and declare it in non-public header src/Fl_Scalable_Graphics_Driver.H which also
declares classes Fl_Font_Descriptor and Fl_Fontdesc.

libXft was erroneously present in the link command when using Pango and Cairo.
This is fixed by disconnecting the GUI scaling code from use of Xft.
This commit also makes sure that when Wayland is used, pkg-config is available
on the build machine. This allows to remove from file CMake/options.cmake
code that was labelled with "FIXME".
|
|
This code was used in the past to support a deprecated way to obtain the initial
value of the GUI scaling factor for the X11 platform.

Add system check for setenv() function in configure and CMake.

Fl_X11_Screen_Driver::set_spot() did not free the list of missing
fonts returned by XCreateFontSet().
This commit also initializes some variables and reformats code, but
the only notable change is to call XFreeStringList(missing_list) if
missing_list is not NULL.

Please note that the parameter 'percent' of XBell(3).
Given the value of 100, the system defined setting
(normally specified via xset) is ignored and the
percent of 100 is used instead. When calling the
bell from fltk with FL_BEEP_DEFAULT I would expect
to get the default (system specified) percent setting.

This is only one part of issue 461 which describes two build errors
on "Raspberry Pi4 bullseye". It turned out that the build didn't
find Xft.

These virtual members are moved from Fl_Screen_Driver to Fl_System_Driver
- wait(double)
- ready()
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)
- clipboard_notify_change()
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()
and are made virtual in preparation for the introduction of class
Fl_Unix_System_Driver.

Add Fl_Timeout class
Move platform independent code of Fl::wait() to main part
- basic timeout handling
- Fl::run_checks()
- Fl::run_idle()
- Fl::idle()
- waiting time calculation (next timeout)
- remove platform dependent "screen driver" stuff

Implement a new way to make the GTK file-chooser window modal-like
by preventing any event processing by other FLTK windows.
The new way is also no longer X11-specific.

RGB images are now drawn to a size that exactly fit discretised rectangles when non
integral GUI scaling values are used.
|
|
Some of the previous constness changes turned out to be incomplete,
others had to be reverted because some other driver methods could
not be made 'const' - particularly those calling open_display() to
get the requested information.
|
|
Similarly move dlopen_or_dlsym().
This move is because GTK is not X11-specific.

Fl_Scalable_Graphics_Driver
Most coordinate calculations are done with the new inline function
int Fl_Scalable_Graphics_Driver::floor(int coord)
that is used by both the Windows and X11 platforms.
|
|
|
|
The change lets this function enlarge the size only when strictly necessary
for image tiling.
|
|
|
|
As discussed, only the window position becomes rounded to nearest integer value
when a fractional GUI scale factor is applied.
|
|
Changes here concentrate the fix within static function alpha_blend() and thus
are visible only when drawing transparent images under X11 platform
without Xrender.

Fl_WinAPI_Screen_Driver::read_win_rectangle_unscaled()
Thanks to "fire-eggs" for spotting it.
Also minor optimisations in Fl_X11_Screen_Driver::read_win_rectangle_unscaled() and
Fl_Cocoa_Screen_Driver::read_win_rectangle_unscaled().
This closes PR #151.
|
|
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.

See comment 14 (excerpt):
"The current implementation basically handles add_timeout() the same
way as repeat_timeout(), i.e. add_timeout() *calls* repeat_timeout().
However, repeat_timeout() intentionally *corrects* the timeout value
by the value found in the global variable 'missed_timeout_by' which
is set when the timer expires, directly before the timer callback
is called. This variable is never reset."
This commit resets the variable as necessary in Fl::add_timeout().

Timeouts queued during Fl_Widget::draw() - called by Fl::flush() -
would not be serviced unless other events were processed. For
Details see STR 3188.

The case was under macOS with a non-GL parent window mapped to a retina display
containing a GL subwindow and if the app did not call Fl::use_high_res_GL(1).
