From cd709fcebc0a8c6c2f529cf4cf9d93402a500d2e Mon Sep 17 00:00:00 2001 From: Vadim Zeitlin Date: Fri, 12 Jul 2013 14:12:44 +0000 Subject: [PATCH] Fix harmless MinGW warning in wxMSW wxListCtrl code. Add an explicit cast to WPARAM because MinGW headers don't do it for us (even though they should). git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@74495 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- src/msw/listctrl.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/msw/listctrl.cpp b/src/msw/listctrl.cpp index 9684bf0e9a..9befc6a955 100644 --- a/src/msw/listctrl.cpp +++ b/src/msw/listctrl.cpp @@ -1339,7 +1339,10 @@ void wxListCtrl::AssignImageList(wxImageList *imageList, int which) wxSize wxListCtrl::MSWGetBestViewRect(int x, int y) const { - const DWORD rc = ListView_ApproximateViewRect(GetHwnd(), x, y, -1); + // The cast is necessary to suppress a MinGW warning due to a missing cast + // to WPARAM in the definition of ListView_ApproximateViewRect() in its + // own headers (this was the case up to at least MinGW 4.8). + const DWORD rc = ListView_ApproximateViewRect(GetHwnd(), x, y, (WPARAM)-1); wxSize size(LOWORD(rc), HIWORD(rc)); -- 2.50.0
