金山卫士UI原理解析(2)CBkWindow

 

一.CBkWindow

CBkWindow相当于传统win32的窗体类,但并非每个窗体有一句柄,而是把把一个HWND当作一个容器

同时其还包含一个BkWnds，BkWnds是一个单例类，其包含多个CBkWindow

CBkWindow继承自CBkObject

1.共有属性

BKWIN_DECLARE_ATTRIBUTES_BEGIN()BKWIN_STYLE_ATTRIBUTE("class", m_style, TRUE)BKWIN_INT_ATTRIBUTE("id", m_uCmdID, FALSE)//, 0)BKWIN_COLOR_ATTRIBUTE("crbg", m_style.m_crBg, FALSE)BKWIN_COLOR_ATTRIBUTE("crtext", m_style.m_crText, FALSE)BKWIN_FONT_ATTRIBUTE("font", m_style.m_ftText, FALSE)BKWIN_TSTRING_ATTRIBUTE("href", m_strLinkUrl, FALSE)BKWIN_TSTRING_ATTRIBUTE("tip", m_strToolTipText, FALSE)BKWIN_ENUM_ATTRIBUTE("valign", UINT, TRUE)BKWIN_ENUM_VALUE("top", VAlign_Top)BKWIN_ENUM_VALUE("middle", VAlign_Middle)BKWIN_ENUM_VALUE("bottom", VAlign_Bottom)BKWIN_ENUM_END(m_uVAlign)BKWIN_ENUM_ATTRIBUTE("align", UINT, TRUE)BKWIN_ENUM_VALUE("left", Align_Left)BKWIN_ENUM_VALUE("center", Align_Center)BKWIN_ENUM_VALUE("right", Align_Right)BKWIN_ENUM_END(m_uHAlign)BKWIN_CUSTOM_ATTRIBUTE("pos", OnAttributePosChange)BKWIN_INT_ATTRIBUTE("transparent", m_bTransparent, FALSE)//, 0) BKWIN_DECLARE_ATTRIBUTES_END()

2.必要的消息

为重绘和控件定位等做准备

BKWIN_BEGIN_MSG_MAP()MSG_WM_CREATE(OnCreate)MSG_WM_PAINT(OnPaint)MSG_WM_DESTROY(OnDestroy)MSG_WM_WINDOWPOSCHANGED(OnWindowPosChanged)MSG_WM_NCCALCSIZE(OnNcCalcSize)MSG_WM_SHOWWINDOW(OnShowWindow) BKWIN_END_MSG_MAP_BASE()

3.Load方法

其会解析每个xml的节点,并初始化CBkWindow的数据

4.OnPaint

BeforePaint用于获取style的样式

AfterPaint用于恢复原先样式信息.

BkStyle类定义了样式信息

void BeforePaint(CDCHandle &dc, BkDCPaint &BkDC) {HFONT /*hftOld = NULL, */hftDraw = NULL;COLORREF /*crOld = CLR_INVALID, crOldBg = CLR_INVALID, */crDraw = CLR_INVALID;/*int nOldBkMode = OPAQUE;*/BkDC.rcClient = m_rcWindow;BkDC.rcClient.DeflateRect(m_style.m_nMarginX, m_style.m_nMarginY);if (!m_style.m_strSkinName.IsEmpty()){BkDC.bBkModeChanged = TRUE;BkDC.nOldBkMode = dc.SetBkMode(TRANSPARENT);}if (CLR_INVALID != m_style.m_crBg){BkDC.bBgColorChanged = TRUE;BkDC.crOldBg = dc.SetBkColor(m_style.m_crBg);}if (m_style.m_ftText)hftDraw = m_style.m_ftText;if (m_style.m_crText != CLR_INVALID)crDraw = m_style.m_crText;if (IsDisabled(TRUE)/*BkWndState_Disable == (GetState() & BkWndState_Disable)*/){if (m_style.m_crDisabledText != CLR_INVALID)crDraw = m_style.m_crDisabledText;}else if (BkWndState_Hover == (GetState() & BkWndState_Hover)){if (m_style.m_ftHover)hftDraw = m_style.m_ftHover;if (m_style.m_crHoverText != CLR_INVALID)crDraw = m_style.m_crHoverText;}if (hftDraw){BkDC.bFontChanged = TRUE;BkDC.hftOld = dc.SelectFont(hftDraw);}if (crDraw != CLR_INVALID){BkDC.bTextColorChanged = TRUE;BkDC.crOld = dc.SetTextColor(crDraw);} }void AfterPaint(CDCHandle &dc, BkDCPaint &BkDC) {if (BkDC.bFontChanged)dc.SelectFont(BkDC.hftOld);if (BkDC.bTextColorChanged)dc.SetTextColor(BkDC.crOld);if (BkDC.bBkModeChanged)dc.SetBkMode(BkDC.nOldBkMode);if (BkDC.bBgColorChanged)dc.SetBkColor(BkDC.crOldBg); }// Draw inner text default void OnPaint(CDCHandle dc) {BkDCPaint BkDC;BeforePaint(dc, BkDC);dc.DrawText(m_strInnerText, m_strInnerText.GetLength(), BkDC.rcClient, m_style.m_nTextAlign);AfterPaint(dc, BkDC); }

二.BkStyle

同skin一样，也是从xml载入资源

<style> <class name=mainhead skin=mainbghead font=0000 crtext=000000 crbg=FBFCFD/> <class name=mainbody skin=mainbgbody font=0000 crtext=FFFFFF crbg=FBFCFD x-margin=7/> <class name=mainfoot skin=mainbgfoot font=0000 crtext=000000 crbg=FBFCFD x-margin=10 y-margin=1/> <class name=msgboxhead skin=msgboxhead font=0000 crtext=000000 crbg=FBFCFD/> <class name=msgboxbody skin=msgboxbody font=0000 crtext=000000 crbg=FBFCFD/> <class name=msgboxfoot skin=msgboxfoot font=0000 crtext=000000 crbg=FBFCFD/> <class name=dlgbody skin=dlgbody font=0000 crtext=000000 crbg=FBFCFD/> <class name=dlgfoot skin=dlgfoot font=0000 crtext=000000 crbg=FBFCFD/> <class name=linktext font=0002 hoverfont=0002 crtext=3064A5 crhover=FF0000 cursor=hand/> <class name=linktext2 crtext=3064A5 crhover=FF0000 cursor=hand/> <class name=linktext3 font=0002 hoverfont=0002 crtext=0051E5 crhover=FF0000 cursor=hand/> … </style>
