This method was already provided by wxGTK and wxMSW, but not wxOSX nor
any other ports.
Provide a stub for it in wxWindowBase to allow user code to call it on
all platforms, there is no harm in that even if it doesn't (and can't)
do anything under macOS.
If the window stored as m_winLastFocused in one TLW was reparented to
another one and then destroyed, this pointer to it wasn't updated and
became dangling.
Fix this by using a safe weak reference instead of raw pointer for
m_winLastFocused. This ensures that it can never be used when it becomes
invalid.
Closes#17980.
There is no need to check that calling MSWSetModernEmulationLevel()
changed the registry key in the test, this is just an implementation
detail of this function.
This makes it unnecessary to define wxIE_EMULATION_LEVEL and
wxREGISTRY_IE_PATH (which are both badly named) in the public header.
Finally, improve the error message in MSWSetModernEmulationLevel() and
add another one for failing to reset the emulation level too.
Position of wxProgressDialog cannot be changed directly because the dialog is created in another thread and may exist when SetPosition() is called. New position has be stored in the data structure used to share data between the main thread and the task dialog runner and the real update is done during the cyclic refresh in the dialog thread.
Closes#13546.
Icon for wxProgressDialog cannot be changed directly because the dialog is created in another thread and may not yet exist when SetIcon() is called. We have to store new icon(s) in the data structure used to share data between the main thread and the task dialog runner and wait for a cyclic update.
Closes#17967.
wxGetWinVersion() will return wxWinVersion_Unknown for any MSW version
not recognized by the version of wxWidgets used when building the
application, so it makes sense to use a value higher than all currently
known ones for this constant, so that the checks comparing the result of
wxGetWinVersion() with any known version would still work correctly.
E.g. comparisons like wxGetWinVersion() >= wxWinVersion_Vista will now
continue to work for binaries built using the current wxWidgets even
under some future Windows 11 OS version, unlike before.
The include/wx/msw/private.h header contains a violation of the C++
standards that MSVC tolerates but Clang/LLVM does not.
WinBase.h contains the definition:
#define INVALID_HANDLE_VALUE ((HANDLE)(LONG_PTR)-1)
Which wxWidgets uses in:
template <wxUIntPtr INVALID_VALUE =
(wxUIntPtr)INVALID_HANDLE_VALUE>
The (effective) reinterpret_cast-ing of INVALID_HANDLE_VALUE in
WinBase.h means that the define isn't actually usable as a constant
expression for the template parameter.
Clang has indicated they have no intention of adding an MSVC
compatibility workaround for this problem. See LLVM bug 12116:
https://bugs.llvm.org/show_bug.cgi?id=12116
Given this, rework the wxWidgets header to remove the default
template parameter value (it is not used anywhere).
With this change, it's possible to compile wxWidgets applications
using Clang/LLVM (5.0) under MSVC.
The latest of those checks tested for w32 API 3.3, which is older than
MinGW 3.4 released which is more than 13 years old, so we can safely
drop them (let alone checks for prehistoric 0.5 w32 API).
This incidentally fixes compilation errors due to the use of
wxCHECK_W32API_VERSION() in wx/msw/winundef.h which was now (since
the changes of 8c572c0a77) included before
this macro was defined.
Get rid of ugly wxDynamicCastThis()s in wxMSW wxControl code and add a
new virtual method overridden in wx{Tree,List}Ctrl instead.
Also stop comparing the font with wxSYS_DEFAULT_GUI_FONT, there doesn't
seem to be any good reason to set this particular font for these
controls neither.
In addition to simplifying and de-ugligying the code, this commit
incidentally fixes -Wnonnull-compare warnings in this code from gcc6
too.
Under MSW calling UnblockAndRegisterWithEventLoop() for blocking sockets
is not only useless, but actually harmful when the socket is used from a
worker thread (which is the common case for blocking sockets), as it
means that the main thread will be receiving notifications for the
socket events and modifying the socket object while it's being used from
the other thread, resulting in data races and general brokenness.
This is similar to e18c8fd29a for Unix
sockets.
Closes#17937.
Don't try to write a general purpose class, but provide just the methods
that we need in our code.
