   5 What's new in 2.1.13
   6 --------------------
   7 Skipped a version number to match what has been released for wxGTK.
   8
   9 Updated wxMVCTree and added a demo for it, also fixed layout on GTK
  10 and some flicker problems.
  11
  12 Added a wrapper class for the Visualization ToolKit (or VTK) in the
  13 wxPython.lib.vtk module.  (http://www.kitware.com/)
  14
  15 Fixed wxTreeCtrl.SetItemImage and GetItemImage to recognise the new
  16 "which" parameter.
  17
  18 Added wxPython.lib.spashscreen from Mike Fletcher.
  19
  20 Added wxPython.lib.filebrowsebutton also from Mike Fletcher.
  21
  22 Renamed wxTreeCtrl.GetParent to GetItemParent to avoid a name clash
  23 with wxWindow.GetParent.
  24
  25 Added wxIntersectRect to compute the intersection of two wxRect's.
  26 It is used like this:
  27
  28    intersect = wxIntersectRect(rect1, rect2)
  29
  30 If r1 and r2 don't intersect then None is returned, otherwise the
  31 rectangle representing the intersection is returned.
  32
  33 Some bug fixes for Clipboard and Drag-n-Drop.
  34
  35 Rotated text!!!  WooHoo!  (See wxDC.DrawRotatedText())
  36
  37 Added a set of Generic Buttons to the library.  These are simple
  38 window classes that look and act like native buttons, but you can have
  39 a bit more control over them.  The bezel width can be set in addition
  40 to colours, fonts, etc.  There is a ToggleButton as well as Bitmap
  41 versions too.  They should also serve as a good example of how to
  42 create your own classes derived from wxControl.
  43
  44 The C++ wxToolBar classes have been redone, and so have the wxPython
  45 wrappers.  There have been slight modifications to some of the methods
  46 but shouldn't impact anybody too much.  I took the opportunity to add
  47 support for setting user data on each toolbar tool.  The new AddTool
  48 methods look like this:
  49
  50         def AddTool(ID,
  51                     bitmap,
  52                     pushedBitmap = wxNullBitmap,
  53                     toggle = FALSE,
  54                     clientData = NULL,
  55                     shortHelpString = "",
  56                     longHelpString = "")
  57
  58         def AddSimpleTool(ID,
  59                           bitmap,
  60                           shortHelpString = "",
  61                           longHelpString = "",
  62                           toggle=FALSE)
  63
  64
  65 There are also coresponding InsertTool and InsertSimpleTool methods
  66 that additionally take an integer position as the first parameter.
  67
  68 Added a wrapper for the new PCX and TIFF ImageHandlers.
  69
  70 wxRect now simulates attributes named left, right, top and bottom.
  71
  72 Removed all non wx stuff from the glcanvas module since DA's PyOpenGL
  73 is better and compatible with the wxGLCanvas.  You can get it at
  74 http://starship.python.net:9673/crew/da/Code/PyOpenGL.
  75
  76 Added some missing EVT_ functions.
  77
  78 Added Dirk Holtwic's editor classes to the wxPython.lib.editor
  79 package.
  80
  81 Changed all the "LIST" parameter names to "choices" to match the docs.
  82
  83 More fixes for the wxFloatBar, and it now works on wxGTK even better
  84 than wxMSW!  (The feat is accomplished by using the wxTB_DOCKABLE
  85 style flag instead of trying to float it ourselves.)
  86
  87
  88
  89
  90 What's new in 2.1.11
  91 --------------------
  92 Skipped a few version numbers so wxMSW, wxGTK and wxPython are all
  93 syncronized.
  94
  95 wxImage.SetData now makes a copy of the image data before giving it to
  96 wxImage.  I mistakenly thought that wxImage would copy the data
  97 itself.
  98
  99 Fixed wxMSW's notebook so the pages get their size set as they are
 100 being added.  This should remove the need for our
 101 wxNotebook.ResizeChildren hack.
 102
 103 wxPanels now support AutoLayout, and wxNotebooks and wxSplitterWindows
 104 no longer tell their children to Layout() themselves.  This will
 105 probably only effect you if you have a wxWindow with AutoLayout inside
 106 a notebook or splitter.  If so, either change it to a wxPanel or add
 107 an EVT_SIZE handler that calls Layout().
