由于作者习惯使用Qt，习惯了其框架下的水平和垂直布局。但在使用MFC时，却发现并没有十分好用的布局框架，检索了部分资料，发现要么不提供源码，要么方案不理想。搜索了很多资料，最终发现一个可用方案，记录在此。
一、背景
本方案主要参考如下链接：Layout Manager for Dialogs, Formviews, DialogBars and PropertyPages - CodeProject
其布局效果图如下：
二、基类源码

//
// HISTORY:
// 1998/05/1 Initial Release
// 1998/05/13 Added ability to have a Pane with a control
// 1998/05/13 Added better support for TabControls
// 1998/05/14 automatically set Icon to IDR_MAINFRAME
// 1998/05/19 no flicker on restoring position in OnInitialUpdate
// Changed procedure for load/save, see constructor
// 1998/10/02 Added support for Maximum (tracking) size
// 1998/10/02 Much improved handling regarding RELATIVE/GREEDY
// /w critical minimum size
// 1998/10/02 turn on/off gripper at lower right corner
// 1998/10/05 Support for user defined minimum size for items
// (was hardcoded 5 before)
// 1998/10/07 Fix for FormViews
// 1998/10/31 Support for SECDialogBar/CDialogBar
// 1998/10/31 simplified interface
// 1998/10/31 Advanced positioning options
// 1998/10/31 Added paneNull for empty Pane (former: NULL)
// 1998/11/20 Swapped ETSLayoutDialog constructor parameters
// 1998/11/20 Added Pane::addItemSpaceBetween
// [Leo Zelevinsky]
// 1998/11/24 Added fixup for greedy panes
// 1998/11/24 addItemSpaceBetween now subtracts 2*nDefaultBorder
// 1998/11/24 addGrowing() added as a shortcut for a paneNull
// 1998/11/24 simplified interface: no more PaneBase:: / Pane::
// needed
// 1998/11/24 added FILL_* Modes
// 1998/11/24 improved maximum size handling for greedy panes
// 1998/11/25 Fixup of greedy panes caused infinite loop in some
// cases
// 1999/01/07 addItemSpaceLike() added
// 1999/04/03 Fixed ETSLayoutFormView memory leak
// 1999/04/07 Fixed ALIGN_xCENTER
// 1999/04/08 New simple stream-interface added
// 1999/04/09 Added support for an empty Status-Bar for resizing
// instead of a gripper in the lower right corner
// [Andreas Kapust]
// 1999/04/11 New code for much less flickering, OnEraseBkgnd()
// overidden for this task
// 1999/05/12 Split Layout code into understandable pieces and adding
// a lot of comments
// 1999/06/20 ABSOLUTE_X + ALIGN_FILL_X expands item if there is any
// left space (after all Abs/Rel/Greedy processing is done)
// 1999/10/06 Changed Load() and Save() to use WINDOWPLACEMENT
// [Keith Bussell]
// 1999/11/18 Added possibility to add panes of the same orientation
// to another pane. This merges both panes in one big
// pane with the same orientation
// 1999/11/18 Added support for BCGDialogBar (only with BCG > 4.52!)
// 1999/11/25 Addes support for PropertyPages/Sheets. Uses some code
// of a code submission from Anreas Kapust
// 1999/11/25 Renamed classes to ETSLayoutXXX
// 1999/11/25 Use CreateRoot() and Root() instead of m_pRootPane in
// derived class.
// 1999/11/26 Added autopointer support. No need to use normal pointers
// when defining layout anymore. Changed m_pRootPane to
// m_RootPane
// 1999/11/26 Bug in Fixup Greedy II with multiple GREEDY panes and one
// of them min/max limited
// 1999/11/28 Fixed PaneTab::getConstrainVert() for ABSOLUTE_VERT
// 1999/11/28 Fixed itemFixed()
// 1999/11/28 Changed DWORD modeResize Arguments to layModeResize for
// better type safety. Added typesafe operator|
// 1999/12/04 Don't reposition window in UpdateLayout if it's a child
// (as a child Dialog or PropertyPage)
// 1999/12/04 Erase Backgroung with GCL_HBRBACKGROUND (if available)
// 1999/12/04 itemSpaceXXX() adds a NORESIZE item instead of ABSOLUTE_XXX
// this will fix unwanted growing in secondary direction
//
// Version: 1.0 [1999/12/04] Initial Article on CodeProject
//
// 1999/12/10 Erase Backgroung within TabCtrl was 'fixed' badly. Reverted to
// old working code
// 2000/02/02 When the Dialog is child of a View the class works correctly
// now [Didier BULTIAUW]
// 2000/02/15 Combo-Boxes were not working correctly (in all modes!)
// 2000/02/17 aligned SpinButton Controls (with buddy) now handled
// automatically
// !! do not add such a control to the layout !! it is always
// reattached to its buddy.
