This is not needed any longer after the changes of the last commit.
Note that the (still existent) public wxGetDisplaySizeMM() didn't use
this function, but used PPI instead.
Don't try computing the PPI ourselves from the physical size and the
number of pixels, this doesn't work and nobody else does it like this.
Just assume that we're using standard PPI by default and use
toolkit-specific functions for the platforms with support for high DPI.
There is no reason to call ::GetMonitorInfo() all the time, e.g. just to
determine if the monitor is primary, as we can just store it entirely.
We already invalidate the information stored for all the displays
whenever anything changes, so the cached information doesn't risk
getting out of sync.
Only invalidate display cache when something related to the displays has
changed and not whenever any system option has.
This should avoid completely unnecessary refreshes when a UAC prompt is
shown, for example: even if doing this works now, after the previous
commit, we still don't have to do it at all.
Passing screen HDC to EnumDisplayMonitors() doesn't work if we do it
while a UAC prompt is shown or during log-off process, so change the
code enumerating the displays to use monitor-appropriate HDC instead.
This fixes the problem with losing display information entirely if
WM_SETTINGSCHANGE was generated when showing UAC prompt, as it happens
when "automatic background color" option is set under Windows 10.
wxDisplay::InvalidateCache() does the same thing this function does, so
just remove it to avoid confusion.
This also allows to get rid of ms_factory duplicating the factory
pointer stored at wxDisplay level.
See https://github.com/wxWidgets/wxWidgets/pull/1281
Information about display cached in wxDisplayFactory::m_impls and in
wxDisplayFactoryMSW::m_displays could get out of sync after removing a
display from the system, resulting in failures when calling various
wxDisplay functions later.
To fix this, reuse InvalidateCache() to invalidate the cache in
wxDisplayFactoryMSW too, making it virtual in order to allow overriding
it there. Also call InvalidateCache() from wxDisplayFactoryMSW itself
instead of doing it from wxWindow, as this works even when the
application isn't showing any windows (and also keeps all
display-related code together).
Closes https://github.com/wxWidgets/wxWidgets/pull/1246
While this is not done for all the ports yet, the new API allows
returning different PPI values for different monitors, unlike the old
(and still existing, but implemented in terms of the new one) global
function.
Allow getting the depth of any display, not just the primary one, even
though this is not implemented for Unix ports currently.
Mostly do this for consistency with the other display-related functions.
Instead of forwarding to these functions from wxDisplay implementation
in wxUSE_DISPLAY==0 case, make the functions themselves wrappers around
wxDisplay, which may, or not, depending on the platform, have a simpler
implementation in wxUSE_DISPLAY==0 case, but is always available in any
case.
As part of this change, only use src/osx/core/display.cpp in macOS
builds, not iOS ones and update the Xcode project accordingly too.
This cuts down on code duplication, especially in wxGTK, and facilitates
further additions to wxDisplay API.
Don't define MONITOR-related structs and messages ourselves in wxMSW code,
this shouldn't be needed any more as they're present in all remotely recent
versions of the SDK.
No real changes, just minor clean up.
Windows CE doesn't seem to be supported by Microsoft any longer. Last CE
release was in early 2013 and the PocketPC and Smartphone targets supported by
wxWidgets are long gone.
The build files where already removed in an earlier cleanup this commit
removes all files, every #ifdef and all documentation regarding the Windows CE
support.
Closes https://github.com/wxWidgets/wxWidgets/pull/81
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.

Extract wxMSW-specific part of src/msw/utilsgui.cpp into a new
src/msw/utilswin.cpp file to allow reuse the rest of the former file in wxGTK.

As wxWindow doesn't have an associated HWND when using wxGTK, use
MonitorFromPoint() instead of MonitorFromWindow() for this port.

Use t_str() instead of wx_str() to make the code work correctly in UTF-8 build
in which wx_str() returns a pointer to UTF-8 buffer while we need a wchar_t
pointer for Windows.

If a monitor was attached or detached while a wx program was running, the
monitor handles stored in wxDisplayFactoryMSW became invalid and all display
operations (e.g. getting display size) failed from this moment onwards
requiring a program restart to work again.
Fix this by updating the monitor handles when we get WM_SETTINGCHANGE as it is
sent when a monitor is added or removed (while it's also sent in quite a few
other cases re-enumerating the monitors shouldn't take very long so just do it
always).

Applied patch by snowleopard2 fixing a bunch of typos such as misspellings and double words in the documentation. Combined the patch with some local queued typos waiting to be committed as well as adding new typo fixes inspired by the patch.
Function names with American spelling were not changed nor was third-party code touched. The only code changes involve some changes in strings that are translated ("Can not" -> "Cannot").
Closes#13063 (again).

Somehow MSVC 9 compiled invalid wxT(__FUNCTION__) expressions but both MinGW
and MSVC 6 (correctly) failed. Don't use this construct at all but instead
call wxLogLastError() with the real function name.
Also refactor the code slightly to avoid having to repeat this fix thrice.

Don't cache display rectangle and client rectangle as they can both change
during the program lifetime (especially the latter which changes whenever
taskbar is moved or shown/hidden) and retrieving them every time they're
needed doesn't seem to be a problem performance-wise anyhow.
We still cache the list of all the monitors, ideally we'd refresh it when we
receive a notification about a display being [dis]connected.

Remove commented out version of DirectDraw-based wxDisplayFactory

2. added template type-safe wrappers for vararg functions