 108
 109 Fixed deadlock problem that happened when using threads.
 110
 111 Added new HTML printing classes.
 112
 113 Added wxWindow.GetHandle
 114
 115 Apparently wxMouseEvent.Position has been depreciated in wxWindows as
 116 it is no longer available by default.  You can use GetPositionTuple
 117 (returning a tuple with x,y) instead, or GetPosition (returning a
 118 wxPoint.)
 119
 120 Added wxPostEvent function that allows events to be posted and then
 121 processed later.  This is a thread-safe way to interact with the GUI
 122 thread from other threads.
 123
 124 Added Clipboard and Drag-and-Drop classes.
 125
 126 Added wxFontEnumerator.
 127
 128 Many updates to wxMenu, wxMenuBar.
 129
 130 wxPyEvent and wxPyCommandEvent derived classes now give you the actual
 131 Python object in the event handler instead of a new shadow.
 132
 133 Added a Calendar widget from Lorne White to the library.
 134
 135 Made some fixes to the wxFloatbar.  It still has some troubles on
 136 wxGTK...
 137
 138 Added an MVC tree control from Bryn Keller to the library.
 139
 140
 141
 142
 143 What's new in 2.1.5
 144 -------------------
 145 This is a quick bug-fix release to take care of a few nasties that
 146 crept in at the last minute before 2.1.4 was called done.  No new
 147 major features.
 148
 149
 150
 151 What's new in 2.1.4
 152 --------------------
 153
 154 This release is NOT syncronized with a snapshot release of wxGTK or
 155 wxMSW.  For MSW this isn't much of a problem since you can get the
 156 binaries from the web site.  For other platforms you'll have to build
 157 wxGTK from CVS.  (See http://web.ukonline.co.uk/julian.smart/wxwin/cvs.htm)
 158 To get the same set of sources from CVS that I used, checkout using
 159 the wxPy-2-1-4 tag.
 160
 161 Now back to what's new...
 162
 163 Much more support for event-less callbacks and add-on modules.
 164
 165 Created add-on module with wxOGL classes.
 166
 167 Added wxWindow.GetChildren().  Be careful of this.  It returns a *copy*
 168 of the list of the window's children.  While you are using the list if
 169 anything changes in the real list (a child is deleted, etc.) then the
 170 list you are holding will suddenly have window references to garbage
 171 memory and your app will likely crash.  But if you are careful it works
 172 great!
 173
 174 Added a bunch of new and missing methods to wxTreeCrtl.  The
 175 SortChildren method is now supported, but currently only for the
 176 default sort order.
 177
 178 Added typemaps for wxSize, wxPoint, wxRealPoint, and wxRect that allow
 179 either the actual objects or Python sequence values to be used.  For
 180 example, the following are equivallent:
 181
 182     win = wxWindow(parent, size = wxSize(100, 100))
 183     win = wxWindow(parent, size = (100, 100))
 184
 185 Super-charged the wxHtml module.  You can now create your own tag
 186 handlers and also have access to the parser and cell classes.  There
 187 is a tag handler in the library at wxPython.lib.wxpTag that
 188 understands the WXP tag and is able to place wxPython windows on HTML
 189 pages.  See the demo for an example.
 190
 191 A bunch of the methods of wxMenuBar were previously ifdef'd out for
 192 wxGTK.  Added them back in since the methods exist now.
 193
 194 Wrapped the wxHtmlHelpController and related classes.
 195
 196 Wrapped the C++ versions of wxSizer and friends.  The Python-only
 197 versions are still in the library, but depreciated.  (You will get a
 198 warning message if you try to use them, but the warning can be
 199 disabled.) The usage of the C++ versions is slightly different, and
 200 the functionality of wxBorderSizer is now part of wxBoxSizer.  I have
 201 added a few methods to wxSizer to try and make the transition as
 202 smooth as possible, I combined all Add methods into a single method
 203 that handles all cases, added an AddMany method, etc.  One step I did
 204 not take was to make the default value of flag in the Add method be
 205 wxGROW.  This would have made it more backward compatible, but less
 206 portable to and from wxWin C++ code.  Please see the docs and demo for
 207 further details.
 208
 209 Added wxPyEvent and wxPyCommandEvent classes, derived from wxEvent and
 210 wxCommandEvent.  Each of them has SetPyData and GetPyData methods that
 211 accept or return a single Python object.  You can use these classes
 212 directly or derive from them to create your own types of event objects
 213 that can pass through the wxWindows event system without loosing their
 214 Python parts (as long as they are stored with SetPyData.)  Stay tuned
 215 for more info and examples in future releases.
