2021-08-27Remove compiler warnings '-Wextra-semi' (see also PR #266)Albrecht Schlosser
I compiled with `-Wextra-semi -Werror=extra-semi` on Linux and Windows (cross-compiled on Linux) and removed all "extra semicolon" warnings I could find. I didn't check on macOS (yet). Note: Linux configured with and w/o Pango but not w/o Xft. Compilation with other options (e.g. Cairo) might still emit such warnings.

2021-04-27Slightly simplify gl_texture_fifo::compute_texture()ManoloFLTK
The font size is set to the value necessary for the GL scene before computing the string width. Virtual Fl_Gl_Window_Driver::effective_size() becomes unnecessary.

2020-07-06Remove $Id$ tags, update URL's, and moreAlbrecht Schlosser
- 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.

2019-06-18Avoid "uninitialized memory" error in gl_drawAlbrecht Schlosser
As discussed in fltk.general, valgrind reported errors when gl_draw() is called and the text is converted to a texture (i.e. when testing whether the texture already exists). We need a length check to make sure we don't overrun text buffers. See threads "gl_draw" and "gl_draw - [General Use]", respectively, started on Jun 19, 2019.
2019-04-10Save and restore GL parameters as appropriateAlbrecht Schlosser
According to the docs "glPixelStorei sets pixel storage modes that affect the operation of subsequent glReadPixels as well as the unpacking of texture patterns (see glTexImage2D and glTexSubImage2D)." Hence we (a) must be aware that current values of these modes can be anything set by user or FLTK code before (b) should be polite and restore these modes to previous values See discussion in fltk.coredev, thread "gl_draw problem" started on Apr 05, 2019.

2018-06-23Removed macro FL_PORTING, as it has been more confusing than helpful.Matthias Melcher
The original intention of FL_PORTING was to mark all places in the source code where changes are required to port FLTK to a new platform. Thanks to the driver system, this approach has become somewhat misleading, so I removed all references. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12969 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2016-03-29Remove the platform-dependent type xcharManolo Gouy
File fl_utf8.h defines the xchar type with a platform-dependent value (wchar_t or unsigned short). But it is used exclusively by WIN32 code (0 use in cross-platform code, 0 use in APPLE or in USE_X11 code). Thus, we can just get rid of this type and replace it by wchar_t where it is used. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11459 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
