Detailed Description

The core class for the global manipulation and execution of G4P.
All the methods and constants are static so to call a method or reference a constant prefix it's name with 'G4P.' for example

G4P.method_name(parameters);
G4P.name_of_constant;


Please note that the methods

selectColor(...)
selectFolder(...)
selectInput(...)
selectOutput(...)

are provided modal alternatives to those provided in Processing 3 and only work in JAVA2D mode.
They are provided as-is and have not been tested on all platforms. If they don't work for you then use those provided by Processing.

Get an array of GWindow objects even if minimised or invisible.
This method never returns null, if there are no open windows the array will be of length zero.

Returns
an array of references to all open GWindow objects.

◆ getOpenWindowsAsList()

static ArrayList< GWindow > g4p_controls.G4P.getOpenWindowsAsList ( ArrayList< GWindow list)
static

Get a list of all open GWindow objects even if minimised or invisible.
If an ArrayList is provided then its contents are cleared before adding references to all open GWindow objects. If an ArrayList is not provided then a new ArrayList will be created.
This method never returns null, if there are no open windows the list will be of size zero.

Parameters
listan optional ArrayList to use. In null will create a new ArrayList.
Returns
an ArrayList of references to all open GWindow objects.

◆ getPrettyVersion()

static String g4p_controls.G4P.getPrettyVersion ( )
static
Returns
the pretty version of the library. This will be shown in Processing

◆ getVersion()

static String g4p_controls.G4P.getVersion ( )
static
Returns
the version of the library.

◆ isWindowOpen()

static boolean g4p_controls.G4P.isWindowOpen ( GWindow  window)
static

Use this to check whether a GWindow window is still open (as far as G4P is concerned).

Parameters
windowthe window we are interested in
Returns
true if G4P still thinks it is open

◆ messagesEnabled()

static void g4p_controls.G4P.messagesEnabled ( boolean  enable)
static

G4P has a range of support messages eg
if you create a GUI component without an event handler or,
a slider where the visible size of the slider is less than the difference between min and max values.

This method allows the user to enable (default) or disable this option. If disable then it should be called before any GUI components are created.

If you are adding your own event handlers then I suggest that you disable messages.

Parameters
enablewhether to enable messages or not

◆ mouseWheelScrollbarDirection()

static void g4p_controls.G4P.mouseWheelScrollbarDirection ( int  dir)
static

Determines how the direction of the mouse wheel rotation is interpreted for sliders. This value applies to all sliders.
The default value is FORWARD

Parameters
dirFORWARD or REVERSE, illegal values are ignored

◆ mouseWheelSliderDirection()

static void g4p_controls.G4P.mouseWheelSliderDirection ( int  dir)
static

Determines how the direction of the mouse wheel rotation is interpreted for sliders and knobs. This value applies to all sliders and knobs.
The default value is FORWARD

Parameters
dirFORWARD or REVERSE, illegal values are ignored

◆ mouseWheelSpinnerDirection()

static void g4p_controls.G4P.mouseWheelSpinnerDirection ( int  dir)
static

Determines how the direction of the mouse wheel rotation is interpreted for spinners. This value applies to all spinners.
The default value is FORWARD

Parameters
dirFORWARD or REVERSE, illegal values are ignored

◆ registerSketch()

static void g4p_controls.G4P.registerSketch ( PApplet  app)
static

Used to register the main sketch window with G4P. This is ignored if any G4P controls or windows have already been created because the act of creating a control will do this for you.

Some libraries such as PeasyCam change the transformation matrix when initiated. In which case either a G4P control should be created or this method called before creating a PeasyCam object.

Parameters
appthe main sketch PApplet usually 'this'

Select a file for input from the local file system.

This version allows the dialog window to filter the output based on file extensions. This is not available on all platforms, if not then it is ignored.

It is definitely available on Linux systems because it uses the standard Swing JFileFinder component.

Parameters
promptthe frame text for the chooser
typesa comma separated list of file extensions e.g. "png,gif,jpg,jpeg"
typeDescsimple textual description of the file types e.g. "Image files"

◆ selectOption()

static int g4p_controls.G4P.selectOption ( PApplet  owner,
String  message,
String  title,
int  messageType,
int  optionType 
)
static

Display a simple message dialog window.

The actual UI will depend on the platform your application is running on.

The message type should be one of the following
G4P.PLAIN_MESSAGE, G4P.ERROR_MESSAGE, G4P.INFO_MESSAGE, G4P.WARN_MESSAGE, G4P.QUERY_MESSAGE

The option type should be one of the following
G4P.YES_NO, G4P.YES_NO_CANCEL, G4P.OK_CANCEL

This method returns a value to indicate which button was clicked. It will be one of the following
G4P.OK, G4P.YES, G4P.NO, G4P.CANCEL, G4P.CLOSED

Some comments on the returned value:

  • G4P.OK and G4P.YES have the same integer value so can be used interchangeably.
  • G4P.CLOSED maybe returned if the dialog box is closed although on some systems G4P.NO or G4P.CANCEL may be returned instead.
  • It is better to test for a positive response because they have the same value.
  • If you must test for a negative response use !G4P.OK or !G4P.YES
Parameters
ownerthe control responsible for this dialog.
messagethe text to be displayed in the main area of the dialog
titlethe text to appear in the dialog's title bar.
