(1) convert tabs to spaces
(2) remove trailing whitespace

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().

The code falls back to the ad-hoc method if uuid_generate() isn't available.

A lot of code touched because low level functions needed to pass up
error messages reliably, and this had to propagate up the entire
driver hierarchy.
Tested OK *in English* on:
> Linux
> OSX 10.10.x
> Windows VS2017
> Windows mingw64
I have no way to test on Android, but it might work.
TODO: Needs testing in other languages to verify proper UTF8 error messages,
esp. with Windows VS, due to complexities with FormatMessage() -- see get_ms_errmsg()

- 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.

Fix for issue #90: Setting an svg image as a window icon causes a segfault.

There are now 2 kinds of GTK libraries (V2 and V3) and two dialogs
the file chooser and the printer chooser.
|
|
The main fixes are only to avoid static code analyzer warnings reported
in issue #5, but there are also minor bug fixes included. These bug
fixes are more of theoretical concerns though.
Close #6.

Added Fl_Preferences::file_access() and various flags that make it possible to limit or completely deny file access to the preferences system, either for the core library or for the application or both.

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.

A recent commit changed the library name, supposedly unintended.
While testing I found that the debug statements generated confusing
output (both "selected GTK-3" and "selected GTK-2") when GTK-3 was
available.

run-time
The code to determine whether the GTK library is available is now in Fl_X11_System_Driver::probe_for_GTK()
called both by Fl_Printer::begin_job() and Fl_Native_File_Chooser.
New Fl::option OPTION_PRINTER_USES_GTK allows to deactivate use of
the Gnome print dialog.
Minor change in Fl_Native_File_Chooser: GTK version 3 is searched before version 2,
whereas the search order was the opposite before.

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).
|
|
The new argument gives the window to be captured, or NULL to indicate capture
from the current offscreen.
Calling this function becomes easier because less dependent on global variables.
