2024-12-04Improve timer statistics in test/cube demoAlbrecht Schlosser
These timer statistics are useful to see the interaction of OpenGL drawing and FLTK timers (Fl::add_timer + Fl::repeat_timer).

2024-12-01Use a constant frame rate (25 fps) in test/cube demoAlbrecht Schlosser
The old version was "synchronized" by calling Fl::check() in a loop which resulted in the highest speed possible on any platform. It turned out that this was way too fast on the Wayland platform as `valerius` posted on IRC/Matrix on Nov 30, 2024. Citation: "anyone else notice the cube demo on Wayland is mega ultra hyper speed?". I took the opportunity to change the demo to use a timer with a given frame rate (see constant 'FPS') to synchronize drawing. Note: the 'speed' slider is independent of the drawing frequency. Finally this commit adds statistics output when the 'Stats / Exit' button is pressed like Iterations = 304, runtime = 12.167 sec, fps = 24.99, requested: 25 with the requested frame rate (default = 25) and allows the user to continue to see more statistics. To do (very likely not in 1.4.x): 1. integrate running statistics in the display 2. make the desired frame rate variable at runtime (new slider)

2023-10-20Fix ctrl/+/- in cube demoAlbrecht Schlosser
- Fl_Grid: force layout() on resize() - needed for GL subwindows - test/cube.cxx: - use end() in constructor of class cube_box - ensure not to change the current group when adding a button

- FL/Fl_Grid.H: header file - src/Fl_Grid.cxx: implementation - examples/grid-simple.cxx: simple example program - test/cube.cxx: use Fl_Grid for layout - test/grid_alignment.cxx: test cell alignment and other functions - test/grid_buttons.cxx: demo program as discussed in fltk.general - test/grid_login.cxx: like test/flex_login.cxx but with Fl_Grid - test/flex_login.cxx: modified to match test/grid_login.cxx

2022-02-06OpenGL implementation of all `fl_` "Drawing Fast Shapes" graphics calls (#385)Matthias Melcher
* Fix build system for unites, * Updated unittest to check OpenGL drawing. Making sure that OpenGL drawing is exactly the same as native drawing to make FLTK widget rendering look the same in GL windows. * Make OpenGL optional. * Implemented clipping in OpenGL * unites drawing fast shapes * Fixed CMake * Updating unittest.

2020-11-24Improve resizing of test/cube demo (#157, #166)Albrecht Schlosser
Based on Greg's mods in 'cube-v5a-patch.txt' in this issue #157 comment: https://github.com/fltk/fltk/issues/157#issuecomment-732496554 Simplify the layout and keep border widths constant: - combine left GL window + buttons (ct_group) in left group (lt_grp) - make the cube Fl_Gl_Windows the resizable()s of their respective groups. The latter keeps the margin widths constant.
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.
2019-11-08Don't use Fl::readqueue() in cube demoAlbrecht Schlosser
Usage of Fl::readqueue() is not recommended (should be deprecated?), hence we shouldn't use it in our demo program(s). To do: remove Fl::readqueue() usage from fluid.

2014-12-20Changed OpenGL support for the Mac OS X platform: use cocoa instead of ↵Manolo Gouy
deprecated AGL. All changes are mac-specific, except a very minor change in file src/gl_draw.cxx where string drawing wrongly claimed to support @symbol, not possible because symbols are drawn using non-GL primitives. Unchanged application code can use the new FLTK code. In addition, the new code allows mac applications to draw OpenGL scenes at high resolution on so-called 'retina' displays, but this requires some support from app code. They must call, before opening GL windows, Fl::use_high_resolution(1); and change their glViewport() calls as follows glViewport(0, 0, pxel_w(), pixel_h()); This uses 2 new member functions of the Fl_Gl_Window class, pixel_w() and pixel_h() returning the window dimensions in pixel units, that is, twice the w() and h() when the window is mapped on a retina display. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10498 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2001-03-14Replaced remaining _WIN32 symbols with WIN32Bill Spitzak
Stuff from work: Removed reference to unused GL/glu.h header file, which is missing on some Linux systems. Fl_Gl_Window has a new method to allow you to get and set the context: void Fl_Gl_Window::context(void*, int destroy = 0) void* Fl_Gl_Window::context() const; Return or set a pointer to the GLContext that this window is using. This is a system-dependent structure, but it is portable to copy the context from one window to another. You can also set it to NULL, which will force FLTK to recreate the context the next time make_current() is called, this is useful for getting around bugs in OpenGL implementations. If destroy_flag is true the context will be destroyed by fltk when the window is destroyed, or when the mode() is changed, or the next time context(x) is called. Some cleanup of Fl_Gl_Choice to move most of the system dependent #ifdefs into Fl_Gl_Choice.cxx. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.0@1413 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
