winapi - Win32 Virtual ListView: Cannot select full row -
yesterday downloaded sdk example virtual listview. code run can't figure out how make listview full row select (it hightlight first column).
here how modify source code create listview:
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 data although followed msdn guide:
lvs_ex_fullrowselect
when item selected, item , subitems highlighted. style available in conjunction lvs_report style.
but listview still refuse select full row. how work?
here full code:
vlistvw.h

}
the lvs_ex_xxx styles extended listview styles, aren't regular window styles. can't specify them in createwindowex call, have set them after window creation using lvm_setextendedlistviewstyle message. example,
sendmessage(hwndlistview, lvm_setextendedlistviewstyle, lvs_ex_fullrowselect, lvs_ex_fullrowselect);
