This function can be used to check if drawing on wxClientDC actually
works. This has to be a run-time, rather than compile-time, check
because in wxGTK3 this depends on the backend being used: wxClientDC
only doesn't work with Wayland, but does work with X11 (and, less
importantly, Win32) backend(s).
Currently the wxWindow parameter of this function is not used but it
could be useful in the future and it will be simpler to allow not
specifying it (by defaulting it to nullptr) than to add it later, so it
seems better to have it.
This parameter was always "true" in the existing calls to this function
and the underlying UseClippingView() didn't support passing "false" to
it anyhow, so it seems simpler and more clear to just remove the
parameter.
It also avoids clang warnings about it being unused.
No real changes.
We need to use a native clip view for things to behave correctly under
this OS version, otherwise scrollbars can be overdrawn by the window
contents.

Replace user-specified empty constructors and destructors with the
compiler-generated versions, which has a number of advantages for code
generation, in addition to being more clear.

Closes#24058.
The new function does the same thing as the Mac-specific
OSXMakeDPIFromScaleFactor() that it replaces but is also defined in
wxGTK where it will be used too.
Having this line is not useful at all as it doesn't contain any
information and shouldn't be filled in the future as git-shortlog can
provide the information about people who changed the given file more
more reliably than consulting the comments in any case.
Keep the non-blank lines for historical purposes.
While the window was somehow resized on its own under Mac (and only
there) after the initial creation, it didn't have the correct size
initially if we didn't give it to it, so provide a Mac-specific
implementation of wxEVT_SIZE handler too, which fixes this and allows to
remove an ugly Mac-specific workaround from the sample.
Instead of just declaring the function inline in the common code, do it
in a header included from both common C++ and Mac Objective C++ sources.
No real changes.
This is the standard and there doesn't seem to be any contemporary
systems where this is not the case. The configure check for it was
originally added in 101c20d554 (attempting to fix sa_handler signature
for IRIX, 2000-04-01), but IRIX is not supported/doesn't exist any
longer, so don't waste time on checking for this.
The real motivation for this change is that the test failed in CMake
builds, showing just
-- Performing Test wxTYPE_SA_HANDLER_IS_INT - Failed
in the log and then resulting in -fpermissive warnings when assigning
wxFatalSignalHandler to sa_handler and it's simpler to just remove the
check than to debug it.
See #23664.
This avoids crash if wxVSCROLL or wxHSCROLL is used with wxGLCanvas
which calls wxWindow::Create() after calling DontCreatePeer() because
the Create() tries to use the not (yet) existent peer in
MacCreateScrollBars().
Avoid this problem by moving the call to MacCreateScrollBars() to
MacPostControlCreate(), which doesn't change anything for the windows
that do not call DontCreatePeer(), but ensures that the peer already
exists by the time MacPostControlCreate() is called for those that do.
Closes#23536.
Avoid implicit copy constructor warnings by using
wxDECLARE_DYNAMIC_CLASS_NO_ASSIGN_DEF_COPY/wxDECLARE_NO_ASSIGN_DEF_COPY
instead of wxDECLARE_DYNAMIC_CLASS_NO_ASSIGN.
Closes#23625.
Closes#23626.
Clarify that it is 1 by default in the documentation, instead of
implying that it's off by default and needs to be enabled.
Improve the description of this option in setup.h files.
And also document this compilation option in the summary page.
Replace wx hash maps of tags and file type data with the standard
containers.
Also use auto instead of the explicit iterator type in the code using
these maps.
This symbol is similar to the existing wxNO_IMPLICIT_WXSTRING_ENCODING
and can be defined when building the application (as opposed to when
building the library) to disable implicit wxString conversions to
pointer types, i.e. char*, wchat_t* and void*.
This makes the just added wxUSE_CHAR_CONV_IN_WXSTRING library build
option unnecessary, so remove it.
wxString is always based on std::[w]string since 2c0c727f49 (Remove wx
own wxStringImpl implementation, 2022-11-16) and all containers use
standard containers by default too now -- and there is a separate
wxUSE_STD_CONTAINERS for this anyhow.
The only remaining use of wxUSE_STL was as the default value for
wxUSE_STD_STRING_CONV_IN_WXSTRING option, but it's not really needed
for this neither, and this option can just be set to 0 by default.
