此为我程序中的一个类,本用于WinCE,但在桌面系统上也同样适用!

使用方法(在WM_INITDIALOG或WM_CREATE消息中加入):

CWindowAnchor::BeginControlBound(hwnd)



手动调整控件位置:

CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP,2,8,4,10));

CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP|WAT_RIGHT,2,20,4,10));

CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP,2,8,40,10));

自动调整控件位置(跟据设计时资源文件中控件的大小及位置):

CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP));

CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP|WAT_RIGHT));



响应WM_SIZE消息:

case WM_SIZE:

return HANDLE_WM_SIZE(hwndDlg,wParam,lParam,CWindowAnchor::OnSize);



响应WM_DESTROY消息:

CWindowAnchor::EndControlBound(hwnd);





代码:
#pragma once
#include <map>

#if defined (_MSC_VER)
    #pragma warning(disable: 4786)
#endif

/*用于WindowAnchorInfo结构的停靠类型*/
typedef enum WindowAnchorType
{
    WAT_TOP=0x0001,
    WAT_LEFT=0x0002,
    WAT_RIGHT=0x0004,
    WAT_BOTTOM=0x0008
};

/*控件定位描述信息*/
typedef struct WindowAnchorInfo{
    DWORD dwAnchor; //WAT_*
    RECT rcOriginalRect; //控件的原始边距,如果为空则自动获取(仅适用于WM_INIT中)
    
    WindowAnchorInfo(DWORD pAnchor=WAT_TOP|WAT_LEFT,LONG pLeft=0,LONG pTop=0,LONG pRight=0,LONG pBottom=0)
    {
        dwAnchor=pAnchor;
        rcOriginalRect.left=pLeft;
        rcOriginalRect.top=pTop;
        rcOriginalRect.right=pRight;
        rcOriginalRect.bottom=pBottom;
    };
};

typedef std::map<HWND,WindowAnchorInfo> ControlHashtable;

typedef struct{
    INT nWidth; //对话框宽度
    INT nHeight; //对话框高度
    INT nMinHeight; //对话框最小高度
    ControlHashtable mapControls; //对话框所有子控件
}WindowAnchorDialog;

/*

static class CWindowAnchor
{
private:
    static BOOL _ReSize(HWND hwndDlg, const WindowAnchorDialog *wad, HWND hwndCtrl, const WindowAnchorInfo *wai);

public:
    /*
     * 开始调整(此调用中会获取当前对话框的大小,如果在设计后要调整对话框大小,请先调用此方法)
     * hwndDlg:对话框句柄
    */
    static BOOL BeginControlBound(HWND hwndDlg);

    /*
     * 结束调整
     * hwndDlg:对话框句柄
    */
    static BOOL EndControlBound(HWND hwndDlg);

    /*
     * 添加一个控件到调整列表
     * hWndInsertAfter:HWND_BOTTOM |HWND_NOTOPMOST | HWND_TOP | HWND_TOPMOST |-2不改变 | Is Hwnd
    */
    static BOOL AddControl(HWND hwndDlg, INT nCtrlID, WindowAnchorInfo *wai, HWND hWndInsertAfter=(HWND)-2);

    /*
     * 调整一个指定控件的大小
    */
    static BOOL ReSize(HWND hwndDlg, HWND hwndCtrl);

    /*
     * 响应WM_SIZE消息
    */
    static BOOL OnSize(HWND hwndDlg, UINT state, int cx, int cy);

    /*相应WM_VSCROLL消息*/
    static BOOL OnVScroll(HWND hwnd, HWND hwndCtl, UINT code, int pos);
};
