Merge ctors from (width, height) and (width, height, scale) into a
single one because the former really should be just a special case of
the latter for scale == 1 but, surprisingly and confusingly it wasn't,
because the latter also multiplied the size by scale, meaning that width
and height parameters had different meanings.
This resulted in at least 3 bugs when using scale factors different from
1: first, copying bitmaps wasn't done correctly because as
wxBitmapRefData copy ctor incorrectly scaled its size by scale again.
And second, creating bitmap from wxImage whose size wasn't divisible by
scale not just didn't work correctly but crashed when accessing memory
outside of the image because (unnecessarily) dividing and multiplying
the image size by scale wasn't idempotent. Finally, even for the images
of even size (assuming scale factor of 2), bitmaps created from them
used incorrect width and height, corresponding to the half of the image
dimensions, instead of the same ones, as they're supposed to be (the
scaled dimensions are supposed to be returned by GetScale{Width,Height}
methods).
Closes#17505.
Several compilation fixes due to the fact that sizeof(long)==8 under
Cygwin in 64 bits.
This allows the library to compile, but there are still run-time
problems, notably the unit tests throw an unknown exception currently.
This is another fix for 64 bit Cygwin build: LONG is defined as a 32 bit
type in it, but not long, which is 64 bits, so use the former instead of
the latter.
Due to the same problem with sizeof(long) mismatch as in the previous
commit, we can't use struct timeval, with its long fields, in 64 bit
Cygwin builds, and need to use __ms_timeval instead.
Add wxTimeVal_t type to hide this difference and update all code
compiled under MSW (there is no need to uglify Unix-only code using
timeval, as in wxSelectDispatcher, for example) to use it instead of
timeval.
Use __LONG32, which is always 32 bits when using Cygwin, unlike long,
which is 64 bits there in 64 bit builds, and so can't be used as an
argument to InterlockedExchange().
Closes#16746.
In some specific scenario, described in the newly added comment in
wxStaticBoxBase::Enable(), the box and its label could remain disabled
after its parent was disabled and re-enabled.
Fix this by continuing to use the derived class version for disabling
the box children, but not when enabling them, as the base class version
already does the right thing in this case.
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.
Simplify the code by replacing 2 conditionally-compiled DoEnable() calls
with a single unconditional one.
This doesn't change the behaviour of Enable(), as it always called
DoEnable() on the window itself and only did it for its children when
wxHAS_NATIVE_ENABLED_MANAGEMENT was not defined before and continues to
do the same thing now, but it should fix a small bug in Reparent() as it
didn't update the actual status of the window if it changed as the
result of reparenting before, even though it was supposed to.
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 reverts commit d26758044c which was a
workaround for the problem of wxWakeUpIdle() dispatching events, as this
is not the case any more after the latest changes.
It just forwards to (virtual) WakeUp() and there should be no need to
ever override this method itself (nor even to keep it, except for
backwards compatibility).
No real changes.
Since the switch to using an event object for idle handling wakeup,
WM_NULLs are not being sent any longer, so wxIdleWakeUpModule didn't do
anything, resulting in pending event dispatching being paused while our
event loop was not running, as it happened, for example, while the
window was resized.
See #17579.
This reverts commit ebb3a791b9,
effectively reapplying 6c40531fb7 once
again.
This breaks wake up when not running our own event loop once again
(see #17579), but this will be fixed in the next commit.
This can result in deadlocks because wxWakeUpIdle(), admittedly rather
unexpectedly, can result in dispatching a message in the main thread,
which could reacquire the same lock again.
Allow specifying label="1" attribute in wxRadioBox <item> tags to
indicate that the usual translation of "_" to "&" should be done, as for
all the other labels.
This is still not the default behaviour to avoid breaking any existing
XRC files using "_", even though using labels="1" by default would make
more sense.
Translate all strings in the new GetNodeText() function replacing the
old GetText() which was mostly used for translatable strings before --
except that <item> tag contents didn't use it because it also performed
string unescaping, not wanted for the control items, in addition to
translation.
