27 | | Class computing border widths shared between Line style listbox and the |
28 | | SvxBorderLine implementation. |
29 | | |
30 | | This class doesn't know anything about units: it all depends on the different |
31 | | values set. A border is composed of 2 lines separated by a gap. The computed |
32 | | widths are the ones of each line and the gap and they can either be fix or vary. |
33 | | |
34 | | The #m_nflags member will define which widths will vary (value 0 means that all |
35 | | widths are fixed). The available flags are: |
36 | | - CHANGE_LINE1 |
37 | | - CHANGE_LINE2 |
38 | | - CHANGE_DIST |
39 | | |
40 | | For each line, the rate member is used as a multiplication factor is the width |
41 | | isn't fixed. Otherwise it is the width in the unit expected by the client code. |
