   5 What's new in 2.1.12
   6 --------------------
   7 Updated wxMVCTree and added a demo for it, also fixed layout on GTK
   8 and some flicker problems.
   9
  10 Added a wrapper class for the Visualization ToolKit (or VTK) in the
  11 wxPython.lib.vtk module.  (http://www.kitware.com/)
  12
  13 Fixed wxTreeCtrl.SetItemImage and GetItemImage to recognise the new
  14 "which" parameter.
  15
  16 Added wxPython.lib.spashscreen from Mike Fletcher.
  17
  18 Added wxPython.lib.filebrowsebutton also from Mike Fletcher.
  19
  20 Renamed wxTreeCtrl.GetParent to GetItemParent to avoid a name clash
  21 with wxWindow.GetParent.
  22
  23 Added wxIntersectRect to compute the intersection of two wxRect's.
  24 It is used like this:
  25
  26    intersect = wxIntersectRect(rect1, rect2)
  27
  28 If r1 and r2 don't intersect then None is returned, otherwise the
  29 rectangle representing the intersection is returned.
  30
  31 Some bug fixes for Clipboard and Drag-n-Drop.
  32
  33 Rotated text!!!  WooHoo!  (See wxDC.DrawRotatedText())
  34
  35 Added a set of Generic Buttons to the library.  These are simple
  36 window classes that look and act like native buttons, but you can have
  37 a bit more control over them.  The bezel width can be set in addition
  38 to colours, fonts, etc.  There is a ToggleButton as well as Bitmap
  39 versions too.
  40
  41 The C++ wxToolBar classes have been redone, and so have the wxPython
  42 wrappers.  There have been slight modifications to some of the methods
  43 but shouldn't impact anybody too much.  I took the opportunity to add
  44 support for setting user data on each toolbar tool.  The new AddTool
  45 methods look like this:
  46
  47         def AddTool(ID,
  48                     bitmap,
  49                     pushedBitmap = wxNullBitmap,
  50                     toggle = FALSE,
  51                     clientData = NULL,
  52                     shortHelpString = "",
  53                     longHelpString = "")
  54
  55         def AddSimpleTool(ID,
  56                           bitmap,
  57                           shortHelpString = "",
  58                           longHelpString = "",
  59                           toggle=FALSE)
  60
  61
  62 There are also coresponding InsertTool and InsertSimpleTool methods
  63 that additionally take an integer position as the first parameter.
  64
  65 Added a wrapper for the PCX and TIFF ImageHandlers.
  66
  67 wxRect now simulates attributes named left, right, top and bottom.
  68
  69
  70
  71
  72
  73
  74 What's new in 2.1.11
  75 --------------------
  76 Skipped a few version numbers so wxMSW, wxGTK and wxPython are all
  77 syncronized.
  78
  79 wxImage.SetData now makes a copy of the image data before giving it to
  80 wxImage.  I mistakenly thought that wxImage would copy the data
  81 itself.
  82
  83 Fixed wxMSW's notebook so the pages get their size set as they are
  84 being added.  This should remove the need for our
  85 wxNotebook.ResizeChildren hack.
  86
  87 wxPanels now support AutoLayout, and wxNotebooks and wxSplitterWindows
  88 no longer tell their children to Layout() themselves.  This will
  89 probably only effect you if you have a wxWindow with AutoLayout inside
  90 a notebook or splitter.  If so, either change it to a wxPanel or add
  91 an EVT_SIZE handler that calls Layout().
  92
  93 Fixed deadlock problem that happened when using threads.
  94
  95 Added new HTML printing classes.
  96
  97 Added wxWindow.GetHandle
  98
  99 Apparently wxMouseEvent.Position has been depreciated in wxWindows as
 100 it is no longer available by default.  You can use GetPositionTuple
 101 (returning a tuple with x,y) instead, or GetPosition (returning a
 102 wxPoint.)
 103
 104 Added wxPostEvent function that allows events to be posted and then
 105 processed later.  This is a thread-safe way to interact with the GUI
 106 thread from other threads.
