13 | About pens, brushes, and the autoSetting flag: | |
14 | ||
15 | Under X, pens and brushes control some of the same X drawing parameters. | |
16 | Therefore, it is impossible to independently maintain the current pen and the | |
17 | current brush. Also, some settings depend on the current logical function. The | |
18 | m_currentFill, etc. instance variables remember state across the brush and | |
19 | pen. | |
20 | ||
21 | Since pens are used more than brushes, the 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 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. | |
