Many of the Draw methods of wx.DC have alternate forms in C++ that take -wxPoint or wxSize parameters (let's call these Type A) instead of -the individual x, y, width, height, etc. parameters (and we'll call -these Type B). In the rest of the library I normally made the Type -A forms of the methods be the default method with the "normal" name, -and had renamed the Type B forms of the methods to some similar -name. For example in wx.Window we have these Python methods:
+[Changed in 2.5.2.x] In wxPython 2.5.1.5 there was a new +implementation of the wx.DC Draw and other methods that broke +backwards compatibility in the name of consistency. That change has +been reverted and the wx.DC Draw methods with 2.4 compatible +signatures have been restored. In addition a new set of methods have +been added that take wx.Point and/or wx.Size parameters instead of +separate integer parameters. The Draw and etc. methods now available +in the wx.DC class are:

For various reasons the new Type A methods in wx.DC were never added -and the existing Type B methods were never renamed. Now that lots -of other things are also changing in wxPython it has been decided that -it is a good time to also do the method renaming in wx.DC too in order -to be consistent with the rest of the library.

If you have code that draws on a DC and you are using the new wx -namespace then you will get errors because of these changes, but -it should be easy to fix the code. You can either change the name of -the Type B method called to the names shown above, or just add -parentheses around the parameters as needed to turn them into tuples -and let the SWIG typemaps turn them into the wx.Point or wx.Size -object that is expected. Then you will be calling the new Type A -method. For example, if you had this code before:
--dc.DrawRectangle(x, y, width, height) --
You could either continue to use the Type B method by changing the -name to DrawRectangleXY, or just change it to the new Type A by -adding some parentheses like this:
--dc.DrawRectangle((x, y), (width, height)) --
Or if you were already using a point and size like this:
--dc.DrawRectangle(p.x, p.y, s.width, s.height) --
Then you can just simplify it like this:
--dc.DrawRectangle(p, s) +SetClippingRegion(self, x, y, width, height) +SetClippingRegionPointSize(self, pt, sz) +SetClippingRegionAsRegion(self, region) +SetClippingRect(self, rect)-

