VC通用控件自适应屏幕类

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:
    
/*

     * 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);
};
