Win32 SDK Gui编程系列之–ListView自绘OwnerDraw

ListView自绘OwnerDraw

1.ListView自绘OwnerDraw

正在试错是否使用了列表视图，尽量制作出智能的表格编辑器。本页显示了业主抽签的表格数据(二维数组数据)的显示方法。

显示画面和整个程序如下所示。使用ListView_GetSubItemRect宏的话，就不需要getRect函数了。

当nCol的值为0时得到的区域不是第一列，而是全列即整个行的区域。因为下面的程序是左对齐显示的，所以没有问题，但是要把显示放在中间或改变第1列的背景颜色的话，需要第1列的区域。为此，第1列的右端需要从第2列的左端进行修正。
