Announcing wxPython 4.1.0
|
||||
Announcing wxPython 4.1.1
|
||||
=========================
|
||||
|
||||
PyPI: https://pypi.org/project/wxPython/4.1.0
|
||||
PyPI: https://pypi.org/project/wxPython/4.1.1
|
||||
Extras: https://extras.wxPython.org/wxPython4/extras/
|
||||
Pip: ``pip install wxPython==4.1.0``
|
||||
|
||||
Starting with this release wxPython has switched to tracking the
|
||||
wxWidgets master branch (version 3.1.x) for the wxWidgets source code,
|
||||
which wxPython is built upon, and which is included in the wxPython
|
||||
source archives.
|
||||
|
||||
This will be the last release to include binaries for Python 2.7. The
|
||||
code will likely still compile and be compatible with Python 2.7 for
|
||||
some time, but no effort will be put into keeping it that way.
|
||||
|
||||
Pip: ``pip install wxPython==4.1.1``
|
||||
|
||||
New and improved in this release:
|
||||
|
||||
* Add a sample for wx.Font.AddPrivateFont to the demo.
|
||||
* This should have been mentioned in the notes for the last release,
|
||||
but alas, it wandered away and got lost. wxWidgets is now validating
|
||||
the flags passed when adding items to a sizer, to ensure that they
|
||||
are the correct flags for the type of the sizer. If the given flags
|
||||
do not make sense, for example using horizontal alignment flags in a
|
||||
horizontal box sizer, then a wxAssertionError error is raised.
|
||||
|
||||
* Added wrappers for the OSXEnableAutomaticQuoteSubstitution,
|
||||
OSXEnableAutomaticDashSubstitution, and
|
||||
OSXDisableAllSmartSubstitutions methods in wx.TextCtrl. Also added
|
||||
OSXEnableAutomaticTabbing in wx.App.
|
||||
* Fixed missing binder for wxEVT_STC_AUTOCOMP_SELECTION_CHANGE. (#1613)
|
||||
|
||||
* Added wx.ColourDialogEvent, wx.DCTextBgColourChanger,
|
||||
wx.DCTextBgModeChanger, wx.grid.GridCellDateRenderer,
|
||||
wx.grid.GridCellDateEditor, wx.SystemAppearance, etc.
|
||||
* DataViewModel.HasValue can be overridden and will inform the
|
||||
DataViewCtrl whether or not an item and column has data. If HasValue
|
||||
returns False, then GetValue for that item/col will not be called.
|
||||
This allows a distinction between a truly empty cell, and one that
|
||||
has a value even if it is an empty string. (#1600)
|
||||
|
||||
* Many of the deprecated items in wxWidgets and wxPython are being or
|
||||
have been removed. Be sure to test your code in a recent 4.0.x
|
||||
release with warnings enabled so you can see which class, method or
|
||||
function calls you need to change.
|
||||
* Added flag that allows blocking of item dragging in the
|
||||
UltimateListControl class. (PR#1620)
|
||||
|
||||
* Bug fixes in wx.lib.calendar: key navigation across month boundaries
|
||||
is now possible; key navigation now sets the date and fires the
|
||||
EVT_CALENDAR event; setter APIs now set the date correctly (#1230).
|
||||
* Add the column index to notification events in UltimateListControl
|
||||
(PR#1630)
|
||||
|
||||
* Switch to using a wx.Overlay in the Widget Inspection Tool to
|
||||
highlight widgets when running on a GTK3 port.
|
||||
* Added orientation parameter to UltimateListControl.GetScrollPos.
|
||||
(PR#1632)
|
||||
|
||||
* Fixed issue in wx.lib.agw.customtreectrl where the label editor
|
||||
could remain stuck forever (#1235).
|
||||
* wx.lib.agw.aui.AuiNotebook RemovePage() now hides the removed page,
|
||||
so it needs to be shown again if it is reused in another place.
|
||||
(PR#1668)
|
||||
|
||||
* Grafted on a EnableSystemTheme method to the classes which support
|
||||
it. This can be used to disable the default system theme on Windows
|
||||
for native widgets like wx.ListCtrl, wx.TreeCtrl and
|
||||
wx.dataview.DataViewCtrl. It has no effect on the other platforms.
|
||||
* Fixed issue that could modify `bytes` objects under Python. (PR#1680)
|
||||
|
||||
* The wx.WS_EX_VALIDATE_RECURSIVELY extended style flag is obsolete,
|
||||
as it is now the default (and only) behavior. The style flag has
|
||||
been added back into wxPython for compatibility, but with a zero
|
||||
value. You can just stop using it in your code with no change in
|
||||
behavior. (#1278)
|
||||
* Added wx.lib.agw.aui.EVT_AUI_PANE_CLOSE event which is sent when a
|
||||
AUI (the agw version) Pane has been closed (after it has been
|
||||
closed, not when it is about to be closed, which is when
|
||||
EVT_AUI_PANE_CLOSE is sent.) (PR#1628)
|
||||
|
||||
* Fix a sometimes crash when using a wx.Overlay by letting the
|
||||
wx.DCOverlay hold a reference to the DC, to ensure that the
|
||||
DCOverlay is destroyed first. (PR#1301)
|
||||
* Exposed the wx.DC methods GetGraphicsContext and SetGraphicsContext.
