Constructor & Destructor Documentation

riverrat.RiverRatDemo.RiverRatDemo (   ) 
 

Default constructor.

Sets up new Race, initializes Map with defined coordinates, sets size to defined width and height, sets background color, and initializes application.

Definition at line 131 of file RiverRatDemo.java.

Member Function Documentation

void riverrat.RiverRatDemo.actionPerformed (  ActionEvent  e  ) 
 

This implements the ActionListener class, and allows Menus to send actions to the application.

Definition at line 159 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.drawArrows (  Graphics  g  ) 
 

This is a test method (unused) to draw a series of triangle boat icons at different headings, with 45 degree increments.

Parameters:
g Graphics object to draw on

Definition at line 253 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.drawBoat (  Graphics  g,
int  boatid
) 
 

Draws a certain boat from the race.

Parameters:
g Graphics object to draw on boatid int with id of mark to draw

Definition at line 417 of file RiverRatDemo.java.

References riverrat.Fix.fixToString(), riverrat.Fix.getLat(), and riverrat.Fix.getLon().

void riverrat.RiverRatDemo.drawBoatIcon (  Graphics  g,
int  x,
int  y,
float  radians
) 
 

Draws a boat-shaped boat icon at position (x,y), with heading radians, from 0 to 2Pi, on the Graphics object g.

x is measured from the left side of the window, y is measured from the top of the window. A heading of 0 draws an icon pointing north. Doesn't really work at the moment.

Parameters:
g Graphics object to draw to x int with x coordinates of center of icon y int with y coordinates of center of icon radians float with heading in radians

Definition at line 306 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.drawCursorLatLon (  Graphics  g  ) 
 

Draws a string with the cursor location in latitude and longitude.

Parameters:
g Graphics object to draw on

Definition at line 356 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.drawHelpMessage (  Graphics  g  ) 
 

Draws a help message to show keyboard commands.

Parameters:
g Graphics object to draw on

Definition at line 337 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.drawLatLonGrid (  Graphics  g  ) 
 

Draws a grid of vertical and horizontal lines.

Parameters:
g Graphics object to draw on

Definition at line 365 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.drawMark (  Graphics  g,
int  markid
) 
 

Draws a certain mark from the race.

Parameters:
g Graphics object to draw on markid int with id of mark to draw

Definition at line 387 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.drawTriangle (  Graphics  g,
int  x,
int  y,
float  radians
) 
 

Draws a triangular boat icon at position (x,y), with heading radians, from 0 to 2Pi, on the Graphics object g.

x is measured from the left side of the window, y is measured from the top of the window. A heading of 0 draws an icon pointing north.

Parameters:
g Graphics object to draw to x int with x coordinate of center of icon y int with y coordinate of center of icon radians float with heading in radians

Definition at line 277 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.keyTyped (  KeyEvent  e  ) 
 

Implements part of the KeyListener interface.

Listens for certain keys and triggers these behaviors.
P = Toggle Pointer Location
G = Toggle Grid
R = Toggle Race Status
B = Toggle Boat Status
H = Toggle Help

Definition at line 513 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.main (  String  args[]  )  [static]
 

This makes a new RiverRatDemo object, then goes into a loop sending a repaint() event every half-second.

Definition at line 545 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.mouseDragged (  MouseEvent  e  ) 
 

Part of the MouseMotionListener interface.

Updates internal variables describing the position of the mouse. This is used to display the pointer location on the screen.

Definition at line 239 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.mouseEntered (  MouseEvent  e  ) 
 

Unused part of the MouseListener interface.

Definition at line 196 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.mouseMoved (  MouseEvent  e  ) 
 

Part of the MouseMotionListener interface.

Updates internal variables describing the position of the mouse. This is used to display the pointer location on the screen.

Definition at line 226 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.mousePressed (  MouseEvent  e  ) 
 

Part of the MouseListener interface.

Simply changes an internal state variable describing the mouse status.

Definition at line 204 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.mouseReleased (  MouseEvent  e  ) 
 

Part of the MouseListener interface.

Simply changes an internal state variable describing the mouse status.

Definition at line 214 of file RiverRatDemo.java.

void riverrat.RiverRatDemo.paint (  Graphics  g  ) 
 

This is where the magic happens.

This paint() gets called to draw the appropriate stuff. This paint() then calls other methods, like drawBoat().

Parameters:
g Graphics object to draw on
