2017-05-17Introduce HiDPI + rescaling support for the X11 platform (+ partial support ↵Manolo Gouy
for WIN32) Corresponds to STR #3320 1) HiDPI support consists in detecting the adequate scaling factor for the screen on which FLTK maps a window, and scaling all FLTK units by this factor. FLTK tries to detect the correct value of this factor at startup (see more details below). Environment variable FLTK_SCALING_FACTOR can also be used to set this value. 2) Rescaling support consists in changing the scaling factor of all FLTK windows in reply to ctrl/+/-/0/ keystrokes. More details for the various platforms : - X11: Support is very advanced. Some details need still to be improved. Automatic detection of the correct starting value of the scaling factor works well with the gnome desktop. The present code contains no support for this on other desktops. FLTK_SCALING_FACTOR provides a workaround. -WIN32: Support is incomplete at this point, although many test applications have partial or complete HiDPI and scaling support. The current value of the system's scaling factor is correctly detected at application startup. Apps respond to changes of this value in real time. Support needs to define the FLTK_HIDPI_SUPPORT preprocessor variable at compile time. This way, standard builds produce a code with the default WIN32 HiDPI support, that is, where all graphics goes to an internal buffer that gets enlarged by the system and then mapped to the HiDPI display. To experiment with (or develop) the new HiDPI support requires a modified build procedure in which FLTK_HIDPI_SUPPORT is defined at compile time. When the support will be complete, the requirement for the definition of this preprocessor variable will be removed. The present commit contains support for a single scaling factor. Eventually, per-screen scaling factors should be implemented, as done for X11. - MacOS: this commit does not give new HiDPI for this platform. Eventually, window rescaling in reply to command/+/-/0/ is desirable. Per-screen scaling factor makes no sense on this platform because the OS itself takes care of the difference between the resolutions of traditional and retina displays. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12239 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2015-06-28Add documentation of Fl_Scroll::resize(...), fix some more Fl_Scroll docs.Albrecht Schlosser
As noticed in fltk.general, documentation of Fl_Scroll::resize() did not exist, hence the documentation shown was that of the parent class Fl_Group, which was definitely wrong. Some more minor documentation fixes have also been applied. No code changes. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10776 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2014-07-16* Modified the ScrollInfo structure for more modularity,Greg Ercolano

2000-06-05OK, now version 1.0.9Michael R Sweet
Updated email addresses to point to fltk.org domain... Updated README and CHANGES files accordingly.

2000-04-25Updated copyright notices for all of the 1.0.x files.Michael R Sweet
Updated the configure script for *BSD and GCC 2.95 (-fno-exceptions) Added install rule to documentation directory. Dumped old packages directory; added traditional RPM spec file and EPM list file (that replace all of the packages stuff) The FLUID man page is now "fluid.1" for the formatted page and "fluid.man" for the non-formatted page, since only IRIX uses pack'd formatted man pages. Whew! git-svn-id: file:///fltk/svn/fltk/branches/branch-1.0@1090 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2000-04-11I made FL_NORMAL_SIZE into a public int variable. You can now change itBill Spitzak
before any widgets are created, in order to change the default size of the fonts used. The most useful thing that can be done is to set it to 12 so that the default font size matches Win32. I also fixed the menubar drawing a bit so that a menubar with a FL_FLAT_BOX draws correctly. It should also be documented that "Fl::set_color(Fl_Color(15),0,0,128);" can be used to get Win32-style highlighting of menus and text items. This is not portable to fltk 2.0. With these changes it should be easier to get fltk to look just like Win32. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.0@1062 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