// 2000/02/17 changed some cotrol class names to the defined constants
//
// Version: 1.1 [2000/02/17]
//
// 2000/02/25 Fixed auto alignment of SpinButton Controls to only affect
// visible ones
// 2000/02/27 Put all the classes into the namespace 'ETSLayout'
// 2000/03/07 Fixed growing Dialog after minimizing and restoring
// 2000/05/22 Whole Statusbar (Gripper) is not excluded anymore in EraseBkgnd()
// instead only the triangular Gripper is excluded
// 2000/05/31 Fix for PropertySheets with PSH_WIZARDHASFINISH [Th鰉mi]
// 2000/05/31 Fix for UpDown-Controls with EditCtrl Buddy in PropertyPages.
// These were not repositioned every time the page is being show
// until the first resize
// 2000/07/28 Problems with resizing ActiveX Controls fixed [Micheal Chapman]
// 2000/07/28 Some strings were not properly wrapped with _T()
// 2000/08/03 Check for BS_GROUPBOX was not correct as BS_GROUPBOX is more than one Bit
// 2000/08/03 New override AddMainArea added to ETSLayoutPropertySheet in order to
// have a hook for additional controls in a PropertySheet (besides the Tab)
// 2000/08/03 New override AddButtons added to ETSLayoutPropertySheet in order to
// have a hook for additional controls in the bottem pane of a PropertySheet
// 2000/08/03 Removed the need for DECLARE_LAYOUT
//
// Version: 1.2 [2000/08/05]

三、工作原理
3.1 布局尺寸基础定义
enum layResizeMode {
GREEDY = 0, // Will eat up as much as it can
ABSOLUTE_HORZ = 1 << 0, // Horizontal size is absolute
RELATIVE_HORZ = 1 << 1, // Horizontal size in percent
ABSOLUTE_VERT = 1 << 2, // Vertical size is absolute
RELATIVE_VERT = 1 << 3, // Vertical size in percent
NORESIZE = ABSOLUTE_HORZ | ABSOLUTE_VERT,
SIZE_MASK = NORESIZE,
ALIGN_LEFT = 1 << 4, // following only for NORESIZE
ALIGN_RIGHT = 1 << 5,
ALIGN_TOP = 1 << 6,
ALIGN_BOTTOM = 1 << 7,
ALIGN_HCENTER = ALIGN_LEFT | ALIGN_RIGHT,
ALIGN_VCENTER = ALIGN_TOP | ALIGN_BOTTOM,
ALIGN_CENTER = ALIGN_HCENTER | ALIGN_VCENTER,
ALIGN_FILL_HORZ = 1 << 8,
ALIGN_FILL_VERT = 1 << 9,
ALIGN_FILL = ALIGN_FILL_HORZ | ALIGN_FILL_VERT,
/* TRACKER_LEFT = 1 << 10, // not yet. May allow tracking of borders
TRACKER_RIGHT = 1 << 11, // between items in the future
TRACKER_TOP = 1 << 12,
TRACKER_BOTTOM = 1 << 13,
*/
};3.2 基础布局
enum layOrientation {
HORIZONTAL,
VERTICAL
};3.3 实际操作
通过阅读源码及示例，总结一句话：布局由panel和item组成。panel决定水平和垂直布局，item设置自身的尺寸调整（如固定尺寸（NORESIZE），充满剩余空间（GREEDY），百分比拉伸（RELATIVE_HORZ，70）表示水平百分之70的尺寸，（RELATIVE_VERT，20）垂直百分之20的尺寸。下图中的红色表示垂直布局中的panel 蓝色表示水平布局中的panel。
参考如下示例：
CreateRoot(VERTICAL)
<< item ( IDC_NEW_ITEM_STATIC, NORESIZE )
<< ( pane(HORIZONTAL, ABSOLUTE_VERT )
<< item( IDC_NEW_ITEM, GREEDY )
<< item( IDC_ADD_ITEM, NORESIZE )
)
<< item ( IDC_ITEM_LIST_STATIC, NORESIZE )
<< item ( IDC_ITEM_LIST, GREEDY )
<< ( pane(HORIZONTAL, ABSOLUTE_VERT )
<< item( IDOK, RELATIVE_HORZ, 70 )
<< item( IDCANCEL, RELATIVE_HORZ, 30 )
);
UpdateLayout();CreateRoot 返回根布局panel。
panel中可添加item和子panel，从而实现不同方向和尺寸的布局。效果图如下：
有时候我们会需要一些空的占位，以实现靠左或靠右的显示效果，这时我们需要使用itemGrowing，具体示例如下（示例中OK和Cancel会在布局中靠右显示）：
CPane bottomPane = pane( HORIZONTAL, ABSOLUTE_VERT )
<< itemGrowing(HORIZONTAL)
<< item( IDOK, NORESIZE )
<< item( IDCANCEL, NORESIZE );
