has not been computed

Returns:

preferred height, in pixels

getPreferredWidth

public int getPreferredWidth(javax.microedition.lcdui.Gauge gg,
                             int height)

Get the preferred width of this component

Parameters:

gg - Gauge to obtain size information about

height - the tentative content height in pixels, or -1 if a tentative height has not been computed

Returns:

preferred width, in pixels

getUpdatedValue

public int getUpdatedValue(int x,
                           int y,
                           javax.microedition.lcdui.Gauge gg,
                           boolean isRelease)

Figure out what the new Gauge value is when a pointer action occurs.

Parameters:

x - The x position of the pointer action

y - The y position of the pointer action

gg - Gauge which was pressed

isRelease - true if the event was a pointer release, in this case the value must be updated

Returns:

the new Gauge value

updateAnimation
