Many thanks to @wcout for providing this fix.
Xrender now draws images in the same way when tiling images
or not when FL_RGB_SCALING_BILINEAR is on.
This allows to remove static bool Fl_Tiled_Image::drawing_tiled_image()
which becomes unused.
The new method Fl::selection_to_clipboard(int) enables copying
selection data to the clipboard on X11 if it is set to 1.
This feature was requested by STR 3229 and the implementation was
inspired by an `xterm` feature named "Select to Clipboard" which can
be enabled by 'ctrl + middle mouse button + "Select to Clipboard"'
in an xterm window.
Add close buttons for Fl_Tabs
Introducing callback reasons
FLUID shows all FL_WHEN_... options
Adding Fl_Tabs overflow types
Improved test/tabs to show new features
This method can be used to draw small circles as part of the GUI.
It is independent of the current scheme.
Very small circles are approximated by drawing several rectangles.
This commit removes the unused variable as suggested in the discussion
of issue #445: "type issue in fluid/ExternalCodeEditor_WIN32.cxx"
... although the compiler would remove it anyway. ;-)
This commit has Fl_Cairo_Graphics_Driver compute string widths in 2 ways:
1) when the string contains several unicode characters, the width of the
whole string is computed, accounting for kerning when it occurs;
2) when the string contains a single unicode character, its width is
computed, memorised, and re-used next time it's necessary.
The effect of this approach is
- Fl_Text_Display is fast because it uses memorised single character widths repeatedly
- Fl_Input is drawn accurately because the cursor position is determined
by string widths, not by sums of character widths.
The "choice arrow" used two "down-arrows" which was different than
all the other schemes. Changed to up-arrow and down-arrow to make
this more consistent.
The exception is the default scheme (none or base) which uses only
one down-arrow.
FL_OVERRIDE is defined as `override` for C++11 and higher
FL_OVERRIDE is defined as `override` for VisualC 2015 and newer
Don't interfere with Fl_Widget::override()
- Add internal fl_contrast_cielab() as the new default.
- Keep old function as internal fl_contrast_legacy().
- Add fl_contrast_mode() to switch between fl_contrast() functions.
- Add fl_contrast_level() to fine tune fl_contrast() per mode.
- Add option to register and use a custom contrast function.
- Add test/contrast.cxx test program.
- Move all fl_contrast() related code to a new file src/fl_contrast.cxx.
- Add fl_lightness() convenience function for perceived lightness.
- Add fl_luminance() convenience function for physical luminance.
- replace enum value 'FRAMES' with 'const unsigned int frames'
- replace enum value 'DIM' with 'const unsigned int dim'
- remove commented statements that have never been used.
Note: this also changes uppercase enum values to lowercase constants.
