2022-12-09Suppress (GitHub CI/wayland) compiler warningAlbrecht Schlosser
[ 15%] Building CXX object src/CMakeFiles/fltk.dir/Fl_Text_Display.cxx.o .../fltk/src/Fl_Text_Display.cxx: In constructor ‘Fl_Text_Display::Fl_Text_Display(int, int, int, int, const char*)’: .../fltk/src/Fl_Text_Display.cxx:122:57: warning: ‘void* __builtin_memset(void*, int, long unsigned int)’ writing between 4 and 8589934584 bytes into a region of size 0 overflows the destination [-Wstringop-overflow=] 122 | for (int i=1; i<mNVisibleLines; i++) mLineStarts[i] = -1; | ~~~~~~~~~~~~~~~^~~~ .../fltk/src/Fl_Text_Display.cxx:120:39: note: at offset 4 into destination object of size 4 allocated by ‘operator new []’ 120 | mLineStarts = new int[mNVisibleLines]; | ^ This warning is IMHO obsolete because the code in question should not be executed at all (mNVisibleLines == 1). However, the compiler seems to substitute this with '__builtin_memset(...)' and analyzes "correctly" that memory at offset 4 would be overwritten but not that the written size would be 0. The "fix" uses a compiler macro and #if to clarify that this code must not be executed and should not be compiled (see comment why this code exists).

2022-12-09Fix Fl_Text_Display drawing of line numbers (#578)wcout
The formerly undrawn rectangle beneath (or above) the line numbers is now filled with FL_BACKGROUND_COLOR. Additionally the small rectangle between the scrollbars is now filled with FL_BACKGROUND_COLOR instead of FL_GRAY for consistency.

2022-11-29Fix for issue [Cairo]: Arrows have a "gap" (#561)ManoloFLTK
The problem to fix is that the arrow drawn by draw_arrow1() in src/fl_symbols.cxx displays a faint clear line between the stem and head of the arrow with the Cairo graphics driver. This occurs because draw_arrow1() draws the arrow in 2 steps (a rectangle + a triangle) and the Cairo driver is configured to use antialiasing when filling polygons. The antialiasing produces the faint line between stem and head. Why does draw_arrow1() draw a rectangle + a triangle rather than a 7-vertex polygon? That's because the X11 graphics driver fails with its polygon- drawing function when the polygon is also rotated: the polygon is drawn empty. We want to keep using antialiasing under Cairo for polygons because the result is better with non horizontal/vertical polygon edges. This implementation changes function draw_arrow1() which draws the arrow as a 7-vertex filled polygon except when the graphics driver returns false for its virtual member function can_fill_non_convex_polygon(). In that situation, draw_arrow1() draws, as before, a rectangle + a triangle. The new, virtual member function can_fill_non_convex_polygon() returns true except for the X11 graphics driver. Therefore, draw_arrow1() is effectively unchanged under the X11 driver.

2022-11-26Make the value box size of Fl_Value_Slider user settable (STR 3222)Albrecht Schlosser
For a very simple test program see STR 3222, File 2: https://www.fltk.org/strfiles/3222/value_slider.cxx Known issues: - range checking of the value box size is very limited - resizing the widget does not change the value box size - drawing issues are possible if the value box size and the widget size are not compatible (e.g. value box too large)
