VC通用控件自适应屏幕类

2009-04-28 10:01 274 查看
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:

/*

static BOOL BeginControlBound(HWND hwndDlg);

/*

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);

};
