CheckBox parent alabel onclick
(CheckBox parent alabel onclick style apos size)

outputs a new CheckBox on the parent (a Frame or a Graph),

having the text alabel on it,

and running the onclick instructionlist when the user clicks with the mouse on it.



style can be a combination (use +) of the following constants:

wxCHK_2STATE Create a 2-state checkbox. This is the default.

wxCHK_3STATE Create a 3-state checkbox. Not implemented in wxMGL, wxOS2 and wxGTK built against GTK+ 1.2.

wxCHK_ALLOW_3RD_STATE_FOR_USER By default a user can't set a 3-state checkbox to the third state. It can only be done from code. Using this flags allows the user to set the checkbox to the third state by clicking.

wxALIGN_RIGHT Makes the text appear on the left of the checkbox.



apos is the position of the Button (a list of two integer numbers, x and y),

size is the size of the Button (again a list of two integer numbers, width and height).

Examples: 

cbpd=CheckBox [][Pen Down][
	ifelse CheckBoxValue cbpd [PenDown][PenUp]
	updateGraph]
cbht=(CheckBox [][Hide Turtle][
	ifelse CheckBoxValue cbht [hideTurtle][showTurtle]
	updateGraph]
	wxBU_LEFT+wxBU_TOP [0 100][200 100])
