wxWidgets 3.1.5 Release Notes
|
|
=============================
|
|
|
|
Welcome to the latest development release of wxWidgets, a free and open source
|
|
cross-platform C++ framework for writing advanced GUI applications using native
|
|
controls.
|
|
|
|
wxWidgets allows you to write native-looking GUI applications for all the major
|
|
desktop platforms and also helps with abstracting the differences in the non-GUI
|
|
aspects between them. It is free for the use in both open source and commercial
|
|
applications, comes with the full, easy to read and modify, source and extensive
|
|
documentation and a collection of more than a hundred examples. You can learn
|
|
more about wxWidgets at:
|
|
|
|
* https://www.wxwidgets.org/
|
|
|
|
Documentation is available online at:
|
|
|
|
* https://docs.wxwidgets.org/3.1.5/
|
|
|
|
wxWidgets sources and binaries for the selected platforms are available for
|
|
download from:
|
|
|
|
* https://www.wxwidgets.org/downloads/
|
|
|
|
or, for a more more permanent but less convenient to use link, from
|
|
|
|
* https://github.com/wxWidgets/wxWidgets/releases/tag/v3.1.5/
|
|
|
|
Please see https://docs.wxwidgets.org/3.1.5/overview_install.html for full
|
|
installation instructions.

Changes since 3.1.4
|
|
-------------------
|
|
|
|
In the nine months since the previous release, there have been more than 1600
|
|
commits from 70 unique contributors (40 with multiple contributions), so it is
|
|
impossible to summarize all the changes in this document without making it too
|
|
long, please see the fuller changelog at
|
|
|
|
https://raw.githubusercontent.com/wxWidgets/wxWidgets/v3.1.5/docs/changes.txt
|
|
|
|
for more details, but here are some of the most important changes:
|
|
|
|
- New wxWebRequest and related classes provide a simple way to use HTTPS and
|
|
HTTP/2 from wxWidgets applications using native libraries or libcurl.
|
|
- Support EGL in wxGLCanvas and Wayland in wxMediaCtrl under Linux.
|
|
- Many appearance and other fixes for macOS 11.
|
|
- More improvements to wxGrid UI, API and performance.
|
|
- wxImage improvements: add alpha support in Paste() and clipboard support.
|
|
- API additions: wxPersistentComboBox, wxFileName::ResolveLink(),
|
|
wxFileHistory::SetMenuPathStyle(), wxString::utf8_string(), wxEVT_FULLSCREEN.
|
|
- Improvements: wxConfig now supports 64-bit integers, wxLog uses millisecond
|
|
resolution in timestamps, XRC files can be loaded from URLs.
|
|
- Yet more bug fixes, fixes for API inconsistencies and optimizations, notably
|
|
in wxDataViewCtrl, wxListCtrl, wxPropertyGrid.
|
|
|
|
Notice that in spite of all the changes, this release remains almost completely
|
|
compatible with 3.1.4 at the API level, so upgrading to it if you're already
|
|
using wxWidgets 3 should be straightforward.
|
|
|
|
|
|
Changes since 3.0
|
|

Licence
|
|
-------
|
|
|
|

|
|
|
|
* docs/preamble.txt
|
|
* docs/licence.txt
|

|
|
|
|
Although this may seem complex, it is there to allow authors of proprietary,
|
|
commercial applications to use wxWidgets in addition to those writing GPL'ed
|
|
applications. In summary, the licence is LGPL plus a clause allowing
|
|
unrestricted distribution of application binaries. To answer a FAQ, you don't
|
|
have to distribute any source if you wish to write commercial applications using
|
|
wxWidgets.
|
|
|
|
However, if you distribute wxGTK, wxQt or wxMotif (with Lesstif) version of your
|
|
application, don't forget that it is linked against GTK+, Qt or Lesstif, which
|
|
are covered by LGPL *without* exception notice and so is bound by its
|
|
requirements.
|
|
|
|
If you use TIFF image handler, please see src/tiff/COPYRIGHT for libtiff licence
|
|
details.
|
|
|
|
If you use JPEG image handler, documentation for your program should contain
|
|
following sentence: "This software is based in part on the work of the
|
|
Independent JPEG Group". See src/jpeg/README for details.
|
|
|
|
If you use wxRegEx class on a system without native regular expressions support
|
|
(i.e. MS Windows), see src/regex/COPYRIGHT file for Henry Spencer's regular
|
|
expression library copyright.
|
|
|
|
If you use wxXML classes or XRC, see src/expat/COPYING for licence details.

The wxWidgets bug tracker can be found here:
|
|
|
|
* https://trac.wxwidgets.org/newticket
|
|
|
|
Please use the search function of our Trac installation to find any possibly
|
|
relevant bugs before reporting new ones. Also please notice that often trying to
|
|
correct the bug yourself is the quickest way to fix it. Even if you fail to do
|
|
it, you may discover valuable information allowing us to fix it while doing it.
|
|
We also give much higher priority to bug reports with patches fixing the
|
|
problems so this ensures that your report will be addressed sooner.
