Function Documentation

calc_header_width_padding()

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 166 of file window.c.

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

Here is the caller graph for this function:

init_header_padding()

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.
