In the following, "frame style" is a complete style of one frame border,
|
|
i.e. the double line at the left side of the frame. A "line" is always a
|
|
trivial single line, i.e. the first line of a double frame style.
|
|
|
|
The following states of the members of this struct are valid:
|
|
|
|
mnPrim mnDist mnSecn frame style
|
|
-------------------------------------------------
|
|
0 0 0 invisible
|
|
>0 0 0 single
|
|
>0 >0 >0 double
|
|
|
|
The behaviour of the member functions for other states is not defined.
|
|
|
|
Per definition the primary line in double frame styles is:
|
|
- The top line for horizontal frame borders.
|
|
- The left line for vertical frame borders.
|
|
- The bottom-left line for top-left to bottom-right diagonal frame borders.
|
|
- The top-left line for bottom-left to top-right diagonal frame borders.
|
|
|
|
The following picture shows the upper end of a vertical double frame
|
|
border.
