-boundsForScreen: to get correct screen dimensions if RandR is supported.
(_OSFrameToXHints:for:): ditto.
(_XFrameToOSFrame:for:): ditto.
(movewindow::): ditto.
(windowbounds:): ditto.
(setMouseLocation:onScreen:): ditto.
* Source/x11/XGDragView.m: ditto.
* Source/x11/XGServerEvent.m (processEvent:): destroy NSScreen screens
list to be regenereated on next call. This change updates ivars of
NSScreen (_frame, _depth) by recreating NSScreen instances.
(mouseLocationOnScreen🪟): use -boundsForScreen: to get correct
screen dimensions if RandR is supported.
ivars were added.
* Source/x11/XGServer.m (_initXContext): get RandR event and error base.
* Source/x11/XGServerEvent.m (processEvent:): pack several RandR events
into one notification post.
enabled get screen dimensions using Xrandr objects.
* Source/x11/XGServerEvent.m (processEvent:): process Xrandr event and
send NSApplicationDidChangeScreenParametersNotification.
* Source/x11/XGServer.m (_initXContext): subscribe to the Xrandr event.
- use lowerCamelCase for objects and underscores for primitive types;
- added and used `this_window` variable - represents window that has
received TakeFocus event - instead of `cWin` (last used window by
backend);
- do not ignore TakeFocus request if now key window was set
and if main application menu received request.
image_mask().
(swapColors): new function to convert colors from ARGB order into RGBA
(big-endian systems) or BGRA (little-endian systems).
(_createAppIconPixmaps): use swapColors() and remove unused code.
(restrictWindow:toImage:): use alphaMaskForImage().
(imagecursor:::): use swapColors() and remove unused code.
off-by-one mistake during alpha handling. Enable disabled code and
remove temprorary one.
(window::::): set NetWM icon to window for all EWMH capable WMs even
it's WindowMaker.
(image_mask): new function to create alpha mask for image. It's based
on xgps_cursor_mask() code with additional argument `alpha_treshold`.
This function may be used for images (alpha_treshold == 0) with real
alpha mask and for cursors (if no Xcursor library is used - no alpha
is used, no shadows in cursors, alpha_treshold == 158 is used to cut
transparent pixels).
(_createAppIconPixmaps): icon pixmap creation rewritten to support
images with alpha channel using wraster functions. Use image_mask().
(restrictWindow:toImage:): use image_mask() instead of
xgps_cursor_mask().
(xgps_cursor_mask): removed as image_mask() replaced it.
Guard xgps_cursor_image( with #if - will not be compiled if Xcursor
is used.
(imagecursor:::): use image_mask() instead of xgps_cursor_mask().
to _convertToFormatBitsPerSample::::::::. Fixes display of colored
mouse cursor images.
(standardcursor::): cleanup in Xlib cursors handling. Additional
cursor types were added: GSClosedHandCursor, GSOpenHandCursor.
Removed GSDisappearingItemCursor type handling - it loads in NSCursor
from image.
and setups observer for defaults changes.
(mouseOptionsChanged:): new method. Read mouse properties from user defaults.
(processEvent:): respect mouse options on ButtonPress and ButtonRelease events.
* Source/x11/XGServer.m (dealloc): remove notification observer.
There's no good reason not to enable subpixel rendering and hinting.
Leaving it off makes GNUstep apps look worse than everything else, in
exchange for having -advancementForGlyph: be totally consistent, which
may not even be necessary.
So, yeah, let's just turn this stuff on. I reused the subpixel default
from back-art to preserve configs, and added a GSFontHinting default to
control text hinting.
Use 0 for whatever Cairo defaults to, 1 for off, 2 for slight hinting,
3 for medium hinting, or 4 for full hinting.
Some simple code for getting access to the main SFNT tables used for
drawing the right glyphs in the right ways. It's hidden with an "#if 0" for
future use.
Implement a method for accessing named glyphs and character codings from
Cairo.
This is a necessary first step for complex glyph substitution, and even
simple things like standard ligatures.
Rather than sorting fonts by the integer value of "traits", let's sort by
the traits we are looking for specifically. Again, like many other things,
totally correct handling of this stuff will have to wait for a good method
of inspecting and correctly processing SFNT tables.
Fontconfig's font weights are almost but not entirely defined by the
constants found in its source code. Things like FC_WEIGHT_LIGHT are not,
as we had presumed, a list of definitive weights. As such, it seems there
are a goodly number of fonts that have weights not appearing in the list.
For example, say there's a font that is heavier than Medium (weight 100 for
fontconfig, and 6 for us) but not as heavy as Demibold (FC: 180, GS: 7),
then it might tell Fontconfig it has a weight of 130.
When this happens, we _could_ assign its NSWeight to be 6 or 7, but it's
possible that there will be another face in that font that ALSO fits there,
which might throw off the sorting. Instead, what I suggest is to do what
I have done...assign an NSWeight with a weight class that represents the
numeric distance _between_ the two defined values.
So the GS weight for this font face becomes something like:
NSWeight = 6 + ((FCWeight - Medium) * (1.0 / (Demibold - Medium)))
or, in numeric terms, 6 + 0.375
In service of this change, I have switched the actual Weight value within
the font dictionary from int to float. This is an attempt to translate this
situation into a sortable form we can work with, compressing an approximate
range of possible FC font weights into our 0-15 system.
There may well be a better way to go about this, such as figuring out where
fontconfig gets this info in the first place and converting from the source
directly, but accessing the SFNT tables (which will almost certainly be
required) is something for a later day.
