13 | About pens, brushes, and the m_autoSetting flag: | |
14 | ||
15 | Under X, pens and brushes control some of the same X drawing | |
16 | parameters. Therefore, it is impossible to independently maintain | |
17 | the current pen and the current brush. Also, some settings depend on | |
18 | the current logical function. The m_currentFill, etc. instance | |
19 | variables remember state across the brush and pen. | |
20 | ||
21 | Since pens are used more than brushes, the m_autoSetting flag is used to | |
22 | indicate that a brush was recently used, and SetPen must be called to | |
23 | reinstall the current pen's parameters. If m_autoSetting includes 0x2, then the | |
24 | pens color may need to be set based on XOR. | |
25 | ||
26 | There is, unfortunately, some confusion between setting the current pen/brush | |
27 | and actually installing the brush/pen parameters. Both functionalies are | |
28 | perform by SetPen and SetBrush. C'est la vie. | |
