2021-10-27Fix focus box drawing on X11 (partial fix for issue #156)Albrecht Schlosser
This fixes focus box drawing on X11 for some broken graphics drivers with line width zero as discussed on issue #156 titled "Incorrect rendering on Alpine Linux". This title is not entirely correct. The issue has been observed on other Linux distros as well if the "modesetting" driver is in effect. This does not fix rectangle drawing (missing pixels) in general which is obviously caused by a similar or the same driver issue.
2021-05-26X11: fix fl_clip_box() coordinates > 16-bit (STR 3134)Albrecht Schlosser
Pre-clip coordinates to 16-bit range before using X11 clipping functions because X11 supports only 16-bit int's.
2021-03-11Unification of scaled coordinate calculations in class ↵ManoloFLTK
Fl_Scalable_Graphics_Driver Most coordinate calculations are done with the new inline function int Fl_Scalable_Graphics_Driver::floor(int coord) that is used by both the Windows and X11 platforms.

2020-07-06Remove $Id$ tags, update URL's, and moreAlbrecht Schlosser
- remove obsolete svn '$Id$' tags from all source files - update .fl files and generated files accordingly - replace 'http://www.fltk.org' URL's with 'https://...' - replace bug report URL 'str.php' with 'bugs.php' - remove trailing whitespace - fix other whitespace errors flagged by Git - add and/or fix missing or wrong standard headers - convert tabs to spaces in all source files The only relevant code changes are in the fluid/ folder where some .fl files and other source files were used to generate the '$Id' headers and footers.

2018-03-13Improve and simplify X line and rect 16-bit clipping.Albrecht Schlosser
Back to 16-bit coordinate limit clipping (actually +/- (2**15 - 8). The clipping range is now constant, symmetrical, and stored in the driver object. Also fixed a bug in Liang-Barsky line clipping algorithm. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12744 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2018-03-09Improve X11 (16-bit) clipping of lines and rectangles.Albrecht Schlosser
In FLTK 1.3.x only horizontal and vertical long lines with endpoints outside the 16-bit coordinate space could be drawn with proper X11 coordinate clipping. Now arbitrary lines are clipped so they can be drawn with X11 functions. All rectangles are clipped as well (as in 1.3). Todo: The code needs better documentation and clipping of polygons, circles, curves etc. is still missing. The next step should be the clipping of polygons... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12725 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
