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

2016-01-271) Added a new way to detect whether the drawing operation is using the ↵Manolo Gouy
platform's native driver and whether we are printing: virtual int Fl_Graphics_Driver::has_feature(driver_feature feature) This is also because it is not convenient to derive a printer-specific driver with its own implementation of virtual functions when this implementation differs only in one line of code. 2) Solved the problem of inclusion of non public header by the public header FL/Fl_Device.H: bracket this with #if FL_LIBRARY / #endif so this non public header is included only when building FLTK itself. 3) Removed several (but not all) of the FLTK_ABI_VERSION guards that are no longer useful for code targeting FLTK 1.4. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11063 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2001-12-19Multiple bug fixes from Sebastien:Michael R Sweet
- Fl_GIF_Image and Fl_PNG_Image didn't close the file before calling Fl::error(). - Fl_Help_View didn't clear the line array in Fl_Help_Block, and Fl_Help_Block::font and ::size were not used. - Fl_Shared_Image::get() didn't return NULL if the image could not be loaded. - Switched to more efficient code for Fl_Tiled_Image::color_average() and ::desaturate(). - Don't delete children in Fl_Text_Display since the group will do it. - Fixes to filename_isdir(), filename_absolute(), and filename_relative(). - Was using numbers instead of define constants for some OpenGL stuff under WIN32. - Wasn't exporting threading functions under WIN32. - The Fl_Widget destructor now removes from the parent to avoid a Purify error since the old widget would be referenced by the parent when it was destroyed; this has no apparent performance impact since Fl_Group::clear() sets children_ to 0, making Fl_Group::remove() very fast... - WIN32 font enumeration datatype fixes... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@1878 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
