outputs a new ComboBox and shows it on the parent (a Frame or a Graph, main Graph if []).

name is its label text.

text is the standard text shown in the edit control when the ComboBox is created.

choices is a list of items from whom the user can select one.

onSelect is a Logo instructionlist which will be run when the user selects a choice.

onChange is a Logo instructionlist which will be run when the user changes the text in the edit control.

onEnter is a Logo instructionlist which will be run when the user presses the [Enter] key.



style is the window style and can be a combination of the following constants:

wxCB_SIMPLE Creates a ComboBox with a permanently displayed list. Windows only.

wxCB_DROPDOWN Creates a ComboBox with a drop-down list.

wxCB_READONLY Same as wxCB_DROPDOWN but only the strings specified as the ComboBox choices can be selected, it is impossible to select (even from a program) a string which is not in the choices list.

wxCB_SORT Sorts the entries in the list alphabetically.



pos is the position of the ComboBox (a list of two integer numbers, x and y),

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

Example: 

cb=(ComboBox [][MyComboBox][Initial string]
	[	[String 1]
		[and a second string]
		[and the last string]
	]
	[	(show "|MyComboBox| ComboBoxSelection)
	]
	[	(pr [change] ComboBoxValue)
	]
	[	v=ComboBoxValue
		(pr [enter] v)
		ComboBoxAppend cb v
	]
	wxCB_simple [-1 -1][300 200])
