如何使用Windows SDK重绘菜单(弹出菜单的框架边缘)? [英] How to Use Windows SDK redrawing the Menu (The Frame edge of the popupmenu)?

问题描述

大家好，

我正在尝试重新绘制菜单(具有POPUP样式的菜单，右键菜单为右键菜单)，我已经重新编码了以下三则消息:WM_MESUREITEM，WM_INITPOPUP和WM_DRAWITEM，但是最终结果并不令我满意.
上面的三则消息仅涉及菜单项，整个菜单框架看起来非常丑陋，菜单框架尚未重绘，我仍然不知道如何.

在这里，我列出了这三个消息的代码:

 大小写 WM_DRAWITEM:
{
UINT ctlID =(UINT)wParam;
LPDRAWITEMSTRUCT lpDraw =(LPDRAWITEMSTRUCT)lParam;
//  if(ctlID == 0){
HDC hDC = lpDraw-> hDC;

SetBkMode(hDC，TRANSPARENT);
字符 mStr [ 255 ] = { 0  };
HMENU hMenu =(HMENU)lpDraw-> hwndItem;
 int  len = GetMenuString(hMenu，lpDraw-> itemID，mStr， 255 ，MF_BYCOMMAND);
//  HRGN菜单Rgn = lpDraw-> rcItem; 
HBRUSH hBrush = CreateSolidBrush(RGB( 33 ， 82 ， 153 ));
HBRUSH hBrushSel = CreateSolidBrush(RGB( 37 ， 125 ， 194 ));
HBRUSH hBrushFont = CreateSolidBrush(RGB( 206 ， 206 ， 206 ));
HBRUSH hBrushUnSel = CreateSolidBrush(RGB( 27 ， 30 ， 32 ));
HBRUSH hBrushSep = CreateSolidBrush(RGB( 0 ， 0 ， 0 ));

如果(lpDraw-> itemID！=  0 ){
如果(lpDraw-> itemAction& ODA_SELECT)
{
FillRect(hDC，&(lpDraw-> rcItem)，hBrushSel);
如果(lpDraw-> itemState& ODS_GRAYED)
SetTextColor(hDC，RGB( 70 ， 70 ， 70 ))；
 else  SetTextColor(hDC，RGB( 206 ， 206 ， 206 ))；
}
如果(！(((lpDraw-> itemAction& ODA_SELECT)&&(lpDraw-> itemState& ODS_SELECTED))
{
FillRect(hDC，&(lpDraw-> rcItem)，hBrushUnSel);
如果(lpDraw-> itemState& ODS_GRAYED)
SetTextColor(hDC，RGB( 70 ， 70 ， 70 ))；
 else  SetTextColor(hDC，RGB( 206 ， 206 ， 206 ))；
}
}
其他 {
HDC hDCMEM = CreateCompatibleDC(hDC);
HBITMAP hBMP = LoadBitmap(G_hInstance，" );
SelectObject(hDCMEM，hBMP);
StretchBlt(hDC，(lpDraw-> rcItem).left，(lpDraw-> rcItem).top，RWIDTH(lpDraw-> rcItem)，RHEIGHT(lpDraw-> rcItem)，
hDCMem， 1 ， 0 ， 1 ，  4 ，SRCCOPY);
//  FillRect(hDC，&(lpDraw-> rcItem)，hBrushSep); 
DeleteObject(hBMP);
DeleteDC(hDCMEM);

}
TextOut(hDC，(lpDraw-> rcItem).left +  20 ，(lpDraw-> rcItem).top +  4 ，mStr，len)；
DeleteObject(hBrush);
DeleteObject(hBrushSel);
DeleteObject(hBrushFont);
DeleteObject(hBrushUnSel);
DeleteObject(hBrushSep);
返回  0 ;
//  FrameRect(hDC，&(lpDraw-&rc; rcItem)，hBrush); 
// } 
}
 break ;
案例 WM_MEASUREITEM:
{
UINT ctlID =(UINT)wParam; // 控件标识符
LPMEASUREITEMSTRUCT lpItemStruct =(LPMEASUREITEMSTRUCT)lParam;
如果(lpItemStruct-> CtlType == ODT_MENU){
如果( 0  == lpItemStruct-> itemID){
lpItemStruct-> itemWidth =  150 ;
lpItemStruct-> itemHeight =  2 ;
}
其他 {
lpItemStruct-> itemWidth =  150 ;
lpItemStruct-> itemHeight =  20 ;
}
返回  0 ;
}

}
 break ;
案例 WM_INITMENUPOPUP:
{
HMENU hMenu =(HMENU)wParam;
 int  uPos =(UINT)LOWORD(lParam);
BOOL fSystemMenu =(BOOL)HIWORD(lParam);

 int  itemCount = GetMenuItemCount(hMenu);
 for ( int  i =  0 ；我< itemCount; i ++){
HMENU mItem = GetSubMenu(hMenu，i);
UINT mItemID = GetMenuItemID(hMenu，i);
字符 mStr [ 255 ] = { 0  };
GetMenuString(hMenu，i，mStr， 255 ，MF_BYPOSITION);
ModifyMenu(hMenu，i，MF_BYPOSITION | MF_OWNERDRAW，mItemID，(LPCTSTR)mStr);
//  MessageBox(hWnd，mStr，"MENU"，MB_OK); 
}
返回  0 ;
}
中断;

Hope anyone give me a suggestion , thanks !
