Purpose |
To define a radio button or check box. |
|
Syntax |
winio@('%rb[button_text]', ctrl) |
|
Modifiers |
Grave accent (`) - provides a check box rather than a radio button. Caret (^) - call-back is called when the control is selected. Question mark (?) - a help string is supplied. Tilde (~) - adds a variable that controls the grey (enable/disable) state. |
|
Description |
button_text is a standard character string (can be replaced by @) for the text attached to the radio button. To change the text dynamically use %lc (Handle of Last Control) and the API function SetWindowText. ctrl is 1 (on) or 0 (off). grey_ctrl is 1 (enabled) or 0 (disable/greyed). A call-back function (if present) is placed after this control variable. %rb can be used in conjunction with the gang format code %ga (Gang Controls). Note that it is not conventional to gang check boxes. |

Example |
