Set wxDidCreatePaintDC to true even if we reused a cached wxPaintDC.
Reusing a cached wxPaintDC should count as painting the window, otherwise we
could call DefWindowProc(WM_PAINT) if WM_PAINT was generated from inside
EVT_PAINT handler (e.g. by calling wxWindow::Update()) and this validated the
entire window and no painting was really done.
In particular this fixes redrawing of wxStyledTextCtrl which does call
Update() (completely unnecessarily AFAICS) from its EVT_PAINT handler when it
wants to fully refresh itself.
This method can be overridden to customize the previously hard-coded handling
of the case when a file selected from the MRU menu doesn't exist any more: we
used to always remove it from the file history completely. This may, however,
be inappropriate and, in fact, probably never, or very rarely, is the right
thing to do when the file that we failed to open still exists.
So never remove the file from the MRU if we failed to open an existing file
(also don't give an error about it as it should have been already given by
CreateDocument()) and, while we still do it for the non-existent files, allow
to override this behaviour by overriding the new OnMRUFileNotExist() method.
Allow passing the error value to wxStreamBase::Reset().
It can be useful to induce an error on the stream explicitly, e.g. because an
incorrect value was read from it and we want to indicate it to the caller by
setting stream error to wxSTREAM_READ_ERROR.
Allow to do this by passing an optional error value to wxStreamBase::Reset().
Add an example of using the new functionality to the docview sample which
needs it to be able to signal errors while reading the files.
Also document this method that previously wasn't documented at all.
Don't pass spin text control messages processed at wx level to Windows.
Windows messages handled at wx level shouldn't be processed again at Windows
level but we always passed the events forwarded by spin control "buddy" text
window to its default window proc as we had no way to determine whether they
were really handled or not.
Now we do have a way to do, by using the newly added MSWHandleMessage(), so
only pass the messages to default window proc if they hadn't been handled
already.
This notably suppresses the annoying beep which happened if Enter key was
pressed in a wxSpinCtrl with wxTE_PROCESS_ENTER style (as used by the
corresponding wxDataViewCtrl renderer, for example). It probably corrects some
other bugs/discrepancies with the other ports in event handling in wxSpinCtrl
too.
Refactor wxWindow::MSWHandleMessage() out from MSWWindowProc().
This commit just refactors the code without changing anything in its
behaviour and will be followed by the real changes in the next one.
The new function just handles the message, without calling MSWDefWindowProc()
if it wasn't handled. This allows to call it and determine whether the message
was really handled and only continue processing it if it wasn't.
Notice that while in theory this shouldn't be necessary because the return
value of MSWWindowProc() should indicate whether the message was handled or
not (0 meaning that it was, for most messages), in practice it doesn't work
because many standard controls window procs return 0 even for message they do
nothing with, e.g. "up down" control always returns 0 for WM_CHAR messages
even it it only really handles the arrow keys.
The row_draggable callback could blithely delete m_dragDataObject twice as it
