刷屏函数:
/qt/src/gui/painting/qdrawhelper_p.h的
inline void qt_rectcopy()函数的
::memcpy(d, s, width * sizeof(T))语句。
printf("xhr ---qt_rectcopy/n");
不同的插件有不同的写入函数:
/qt/src/gui/painting/qdrawhelper.cpp的
inline void qt_memfill_template函数的
switch (count & 0x07)
{
case 0: do { *dest++ = c;
case 7: *dest++ = c;
case 6: *dest++ = c;
case 5: *dest++ = c;
case 4: *dest++ = c;
case 3: *dest++ = c;
case 2: *dest++ = c;
case 1: *dest++ = c;
} while (--n > 0)
printf("xhr ---qt_memfill_template_two/n ");
