The first attempt to add the wxEVT_STC_AUTOCOMP_SELECTION_CHANGE event to wxSTC
passed the data needed for the event through the constructor for the
wxSTCListBox class. Instead of mdifying the constructor for wxSTCListBox, it’s
better to store the data in the wxSTCListBoxVisualData class with accessors for
setting and retrieving the data.
The current wxSTC documentation page currently has a bare listing of the
event types defined for wxStyledTextEvent. These event types are
completely documented on the wxStyledTextEvent page. However the bare
listing on the wxSTC page can lead to the conclusion that there is no
documentation for the event types.
Remove the bare listing from the wxSTC page and replace it with a
referral to the wxStyledTextEvent page. This is consistent with other
large classes such as wxGrid and wxRichTextCtrl that separate the
documentation for their methods and events.
On macOS, the autocompletion popup maintains a pointer to its parent
control since it sometimes needs to set a cursor on the control. However
when the control is destroyed while the popup is active, the control is
destroyed before the popup because of the delayed destruction used by
the popup. This leaves the popup with a dangling pointer and can lead to
crashes.
To prevent this, let the popup handle the window destroy event for the
control. Reset the pointer to NULL in that handler so that the popup
will no longer try to access its parent control after it is deleted.
The SCN_AUTOCSELECTIONCHANGE notification was added in Scintilla 4.0 to
notify an application when a new item is selected in an autocompletion
or user list. However the version of Scintilla currently used is 3.7.2,
so this potentially useful notification is not available.
These changes allow an event corresponding to this notification to be
generated completely in the wxWidgets portion of wxSTC. If the Scintilla
library is ever updated to 4.0 or later, only one method should need to
be modified let Scintilla generate the event instead.
The wxSTC methods AutoCompSetColours and AutoCompUseListCtrl were added
in fe7b332b7b to allow some configuration
of the autocompletion popup window. Based on subsequent discussion, it
was decided that a better method of configuring the popup and getting
information about the configuration is needed. For now, simply remove
the current methods while the better solution is created.
In addition, since the configuration options are being removed, set the
popup to have the appearance of a list control since that was the
appearance before any configuration options were added.
* Copy-paste the code for OnChar in the wxTextCtrl.
* This implements two features:
1. This adds support for the wxTE_PROCESS_ENTER style.
2. Support for pressing the default button in a dialog if there is one.
* Use the same code as for wxNSTextField (copy-pasted).
* This method is used to redirect the enter key event to the OnChar
event.
* This makes it possible to implement the default button activation by
pressing the enter key (for comboboxes which doesn't have the
wxTE_PROCESS_ENTER style).
* It is the same as the code in the implementation of the wxTextCtrl, I
guess this could be extracted in a common function, but I don't know
where to put it.
In the class description mention that in addition to RGB, an alpha value
is stored as well. Remove incorrect description of operator=(), clarify
meaning of "on" parameter in MakeMono(), and make few minor text edits.

If the window has no valid font, GetFont() returns a temporary font.
Extend this font lifetime, so the HFONT remains valid till the end of
the function.
Using the window DPI resulted in returning a twice bigger size in points
than the size really used for the windows on high-DPI monitors as,
apparently, RichEdit always uses DPI of 96 internally (tested with both
wxTE_RICH and wxTE_RICH2 in 192 DPI under Windows 10.0.16299.785).
This will be useful elsewhere too and makes SetFractionalPointSize()
implementation less fragile as we don't have to be careful about
changing pointSize member before setting lf.lfHeight any more.
These functions are not really useful as converting between wxFont and
LOGFONT can be done trivially by passing via wxNativeFontInfo and, in
fact, wxCreateFontFromLogFont() managed to do the conversion wrongly by
forgetting to update wxNativeFontInfo::pointSize member when changing
wxNativeFontInfo::lf.
This fixes one unit test failure after the latest changes, although not
yet the other one, see the upcoming commit for this.
Free() is already called from wxFontRefData::SetFractionalPointSize(),
so there is no need to call it from wxFont too and doing this makes this
method gratuitously inconsistent with all the other setters.
No real changes.
This function is a just a very thin wrapper for WM_SETFONT, but it's
still better to have it rather than write casts to WPARAM and
MAKELPARAM() in several different places.
Note that this removes the assert for font validity from
wxWindow::SetFont() which really doesn't make much sense (and if we
wanted to have it, it would be better to have it for all ports in
wxWindowBase instead) and was never triggered since more than 20 years
of its existence.
The "Native" menu item actually only toggled drawing native-lookalike
labels, but didn't use wxHeaderCtrl as could be expected. Rename the
existing menu item to "Native-like" and add the new "Native" one which
really enables the use of wxHeaderCtrl.
Scrolling the item into view to make it visible didn't work since the
changes of badf6bc300, which suppressed
scrolling completely while frozen, any longer.
Work around it by remembering the item to make visible and actually
doing it when the control is thawed.
Also add menu item to call Freeze()/Thaw() on wxTreeCtrl in the sample
to make testing this and similar problems easier.
Closes#18435.
This class seems to be implemented in all the major ports, so remove
note saying that it supports dragging files from the applications only
under MSW.
Closes#18437.
With the generic hint support (used in pre-Vista wxMSW, wxGTK2, ...),
defining a wxEVT_TEXT handler not skipping the event completely broke
the control functionality as it was cleared, i.e. replaced the
user-entered text with the hint, whenever it lost focus.
This happened because wxTextEntryHintData::OnTextChanged() was never
called in this case, as the user-defined wxEVT_TEXT handler preempted
it. Work around this by pushing an event handler to the front of the
window event handlers chain instead of just binding to the window events
directly -- this could still potentially result in the same problem if
the user code pushes their own event handler, but this should be much
more rare and, in any case, there is not much we can do about this (the
only solution would seem to be to modify all platform-specific code to
update wxTextEntryHintData explicitly whenever the text changes).
This function is almost exclusively called from IsLevelEnabled() which
doesn't get inlined (at least by MSVS) when wxString is passed by value
to it, and so had to be updated to take a const reference instead, which
means that a copy is always going to be made anyhow, so don't try to be
smart and avoid it -- it doesn't work anyhow and just results in unusual
code, requiring explanatory comments (not needed any longer) and
upsetting static code analyzers.
No real changes.

Tick marks were not available for wxSlider under GTK+ 2 or GTK+ 3
implementations of wxWidgets. However, tick marks have been available
for the GtkScale widget since GTK+ 2 version 2.16.
This change adds similar functionality in relation to tick marks
as was already available in wxMSW builds.
Closes https://github.com/wxWidgets/wxWidgets/pull/1355
Document the discrepancy between constructing wxGCDC from
wxGraphicsContext directly or default-constructing it and calling
SetGraphicsContext() later.
Current behaviour is somewhat inconsistent, but useful, because it
allows to draw on wxGraphicsContext using wxDC API using any kind of pen
and brush, even those not supported by this API, while remaining
backwards-compatible (i.e. we can't change SetGraphicsContext() to not
re-apply font, pen and brush, as this would break any existing code
relying on this happening), so it seems like the best alternative.
The changes of ae2cb7d347 resulted in
transformation matrix not being initialized correctly any more.
Fix this by adding yet another helper, DoInitContext(), called both when
initializing wxGCDC using an existing wxGraphicsContext in the
corresponding ctor and the just created one in the other ones.
Closes#18429.