didn't reset it to NULL after deleting it the first time. Then, if the object
wasn't changed in the meanwhile, e.g. because dragging was not allowed for
this item, it tried to do it again when called the next time resulting in a
crash.
Fix drawing of expander columns not at 0 position in generic wxDVC.
The drawing code in the generic version of wxDataViewCtrl incorrectly supposed
that the expander column was always at position 0. This resulted in the
expander column not being drawn at all if it was not really the first one.
Fix the test to use wxDataViewCtrl::GetExpanderColumn() to correct this.
Correct test for maximal row index in generic wxDataViewCtrl.
The comparison in EVT_CHAR handler was incorrect for an empty control without
any rows as it subtracting 1 from 0 resulted in UINT_MAX and not -1 as all the
values were unsigned.
Fix this by checking that the new row is valid instead, this is correct for
both signed and unsigned values.
Don't set focus to a hidden window in our focus management code, this never
makes sense and results in apparent focus loss.
It also fixes, as a side effect, a crash in wxGrid under wxMSW as the focus is
not restored to the hidden grid editor any longer and so the code in its
wxEVT_KILL_FOCUS handler that resulted in the crash is not executed any
longer, see #13349.
Reset negatable switches correctly in wxCmdLineParser::Reset().
The "negated" flag of wxCmdLineOption struct was not reset by Reset() so
parsing a command line with a negatable option once influenced the result of
parsing it the next time because the old value was kept.
Do clear it now to allow calling Parse() several times without side effects.
Don't use template member function in drawing sample to placate VC6.
VC6 can't instantiate member template functions so get rid of it and use ugly
dynamic casts in the non-template function to construct wxGCDC correctly.
Fix harmless gcc warning about uninitialized mask in PNG saving code.
The mask was actually only used when it was initialized (or, conversely, the
mask was always initialized when it was used) but gcc doesn't seem to notice
this and still warns that mask components "may be used uninitialized in this
function".
Suppress the warnings by always initializing the mask, even if we don't use
it.
Refresh the old current row when right clicking in wxDataViewCtrl.
the generic implementation of wxDataViewCtrl left the old current still
focused after selecting another row as current when it was right clicked.
Fix this by refreshing the previously current row after unfocusing it.
Fix deleting columns in wxGridStringTable with custom column labels.
We erroneously removed too many elements from m_colLabels array (basically we
always removed all the elements remaining after this column, irrespectively of
the actual number of columns to delete), fix this by removing at most the
specified number of columns -- or possibly less if the array isn't entirely
filled.
Allow saving the drawing sample canvas to a file or clipboard.
This allows to test wxMemoryDC and, under MSW, wxMetafileDC and also can be
used to compare the output of different versions of the sample (possibly from
different ports, too).
Fix keyboard navigation in wxGrid with hidden columns.
The hidden columns (i.e. those whose size was set to 0) should be skipped when
find the previous/next column to select when the user presses Left/Right
cursor arrow keys in wxGrid, otherwise the focus could completely disappear as
it was invisible when it was set to a hidden column.