 107
 108 Added Clipboard and Drag-and-Drop classes.
 109
 110 Added wxFontEnumerator.
 111
 112 Many updates to wxMenu, wxMenuBar.
 113
 114 wxPyEvent and wxPyCommandEvent derived classes now give you the actual
 115 Python object in the event handler instead of a new shadow.
 116
 117 Added a Calendar widget from Lorne White to the library.
 118
 119 Made some fixes to the wxFloatbar.  It still has some troubles on
 120 wxGTK...
 121
 122 Added an MVC tree control from Bryn Keller to the library.
 123
 124
 125
 126
 127 What's new in 2.1.5
 128 -------------------
 129 This is a quick bug-fix release to take care of a few nasties that
 130 crept in at the last minute before 2.1.4 was called done.  No new
 131 major features.
 132
 133
 134
 135 What's new in 2.1.4
 136 --------------------
 137
 138 This release is NOT syncronized with a snapshot release of wxGTK or
 139 wxMSW.  For MSW this isn't much of a problem since you can get the
 140 binaries from the web site.  For other platforms you'll have to build
 141 wxGTK from CVS.  (See http://web.ukonline.co.uk/julian.smart/wxwin/cvs.htm)
 142 To get the same set of sources from CVS that I used, checkout using
 143 the wxPy-2-1-4 tag.
 144
 145 Now back to what's new...
 146
 147 Much more support for event-less callbacks and add-on modules.
 148
 149 Created add-on module with wxOGL classes.
 150
 151 Added wxWindow.GetChildren().  Be careful of this.  It returns a *copy*
 152 of the list of the window's children.  While you are using the list if
 153 anything changes in the real list (a child is deleted, etc.) then the
 154 list you are holding will suddenly have window references to garbage
 155 memory and your app will likely crash.  But if you are careful it works
 156 great!
 157
 158 Added a bunch of new and missing methods to wxTreeCrtl.  The
 159 SortChildren method is now supported, but currently only for the
 160 default sort order.
 161
 162 Added typemaps for wxSize, wxPoint, wxRealPoint, and wxRect that allow
 163 either the actual objects or Python sequence values to be used.  For
 164 example, the following are equivallent:
 165
 166     win = wxWindow(parent, size = wxSize(100, 100))
 167     win = wxWindow(parent, size = (100, 100))
 168
 169 Super-charged the wxHtml module.  You can now create your own tag
 170 handlers and also have access to the parser and cell classes.  There
 171 is a tag handler in the library at wxPython.lib.wxpTag that
 172 understands the WXP tag and is able to place wxPython windows on HTML
 173 pages.  See the demo for an example.
 174
 175 A bunch of the methods of wxMenuBar were previously ifdef'd out for
 176 wxGTK.  Added them back in since the methods exist now.
 177
 178 Wrapped the wxHtmlHelpController and related classes.
 179
 180 Wrapped the C++ versions of wxSizer and friends.  The Python-only
 181 versions are still in the library, but depreciated.  (You will get a
 182 warning message if you try to use them, but the warning can be
 183 disabled.) The usage of the C++ versions is slightly different, and
 184 the functionality of wxBorderSizer is now part of wxBoxSizer.  I have
 185 added a few methods to wxSizer to try and make the transition as
 186 smooth as possible, I combined all Add methods into a single method
 187 that handles all cases, added an AddMany method, etc.  One step I did
 188 not take was to make the default value of flag in the Add method be
 189 wxGROW.  This would have made it more backward compatible, but less
 190 portable to and from wxWin C++ code.  Please see the docs and demo for
 191 further details.
 192
 193 Added wxPyEvent and wxPyCommandEvent classes, derived from wxEvent and
 194 wxCommandEvent.  Each of them has SetPyData and GetPyData methods that
 195 accept or return a single Python object.  You can use these classes
 196 directly or derive from them to create your own types of event objects
 197 that can pass through the wxWindows event system without loosing their
 198 Python parts (as long as they are stored with SetPyData.)  Stay tuned
 199 for more info and examples in future releases.
 200
 201 Added wxPython.lib.grids as an example of how to derive a new sizer
 202 from the C++ sizers.  In this module you will find wxGridSizer and
 203 wxFlexGridSizer.  wxGridSizer arrainges its items in a grid in which
 204 all the widths and heights are the same.  wxFlexgridSizer allows
 205 different widths and heights, and you can also specify rows and/or
 206 columns that are growable.  See the demo for a couple examples for how
 207 to use them.
