Using strcpy() in GetDataHere() added an extra NUL at the end which
didn't fit into the buffer of the size returned by GetDataSize(). This
could have been also fixed by returning an extra byte from the latter
function, but as the string doesn't need to be NUL-terminated,
apparently, just use memcpy() with the correct number of bytes instead.
Also, because the string is not necessarily NUL-terminated, use the
provided length in wxHTMLDataObject::SetData() instead of relying on the
buffer being NUL-terminated and reading uninitialized memory beyond its
size.
Add a unit test confirming that there are no more ASAN errors when using
this class.
Closes#23660.

Use StartFragment and EndFragment headers values in order to extract the
HTML fragment from the entire CF_HTML string, instead of searching for
"<!--StartFragment-->" and "<!--EndFragment-->" comments which could be
wrong (e.g. if a StartFragment comment actually appeared inside the HTML
fragment) and less efficient too.
Also add a simple pseudo-test, disabled by default, allowing to view the
clipboard contents if HTML is available on it.
Fix a long-standing bug in wxMSW wxTextDataObject which returned the
size including the trailing NUL from its GetDataSize() and used the same
convention in GetData(), but didn't account for this NUL being included
into the buffer passed to SetData().
This was partially compensated by also passing the wrong (too small)
buffer size when calling SetData() from wxIDataObject, but still
resulted in problems when using SetData() with the length returned from
GetDataSize(), as done in wxDataViewCtrl code.
Fix this by now always considering NUL part of the buffer (as this is
the platform convention, i.e. all CF_TEXT data on the system clipboard
must include the trailing NUL) and taking it into account when
determining the buffer size in wxIDataObject.
This change is not fully backwards-compatible as it breaks any code
calling SetData() directly, as e.g. wxURLDataObject in wxMSW itself did,
so document it as such, but it's still worth making it as there doesn't
seem to be any other way of fixing the problem described in the linked
issue and direct calls to SetData() should be rare as simpler SetText()
should be used instead.
Also add a unit test for wxTextDataObject and extend the existing test
of wxURLDataObject.
Closes#22928.
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.
Define wxDataFormat::operator==(wxDataFormatId) instead of relying on
the implicit conversion from wxDataFormatId to wxDataFormat, as this
can't be done when the format ID is wxDF_INVALID because creating
wxDataFormat results in an assert failure in this case, while comparing
with wxDF_INVALID is clearly a perfectly valid operation.
Add a unit test checking for this.
Closes#22213.
This function was defined in wxGTK and wxOSX, but not in wxMSW or the
other ports, but it can be useful there too, so make it public and
define it in common code.
Drop the legacy CppUnit testing framework used for the unit tests.
Replacing it with Catch has the advantage of not requiring CppUnit
libraries to be installed on the system in order to be able to run
tests (Catch is header-only and a copy of it is now included in the
main repository itself) and, in the future, of being able to write
the tests in a much more natural way.
For now, however, avoid changing the existing tests code as much as
[reasonably] possible to avoid introducing bugs in them and provide
the CppUnit compatibility macros in the new wx/catch_cppunit.h header
which allow to preserve the 99% of the existing code unchanged. Some
of the required changes are:
- Decompose asserts using "a && b" conditions into multiple asserts
checking "a" and "b" independently. This would have been better
even with CppUnit (to know which part of condition exactly failed)
and is required with Catch.
- Use extra parentheses around such conditions when they can't be
easily decomposed in the arrays test, due to the use of macros.
This is not ideal from the point of view of messages given when
the tests fail but will do for now.
- Rewrite asserts using "a || b" as a combination of condition
checks and assert macros. Again, this is better anyhow, and is
required with Catch. Incidentally, this allowed to fix a bug in
the "exec" unit test which didn't leave enough time for the new
process to be launched before trying to kill it.
- Remove multiple CPPUNIT_TEST_SUITE_NAMED_REGISTRATION() macros,
our emulation of this macro can be used only once.
- Provide string conversions using Catch-specific StringMaker for
a couple of types.
- Replace custom wxImage comparison with a Catch-specific matcher
class.
- Remove most of test running logic from test.cpp, in particular don't
parse command line ourselves any longer but use Catch built-in
command line parser. This is a source of a minor regression:
previously, both "Foo" and "FooTestCase" could be used as the name of
the test to run, but now only the latter is accepted.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

We need to ensure that all windows are realized before querying their
positions on screen, so add an extra wxYield().
Also adjust the tests slightly as the windows are now all created in the
beginning of the function.
Finally, use Destroy() instead of wxDELETE() for windows.

Return the deepest child of the window and not the first one as this function
needs to return the window that is at the top of Z-order.

Use ChildWindowFromPointEx(CWP_SKIPINVISIBLE) to ensure that we find the

Verify that this function (which is used for parsing the wildcard strings used
with file-related dialogs) works as expected and also asserts when given
invalid input.

The code in CFSTR_SHELLURLDataObject::GetDataHere() was confused by
ANSI/Unicode and ended up overwriting output buffer because of it. Moreover,
this function was actually completely unnecessary as the base class version
did work correctly.
Closes#11102 (thanks to Tim Kosse).