 216
 217 Added wxPython.lib.grids as an example of how to derive a new sizer
 218 from the C++ sizers.  In this module you will find wxGridSizer and
 219 wxFlexGridSizer.  wxGridSizer arrainges its items in a grid in which
 220 all the widths and heights are the same.  wxFlexgridSizer allows
 221 different widths and heights, and you can also specify rows and/or
 222 columns that are growable.  See the demo for a couple examples for how
 223 to use them.
 224
 225 Added the wxValidator class, and created a class named wxPyValidator
 226 that should be used for the base class of any Python validators.  See
 227 the demo for an example.  Please note that you MUST implement a Clone
 228 method in your validator classes because of the way some things work
 229 in the underlying C++ library.  I did not add wxTextValidator because
 230 of some issues of how it transfers data to and from a wxString, which
 231 in wxPython is automatically translated to and from Python strings, so
 232 there would never be a concrete wxString that would hang around long
 233 enough for the validator to do its job.  On the other hand, it should
 234 be real easy to duplicate the functionality of wxTextValidator in a
 235 pure Python class derived from wxPyValidator.
 236
 237 I've finally added a feature that has been on my list for close to two
 238 years!  Ever wondered what that zero is for when you create your app
 239 object?  Well now you can leave it out or explicitly set it to a true
 240 value.  This value now controls what is to be done with sys.stdout and
 241 sys.stderr.  A false value leaves them alone, and a true value sets
 242 them to an instance of wxPyOnDemandOutputWindow.  (On windows the
 243 default is true, on unix platforms the default is false.)  This class
 244 creates a frame containing a wxTextCtrl as soon as anything is written
 245 to sys.stdout or sys.stderr.  If you close the window it will come
 246 back again the next time something is written.  (You can call
 247 app.RestoreStdio to turn this off.)  If you would rather that the stdio be
 248 redirected to a file, you can provide a second parameter to your app
 249 object's constructor that is a filename.  If you want to use your own
 250 class instead of wxPyOnDemandOutputWindow you can either implement
 251 RedirectStdio() in you app class or change the value of
 252 wxApp.outputWindowClass like this:
 253
 254     class MyApp(wxApp):
 255         outputWindowClass = MyClass
 256
 257         def OnInit(self):
 258             frame = MyFrame()
 259             self.SetTopWindow(frame)
 260             return true
 261
 262 Please see the implementation of wxPyOnDemandOutputWindow and wxApp in
 263 wx.py for more details.  A few words of caution:  if you are running
 264 your app in a debugger, changing sys.stdout and sys.stderr is likely
 265 to really screw things up.
 266
 267 Added wxCaret.  Unfortunately it's author has still not documented it
 268 in the wxWindows docs...
 269
 270 Some new 3rd party contributions in wxPython.lib.  PyShell, in
 271 shell.py is an interesting implementaion of an interactive Python
 272 shell in wxWindows.  floatbar.py has a class derived from wxToolBar
 273 that can sense mouse drags and then reparent itself into another
 274 frame. Moving the new frame close to where it came from puts the tool
 275 bar back into the original parent.  (Unfortunately there is currently
 276 a bug in wxGTK's wxFrame.SetToolBar so the FloatBar has some
 277 problems...)
 278
 279
 280
 281
 282 What's new in 2.1b3
 283 --------------------
 284
 285 This release is syncronized with release 2.1 snapshot 9 of wxWindows.
 286
 287 Switched to using SWIG from CVS (see http://swig.cs.uchicago.edu/cvs.html)
 288 for some of the new features and such.  Also they have encorporated my
 289 patches so there is really no reason to stick with the current (very
 290 old) release...  This version of SWIG gives the following new
 291 features:
 292
 293     1. Keyword arguments.  You no longer have to specify all the
 294        parameters with defaults to a method just to specify a
 295        non-default value on the end.  You can now do this instead:
 296
 297           win = wxWindow(parent, -1, style = mystyle)
 298
 299     2. There is now an an equivalence between Python's None and C++'s
 300        NULL.  This means that any methods that might return NULL will
 301        now return None and you can use none where wxWindows might be
 302        expecting NULL.  This makes things much more snake-ish.
