lstview1の実態をBListViewのコンストラクタに位置と名前を渡して作成しているのは他のビューと同じです。違うのは、lstview1をAddChildしていない点です。
sprintf(wk,"List1=%d,List2=",
(int)mainview->lstview1->CurrentSelection(0));
for(int i=0;idx!=-1;i++)
{
char wk1[10];
idx=(int)mainview->lstview2->CurrentSelection(i);
sprintf(wk1,"%d,",idx);
strcat(wk,wk1);
};
mainview->strview->SetText(wk);
まず、最初のsprintfで、lstview1の選択状況とList2の見出しを作成しています。| 圧縮ファイル R5 Intel環境で確認 |
