SwamiControlFuncDestroy ()

void                (*SwamiControlFuncDestroy)          (SwamiControlFunc *control);

A function to call when the function control is destroyed or when the function callbacks are changed. This function should handle all cleanup for the callback functions. This function is called with control multi-thread write locked.

SwamiControlFunc

typedef struct _SwamiControlFunc SwamiControlFunc;

SWAMI_CONTROL_FUNC_DATA()

#define SWAMI_CONTROL_FUNC_DATA(ctrl)  (SWAMI_CONTROL_FUNC (ctrl)->user_data)

swami_control_func_new ()

SwamiControlFunc *  swami_control_func_new              (void);

Create a new function callback control. Function controls are useful for easily creating custom controls using callback functions.

swami_control_func_assign_funcs ()

void                swami_control_func_assign_funcs     (SwamiControlFunc *ctrlfunc,
                                                         SwamiControlGetValueFunc get_func,
                                                         SwamiControlSetValueFunc set_func,
                                                         SwamiControlFuncDestroy destroy_func,
                                                         gpointer user_data);

Assigns callback functions to a Swami function control object. These callback functions should handle the getting and setting of the control's value. The value passed to these callback functions is initialized to the type of the control's parameter spec and this type should not be changed. The destroy_func callback is called when the control is destroyed or when the callback functions are changed and should do any needed cleanup. The control is not locked for any of these callbacks and so must be done in the callback if there are any thread sensitive operations.