 303
 304
 305 There is a new build system based on a new Python program instead of
 306 raw makefiles.  Now wxPython builds are virtually the same on MSW or
 307 Unix systems.  See the end of this file for new build instructions and
 308 see distrib/build.py for more details.
 309
 310 wxDC.Bilt now includes the useMask parameter, and has been split into
 311 two different versions.  wxDC.BlitXY is like what was there before and
 312 takes raw coordinants and sizes, and the new wxDC.Blit is for the new
 313 interface using wxPoints and a wxSize.
 314
 315
 316
 317
 318
 319 What's new in 2.1b2
 320 --------------------
 321
 322 Added the missing wxWindow.GetUpdateRegion() method.
 323
 324 Made a new change in SWIG (update your patches everybody) that
 325 provides a fix for global shadow objects that get an exception in
 326 their __del__ when their extension module has already been deleted.
 327 It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
 328 line 496 if you want to do it by hand.
 329
 330 It is now possible to run through MainLoop more than once in any one
 331 process.  The cleanup that used to happen as MainLoop completed (and
 332 prevented it from running again) has been delayed until the wxc module
 333 is being unloaded by Python.
 334
 335 I fixed a bunch of stuff in the C++ version of wxGrid so it wouldn't
 336 make wxPython look bad.
 337
 338 wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
 339 wxWindow.PopupMenuXY to be consistent with some other methods.
 340
 341 Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.
 342
 343 You can now provide your own app.MainLoop method.  See
 344 wxPython/demo/demoMainLoop.py for an example and some explaination.
 345
 346 Got the in-place-edit for the wxTreeCtrl fixed and added some demo
 347 code to show how to use it.
 348
 349 Put the wxIcon constructor back in for GTK as it now has one that
 350 matches MSW's.
 351
 352 Added wxGrid.GetCells
 353
 354 Added wxSystemSettings static methods as functions with names like
 355 wxSystemSettings_GetSystemColour.
 356
 357 Removed wxPyMenu since using menu callbacks have been depreciated in
 358 wxWindows.  Use wxMenu and events instead.
 359
 360 Added alternate wxBitmap constructor (for MSW only) as
 361       wxBitmapFromData(data, type, width, height, depth = 1)
 362
 363 Added a helper function named wxPyTypeCast that can convert shadow
 364 objects of one type into shadow objects of another type.  (Like doing
 365 a down-cast.)  See the implementation in wx.py for some docs.
 366
 367 Fixed wxImage GetData and SetData to properly use String objects for
 368 data transfer.
 369
 370 Added access methods to wxGridEvent.
 371
 372 New Makefile/Setup files supporting multiple dynamic extension modules
 373 for unix systems.
 374
 375 Fixes for the wxGLCanvas demo to work around a strange bug in gtk.
 376
 377 SWIG support routines now compiled separately instead of being bundled
 378 in wx.cpp.
 379
 380
 381
 382
 383
 384 What's new in 2.1b1
 385 --------------------
 386 Fixed wxComboBox.SetSelection so that it actually sets the selected
 387 item.  (Actually just removed it from wxPython and let it default to
 388 wxChoice.SetSelection which was already doing the right thing.)
 389
 390 Added the Printing Framework.
 391
 392 Switched back to using the wxWindows DLL for the pre-built Win32
 393 version.  The problem was needing to reinitialize static class info
 394 data after loading each extension module.
 395
 396 Lots of little tweaks and additions to reflect changes to various
 397 wxWindows classes.
 398
 399 Fixed a bug with attaching objects to tree items.  Actually was a
 400 symptom of a larger problem with not obtaining the interpreter lock
 401 when doing any Py_DECREFs.
 402
 403 wxSizer and friends.  Sizers are layout tools that manage a colection
 404 of windows and sizers.  Different types of sizers apply different
 405 types of layout algorithms.  You saw it here first!  These classes are
 406 not even in the wxWindows C++ library yet!
 407
 408
 409
 410 What's new in 2.0b9
 411 -------------------
 412 Bug fix for ListCtrl in test4.py (Was a missing file...  DSM!)
 413
 414 Bug fix for occassional GPF on Win32 systems upon termination of a
 415 wxPython application.
 416
 417 Added wxListBox.GetSelections returning selections as a Tuple.
 418
 419 Added a wxTreeItemData that is able to hold any Python object and be
 420 associated with items in a wxTreeCtrl.  Added test pytree.py to show
 421 this feature off.
