Detailed Description

Base class for independent windows using JAVA2D, P2D or P3D renderers. These can be used to hold G4P GUI components or used for drawing or both combined.

A number of examples are included in the library and more info can be found at www.lagers.org.uk

◆ addData()

void g4p_controls.GWindow.addData ( GWinData  data)

To provide a unique fields for this window create a class that inherits from GWinData with public access fields. Then use this method to associate the data with this window.

Parameters
datathe GWinData object associated with this window

◆ addDrawHandler()

void g4p_controls.GWindow.addDrawHandler ( Object  obj,
String  methodName 
)

Attempt to add the 'draw' handler method. The default event handler is a method that returns void and has two parameters PApplet and GWinData

Parameters
objthe object to handle the event
methodNamethe method to execute in the object handler class

◆ addKeyHandler()

void g4p_controls.GWindow.addKeyHandler ( Object  obj,
String  methodName 
)

Attempt to add the 'key' handler method. The default event handler is a method that returns void and has three parameters GWinApplet, GWinData and a KeyEvent

Parameters
objthe object to handle the event
methodNamethe method to execute in the object handler class

◆ addMouseHandler()

void g4p_controls.GWindow.addMouseHandler ( Object  obj,
String  methodName 
)

Attempt to add the 'mouse' handler method. The default event handler is a method that returns void and has three parameters GWinApplet, GWinData and a MouseEvent

Parameters
objthe object to handle the event
methodNamethe method to execute in the object handler class

◆ addOnCloseHandler()

void g4p_controls.GWindow.addOnCloseHandler ( Object  obj,
String  methodName 
)

Attempt to create the on-close-window event handler for this GWindow. The default event handler is a method that returns void and has a single parameter of type GWindow (this will be a reference to the window that is closing)

The handler will not be called if the setActionOnClose flag is set to EXIT_APP
If the flag is set to CLOSE_WINDOW then the handler is called when the window is closed by clicking on the window-close-icon or using either the close or forceClose methods.
If the flag is set to KEEP_OPEN the window can only be closed using the forceClose method. In this case the handler will be called.

Parameters
objthe object to handle the on-close-window event
methodNamethe method to execute in the object handler class

Parameters
objthe object to handle the event
methodNamethe method to execute in the object handler class

◆ addPreHandler()

void g4p_controls.GWindow.addPreHandler ( Object  obj,
String  methodName 
)

Parameters
objthe object to handle the event
methodNamethe method to execute in the object handler class

◆ addToWindow()
