lqr_progress_set_init — execude custom code before each rescaling operation
#include <lqr.h>
LqrRetVal lqr_progress_set_init( | LqrProgress* p, |
LqrProgressFuncInit init_func); |
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:
"Resizing width..."
"Resizing height..."
LqrRetVal(3), lqr_progress_new(3), lqr_progress_set_update(3), lqr_progress_set_end(3), lqr_progress_set_init_width_message(3), lqr_progress_set_init_height_message(3), lqr_progress_set_end_width_message(3), lqr_progress_set_end_height_message(3), lqr_progress_set_update_step(3), lqr_carver_set_progress(3)
