Win32 Virtual ListView:无法选择完整行

时间:2016-02-06 08:07:43

标签: listview winapi virtualization fullrowselect

昨天我下载了一个关于Virtual ListView的SDK示例。代码运行成功,但我无法弄清楚如何使ListView完整行选择(它只是hightlight第一列)。
以下是我修改源代码以创建ListView的方法:

dwStyle = WS_TABSTOP |
    WS_CHILD |
    WS_VISIBLE |
    LVS_AUTOARRANGE |
    LVS_REPORT |
    LVS_OWNERDATA;

hwndListView = CreateWindowEx(LVS_EX_FULLROWSELECT,          // ex style
    WC_LISTVIEW,               // class name - defined in commctrl.h
    TEXT(""),                        // dummy text
    dwStyle,                   // style
    0,                         // x position
    0,                         // y position
    0,                         // width
    0,                         // height
    hwndParent,                // parent
    (HMENU)ID_LISTVIEW,        // ID
    g_hInst,                   // instance
    NULL);                     // no extra data

虽然我遵循了MSDN指南:

  

LVS_EX_FULLROWSELECT
  选择项目时,项目及其全部   子项目突出显示。此样式仅可以结合使用   使用LVS_REPORT样式。

但ListView仍然拒绝选择完整行。如何使它工作?

LVS_EX_xxx样式为extended listview styles,这些样式不是常规窗口样式。您无法在CreateWindowEx调用中指定它们,您必须在使用LVM_SETEXTENDEDLISTVIEWSTYLE消息创建窗口后设置它们。例如,

SendMessage(hwndListView, LVM_SETEXTENDEDLISTVIEWSTYLE,
    LVS_EX_FULLROWSELECT, LVS_EX_FULLROWSELECT);