 208
 209 Added the wxValidator class, and created a class named wxPyValidator
 210 that should be used for the base class of any Python validators.  See
 211 the demo for an example.  Please note that you MUST implement a Clone
 212 method in your validator classes because of the way some things work
 213 in the underlying C++ library.  I did not add wxTextValidator because
 214 of some issues of how it transfers data to and from a wxString, which
 215 in wxPython is automatically translated to and from Python strings, so
 216 there would never be a concrete wxString that would hang around long
 217 enough for the validator to do its job.  On the other hand, it should
 218 be real easy to duplicate the functionality of wxTextValidator in a
 219 pure Python class derived from wxPyValidator.
 220
 221 I've finally added a feature that has been on my list for close to two
 222 years!  Ever wondered what that zero is for when you create your app
 223 object?  Well now you can leave it out or explicitly set it to a true
 224 value.  This value now controls what is to be done with sys.stdout and
 225 sys.stderr.  A false value leaves them alone, and a true value sets
 226 them to an instance of wxPyOnDemandOutputWindow.  (On windows the
 227 default is true, on unix platforms the default is false.)  This class
 228 creates a frame containing a wxTextCtrl as soon as anything is written
 229 to sys.stdout or sys.stderr.  If you close the window it will come
 230 back again the next time something is written.  (You can call
 231 app.RestoreStdio to turn this off.)  If you would rather that the stdio be
 232 redirected to a file, you can provide a second parameter to your app
 233 object's constructor that is a filename.  If you want to use your own
 234 class instead of wxPyOnDemandOutputWindow you can either implement
 235 RedirectStdio() in you app class or change the value of
 236 wxApp.outputWindowClass like this:
 237
 238     class MyApp(wxApp):
 239         outputWindowClass = MyClass
 240
 241         def OnInit(self):
 242             frame = MyFrame()
 243             self.SetTopWindow(frame)
 244             return true
 245
 246 Please see the implementation of wxPyOnDemandOutputWindow and wxApp in
 247 wx.py for more details.  A few words of caution:  if you are running
 248 your app in a debugger, changing sys.stdout and sys.stderr is likely
 249 to really screw things up.
 250
 251 Added wxCaret.  Unfortunately it's author has still not documented it
 252 in the wxWindows docs...
 253
 254 Some new 3rd party contributions in wxPython.lib.  PyShell, in
 255 shell.py is an interesting implementaion of an interactive Python
 256 shell in wxWindows.  floatbar.py has a class derived from wxToolBar
 257 that can sense mouse drags and then reparent itself into another
 258 frame. Moving the new frame close to where it came from puts the tool
 259 bar back into the original parent.  (Unfortunately there is currently
 260 a bug in wxGTK's wxFrame.SetToolBar so the FloatBar has some
 261 problems...)
 262
 263
 264
 265
 266 What's new in 2.1b3
 267 --------------------
 268
 269 This release is syncronized with release 2.1 snapshot 9 of wxWindows.
 270
 271 Switched to using SWIG from CVS (see http://swig.cs.uchicago.edu/cvs.html)
 272 for some of the new features and such.  Also they have encorporated my
 273 patches so there is really no reason to stick with the current (very
 274 old) release...  This version of SWIG gives the following new
 275 features:
 276
 277     1. Keyword arguments.  You no longer have to specify all the
 278        parameters with defaults to a method just to specify a
 279        non-default value on the end.  You can now do this instead:
 280
 281           win = wxWindow(parent, -1, style = mystyle)
 282
 283     2. There is now an an equivalence between Python's None and C++'s
 284        NULL.  This means that any methods that might return NULL will
 285        now return None and you can use none where wxWindows might be
 286        expecting NULL.  This makes things much more snake-ish.
 287
 288
 289 There is a new build system based on a new Python program instead of
 290 raw makefiles.  Now wxPython builds are virtually the same on MSW or
 291 Unix systems.  See the end of this file for new build instructions and
 292 see distrib/build.py for more details.
 293
 294 wxDC.Bilt now includes the useMask parameter, and has been split into
 295 two different versions.  wxDC.BlitXY is like what was there before and
 296 takes raw coordinants and sizes, and the new wxDC.Blit is for the new
 297 interface using wxPoints and a wxSize.
