Constructor Detail

SquareSonarBorder

public SquareSonarBorder(int innerColor,
                         int outerColor,
                         int steps,
                         int distance,
                         int pause,
                         int numSignals,
                         int speed)

Creates a new SquareSonarBorder

Parameters:

innerColor - the color at the inner starting point.

outerColor - the color at the outer end point.

steps - the number of animation steps required for moving from the inner point to the outer point

distance - the distance from the inner point to the outer point in pixels

pause - the pause in ms between different sonar signals

numSignals - the number of signals that are send out. Use -1 for not limiting the number.

speed - the constant speed by which signals move from the inner to the outer point - use -1 for moving fast in the beginning and then slowing down.

Method Detail

showNotify

public void showNotify()

Description copied from class: Border

Informs the border that it is being shown shortly or that it is now applied to a new visible item. The default implementation is empty.

Overrides:

showNotify in class Border

animate

public void animate(Screen screen,
                    Item parent,
                    long currentTime,
                    ClippingRegion repaintRegion)

Description copied from class: Border

Animates this background. Subclasses can override this method to create animations. The default implementation calls the animate() method and adds the full content area to the repaint region.

Overrides:

animate in class Border

Parameters:

screen - the parent screen

parent - the parent item, can be null when the background belongs to a screen

currentTime - the current time in milliseconds

repaintRegion - the repaint area that needs to be updated when this item is animated
