NAME

       lqr_progress_set_init - execude custom code before each rescaling operation

SYNOPSIS

       #include <lqr.h>

       LqrRetVal lqr_progress_set_init(LqrProgress* p, LqrProgressFuncInit init_func);

DESCRIPTION

       The function lqr_progress_set_init sets the hook init_func to the LqrProgress object
       pointed to by p.

       The function init_func is of type LqrProgressFuncInit, whose prototype is defined by:

           typedef LqrRetVal (*LqrProgressFuncInit) (const gchar* init_message);

       Each time that the function lqr_carver_resize(3) performs a rescale operation (recall that
       it can perform more than one rescale operation at each call) this function will be called
       first, with a string argument passed through the parameter init_message, which is
       different for horizontal and vertical rescalings.

       The message arguments can be set with the functions lqr_progress_set_init_width_message(3)
       and lqr_progress_set_init_height_message(3).

       The default values for newly created LqrProgress objects are:

       Horizontal:

           "Resizing width..."

       Vertical:

           "Resizing height..."

RETURN VALUE

       The return value follows the Liquid Rescale library signalling system.
