- May need a better method name.
- This makes the gap between the image in a label and
the label text user settable.
- Can be tested using test/label app
This commit consists of two parts:
1. CMake/resources.cmake: remove the old variable OPENGL_GLU_INCLUDE_DIR
from the CMake cache if possible, otherwise enforce a clean build.
2. src/CMakeLists.txt, CMake/options.cmake: use the new variable name
FLTK_OPENGL_GLU_INCLUDE_DIR.
For details please see GitHub Issue #1001.
Pressing Home would go to hard newline character, even in
line wrap mode. It now stops at the soft newline, as expected.
Same for End which now findes the wrapped line break
instaead of the next '\n' character.
- append underscores to private varaibles per CMP
- add public Fl_Help_View::copy() and Fl_Help_View::text_selected()
- add public Fl_Help_View::copy_menu_text
- fixes some of the focus handling
- add pulldown menu to copy selected text
Language wrappers can have major issues with FLTK auto deleting
all children of a group if a group is deleted. This event gives individual
widget the opportunity to override auto delete.
This fix solves these warnings:

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.
- Restrict FL_BUTTONS mask to only three valic mouse buttons.
Pseudo mouse buttons 4-7 are used for FL_MOUSEWHEEL events and
are no longer reflected in Fl::event_buttons().
- Return only state of mouse buttons 1-3 in Fl::event_buttons().
Buttons 4-7 are not "sticky" (used for FL_MOUSEWHEEL).
- Keep undefined keyboard related bits in Fl::event_state() for
backwards compatibility and transparency. These bits may be masked
out in a later release.
- Document Fl::event_state() bits for X11 in src/Fl_x.cxx.
Note: this is a bug fix for X11 only, Wayland and other platforms are
not affected.
