XmVaCreateSimpleCheckBox: A RowColumn widget convenience creation function
NAMEXmVaCreateSimpleCheckBox --- A RowColumn widget convenience creation function
#include <Xm/RowColumn.h> Widget XmVaCreateSimpleCheckBox( Widget parent, String name, XtCallbackProc callback);
XmVaCreateSimpleCheckBox creates an instance of a RowColumn widget of type XmWORK_AREA and returns the associated widget ID. This routine uses the ANSI C variable-length argument list (varargs) calling convention.
This routine creates a CheckBox and its ToggleButtonGadget children. A CheckBox is similar to a RadioBox, except that more than one button can be selected at a time. The name of each button is button_n, where n is an integer from 0 (zero) to the number of buttons in the menu minus 1. Buttons are named and created in the order in which they are specified in the variable portion of the argument list.
- Specifies the parent widget ID.
- Specifies the name of the created widget.
- Specifies a callback procedure to be called when a button's value changes. This callback function is added to each button after creation as the button's XmNvalueChangedCallback. The callback function is called when a button's value changes, and the button number is returned in the client_data field.
The variable portion of the argument list consists of groups of arguments. The first argument in each group is a constant or a string and determines which arguments follow in that group. The last argument in the list must be NULL. The following list describes the possible first arguments in each group of varargs:
This is followed by four additional arguments. The set specifies one
button in the CheckBox and some of its resource values.
The following list describes the additional four arguments, in order.
- The label string, of type XmString
- The mnemonic, of type KeySym. This is ignored in this release.
- The accelerator, of type String. This is ignored in this release.
- The accelerator text, of type XmString. This is ignored in this release.
- This is followed by one additional argument, the value of the resource, of type XtArgVal. The pair specifies a resource and its value for the RowColumn widget.
This is followed by four additional arguments. The set specifies a
resource and its value for the RowColumn widget. A resource type
conversion is performed if necessary. Following are the additional four
arguments, in order:
- The resource name, of type String
- The type of the resource value supplied, of type String
- The resource value (or a pointer to the resource value, depending on the type and size of the value), of type XtArgVal
- The size of the resource value in bytes, of type int
- This is followed by one additional argument of type XtVarArgsList. This argument is a nested list of varargs returned by XtVaCreateArgsList.
For more information on variable-length argument lists, see the X Toolkit Intrinsics documentation.
A number of resources exist specifically for use with this and other simple menu creation routines. For a complete definition of RowColumn and its associated resources, see XmRowColumn(3).