+wrappers will figure out what to do. [Changed in 2.5.2.x] +AddWindow, AddSizer, AddSpacer and etc. will now issue a +DeprecationWarning. [Changed in 2.5.4.x] These methods have now +been undeprecated at the request of Riaan Booysen, the Boa Constructor +team lead. They are now just simple compatibility aliases for Add, +and etc. +[Changed in 2.5.2.x] The Sizers have had some fundamental internal +changes in the 2.5.2.x release intended to make them do more of the +"Right Thing" but also be as backwards compatible as possible. +First a bit about how things used to work:
++++
+- The size that a window had when Add()ed to the sizer was assumed +to be its minimal size, and that size would always be used by +default when calculating layout size and positions, and the +sizer itself would keep track of that minimal size.
+- If the window item was added with the wx.ADJUST_MINSIZE +flag then when layout was calculated the item's GetBestSize +would be used to reset the minimal size that the sizer used.
+
The main thrust of the new Sizer changes was to make behavior like +wx.ADJUST_MINSIZE be the default, and also to push the tracking of +the minimal size to the window itself (since it knows its own needs) +instead of having the sizer take care of it. Consequently these +changes were made:
++++
+- The wx.FIXED_MINSIZE flag was added to allow for the old +behavior. When this flag is used the size a window has when +added to the sizer will be treated as its minimal size and it +will not be readjusted on each layout.
+- The min size stored in wx.Window and settable with +SetSizeHints or SetMinSize will by default be used by +the sizer (if it was set) as the minimal size of the sizer item. +If the min size was not set (or was only partially set) then the +window's best size is fetched and it is used instead of (or +blended with) the min size. wx.Window.GetBestFittingSize +was added to facilitate getting the size to be used by the +sizers.
+- The best size of a window is cached so it doesn't need to +recaculated on every layout. wx.Window.InvalidateBestSize +was added and should be called (usually just internally in +control methods) whenever something is done that would make the +best size change.
+- All wxControls were changed to set the minsize to what is passed +to the constructor or Create method, and also to set the real +size of the control to the blending of the min size and best +size. wx.Window.SetBestFittingSize was added to help with +this, although most controls don't need to call it directly +because it is called indirectly via the SetInitialSize +called in the base classes.
+
At this time, the only situation known not to work the same as before +is the following:
++win = SomeWidget(parent) +win.SetSize(SomeNonDefaultSize) +sizer.Add(win) ++
In this case the old code would have used the new size as the minimum, +but now the sizer will use the default size as the minimum rather than +the size set later. It is an easy fix though, just move the +specification of the size to the constructor (assuming that SomeWidget +will set its minsize there like the rest of the controls do) or call +SetMinSize instead of SetSize.
+In order to fit well with this new scheme of things, all wxControls or +custom controls should do the following things. (Depending on how +they are used you may also want to do the same thing for non-control +custom windows.)
+++
+- +
Either override or inherit a meaningful DoGetBestSize method +that calculates whatever size is "best" for the control. Once +that size is calculated then there should normally be a call to +CacheBestSize to save it for later use, unless for some +reason you want the best size to be recalculated on every +layout.
+Note: In order to successfully override DoGetBestSize in +Python the class needs to be derived from wx.PyWindow, +wx.PyControl, or etc. If your class instead derives from +one of the standard wx classes then just be sure that the min +size gets explicitly set to what would have been the best size +and things should work properly in almost all situations.
+- +
Any method that changes the attributes of the control such that +the best size will change should call InvalidateBestSize so +it will be recalculated the next time it is needed.
+- +
The control's constructor and/or Create method should ensure +that the minsize is set to the size passed in, and that the +control is sized to a blending of the min size and best size. +This can be done by calling SetBestFittingSize.
+
Prior to 2.5 the PNG image handler would convert all alpha channel +information to a mask when the image was loaded. Pixels that were +more than halfway transparent would be made fully transparent by the +mask and the rest would be made fully opaque.
+In 2.5 the image handler has been updated to preserve the alpha +channel and will now only create a mask when all the pixels in the +image are either fully transparent or fully opaque. In addition, the +wx.DC.DrawBitmap and wx.DC.Blit methods are able to correctly blend +the pixels in the image with partially transparent alpha values.
+If you are using a PNG with an alpha channel but you need to have a +wx.Mask like you automatically got in 2.4 then you can do one of the +following:
++++
+- Edit the image and make all the partially transparent pixels be +fully transparent.
+- Use a different image type.
+- Set a mask based on colour after you load the image.

[Changed in 2.5.2.x]
+The wx.ogl module was deprecated in version 2.5.2 in favor of the new +Python port of the OGL library located at wx.lib.ogl contributed by +Pierre Hjälm. Starting in version 2.5.5 the old ogl is no longer +being built in the distributed binaries, however the source code is +still in the source tree so people can built it themselves if desired.
+The reason this changes was done was to greatly extend the life of OGL +within wxPython by making it more easily maintainable and less prone +to getting rusty as there seems to be less and less interest in +maintaining the C++ version.
+There are only a few known compatibility issues at this time. First +is the location of OGL. The old version was located in the +wx.ogl module, and the new version is in the wx.lib.ogl package. So +this just means that to start using the new version you need to adjust +your imports. So if your code currently has something like this:
++import wx +import wx.ogl as ogl ++
Then just change it to this:
++import wx +import wx.lib.ogl as ogl ++
The other compatibility issue deals with removing a wart in the +original API that was necessary in order to allow overloaded methods +in derived classes to call the same method in the base class when +using the old SWIG. Instead dedaling with the wart you can now just +call the base class method like you woudl for any other Python class. +For example, if you had to do something like this previously:
++class MyDividedShape(ogl.DividedShape): + ... + def OnSizingEndDragLeft(self, pt, x, y, keys, attch): + self.base_OnSizingEndDragLeft(pt, x, y, keys, attch) + ... ++
You will need to change it to be like this:

