g4p_controls

Class GCScheme

java.lang.Object

g4p_controls.GCScheme

All Implemented Interfaces:

GConstants, processing.core.PConstants

public class GCScheme
extends java.lang.Object
implements GConstants, processing.core.PConstants

Defines a number of color schemes for the GUI components.
G4P supports 16 colour schemes and each scheme has a palette of 16 colours.
When G4P is used it loads an image file with all the colors used by the various colour schemes.
First it will search for a file containing a user defined scheme (user_gui_palette.png) and if it can't find it, will use the library default scheme (default_gui_palette.png).

Method Detail

getPalette

public static int[] getPalette(int schemeNbr)

Set the color scheme to one of the preset schemes BLUE / GREEN / RED / PURPLE / YELLOW / CYAN / BROWN or if you have created your own schemes following the instructions at gui4processing.lagers.org.uk/colorscheme.html then you can enter the appropriate numeric value of the scheme.

Parameters:

schemeNbr - scheme number (0-15)

Returns:

the color scheme based on the scheme number

changePalette

public static void changePalette(int schemeNbr,
                 int[] colors)

Change a colour scheme to use the colours passed in the third parameter.
Colour scheme numbers 0-7 inclusive are the default colour schemes and schemes 8-15 inclusive are undefined by G4P.
This method will override the previous scheme and will affect all controls using the scheme.

Parameters:

schemeNbr - the scheme number

colors - the colours to use in this palette.

copyPalette

public static void copyPalette(int srcSchemeNbr,
               int dstSchemeNbr)

Copies the colours from the source scheme to the destination scheme.

Parameters:

srcSchemeNbr - source scheme number (0-15)

dstSchemeNbr - destination scheme number (0-15)

changePaletteColor

public static void changePaletteColor(int schemeNbr,
                      int colorNbr,
                      int color)

Change a single colour within an existing scheme

Parameters:

schemeNbr - the scheme number

colorNbr - the palette index number for the colour

color - ARGB colour value

savePalettes

public static void savePalettes(processing.core.PApplet app)

Save the current colour schemes as an image in the sketch's data folder. The file will be called

"user_gui_palette.png"

Parameters:

app - the PApplet object

savePalettes

public static void savePalettes(processing.core.PApplet app,
                java.lang.String filename)

Save the current colour schemes as an image in the sketch's data folder.

Parameters:

app - the PApplet object

filename - the name of the image file to use

makeColorSchemes

public static void makeColorSchemes(processing.core.PApplet app)

Called every time we create a control. The palettes will be made when the first control is created. This method is called by

Parameters:

app - the PApplet using this scheme

getJavaColor

public static java.awt.Color[] getJavaColor(int schemeNo)
