Trying to be smart by setting m_isEnabled to false in
wxStaticBox::Enable() without actually disabling the box itself (because
it can't be done if its label window is to remain enabled) didn't really
work. For example, it was impossible to TAB to a checkbox label of the
box when it was disabled, because keyboard navigation (correctly)
doesn't recurse into disabled windows and there could be similar
problems with any other code iterating over windows and skipping over
the disabled ones.
So, finally, simplify things and keep m_isEnabled in sync with the real
box state, even if this, counter-intuitively, means that IsEnabled() on
the box returns true after calling Enable(false) on it.
This also reverts 4ee35cf5ee569b6ee6c7d0d5702484d4d2a20f96 ("Don't
disable wxStaticBox children at wx level when disabling it") as we can't
avoid really disabling the children any more now that their parent is
not disabled: without this, their IsEnabled() would return true, i.e.
they wouldn't be disabled at all, from the program point of view. This
is unfortunate for the reasons that originally motivated that commit,
i.e. if some wxStaticBox child is disabled, disabling and re-enabling
the box will now re-enable this child, even if it shouldn't, but seems
impossible to avoid. The only possible alternative is to modify
IsEnabled() to add some wxStaticBox-specific hook to it, e.g. instead of
calling GetParent()->IsEnabled() there, we could call some now
AreChildrenEnable() method, which would delegate to IsEnabled() by
default but overridden in wxStaticBox. However this seems complicated,
and will add an extra virtual function call to all (frequently
happening) IsEnabled() calls.
Calling Enable() on all children from wxStaticBox::Enable() was wrong,
the actual status of the child, returned by wxWindow::IsThisEnabled(),
is not supposed to change just because its parent was disabled.
Call NotifyWindowOnEnableChange() to avoid this, while still disabling
the children visually.
There doesn't seem to be any need to have this symbol in the header,
when it's only used in NotifyWindowOnEnableChange() in wincmn.cpp.
No real changes.
This behaviour might be not completely intuitive, but it makes it much
simpler to handle the box state using a checkbox as the label control
(which is by far the most common case of using box window labels).
Notice that while we could add a separate EnableWithoutLabel() method to
wxStaticBox to make it possible to set the state of the box directly
relatively easily, it wouldn't help with using wxEVT_UPDATE_UI for
managing the box state indirectly as it relies on calling Enable() only.
And this solution does allow wxEVT_UPDATE_UI handlers for the box itself
to work (provided the handler takes care to check for the event object
being the box itself, as otherwise it would still disable the child
checkbox when its wxEVT_UPDATE_UI bubbles up to the box).
Inherit from wxCompositeWindowSettersOnly<> to make sure all the usual
setters, such as SetForegroundColour() and SetFont(), called on
wxStaticBox are propagated to the label window too.
However also prevent SetBackgroundColour() from being propagated
unnecessarily -- because the checkbox already inherits the parent
background colour by default in wxMSW anyhow -- and still override
SetFont() to adjust the label window position after the font change,
otherwise it could be truncated after increasing the font size, for
example.
Because of these issues, wxCompositeWindowSettersOnly is not ideally
suited for its use here, but on balance it still seems to be better to
use it rather than reimplement parts of its functionality here.
Extract this class from wxCompositeWindow, as sometimes it can be
convenient to just define the setter functions to do the right thing for
a window containing sub-windows, but without dealing with focus too.
This will be used in wxMSW wxStaticBox in the next commit.
As this class is only supposed to be used as a base class, its ctor
doesn't need to be, and hence ought not to be, public.
Also update an outdated comment stating that the ctor didn't do anything
when it, in fact, does perform an important task.
Remove wxSIZE_AUTO from the SetSize() call, this was completely
unnecessary and unexpectedly (and wrongly) resized composite windows
managed by sizers as SetLayoutDirection() side-effect.
This allows to call the protected wxWindowGTK::DoApplyWidgetStyle()
method when it's really necessary, e.g. when forwarding to it from
DoApplyWidgetStyle() implementation for another window.
Factor out the code from wxStaticBoxSizer dtor into a wxStaticBox method
to improve encapsulation: the static box knows better than another class
how to detach its children from it before destroying it.
No real changes yet.
MSVS 2017 (which uses _MSC_VER from 1910 to 1912 currently) is
ABI-compatible with MSVS 2015 (_MSC_VER 1900), so do allow linking code
compiled with one of them with the library built by the other one.
Closes#18024.
Do not use 'RADIO_SIZE 20' as the fixed width of the radio button, but use the actual width as returned by wxRendererNative.
wxRendererNative has no GetRadioButtonSize, so for now use GetCheckBoxSize. It returns the same sizes.
Also add a half character width to account for the space between the button and the label.
There is no need to add extra width to the label of the static box.
Closes#18010.
Add wxMSWWinStyleUpdater and wxMSWWinExStyleUpdater helper classes which
allow writing code changing GWL_STYLE and GWL_EXSTYLE bits,
respectively, in a shorter and more clear way.
