2022-09-27Simpler code to support FLTK widgets in macOS OpenGL 3 windows.ManoloFLTK
Also, the application-level code to add widgets to a GL3 window becomes platform-independent.
2022-09-26Replace all calls to sprintf() by calls to snprintf().ManoloFLTK
2022-09-25Add cross-platform support for adding widgets to an OpenGL3-based Fl_Gl_Window.ManoloFLTK
Under non-macOS platforms, the key is to call glUseProgram(0); after having used OpenGL 3 which allows to then use OpenGL 1 and draw FLTK widgets over the OpenGL3 scene. Under macOS, this is impossible because macOS GL3 contexts are not compatible with GL1. The solution implemented here is to create an additional Fl_Gl_Window placed above and sized as the GL3-based window, to give it a non opaque, GL1-based context, and to put the FLTK widgets in that additional window.
2022-09-23Use adequate #include for fl_wl_display().ManoloFLTK
2022-09-22Wayland: fix error detection during call to glewInit().ManoloFLTK
2022-08-08Add option to test Fl_Flex in test/pack.cxxAlbrecht Schlosser
This new feature demonstrates that Fl_Flex can be used (almost) as a drop-in replacement of Fl_Pack. Add missing file to examples/.gitignore.
2022-08-07Add Fl_Flex demo "howto-flex-simple" to examplesAlbrecht Schlosser
This demo program uses an Fl_Flex widget with one row of buttons.

2022-01-17Remove unnecessary CMake test statement (#358)Albrecht Schlosser
Sorry for the noise, this statement was included in my proposed patch.
2022-01-16Issue #358 cont'd: Fl_Cairo_Window coord system docsGreg Ercolano
Elaborated on Fl_Cairo_Window's use of FLTK style coordinates, and how this differs from cairo's default native normalized coordinate system, and shows how to switch from one to the other. Also, small comment fix to the cairo example regarding the "X" color.
2022-01-16Adding Albrecht's CMakeLists.txt patchGreg Ercolano
Albrecht submitted this in issue 358. Tested the variations: cmake .. -- examples and cairo off cmake -D FLTK_BUILD_EXAMPLES=on -- examples on, cairo off cmake -D FLTK_BUILD_EXAMPLES=on -D OPTION_CAIRO=on .. -- examples on, cairo on When examples are 'on', they build into the bin/examples directory.
2022-01-16For issue #358 - adds examples/cairo-draw-x.cxxGreg Ercolano
Since this is the first cairo example in the examples directory, it necessarily involved changes to the Makefile and to fltk-config to properly handle the absence/existance of the cairo libs. TBD: Add docs to the cario widget describing coordinate system and how it differs from the default cairo normalized coordinate system.
2021-11-18Reformat and move clipboard demo from examples to test folderAlbrecht Schlosser
The clipboard demo is more a test program than an example and very useful even if the examples are not built. Also update dependencies.

2021-08-30Fix two compiler warnings [-Wunused-variable]Albrecht Schlosser
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.

Add includes of system headers in the implementation files where necessary.
2021-03-19Add fluid callback demo program to examples folderAlbrecht Schlosser
This example demonstrates how to build an entire program using fluid and how to add static and virtual class methods as callbacks.

2021-02-15Update CMake and make files, minor edits onlyAlbrecht Schlosser
There are no functional changes to be expected, mostly formatting and comments.
2020-08-21Fix examples build (configure/make)Albrecht Schlosser
Fix more issues caused by moving fltk-versions from examples to test and adding examples to the CMake build process (gitlab-ci)
2020-08-21CMake: add examples folder to build (optional)Albrecht Schlosser
- replace misnamed option 'OPTION_BUILD_EXAMPLES' with 'FLTK_BUILD_TEST' - add option 'FLTK_BUILD_EXAMPLES' to build apps in examples folder - move examples/fltk-versions.cxx to test/fltk-versions.cxx - [Travis-CI] enable option 'FLTK_BUILD_EXAMPLES' for automatic builds
2020-08-20Fix link and comments in example programAlbrecht Schlosser
The mentioned link to fltk.general was incorrect; fixed and added thread title for further reference. Fixed typo and adjusted comments.

2020-08-01Implement + deploy fl_strdup()Greg Ercolano
2020-07-13A few extra comments for table-spreadsheet.Greg Ercolano
Also small but unnecessary code change to reset row_edit/col to zero after editing for example clarity. Unnecessary b/c those vars are ignored anyway when input visibility turned off, so change is more cosmetic codewise.
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.
2020-06-29Move class Fl_SVG_File_Surface from libfltk to libfltk_images.ManoloFLTK
File examples/SVG_File_Surface.cxx is no longer useful because it was a very partial implementation of what is now class Fl_SVG_File_Surface.
2020-04-20Reorganize .gitignore file(s)Albrecht Schlosser
Move ignored files in /examples/ and /test/ to their own folders, i.e. to examples/.gitignore and test/.gitignore, resp.
