# lqr\_progress\_set\_init(3)

execude custom code before each rescaling operation

## 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)](/lqr_carver_resize/3.md) 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)](/lqr_progress_set_init_width_message/3.md) and [**lqr\_progress\_set\_init\_height\_message**(3)](/lqr_progress_set_init_height_message/3.md).

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.
