2017-06-01Divide virtual Fl_Screen_Driver::open_display() in a platform-specific part ↵Manolo Gouy
followed by a platform-independent part. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12245 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
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

2016-02-17Fix compilation under Linux - compiles, but doesn't work :-(Albrecht Schlosser
I moved all timer related (X11) stuff from src/Fl.cxx to src/drivers/X11/Fl_X11_Screen_Driver.cxx and added externals as done by Ian in a previous commit for the WinAPI screen driver. I did not (yet) remove the code from Fl_x.cxx though, but disabled it. See: #if (0) // *FIXME* moved to src/drivers/X11/Fl_X11_Screen_Driver.cxx Current state is that FLTK can be compiled and linked again (under Linux) but doesn't work (shows empty windows only). I thought it was worth to commit my work, but can't check what's going on right now - other devs should feel free to continue this. PS: the new code in src/drivers/X11/Fl_X11_Screen_Driver.cxx was just dropped in, keeping the right order for usage of static helper functions, but should be fixed in all regards (order, logic, ...). git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11185 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
