博客记录到11天，进度已经15天（多任务）了。因为一个不小心就往前冲，停不下来。进度到一半，感觉接下去才是操作系统的核心。前面都是关于硬件的，没有涉及理论。先把11天记录下来再说。
今天是昨天的延续。在完成叠加处理后可以制作新的窗口。而叠加处理不用修改，只需加个图层就行。主要代码其实跟显示鼠标差不多，如下。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | void make_window8(unsigned char *buf, int xsize, int ysize, char *title) { static char closebtn[14][16] = { "OOOOOOOOOOOOOOO@", "OQQQQQQQQQQQQQ$@", "OQQQQQQQQQQQQQ$@", "OQQQ@@QQQQ@@QQ$@", "OQQQQ@@QQ@@QQQ$@", "OQQQQQ@@@@QQQQ$@", "OQQQQQQ@@QQQQQ$@", "OQQQQQ@@@@QQQQ$@", "OQQQQ@@QQ@@QQQ$@", "OQQQ@@QQQQ@@QQ$@", "OQQQQQQQQQQQQQ$@", "OQQQQQQQQQQQQQ$@", "O$$$$$$$$$$$$$$@", "@@@@@@@@@@@@@@@@" }; int x, y; char c; boxfill8(buf, xsize, COL8_C6C6C6, 0, 0, xsize - 1, 0 ); boxfill8(buf, xsize, COL8_FFFFFF, 1, 1, xsize - 2, 1 ); boxfill8(buf, xsize, COL8_C6C6C6, 0, 0, 0, ysize - 1); boxfill8(buf, xsize, COL8_FFFFFF, 1, 1, 1, ysize - 2); boxfill8(buf, xsize, COL8_848484, xsize - 2, 1, xsize - 2, ysize - 2); boxfill8(buf, xsize, COL8_000000, xsize - 1, 0, xsize - 1, ysize - 1); boxfill8(buf, xsize, COL8_C6C6C6, 2, 2, xsize - 3, ysize - 3); boxfill8(buf, xsize, COL8_000084, 3, 3, xsize - 4, 20 ); boxfill8(buf, xsize, COL8_848484, 1, ysize - 2, xsize - 2, ysize - 2); boxfill8(buf, xsize, COL8_000000, 0, ysize - 1, xsize - 1, ysize - 1); putfont8_asc(buf, xsize, 24, 4, COL8_FFFFFF, title); for (y = 0; y < 14; y++) { for (x = 0; x < 16; x++) { c = closebtn[y][x]; if (c == '@') { c = COL8_000000; } else if (c == '$') { c = COL8_848484; } else if (c == 'Q') { c = COL8_C6C6C6; } else { c = COL8_FFFFFF; } buf[(5 + y) * xsize + (xsize - 21 + x)] = c; } } return; } |
效果如下：居然有一点win98的味道了。
然后作者不满意鼠标移动到图层的闪烁。因此加以优化。闪烁的主要原因是刷新整个上部图层效率不高。作者是用“MAP”的方式，记下屏幕每块区域的所属。这样之后，比如鼠标所在map就不需要刷新了。代码修改比较多，可以看github。
今天内容较少。。。。。