 298
 299
 300
 301
 302
 303 What's new in 2.1b2
 304 --------------------
 305
 306 Added the missing wxWindow.GetUpdateRegion() method.
 307
 308 Made a new change in SWIG (update your patches everybody) that
 309 provides a fix for global shadow objects that get an exception in
 310 their __del__ when their extension module has already been deleted.
 311 It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
 312 line 496 if you want to do it by hand.
 313
 314 It is now possible to run through MainLoop more than once in any one
 315 process.  The cleanup that used to happen as MainLoop completed (and
 316 prevented it from running again) has been delayed until the wxc module
 317 is being unloaded by Python.
 318
 319 I fixed a bunch of stuff in the C++ version of wxGrid so it wouldn't
 320 make wxPython look bad.
 321
 322 wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
 323 wxWindow.PopupMenuXY to be consistent with some other methods.
 324
 325 Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.
 326
 327 You can now provide your own app.MainLoop method.  See
 328 wxPython/demo/demoMainLoop.py for an example and some explaination.
 329
 330 Got the in-place-edit for the wxTreeCtrl fixed and added some demo
 331 code to show how to use it.
 332
 333 Put the wxIcon constructor back in for GTK as it now has one that
 334 matches MSW's.
 335
 336 Added wxGrid.GetCells
 337
 338 Added wxSystemSettings static methods as functions with names like
 339 wxSystemSettings_GetSystemColour.
 340
 341 Removed wxPyMenu since using menu callbacks have been depreciated in
 342 wxWindows.  Use wxMenu and events instead.
 343
 344 Added alternate wxBitmap constructor (for MSW only) as
 345       wxBitmapFromData(data, type, width, height, depth = 1)
 346
 347 Added a helper function named wxPyTypeCast that can convert shadow
 348 objects of one type into shadow objects of another type.  (Like doing
 349 a down-cast.)  See the implementation in wx.py for some docs.
 350
 351 Fixed wxImage GetData and SetData to properly use String objects for
 352 data transfer.
 353
 354 Added access methods to wxGridEvent.
 355
 356 New Makefile/Setup files supporting multiple dynamic extension modules
 357 for unix systems.
 358
 359 Fixes for the wxGLCanvas demo to work around a strange bug in gtk.
 360
 361 SWIG support routines now compiled separately instead of being bundled
 362 in wx.cpp.
 363
 364
 365
 366
 367
 368 What's new in 2.1b1
 369 --------------------
 370 Fixed wxComboBox.SetSelection so that it actually sets the selected
 371 item.  (Actually just removed it from wxPython and let it default to
 372 wxChoice.SetSelection which was already doing the right thing.)
 373
 374 Added the Printing Framework.
 375
 376 Switched back to using the wxWindows DLL for the pre-built Win32
 377 version.  The problem was needing to reinitialize static class info
 378 data after loading each extension module.
 379
 380 Lots of little tweaks and additions to reflect changes to various
 381 wxWindows classes.
 382
 383 Fixed a bug with attaching objects to tree items.  Actually was a
 384 symptom of a larger problem with not obtaining the interpreter lock
 385 when doing any Py_DECREFs.
 386
 387 wxSizer and friends.  Sizers are layout tools that manage a colection
 388 of windows and sizers.  Different types of sizers apply different
 389 types of layout algorithms.  You saw it here first!  These classes are
 390 not even in the wxWindows C++ library yet!
 391
 392
 393
 394 What's new in 2.0b9
 395 -------------------
 396 Bug fix for ListCtrl in test4.py (Was a missing file...  DSM!)
 397
 398 Bug fix for occassional GPF on Win32 systems upon termination of a
 399 wxPython application.
 400
 401 Added wxListBox.GetSelections returning selections as a Tuple.
 402
 403 Added a wxTreeItemData that is able to hold any Python object and be
 404 associated with items in a wxTreeCtrl.  Added test pytree.py to show
 405 this feature off.
 406
 407 Added wxSafeYield function.
 408
 409 OpenGL Canvas can be optionally compiled in to wxPython.
 410
 411 Awesome new Demo Framework for showing off wxPython and for learning
 412 how it all works.
