2017-08-14Remove unnecessary #include statements and compilation guards.Albrecht Schlosser
Currently src/drivers/OpenGL/Fl_OpenGL_Graphics_Driver.cxx wouldn't contribute any code to the lib, but it is kept for future extensions. This file is no longer compiled (see src/CMakeLists.txt and src/Makefile). Tested (only) under Windows and Linux. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12381 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

2016-11-28X11 platform: fix STR#3353 and correct drawing of depth-2 RGB images when ↵Manolo Gouy
XRender extension is present. Fl_RGB_Image's of depth-2, that is, monocolor and transparent, were not drawn using the XRender extension, when present, as are depth-4 images. With this change they are. A by-product of this change is that it fixes an erroneous drawing (STR#3353) that occurred when the image expands outside the window. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12124 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2016-11-18Fix for STR#3353: bad depth-2 image drawing when the window is resized ↵Manolo Gouy
smaller than the image. The problem is specific to the X11 platform. The cause is that depth-2 images were not considered in a previous change (r.10628) that introduced transparent image drawing with alpha blending. Depth-2 images can be processed just as depth-4 images with alpha-blending. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12120 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
