win32 sdk绘制ListBox控件

1》产生：

1. //
2. HWND CreateLB(HWND parentWnd)
3. {
4. HWND hListBox=0;
5. hListBox = CreateWindow("LISTBOX",
6. NULL,
7. WS_CHILD|WS_VSCROLL | WS_TABSTOP | LBS_STANDARD | LBS_OWNERDRAWFIXED | LBS_HASSTRINGS,
8. 230, 20, 60, 80,
9. parentWnd, (HMENU)IDC_LISTBOX,
10. (HINSTANCE) GetWindowLong(parentWnd, GWL_HINSTANCE),
11. NULL);
12. ShowWindow(hListBox,SW_SHOW);
13. SendMessage(hListBox,LB_ADDSTRING ,0,(LPARAM)"你好");
14. SendMessage(hListBox,LB_ADDSTRING ,0,(LPARAM)"我好");
15. SendMessage(hListBox,LB_ADDSTRING ,0,(LPARAM)"他好");
16. //
17. return hListBox;
18. }

2》指定size：

 

1. case WM_MEASUREITEM://ODT_LISTBOX
2. if((UINT) wParam==IDC_LISTBOX)
3. {
4. LPMEASUREITEMSTRUCT lpmis = (LPMEASUREITEMSTRUCT) lParam;
5. lpmis->itemWidth=400;
6. lpmis->itemHeight=22;
7. }
8. break;

3》画：

 

1. case WM_DRAWITEM:
2. if((UINT) wParam==IDC_LISTBOX)
3. {
4. LPDRAWITEMSTRUCT pDI=(LPDRAWITEMSTRUCT) lParam;
5. HBRUSH brsh=CreateSolidBrush(RGB(255-30*pDI->itemID, 128+40*pDI->itemID, 128+40*pDI->itemID));//yellow
6. FillRect(pDI->hDC,&pDI->rcItem,brsh);
7. DeleteObject(brsh);
8. // text
9. SetBkMode(pDI->hDC,TRANSPARENT);
10. char szText[260];
11. SendMessage(m_hListBox,LB_GETTEXT,pDI->itemID,(LPARAM)szText);
12. const DWORD dwStyle = DT_LEFT | DT_SINGLELINE | DT_VCENTER | DT_NOPREFIX | DT_END_ELLIPSIS;
13. DrawText(pDI->hDC, szText, strlen(szText), &pDI->rcItem, dwStyle);
14. }
15. break;
