This implementation is based on javascript 'window.find()'
https://developer.mozilla.org/en-US/docs/Web/API/Window/find
It's not standard, but implemented in most browsers.
It's not a complete implementation as it can't determine how
many search results can be found.
If the backends API provides a native find interface it should be
used instead of this implementation, but it's good fallback.
Send EVT_WEBVIEW_NAVIGATING, EVT_WEBVIEW_NAVIGATED and EVT_WEBVIEW_LOADED
when an anchor is clicked within a document. This kind of navigation
cannot be vetoed.

If a wxWebRequestCURL object is canceled or deleted before its transfer
is complete, we need to manually close its active socket. Record each
transfer’s active socket in wxWebSessionCURL::SocketCallback so can use
it if needed.
Previously, this was done using curl_easy_getinfo, but this required
some compile time and run time checks and could fail in some specific
cases. Recording the socket ourselves significantly simplifies the code
and should always work.
Remove platform-specific translations.
This is unnecessarily complicated for the single string that we
currently use this for, so just handle it specially.
Also some other minor translation-related improvements.

When using the socket poller implementation using wxEventLoopSource
objects to monitor sockets, the operation
wxEventLoopBase::AddSourceForFD(... can sometimes return NULL. In these
cases the socket will not be monitored as needed. The only option seems
to be to cancel the transfer and report a failure
Previously wxWebRequestCURL objects were canceled by removing their
CURL easy handle from the CURLM multihandle. Unfortunately the really
only pauses the connection and does not truly cancel it. This commit
tries to stop the transfer by retrieving the active socket from the CURL
handle for the transfer and closing it.
There are some complications in doing this because the option curl uses
to get the socket have changed over the years. A combination of compile
time and run time checks are used to use the appropriate options to get
the socket. However in the case of 64bit windows using a curl version
older than 7.45.0 simply won’t have an usable option. In this case,
it seems nothing can be done.
At various points in a transfer being managed by the wxWebSessionCURL
class we need to perform operations on a wxWebRequestCURL object.
However it’s possible for the request object to be deleted while the
transfer is in progress.
To ensure that the request objects are valid, keep track of the request
objects with a hash map. Objects are added to the map when a transfer is
started and removed when the transfer is complete or in the request’s
destructor.
Currently for wxWebRequestCURL objects using memory storage, a download
is processed by appending to a wxMemoryBuffer each time the write
callback is called. For a large transfer, this can result in many, many
reallocation calls and can block the main application.
This commit uses the progress callback for wxWebRequestCURL objects
added in a previous commit to set a minimum size for the buffer as soon
as it is known.
This commit adds a progress callback for use with wxWebRequestCURL
objects. This has some complications because over the years curl has
changed the signature of the callback.
A combination of compile-time and run-time checks is used to make sure
the appropriate callback and preferred return value are used.
Instead of having wxWebSessionCURL run a worker thread that uses curl
to monitor and process network activity, set up a separate socket
poller class to monitor socket activity. The socket poller class will
throw an event back to wxWebSessionCURL when it detects activity on the
sockets so that it can tell curl to process the activity in the main
thread.
This will allow reusing the same strings in other places.
Also use this as opportunity to add "msw" as the (preferred) synonym for
"win" for general consistency.
This can be useful to implement custom handling of WM_COMMAND for the
popup menus, so make this function virtual and document it to indicate
that it is now part of the public API.

Simplify things by putting setup.h files themselves under version
control and getting rid of setup0.h ones.
The initial motivation for using separate setup0.h files was to allow
having local changes to setup.h, but with Git there is a simple way to
do it by using "git update-index --skip-worktree include/wx/msw/setup.h"
for example, so we don't really need setup0.h any more and dropping them
makes things simpler.
A single line MSW wxTextCtrl created with a value too long to fit into
it continued showing the value only partially even if its size was
subsequently increased to allow the entire value to be shown.
This apparently happens because changing the native EDIT control size
doesn't affect its (horizontal) scroll offset. Moreover, there doesn't
seem to be any way to explicitly tell the control to update it neither,
except for changing its text.
So do change its text every time its width changes, as long as it is not
visible (because visible jumps in the visible text position could be an
even worse problem than the one we're trying to solve here). This fixes
the originally reported bug at the cost of a bunch of extra calls to
DoWriteText() which should hopefully be not too expensive for single
line controls that don't typically contain that much text.
Closes#18268.
There is no reason to only make it protected for gcc and clang, recent
MSVS versions can also give a warning (C5204, which is disabled by
default, but makes sense to enable) otherwise.
Also remove the comment about obsolete gcc 3.4.5.
Closes#19011.

It was unexpected that using wxSizerFlags().Right().CentreVertical()
didn't right-align the item because CentreVertical() reset the alignment
in the horizontal direction rather than just setting it in the vertical
one, so change this, document the new behaviour explicitly and add a new
unit test checking for it.
Closes#18989.
As we still support C++98, don't use G_VALUE_INIT as the initializer:
it's a braced-init-list, which is only allowed in C++11.

Get rid of ms_isInitialized as it must be kept synchronized with
ms_loaderDll.IsLoaded() anyhow, and it's simpler to not have it at all
rather than ensuring this.
Also ensure that calling Initialize() again, after doing it first
unsuccessfully, doesn't assert because ms_loaderDll is already loaded,
by only leaving it with a valid handle if the initialization succeeded.
Closes#19041.
wxGtkValue class was added back in 3f84cb17ca (Add wxActivityIndicator
control., 2015-03-06), but somehow never used. Start using it now
(better late than never...) as it makes the code simpler, shorter and
more robust.
No real changes.
This macro replaces the deprecated __Verify_noErr defined in the SDK.
It is different from assert, as the expression given to the macro is
always evaluated and then, if the result is not zero, and asserts are
on, an assert containing a human readable message with the description
of the error code is triggered.
Closes https://github.com/wxWidgets/wxWidgets/pull/1973