 422
 423 Added wxSafeYield function.
 424
 425 OpenGL Canvas can be optionally compiled in to wxPython.
 426
 427 Awesome new Demo Framework for showing off wxPython and for learning
 428 how it all works.
 429
 430 The pre-built Win32 version is no longer distributing the wxWindows
 431 DLL.  It is statically linked with the wxWindows library instead.
 432
 433 Added a couple missing items from the docs.
 434
 435 Added wxImage, wxImageHandler, wxPNGHandler, wxJPEGHandler,
 436 wxGIFHandler and wxBMPHandler.
 437
 438 Added new methods to wxTextCtrl.
 439
 440 Fixed some problems with how SWIG was wrapping some wxTreeCtrl
 441 methods.
 442
 443
 444
 445 What's new in 2.0b8
 446 -------------------
 447 Support for using Python threads in wxPython apps.
 448
 449 Several missing methods from various classes.
 450
 451 Various bug fixes.
 452
 453
 454
 455 What's new in 2.0b7
 456 -------------------
 457 Added DLG_PNT and DLG_SZE convienience methods to wxWindow class.
 458
 459 Added missing constructor and other methods for wxMenuItem.
 460
 461
 462
 463 What's new in 2.0b6
 464 -------------------
 465 Just a quickie update to fix the self-installer to be compatible with
 466 Python 1.5.2b2's Registry settings.
 467
 468
 469 What's new in 2.0b5
 470 -------------------
 471 Well obviously the numbering scheme has changed.  I did this to
 472 reflect the fact that this truly is the second major revision of
 473 wxPython, (well the third actually if you count the one I did for
 474 wxWindows 1.68 and then threw away...) and also that it is associated
 475 with the 2.0 version of wxWindows.
 476
 477 I have finally started documenting wxPython.  There are several pages
 478 in the wxWindows documentation tree specifically about wxPython, and I
 479 have added notes within the class references about where and how wxPython
 480 diverges from wxWindows.
 481
 482 Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
 483 window handle.  If you can get the window handle into the python code,
 484 it should just work...  More news on this later.
 485
 486 Added wxImageList, wxToolTip.
 487
 488 Re-enabled wxConfig.DeleteAll() since it is reportedly fixed for the
 489 wxRegConfig class.
 490
 491 As usual, some bug fixes, tweaks, etc.
 492
 493
 494
 495 What's new in 0.5.3
 496 -------------------
 497 Added wxSashWindow, wxSashEvent, wxLayoutAlgorithm, etc.
 498
 499 Various cleanup, tweaks, minor additions, etc. to maintain
 500 compatibility with the current wxWindows.
 501
 502
 503
 504 What's new in 0.5.0
 505 -------------------
 506 Changed the import semantics from "from wxPython import *" to "from
 507 wxPython.wx import *"  This is for people who are worried about
 508 namespace pollution, they can use "from wxPython import wx" and then
 509 prefix all the wxPython identifiers with "wx."
 510
 511 Added wxTaskbarIcon for wxMSW.
 512
 513 Made the events work for wxGrid.
 514
 515 Added wxConfig.
 516
 517 Added wxMiniFrame for wxGTK.
 518
 519 Changed many of the args and return values that were pointers to gdi
 520 objects to references to reflect changes in the wxWindows API.
 521
 522 Other assorted fixes and additions.
 523
 524
 525
 526
 527 What's new in 0.4.2
 528 -------------------
 529
 530 wxPython on wxGTK works!!!  Both dynamic and static on Linux and
 531 static on Solaris have been tested.  Many thanks go to Harm
 532 <H.v.d.Heijden@phys.tue.nl> for his astute detective work on tracking
 533 down a nasty DECREF bug.  Okay so I have to confess that it was just a
 534 DSM (Dumb Stupid Mistake) on my part but it was nasty none the less
 535 because the behavior was so different on different platforms.
 536
 537 The dynamicly loaded module on Solaris is still segfaulting, so it
 538 must have been a different issue all along...
 539
 540
 541
 542 What's New in 0.4
 543 -----------------
 544
 545 1. Worked on wxGTK compatibility.  It is partially working.  On a
 546 Solaris/Sparc box wxPython is working but only when it is statically
 547 linked with the Python interpreter.  When built as a dyamically loaded
 548 extension module, things start acting weirdly and it soon seg-faults.