Also add wxUSE_CHAR_CONV_IN_WXSTRING which can now be set to 0 too to
disable all unwanted implicit conversions (even "safe" ones, to wide
strings, in addition to the unsafe ones to narrow strings that could be
already disabled with wxUSE_UNSAFE_WXSTRING_CONV) to allow people who
don't want to have any implicit conversions at all to do it.
Keep --enable-stl configure option for compatibility, but warn if it is
used to tell people that it is not needed any longer.
This is mostly, even if not completely, compatible with the previous
default build using wxUSE_STD_CONTAINERS=0, so try enabling this by
default again. Hopefully it should work better now than the last time we
tried it, see 01871bf642 (Add wxUSE_STD_CONTAINERS and turn it on by
default., 2011-03-30) and the subsequent 7311debd0d (Don't use the
standard containers by default., 2011-05-13).
See #22718.
This option can also be used under MSW, so move it to the common setup.h
instead of having it in setup.h.in only.
Also do the same thing for wxUSE_UTF8_LOCALE_ONLY, even if it's less
clear if this one is really useful in non-Unix environment.
This replaces the previously implemented wxWebViewWindowInfo.
It explicitly breaks the previous API to enable WebKitGTK
integration and to make the usage in application code less error prone.
A new event wxEVT_WEBVIEW_NEWWINDOW_FEATURES is added to allow
access to the window features and the child web view.
In 40ff38b63b wxWebView::GetNativeConfiguration() was
added which isn't suitable if multiple wxWebViewEdge instances are created with
different options (as they must share the same options). To prevent such errors
the previous method is replaced by the new class wxWebViewConfiguration which
can be shared between various wxWebView instances.
This explicitly breaks API to improve usage.
In the future the new class could also enable a good way to wrap various
common options/configurations available via native API.
Add new class wxWebViewWindowInfo:
This new class returned by wxWebViewEvent::GetTargetWindowInfo() allows
to get information about the window that is about to be opened and to
set the window that will be used to display the content.
It didn't make any sense to have Create() functions in this class
without the default ctor as they could be never used -- calling them
would result in creating the window twice.
Add the default ctor to make this class more similar to all the other
windows.
They were not used anyhow and could conflict with the other packages
defining them.
We also don't need to update the version in this file now.
See #23162.
Drop disabled by default and pretty useless memory tracing code and all
the overlapping and poorly documented build options related to it.
Remove memory.cpp entirely and update all the make/project files, but
preserve the now completely trivial wx/memory.h for compatibility and
also keep including wx/string.h from wx/object.h as it seems like a lot
of existing code actually depends on this, even if it should not.
Replace the options in the propgrid sample with a couple of other
debug-related options that were not used before to avoid leaving the
"Debugging Section" completely empty.
Assume they are always 1 now, there is no good reason to ever set them
to 0 any more.
Note that we still keep wxUSE_STD_IOSTREAM for now, but we can drop
wxUSE_STD_DEFAULT as it's not worth having it just for this single
option (previously it was used as the default value for 3 of them).
Always use thread_local as we can rely on compiler TLS support working
under Windows 7 and later.
There are some known problems in MinGW thread local variable support,
but they only affect (obsolete) 32-bit builds and will hopefully be
fixed in this compiler soon.
See #22917.
This was needed in ANSI build only and so isn't needed any longer now
that it's not supported any more, so simplify the code and stop passing
fonts/encodings everywhere when we don't actually need them at all.
Don't use compiler-specific __thread and use the standard keyword
instead.
Keep the existing TLS-related macros for compatibility, but remove our
custom implementation of them, so that they're always trivial now.
Instead of setting clipping for client area for wxOSX windows
with non-native borders in the common wxGCDC::DestroyClippingRegion()
we can encapsulate this operation in dedicated DestroyClippingRegion()
implementation in wxWindowDC.
See #19108.
See #22914.
This is a combination of running clang-tidy with modernize-use-nullptr
check for some ports (GTK, X11, OSX) and manual changes to the ports for
which it couldn't be used easily (MSW, DFB) and also manually updating
the docs.
Also replace NULL with null or nullptr in the comments as this is more
consistent with the use of nullptr in the code and makes it simpler to
grep for the remaining occurrences of NULL itself.
And also use null in the assert messages.
Only a few occurrences of "NULL" are still left in non-C files, mostly
corresponding to unclear comments or string output which it might not be
safe to change.
Always use std::unordered_{map,set} when we use them at all, don't
bother with checking for their availability and with tr1 or even older
alternatives.
