warning: ‘int xrender_supported()’ defined but not used
This happens only with certain configure options, particularly if
FLTK_USE_CAIRO is set, i.e. drawing with Cairo is enabled.

This improves reading large selections and fixes one more bug.
- Fix reading selection data size of clients that don't send the size.
These clients don't respect the ICCCM. Using a default size instead.
- Improve memory allocation by pre-allocating at least 4 MB and
extending by 4 MB to reduce the number of realloc() operations.
This may waste up to 4 MB buffer space but this is only an issue
if clients don't send an appropriate size (see above).
- Limit the initial allocation to 200 MB in case clients send higher
values. This is very unlikely and might be a bug in these clients.
Default extension as above would apply anyway.
- Add more comments and optional debug statements (commented out).
Note: reading selections (clipboard) from other clients using the
INCR protocol is implemented but the opposite (providing large
selections (clipboard) by using the INCR protocol is not.

- Fix reading the size (aka "lower bound") of selection data.
- Use Fl::fatal() to terminate the process if memory for the selection
(aka clipboard) data can't be allocated. This should rarely
happen but if it does this is at least a "clean" exit and does
not overwrite arbitrary data waiting for later errors that are
hard to debug (as the old code would have done).
Todo: find a better solution because this can be caused by
another faulty process (the "selection owner"). It would be good
if we could ignore the transfer rather than killing the process.
- Continue processing the INCR protocol if another "unexpected" event
is received. Such events can definitely happen but the current code
can't deal with this because other events might cause recursions.
Hence such events are currently ignored.
Example: pressing and holding ctrl/v would trigger another clipboard
transfer while we're still processing one.
Todo: maybe process "other" events correctly while processing the INCR
protocol. The current processing is done inside a function and would
need to call fl_handle() with potential recursions, hence this would
likely need major refactoring.

- fix window size of GL windows as reported for test/glpuzzle.cxx
- fix window not resizing on ctrl/+/- (X11 only)
Unfortunately the previous commit "optimized" a necessary X11 message
away. This is now fixed.
Fixes #392.

For details see comment in src/Fl_x.cxx: this "Hack to speed up
bg box drawing" is now disabled for several reasons. The code
is still available if the macro ENABLE_BOXCHEAT is defined.

Windows platform: Remove comments about obsolete code and one
exported declaration of the variable 'fl_background_pixel' which
is used only on the X11 platform.
X11 platform: Remove comments.
Other platforms: not affected.

- Rename Fl_Screen_Driver::print_or_copy_window() to
fl_print_or_copy_window()
- Add header file src/print_button.h
- Update dependencies

These virtual members are moved from Fl_Screen_Driver to Fl_System_Driver

These virtual members are moved from Fl_System_Driver to Fl_Screen_Driver
- copy(const char *stuff, int len, int clipboard, const char *type)
- void paste(Fl_Widget &widget, int clipboard, const char *type)
- clipboard_contains(const char *type)

These members are moved from Fl_X11_Screen_Driver to Fl_X11_System_Driver
- poll_or_select_with_delay(double time_to_wait)
- poll_or_select()

src/print_button.cxx: "Print front window" implementation (new file)
This is compiled and activated if USE_PRINT_BUTTON is defined.
The feature can be fine controlled by environment variable
'FLTK_PRINT_BUTTON' (see docs in source file).

This undocumented macro is used on X11 and macOS platforms to
consolidate mouse move events, i.e. to collect some events and send
them later as one event. The old macro name CONSOLIDATE_MOTION has been
renamed to FLTK_CONSOLIDATE_MOTION since it is now a "global" symbol.
Users can define FLTK_CONSOLIDATE_MOTION in their build system, e.g.
on the compiler commandline, as 0 or 1 to disable or enable this
feature, respectively.
In FLTK 1.3 the default was 0 (OFF) on macOS and 1 (ON) on X11.
In FLTK 1.4 the default is always 0 (OFF).
|
|
Fix sending bogus events if CONSOLIDATE_MOTION is on.
|
|
Similarly move dlopen_or_dlsym().
This move is because GTK is not X11-specific.

Select the "best" target rather than a random one out of a list of
suitable targets. The old target selection algorithm would sometimes
select the wrong target and hence retrieve unexpected data.
This could happen in both copy-paste and drag-and-drop operations.
Note: backported to 1.3.6 (git current) as well
(commit 7ce6d2cf5dfc0488ec30d9f9f1709be73353479c).
Closes #182.

As discussed, only the window position becomes rounded to nearest integer value
when a fractional GUI scale factor is applied.

Use cairo-PostScript to output PostScript when pango is available.
This allows to draw in vectorial form any script.
Before, only the Latin script could be drawn to PostScript in vectorial form.

The intent is to gather in a single place of the X11 platform source code
all variable elements when using dlopen() and dlsym() system functions
(e.g., .so vs .dylib extension name, is RTLD_DEFAULT available, locations
to be sought).
Member function Fl_System_Driver::load() is created only to support
Fl_Plugin_Manager::load().

- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files
The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.

Note: there's more to do ...

Revert commit 958d912ffcdb using 'XSetLocaleModifiers("@im=");'
which was incorrect (STR 3192).
Apply fix for STR 3502, using 'XSetLocaleModifiers("");' which appears
to be the correct solution for using X Input Methods (XIM).
This has also been backported to FLTK 1.3.6 in branch-1.3, see
commit 219ae5e455e7943ffb35fdd5edbe13dcc6955423.

The X11 specific overloaded function fl_open_display(Display *)
has never been documented but exposed (and "exported" in the ABI)
in FL/platform.H which is not necessary. This internal function
is now static and no longer exposed in the ABI.
Don't confuse with fl_open_display() w/o arguments which is still
exported and declared in FL/platform.H.

Fix cut'n'paste error: needs #pragma pop instead of push.
|

... for GCC >= 4.6 and clang compilers.
This annoying warning exists on X11 (Linux/Unix/macOS) platforms
because we need to use XKeycodeToKeysym() although it is deprecated.
See STR 2913 for discussion and details.

X11 requires to process differently paste if both copy and paste are within the
same app or are in 2 separate apps. This was implemented for paste of text.
It's now also implemented for paste of image.

Under gnome, Tweaks -> Fonts ->Scaling factor allows to change
the size of all fonts handled by gnome.
With that change, FLTK apps obey to changes to Xft.dpi.

The procedure to set screen scaling factors becomes:
1) each screen scaling factor is set to 1
2) the OS is queried according to each platform to get screen scaling factor
values
3) The value of FLTK_SCALING_FACTOR, if present, is used to multiply
scaling factors

Fl_Window::is_shaped()
The new function allows to get the window's shaping image
and delete it after use, if appropriate.