Better sizing in wxDataViewSpinRenderer and wxDataViewChoiceRenderer.
Their GetSize() method used hardcoded size of (80,16). Instead, use
GetTextExtent() to compute the size from content, as should be done. Add
some extra room for editor control's extra parts. The space needed isn't
computed exactly, as that would be quite convoluted (and in the end,
most likely not 100% accurate even then), using a simple approximation
instead.
Use native hint wxTextCtrl support in wxSearchCtrl.
Instead of using broken emulation of the support for hints available in the
text control, use the real wxTextCtrl::SetHint() for SetDescriptiveText()
implementation in the search control.
This looks better and, more importantly, fixes the bug when searching for the
string equal to the current descriptive text searched for an empty string
instead.
No real changes, just make some wxSlider members local variables.
wxMSW wxSlider implementation stored the min and max labels widths as fields
of wxSlider object for some reason even though they were only used in one of
its methods (and can be easily computed anyhow).
Make them simple local variables instead and also rename an existing local
variable which started conflicting with their new names.
Don't handle "Return" key as "TAB" even when the default button is disabled.
wxMSW used to handle VK_RETURN in the same way as VK_TAB if it wasn't consumed
by the default push button but this didn't correspond to the native platform
behaviour which considers pressing Return when the OK button is disabled an
error and audibly notifies the user about it.
Fix this by passing VK_RETURN to IsDialogMessage() if we don't translate it to
a button click.
Also add a possibility to test what happens when the default (or all)
button(s) in the dialog are disabled to the dialogs sample.
Use the correct event handler in wxMenuBase::UpdateUI().
Use GetWindow() instead of GetInvokingWindow() to send the event to the
associated window for the menus that are part of the menu bar and not only the
popup ones. This was broken since r64127 because GetInvokingWindow() is now
only used for the popup menus.
Support float, double and file name values in wxGenericValidator.
Currently these values can only be read from/written to wxTextCtrl but support
for other controls (e.g. wxSpinCtrlDouble for float/double) could be added in
the future.
Check for GTK window parent, not wx one, when reparenting.
A notebook page removed from its notebook can have a non-NULL wx parent but
not have any parent at GTK level any longer, so test for the window parent at
GTK level before removing the widget from it, otherwise we were getting GTK
asserts when trying to remove a window from its no-more-parent.
Refresh the generic wxDataViewCtrl header if it was made too small.
Although normally the control header is not supposed to be resized below its
minimal vertical size, sometimes this can still happen and in this case ugly
artefacts were displayed because it wasn't refreshed properly. Do refresh it
to avoid them.
Output something from the console sample even if it's ran without arguments.
Running console sample without parameters didn't do anything by default and
didn't output anything neither which was presumably rather confusing. Do
output a welcome message at least to indicate that something happened.
Immediately update MSW cursor when ::SetCursor(wxNullCursor) is called.
The cursor was previously reverted to the default one only when a next mouse
event was received. Do it immediately now to e.g. avoid showing the busy
cursor when the program is not busy any more.
Fix wxMSW wxSlider best size calculation and label layout.
The best size calculation was wrong as the min/max labels height was
unnecessarily added to the slier total height even if though these labels are
positioned alongside the slider itself in horizontal layout case.
The slider also managed to position its value label completely outside the
space allocated to it (and the bug in DoGetBestSize() might have been an
attempt to work around this), don't do this any more. This also fixes the
wrongly centered vertical position of the min/max labels.
Make coordinates transformations in wxDC really maximally precise.
Use the maximal device space extent supported by Win32 GDI and only decrease
it if the scale is so small that keeping the device space extent maximal would
result in overflowing the int range for the logical space.
This makes coordinate translations exact even for huge coordinates, while they
could be significantly wrong before due to the integer rounding errors.
We finally didn't switch to using the standard containers by default so don't
leave misleading information in the change log (this should have been part of
r67735).
Fix warnings about implicit double to int conversions in propgrid.
Use wxRound() instead of implicit casts to convert double to int. This not
only avoids warnings (e.g. when using g++ with -Wconversion) but also should
be (marginally) more precise.
Fix crash in wxDataViewProgressRenderer in non-Unicode build.
We can't use the column pointer in wxDataViewProgressRenderer ctor as it's not
set yet, so postpone setting the renderer label until later in non-Unicode
build which needs the font used by this column to do the conversion to UTF-8.
Add wxCOMPOSITION_INVALID mode and use it to simplify the code.
Having an invalid element in wxCompositionMode enum allows to directly return
it from TranslateRasterOp() function instead of needing a separate bool
parameter to indicate that a ROP couldn't be translated.
This also incidentally fixes warnings about possibly uninitialized variables
in optimized g++ builds.
Avoid g++ warnings about breaking strict aliasing rules in wxTreeCtrl.
The standard TreeView_GetItemRect() macro resulted in warnings about breaking
strict aliasing rules as it passed a variable of one type via a pointer to
another one. Fix this by using a union and our own custom macro instead.

Initialize variable in UTF{16,32} conversion code to avoid warnings.

Work around bogus g++ warnings about possibly missing return.

Change the loop condition to avoid comparing unsigned value with 0.
This resulted in (useful) g++ warning and didn't make any sense in any case.
Check for the loop variable value being 0 at the end of the loop instead now.
If the old code was correct it shouldn't change its behaviour and if not, this
might fix a bug.

Always initialize SelectInHDC::m_hgdiobj in wxMSW.
Leaving m_hgdiobj uninitialized probably didn't result in any problems
considering how this class is currently used but it did result in g++ warnings
about uninitialized member with aggressive warning flags and also could easily
become a problem in the future so just ensure that we always initialize it.