This fixes the bug added in 294436c8bb
which resulted in a crash because a literal string, not a BSTR, was
passed to wxBasicString ctor.
* wxGetClipboardData was removed through commit
b375d81499 "Use wxDataObject methods..."
but former usages will break with unreferenced
function as the header still advertises the function
Change-Id: I77e756d2b7d0db7c3833578d2846f4e922a55262
UpdateStyle() function was introduced in edccf428 to synchronize in
SetWindowStyleFlag() style of the control with new style flags just stored
in m_windowStyle.
In 9a8d75f1, storing directly a new flags in m_windowStyle was replaced by
the call to parent's SetWindowStyleFlag().
Because call to parent's SetWindowStyleFlag() updates both m_windowStyle
and actual style of the control for common flags (WS_*, LVS_* flags),
synchronizing the control again with UpdateStyles() is pointless (since
this function does nothing in this context).
Only wxSCROLL style flags need special care because wxListCtrl doesn't
have these styles but the control itself may have them. In order
to preserve them in the call to SetWindowStyleFlag(), we can do the trick
and request the same new scroll style as the actual physical style.
UpdateStyles() is useless now and can be deprecated.
See #17059.
IUnknown interface is used sometimes (e.g. in WinRT implementation of
wxNotificationMessage) alone, without other OLE routines, so it is
helpful to have its code in the separate file to avoid coupling with main
OLE code when only IUnknown implementation is required.
WinRT implementation of wxNotificationMessage requires wxUSE_OLE because
one memeber variable is of type wxAutoULong which is defined in the OLE
utilities collection (oleutils.h).
Library itself can be built successfully when wxUSE_DRAG_AND_DROP==1 and
wxUSE_OLE==0 but several wxDropTarget functions (referred in wxWindowMSW,
wxTextDropTarget, wxFileDropTarget) are reported as missing during linking
the application.
Reorganize the code by putting OLE-dependent code into the blocks
controlled by wxUSE_OLE and by sharing remaining code (like implementation
of wxDataFormat, wxBitmapDataObject, wxFileDataObject, etc.) to allow
building wxDataObject and its specializations also without OLE support.
Since wxDataObject no longer requires OLE support, corresponding check in
checkconf.h can be removed.
Thanks to this additional flexibility, it is possible to use wxClipboard
whether OLE support (wxUSE_OLE) is enabled or not, either with OLE-based
wxDataObject (OLE clipboard) or with wxDataObject decoupled from OLE (Win
clipboard API).
wxMetafileDataObject is a specialization of wxDataObject and its
compilation should be controlled directly by wxUSE_DATAOBJ (like it's done
under wxOSX, see e.g. include/wx/osx/metafile.h), not by
wxUSE_DRAG_AND_DROP.
This method is only used, and defined, when using rich edit controls, so don't
declare it if wxUSE_RICHEDIT==0.
This should fix a link error in this build variant.

While we use wmain() for the compilers that provide it since the changes of
bfa78c63b9, we still didn't handle Unicode
command line arguments not representable in the current Windows code page
correctly when using other compilers (e.g. MinGW).
Now use Win32 ::GetCommandLine() function for them and parse the command line
ourselves instead of relying on non-Unicode-friendly main() arguments which
can't represent arbitrary Unicode strings when not using UTF-8 (which is never
the case under Windows).
Use an enum instead of type-unsafe "int" for the second parameter of the
recently added wxStandardPaths::MakeConfigFileName().
This also avoids unnatural dependency of wxStandardPaths on
wxCONFIG_USE_SUBDIR constant defined in a higher level wxFileConfig class.
No real changes, but just make things a bit more robust and hopefully more
clear.
While we have to keep these conversions enabled by default, they are very
dangerous as they can result in silent data loss on any system not using a
locale with UTF-8 encoding, i.e. always under MSW.
Allow mitigating this by defining wxNO_UNSAFE_WXSTRING_CONV when compiling the
application code using the library, which makes these conversions invisible to
the user code, and so can be used without recompiling the library.
Also add wxUSE_UNSAFE_WXSTRING_CONV which can be set to 0 when compiling the
library to disable these conversions globally for all applications using it.
Closes#11830.