Instead of over a dozen separate extension modules linked together into a single extension module, the "core" module is now just a few extensions that are linked independently, and then merged together later into the main namespace via Python code.
Because of the above and also because of the way the new SWIG works, the "internal" module names have changed, but you shouldn't have been -using them anyway so it shouldn't bother you. ;-)

+wx.TaskbarIcon now works on all three platforms, although for wxGTK it +depends on support from the Window Manager. On OS X the icon replaces +the application's icon on the dock and when you right click on it the +app's default popup menu is merged with the wx.TaskBarIcon's menu. +Because of how it is implemented on the Mac using the Dock most of the +TaskBarIcon events will _not_ be emitted on that platform, but since +98% of the time you simply want to display an icon and have a popup +menu it shouldn't be much of a problem. You can still use the other +events on the other platforms, you'll just want to be sure that you +can do everything you want via the menu too.
+Since popping up a menu is the most common thing to do with a +TaskBarIcon the class has some new built in functionality to +facilitate that. To use the TaskBarIcon in this new way, simply +derive a new class from TaskBarIcon and implement a CreatePopupMenu +method that creates and returns the menu. That's all there is to it, +besides binding event handlers for the menu items of course. Take a +look at the DemoTaskBarIcon class in the demo/Main.py module for an +example.
+NOTE: Unfortunately due to being able to support virtualizing +CreatePopupMenu the C++ TaskBarIcon instance now holds a reference to +the Python instance, and so you will need to explicitly Destroy() your +TaskBarIcon instance when you are done with it. (Like you do with +wx.Dialogs.) If you don't destroy it then wxWidgets will assume that +you want the app to keep running with just the icon in the task bar +and the MainLoop will not exit.

+Starting with 2.5.3.0 the Unicode versions of wxPython will no longer +have a 'u' appended to the fourth component of the version number. +Please check for the presence of "unicode" in the wx.PlatformInfo +tuple instead. (This tuple of strings has been available since the +first 2.5 version.) For example:
++if "unicode" in wx.PlatformInfo: + # do whatever + ... ++
[Changed in 2.5.3.x]
+Starting with 2.5.3.0 the wx and wxPython package directories will be +installed in a subdirectory of the site-packages directory, instead of +directly in site-packages. This is done to help facilitate having +multiple versions of wxPython installed side-by-side. Why would you +want to do this? One possible scenario is you have an app that +requires wxPython 2.4 but you want to use the newest 2.5 to do your +own development with. Or perhaps you want to be able to test your app +with several different versions of wxPython to ensure compatibility. +Before everyone panics, rest asured that if you only install one +version of wxPython then you should notice no difference in how things +work.
+In addition to installing wxPython into a "versioned" subdirectory of +site-packages, a file named wx.pth is optionally installed that will +contain the name of the versioned subdirectory. This will cause that +subdirectory to be automatically added to the sys.path and so doing an +"import wx" will find the package in the subdirectory like it would +have if it was still located directly in site-packages. I say +"optionally" above because that is how you can control which install +of wxPython is the default one. Which ever version installs the +wx.pth file will be the one that is imported with a plain "import wx" +statement. Of course you can always manipulate that by editing the +wx.pth file, or by setting PYTHONPATH in the environment, or by the +method described in the next paragraph.
+Finally, a new module named wxversion.py is installed to the +site-packages directory. It can be used to manipulate the sys.path at +runtime so your applications can select which version of wxPython they +would like to to have imported. You use it like this:
+
+import wxversion
+wxversion.select("2.4")
+import wx
+
+Then even though a 2.5 version of wxPython may be the default the +application that does the above the first time that wx is imported +will actually get a 2.4 version. NOTE: There isn't actually a 2.4 +version of wxPython that supports this, but there will be.

If +you use this style but would still like to have the normal tab +traversal take place then you should send your own +wx.NavigationKeyEvent from the wx.EVT_KEY_DOWN handler. There is a +new Navigate method in the wx.Window class to help send the event and +it is used something like this:
++flags = wx.NavigationKeyEvent.IsForward +if event.ShiftDown(): + flags = wx.NavigationKeyEvent.IsBackward +if event.ControlDown(): + flags |= wx.NavigationKeyEvent.WinChange +self.Navigate(flags) +
