2018-02-09Replace "WIN32" with "_WIN32" or "Windows".Albrecht Schlosser
Replace compiler/preprocessor/platform macro "WIN32" with "_WIN32". Replace "WIN32" in text and documentation with "Windows". Replace "MSWindows" with "Windows". To do: README.Windows.txt (and maybe other documentation as well) needs updates. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12655 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

2009-08-28Applied patch from STR#2115.Greg Ercolano
This fix to fl_height(int,int) solves the "digital drit" problem in Fl_Text_Editor, where doing insert/delete operations was leaving a trail of dead pixels. Also fixes problem with font display problem in fluid's code editor. See the STR for screenshots of the problem. NOTE: THIS IS A WORKAROUND FOR A DEEPER PROBLEM. Somewhere during the port of UTF8, the actual pixel size of the displayed font is a little off, causing FLTK to miscalculate line height, causing 'digital drit'. It used to be that when you specified a font size, the font's actual displayed pixel size matched the font size value. This fix makes the fl_height(int,int) function more robust, actually inquiring the font system for its font size, instead of assuming the font size is the same as the 'size' argument. Since Fl_Text_Editor makes use of this function, it helps that widget calculate font sizes correctly. The real fix will be restoring FLTK's old behavior where the font size specified is the actual pixel size of the displayed font. Then this function can be reverted to just returning the 'size' argument. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6845 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
