2026-01-08Add CMake option FLTK_OPTION_PEN_SUPPORT (default: ON)Albrecht Schlosser
This option can be used to disable pen/tablet support if there are build problems on a particular platform or build system (e.g. MinGW) so users can continue to build FLTK 1.5. Users can also choose to disable pen support if they don't need it.

and declare it in non-public header src/Fl_Scalable_Graphics_Driver.H which also declares classes Fl_Font_Descriptor and Fl_Fontdesc.
2025-04-18Fix "heap-use-after-free" in resize_after_screen_change() (#1248)Timothy Lee
When a native window is destroyed, make sure the callback to Fl_WinAPI_Window_Driver::resize_after_screen_change() is removed. Added by Albrecht-S: Thanks for the original fix to Timothy Lee (@timothytylee). src/drivers/X11/Fl_X11_Window_Driver.cxx: equivalent fix for X11 as discussed on GitHub PR #1248
2025-03-07Fix "fltk autotools build does not link against libXft" (#1202)ManoloFLTK
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".
2025-02-24Remove deprecated, commented-out code.ManoloFLTK
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.

2024-07-17Simplify creation of OpenGL contexts under X11 platform (#1005)ManoloFLTK
The previous approach FLTK used to create OpenGL contexts under the X11 platform followed a different code path to create contexts for OpenGL version 3 and above than to create contexts for OpenGL versions 1 or 2. The FLTK code followed exactly "Tutorial: OpenGL 3.0 Context Creation (GLX)" of the official OpenGL wiki, see: https://www.khronos.org/opengl/wiki/Tutorial:_OpenGL_3.0_Context_Creation_(GLX) That code worked OK with Debian 11 and with any tested Linux configurations in a VM running on Apple hardware. However, it failed with Debian 12 and later on native Linux boxes to create GL3 contexts with the FL_DOUBLE flag. That's what issue #1005 reports. A first attempt to fix #1005 followed instructions given at: https://registry.khronos.org/OpenGL-Refpages/gl2.1/xhtml/glXIntro.xml which supposedly describe how to create OpenGL contexts with GLX. That had no effect on issue #1005. This commit erases all attempts to use OpenGL3-specific calls or even the more modern glXCreateNewContext() function that appears with GLX version 1.3. The committed code uses only OpenGL 1-age functions to create OpenGL contexts for X11 windows. Created contexts follow the "Compatibility Profile" which means they are compatible with both modern OpenGL3-style and legacy OpenGL1/2-style. This appears to fix issue #1005.

2024-03-16Fix memory leak in Fl_X11_Screen_Driver.cxx (#934)Albrecht Schlosser
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.

2023-10-07Fix STR 3458: "GLUT compatibility mode segfaults"Albrecht Schlosser
... "when there's no current window". Silently ignore GLUT function calls that need a current window if the current window is NULL, return 0 from functions that return an 'int'. Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers(). This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise. Note: the chosen implementation to ignore GLUT calls silently appears to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error messages and exit. The latter could be implemented as well but would be much more work.
