我用下面代码在主窗口上动态建立了一个listview控件,请问怎么编辑 消息响应函数 来响应listview控件内的鼠标消息?
别用MFC的代码 谢谢。
switch (message)
{
case WM_CREATE: RECT rcl;
INITCOMMONCONTROLSEX icex;
// Ensure that the common control DLL is loaded.
icex.dwSize = sizeof(INITCOMMONCONTROLSEX);
icex.dwICC = ICC_LISTVIEW_CLASSES;
InitCommonControlsEx((LPINITCOMMONCONTROLSEX)&icex);
hwndListView = CreateWindow(
WC_LISTVIEW,
"",
dwStyle,
0,
0,
400,
300,
hwnd,
(HMENU)1001,
(HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE),
NULL);

还要问
在响应消息的时候怎么得到鼠标坐标,或者鼠标点击的 listview控件的 哪行?哪列?
谢谢能具体说下在响应消息的时候怎么得到:鼠标坐标,或者鼠标点击的 listview控件的 哪行?哪列?
=========
这个得去查MSDN了,你自己去查下吧,SDK用这个比较麻烦。
