LBS_OWNERDRAW...
ListBoxを作成するときに、ウィンドウスタイルを指定していません。これらのメッセージは、ListBox自体ではなく、ListBoxの親ウィンドウにも送信されるため、のWindowProcedure()
代わりにそれらをキャッチする必要がありListBoxProcedure()
ます。WM_MEASUREITEM
そのため、WM_DRAWITEM
メッセージは表示されません。
WM_MEASUREITEM
現在のようにメッセージを破棄するのではなく、メッセージを実装する必要があります。
ウィンドウスタイルのようにビットベースのフラグを組み合わせる場合は、|
演算子の代わりに演算子を使用する必要があります。+
LB_GETTEXT
メッセージまたはDefWindowProc()
機能が正しく使用されていません。
代わりにこれを試してください:
