OVERVIEW<\/strong><\/p>\n\n\n\n

A wxCheckBox acts as a toggle control – either it is checked or not checked. We can set a 3-state checkbox as well, but that is non-standard and not supported in all platforms. By default the label will appear to the right of the checkbox, but this can be changed also.<\/p>\n\n\n\n
