//
// 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 [Thömmi]
// 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)