|
||||
Depending on the platform and the type of the DC, there may be a
|
||||
wx.GraphicsContext used for the implementation of the DC. If so, the
|
||||
GetGraphicsContext method enables access to it. Be sure to check
|
||||
that the return value is not None before trying to use it.
|
||||
|
||||
* Replaced the Vagrant VMs used for building wxPython for various
|
||||
Linux distros with Docker images.
|
||||
* Simplified the implementation of the wx.App.InitLocale method. See the
|
||||
MigrationGuide for more information.
|
||||
|
||||
* Add some missing methods in wx.adv.BitmapComboBox (#1307)
|
||||
* Added wx.lib.agw.aui.AUI_DOCKART_HINT_WINDOW_BORDER_COLOUR constant
|
||||
so the hint window border color can be themed as well.
|
||||
|
||||
* Added the wx.svg package which contains code for parsing SVG
|
||||
(Scalable Vector Graphics) files, and also code for integrating with
|
||||
wxPython. It can rasterize the SVG to a wx.Bitmap of any size with
|
||||
no loss of quality, and it can also render the SVG directly to a
|
||||
wx.GraphicsContext using the GC's drawing primitives. (PR #1323)
|
||||
* The wx.lib.mixins.listCtrl.CheckListCtrlMixin is now obsolete
|
||||
because wx.ListCtrl has new functionality which does pretty much the
|
||||
same thing. In fact there is some overlap in method names which may
|
||||
trip up some use cases. It is advised to drop the use of
|
||||
CheckListCtrlMixin and just use the wx.ListBox functionality. You
|
||||
will need to call EnableCheckBoxes to turn it on, and you may need
|
||||
to change some event handlers or overloaded methods.
|
||||
|
||||
* Ported the embedding sample from Classic, which shows how to use
|
||||
wxPython from a C++ wxWidgets application that embeds Python. (PR
|
||||
#1353)
|
||||
* wx.html2.WebView is now able to use Microsoft's Edge browser
|
||||
component as its backend renderer. This should improve the
|
||||
capabilities of the WebView widget on Windows, and be more
|
||||
consistent with the WebViews on the other platforms, compared to the
|
||||
original IE 11 backend. Using this backed requires that a new-ish
|
||||
version of the Edge browser is installed on the end user's computer.
|
||||
|
||||
* Fixed wx.GetApp() to use wxWidgets' global wxApp instance instead of
|
||||
maintaining its own pointer. This way, if the wxApp is created by
|
||||
C++ code wxPython will still be able to get access to it. (#1126)
|
||||
* Added the wx.Image.ConvertToRegion method. This lets you create a
|
||||
wx.Region from an image and a specified color or the mask if the
|
||||
image has one. This was done to workaround a bug in wxMac, but it
|
||||
seems worthwhile enough to keep it around even after the bug was
|
||||
fixed.
|
||||
|
||||
* Added wrappers for the wx.ActivityIndicator class.
|
||||
* Added the missing context manager methods for wx.LogNull. (#1842)
|
||||
|
||||
* Added wrappers for the wx.CollapsibleHeaderCtrl class.
|
||||
|
||||
* Fixed issues in PlotCanvas around displaying and using
|
||||
scrollbars. (#1428)
|
||||
|
||||
* Added wx.msw.CHMHelpController, and also a wx.HelpController factory
|
||||
function that creates an instance of the best Help Controller for
|
||||
the platform. (#1536)
|
||||
|
||||
* Added wx.adv.GenericAnimationCtrl so the generic version of the
|
||||
animation classes can be used even on the platforms that have a
|
||||
native version. Note that due to internal changes to support both
|
||||
types of animations, some API changes in how the Animation objects
|
||||
are created. See the AnimationCtrl.py sample in the demo for the
|
||||
various usage patterns (#1579)
|
||||
|
||||
* Added wrappers for the wx.grid.GridBlockCoords, wx.grid.GridBlocks,
|
||||
and wx.grid.GridBlockDiffResult classes, as well as associated new
|
||||
methods in the wx.grid.Grid class. These provide a new way to
|
||||
interact with blocks of selected cells, including an iterator
|
||||
interface in wx.grid.GridBlocks which should be a more efficient
|
||||
(time and memory) way to process large groups of selections.
|
||||
* Refactored ScrolledThumbnail out of agw.ThumbnailCtrl so as to be
|
||||
usable outside of ThumbnailCtrl.