Replace the old GetText() (while still keeping it for compatibility,
i.e. to avoid breaking any custom XRC handlers using it) with the new
function which is more flexible and can be used for all tags.
No real changes, this is just a refactoring.
Extract styles initialization into a function reused by both
wxSpinCtrlXmlHandler and wxSpinCtrlDoubleXmlHandler.
No real changes, this is a pure refactoring.
Override SetWindow() to check that the validator is being associated
with the window of the correct type, this allows to trigger an assert
immediately if this is not the case, making it simpler to find the error
as the call to SetValitator() on the wrong window will be in the call
stack when this happens, unlike before when the assert would happen only
at some later time.
Allow overriding the method called when the validator is associated with
the window, this can be convenient to perform some initialization on the
validator instance actually used as it can't be done on the initially
created object itself because it will be cloned by SetValidator(),
creating a new instance.
Also change SetWindow() to take wxWindow instead of wxWindowBase, this
still requires the cast in wxWindow::SetValidator(), but it's better to
have it there rather than in wxValidator and use the simpler type in the
public function signature.
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).
Allow specifying arbitrary windows as labels for the static boxes
created from XRC.
Note that wxStaticBox XRC handler itself wasn't updated to support this,
as this handler seems to be quite useless because it's impossible to
define any box children with it, so only wxStaticBoxSizer XRC handler
really matters, anyhow.
Using GtkBin as widget parent didn't work without overriding its
size-related vfuncs until GTK+ 3.8 and, in particular, resulted in the
editor (which was the child of the bin) not being visible at all with
GTK+ 2.
Switch to using GtkHBox as parent, which does work with both GTK+ 2 and
any GTK+ 3 version, but keep using GtkBin with GTK+ 4 as GtkHBox is
removed in it.
This fixes bug introduced in c2821dcea0
since which custom wxDataViewCtrl editors were not visible any more.
Closes#17686.
No real changes, just don't call gtk_wx_cell_renderer_get_size()
unnecessarily as we never use its result: the code using the returned
rectangle was commented out ever since it was added (more than 10 years
ago) in 1e510b1e2d
No real changes, just don't define macros that we never use and don't
plan on using it (why would we need to test whether something is of this
type when we already know it).
While it seems to be harmless in this particular case, it still prevents
testing this code with UBSAN by triggering it here, so check that
multiplication doesn't overflow.
Don't divide by waveformat.uiBlockAlign which could be 0, but rather
multiply by it and verify that we get the expected result. This is more
robust, as it prevents crashes on malformed input and also slightly more
efficient even for correct input.
Check that we have enough data in the input instead of happily reading
out of bounds memory.
This fixes the most common problem of crashing on bad data which doesn't
look like WAV at all, but doesn't fix problems with parsing input which
does look like WAV, but is incorrect -- this will be done in subsequent
commits.
This is a micro-optimization, as pre-increment is at least as efficient
as post-increment and typically slightly more so because it doesn't need
to make a copy of the iterator, and better conforms to the prevailing
C++ style.
Closes https://github.com/wxWidgets/wxWidgets/pull/655
We need to explicitly generate this event from the char hook handler as
we don't get the normal WM_CHAR for it, it is apparently intercepted by
the window proc installed by the auto-completing code, so check if
wxTE_PROCESS_ENTER is used for the text entry and call a special new
MSWProcessSpecialKey() method to do the right thing if it is.
Similarly, handle Tab presses correctly if wxTE_PROCESS_TAB is used.
Closes#12613.
If we don't pass these messages to it, the selected items highlight
rectangle doesn't get updated when the columns are resized when using
visual themes, as could be seen in the listctrl sample.
While this did work if the wxEVT_LIST_COL_DRAGGING event handler skipped
the event, prefer to not require doing this as things work without this
call to wxEvent::Skip() under the other platforms and even MSW with
themes disabled.
Closes#18032.
