55034339 | 13 | About pens, brushes, and the m_autoSetting flag: |
af0bb3b1 | 14 | |
729be74d MB |
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. | |
af0bb3b1 | 20 | |
55034339 | 21 | Since pens are used more than brushes, the m_autoSetting flag is used to |
af0bb3b1 | 22 | indicate that a brush was recently used, and SetPen must be called to |
55034339 | 23 | reinstall the current pen's parameters. If m_autoSetting includes 0x2, then the |
af0bb3b1 VZ |
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. | |
