Define g_signal_handlers_disconnect_by_data() if it's not available,
i.e. when using glib older than 2.32 where it was added, to fix the
build under old systems such as CentOS 6 broken by the changes of
8278f7b618 (see #18084).
Also use it elsewhere instead of g_signal_handlers_disconnect_matched()
as it's more readable.
Closes https://github.com/wxWidgets/wxWidgets/pull/760
The custom scheme handling implementation had been inherited from the
original WebKit1 implementation. It attempted to intercept navigation
and resource load requests and then inject the resources. It seems that
this method doesn't work in WebKit2, but fortunately, there is native
support in WebKit2 for custom URI schemes through the
webkit_web_context_register_uri_scheme() API.
Also extend wxGtkError to allow creating it from an existing GError
object as a side-effect of these changes.
See https://github.com/wxWidgets/wxWidgets/pull/716
The code was more complicated than necessary, with the base class
providing both virtual GtkOnCellChanged() and GtkOnTextEdited() that
were both overridden to achieve the same thing, namely customizing how
the value entered by user is converted to wxVariant, in different
derived classes.
Make GtkOnTextEdited() non-virtual and remove GtkOnCellChanged()
completely and add a new simple GtkGetValueFromString() which is called
from GtkOnTextEdited() to do the conversion.
This removes the existing code duplication and will make it simpler to
modify this code in the future, without changing the behaviour.
Make GTKHandleFocusOut() virtual and override it in wxChoice in order to
avoid generating wxEVT_KILL_FOCUS events when the combobox dropdown
button is clicked.
This is important because it allows fatal problems when using a
combobox-based in-place editor in wxDataViewCtrl as getting these events
totally broke the UI before.
See #17034.
Doing two different things in the same class, using m_isDynamicCompleter
to determine which kind of completion is used, was not very clear, so
create two simple classes each of which does one and one thing only and
create the one we need in wxTextEntry methods.
Note that wxTextAutoCompleteDynamic can assume to always have a valid
wxTextCompleter as otherwise no wxTextAutoCompleteData is needed at all,
which results in more simplifications.
There should be no changes in behaviour.
This allows to avoid initializing the variables to 0 in all the
overloaded ctors: wxSize default ctor already does it.
It's also more convenient to use GetScaledSize() rather than assigning
m_width and m_height separately, even if the rest of the code is broadly
unchanged.
We can reuse another ctor taking wxWindow* instead. Although this does
require an ugly cast, it's more explicit than just passing 0 which
could, in principle, match both the ctor taking wxWindow* and another
one taking double, and so is still preferable.
This is similar to the previous commit and is done for the same reasons:
screen DC needs to use the same DPI as the screen itself, instead of the
default Cairo 72 DPI.
For wxDC associated with a window, such as wx{Window,Client,Paint}DC,
this method should return the window PPI, not the hard coded 72 DPI of
Cairo graphics context.
This still doesn't work correctly when using multiple monitors with
different DPI settings, but is still a (modest) improvement.
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.
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.
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.
Don't request touch event generation for all windows by default, this
has an inherent overhead and is not needed for 99% of the application
windows, so require calling EnableTouchEvents() explicitly to do it
instead.
Note that this requires properly initializing gesture recognizers in
wxOSX now that they're not always allocated, otherwise releasing them
when destroying the window would crash.
This is a first step towards enabling gesture events only for the
windows that are interested in them as it will make it possible to avoid
wasting space on unused data in the windows that don't need it.
No real changes so far.
So wxNO_BORDER works with other controls, such as wxBitmapButton.
Also use GTK prefix on ApplyCssStyle(), and add an overload that
creates the GtkCssProvider.
FcConfigAppFontAddFile() that we use is only available since 2.8, so
check for at least this version of the library in configure.
Also change the macro guarding its use to the more semantically
appropriate "wxHAVE" rather than "wxUSE" and make it more precise by
adding "2_8_0" suffix to it.
wxFont::AddPrivateFont() can now be used to load a font from a file for the
applications private use. Update the font sample to show this.
Closes#13568.
This method was already provided by wxGTK and wxMSW, but not wxOSX nor
any other ports.
Provide a stub for it in wxWindowBase to allow user code to call it on
all platforms, there is no harm in that even if it doesn't (and can't)
do anything under macOS.
The wxGTK implementation uses wx{File,Dir}Button, which derives from
wxButton, but is not a GtkButton, so many operations which try to modify
it, such as changing it's style, are likely to result in errors.
See #17984
This helper function runs a JavaScript script and blocks until it
finishes executing, so try to use a name at least hinting at this
instead of being totally generic and useless.
Include wx headers using quotes, not angle brackets.
Wrap over long lines.
Don't put space between the function name and its arguments.
Make wxJSStringRef::ToWxString() itself, not its return value, const.
Improve comments.
Provide native implementation of this function instead of using the ad hoc one
in common code, which didn't really work -- so remove it completely now.
Closes#17189.
