Function Documentation

static void calc_header_width_padding	(	int	idx,
		const char *	header,
		bool	calc_max
	)

static

Calculate the width needed for the compose labels.

Parameters

idx	Store the result at this index of HeaderPadding
header	Header string
calc_max	If true, calculate the maximum width

Definition at line 209 of file compose.c.

 {
   int width;
 
   HeaderPadding[idx] = mutt_str_strlen(header);
   width = mutt_strwidth(header);
   if (calc_max && (MaxHeaderWidth < width))
     MaxHeaderWidth = width;
   HeaderPadding[idx] -= width;
 }

Here is the call graph for this function:

Here is the caller graph for this function:

static void init_header_padding ( void )

static

Calculate how much padding the compose table will need.

The padding needed for each header is strlen() + max_width - strwidth().

calc_header_width_padding sets each entry in HeaderPadding to strlen - width. Then, afterwards, we go through and add max_width to each entry.