There should be no real changes in behaviour.
Replace the hack with resizing the control to the minimal possible size
while it's frozen with just disabling its scrollbars in the frozen
state. This should also fix the original problem (of scrollbar jumping
around wildly as the items are added), but without different problems
due to the control being resized unexpectedly.
Unfortunately we don't have a reproducer for the original problem, which
the commits 6754c300cf ("Freeze wxTreeCtrl
in wxMSW by hiding it") and 4e1e8dc51b
("Change wxMSW wxTreeCtrl::DoFreeze() to not hide the tree any more" --
but resize it instead) tried to fix, so it's difficult to be sure that
it really doesn't exist any more, but it does seem like it ought to be
as the comment added back then spoke of the problem with scrollbar
updating and this really shouldn't happen if scrollbars are completely
disabled.

It seems that MinGW-w32 started distributing GDI+ headers since this
version and MinGW-w64 might have supported them for even longer, but
it's difficult to test for the MinGW distribution used in this header,
as it is included before wx/msw/gccpriv.h which defines
__MINGW32_TOOLCHAIN__ and __MINGW64_TOOLCHAIN__ symbols and changing
this is tricky due to relative order of defining UNICODE and
wxUSE_UNICODE and including MinGW headers, which can only be included
once UNICODE is set properly.
But while the fully correct solution is difficult, just checking for the
compiler version should solve the problem in 99.99% of the cases in
practice as there should be vanishingly few people using MinGW-w64 with
gcc < 4.8 currently, so this simple solution is good enough.
Closes#17973.
Fix a copy-and-pasto in the header and also mention that wxURLDataObject
derives from wxDataObjectComposite, and not wxTextDataObject, in wxGTK
too.
Also add a note about the exact base class being an implementation
detail.
Closes https://github.com/wxWidgets/wxWidgets/pull/624
This is more convenient and less error prone than using the existing
ctor taking char pointer and length as the buffer contains both.
Also add the corresponding assign() overload for consistency.
See #16490.
Show non-printable characters when comparing strings more clearly if the
comparison fails, this is notably useful for strings containing NULs as
they were previously completely lost.
Miscellaneous fixes for time zones and DST handling in wxDateTime.
This still leaves 2 big problems:
1. We have no support for using the correct time zone offset at the
given date and always use the current time zone offset, which may,
and often is, wrong.
2. Our code for converting to/from broken down representation doesn't
handle DST at all, so support for DST is non-existent for the dates
before 1970-01-01 or after 2038-01-01 (i.e. roughly outside of the
32 bit time_t range).
See #10445 and the other tickets linked from there.
Don't rely on time zone offset to check whether it is local as this
doesn't, and can't, work for the local time zone in Great Britain which
uses the same offset as UTC, but does use DST, unlike the latter.
Add a unit test (albeit disabled by default) checking that the code that
previously didn't work correctly in BST does work now (run the tests
using "TZ=Europe/London ./test wxDateTime-BST-bugs" under Unix to test).
Closes#14317, #17220.
See #10445.
The class needs to use WXDLLIMPEXP_ADV in order for its (default,
compiler-generated) dtor to be generated inside the library, otherwise
this doesn't happen and linking code using this class inside a shared
library fails with errors due to the dtor being undefined.
This is a tiny optimization (or maybe not so tiny on platforms other
than Linux where time() might not as fast as just reading a memory
location), but mostly is done to work around faketime bug[*] which
prevented it from being used for testing programs using wxWidgets, such
as our own unit tests because time() was called from wxLogTrace() in
wxCSConv::DoCreate() called when creating global conversion objects
during the library initialization.
Arguably, it might be better to avoid calling wxLogTrace() during the
initialization, but this can't be done as simply and this change might
have a small performance benefit too.

Allow wxPrintf("%1$s %1$s", "foo") to work.
Take into account the possibility that the number of format specifiers
and the number of actual arguments can be different.
Closes#9367.
Handle this feature as all the other ones and provide a configure switch
and a setup.h option to disable it if necessary, as it may be desirable
to do it, especially under Linux, to avoid extra dependency on pangoft2
if this functionality is unnecessary.
Use wx_is_at_least_gtk2(minor) instead of gtk_check_version(2, minor)
because it is more clear and also works as expected (i.e. returns true)
when using GTK+ 3 instead of creating difficult to notice bugs in the
code by failing the version check in this case.
See #18004.
Unfortunately there is no reasonable way to implement this function for all
glibc versions as the information we need is stored in the private
_GOptionGroup struct whose layout has already changed once (in 2.44) and could
change again, so we can't rely on it.
We really need a g_option_group_get_entries() in glib itself, but the request
to add it at http://bugzilla.gnome.org/show_bug.cgi?id=431021 hasn't been
touched since 10 years, so it seems unlikely to happen.