 413
 414 The pre-built Win32 version is no longer distributing the wxWindows
 415 DLL.  It is statically linked with the wxWindows library instead.
 416
 417 Added a couple missing items from the docs.
 418
 419 Added wxImage, wxImageHandler, wxPNGHandler, wxJPEGHandler,
 420 wxGIFHandler and wxBMPHandler.
 421
 422 Added new methods to wxTextCtrl.
 423
 424 Fixed some problems with how SWIG was wrapping some wxTreeCtrl
 425 methods.
 426
 427
 428
 429 What's new in 2.0b8
 430 -------------------
 431 Support for using Python threads in wxPython apps.
 432
 433 Several missing methods from various classes.
 434
 435 Various bug fixes.
 436
 437
 438
 439 What's new in 2.0b7
 440 -------------------
 441 Added DLG_PNT and DLG_SZE convienience methods to wxWindow class.
 442
 443 Added missing constructor and other methods for wxMenuItem.
 444
 445
 446
 447 What's new in 2.0b6
 448 -------------------
 449 Just a quickie update to fix the self-installer to be compatible with
 450 Python 1.5.2b2's Registry settings.
 451
 452
 453 What's new in 2.0b5
 454 -------------------
 455 Well obviously the numbering scheme has changed.  I did this to
 456 reflect the fact that this truly is the second major revision of
 457 wxPython, (well the third actually if you count the one I did for
 458 wxWindows 1.68 and then threw away...) and also that it is associated
 459 with the 2.0 version of wxWindows.
 460
 461 I have finally started documenting wxPython.  There are several pages
 462 in the wxWindows documentation tree specifically about wxPython, and I
 463 have added notes within the class references about where and how wxPython
 464 diverges from wxWindows.
 465
 466 Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
 467 window handle.  If you can get the window handle into the python code,
 468 it should just work...  More news on this later.
 469
 470 Added wxImageList, wxToolTip.
 471
 472 Re-enabled wxConfig.DeleteAll() since it is reportedly fixed for the
 473 wxRegConfig class.
 474
 475 As usual, some bug fixes, tweaks, etc.
 476
 477
 478
 479 What's new in 0.5.3
 480 -------------------
 481 Added wxSashWindow, wxSashEvent, wxLayoutAlgorithm, etc.
 482
 483 Various cleanup, tweaks, minor additions, etc. to maintain
 484 compatibility with the current wxWindows.
 485
 486
 487
 488 What's new in 0.5.0
 489 -------------------
 490 Changed the import semantics from "from wxPython import *" to "from
 491 wxPython.wx import *"  This is for people who are worried about
 492 namespace pollution, they can use "from wxPython import wx" and then
 493 prefix all the wxPython identifiers with "wx."
 494
 495 Added wxTaskbarIcon for wxMSW.
 496
 497 Made the events work for wxGrid.
 498
 499 Added wxConfig.
 500
 501 Added wxMiniFrame for wxGTK.
 502
 503 Changed many of the args and return values that were pointers to gdi
 504 objects to references to reflect changes in the wxWindows API.
 505
 506 Other assorted fixes and additions.
 507
 508
 509
 510
 511 What's new in 0.4.2
 512 -------------------
 513
 514 wxPython on wxGTK works!!!  Both dynamic and static on Linux and
 515 static on Solaris have been tested.  Many thanks go to Harm
 516 <H.v.d.Heijden@phys.tue.nl> for his astute detective work on tracking
 517 down a nasty DECREF bug.  Okay so I have to confess that it was just a
 518 DSM (Dumb Stupid Mistake) on my part but it was nasty none the less
 519 because the behavior was so different on different platforms.
 520
 521 The dynamicly loaded module on Solaris is still segfaulting, so it
 522 must have been a different issue all along...
 523
 524
 525
 526 What's New in 0.4
 527 -----------------
 528
 529 1. Worked on wxGTK compatibility.  It is partially working.  On a
 530 Solaris/Sparc box wxPython is working but only when it is statically
 531 linked with the Python interpreter.  When built as a dyamically loaded
 532 extension module, things start acting weirdly and it soon seg-faults.
 533 And on Linux both the statically linked and the dynamically linked
 534 version segfault shortly after starting up.
 535
 536 2. Added Toolbar, StatusBar and SplitterWindow classes.
 537
 538 3. Varioius bug fixes, enhancements, etc.
 539
 540 ----------------------------------------------------------------------
