2017-08-18Avoid #include's of unrelated system headers in Fl_Table*.H.Albrecht Schlosser
Possible side effect: programs that relied upon inclusion of unrelated system headers by FL/Fl_Table.H or FL/Fl_Table_Row.H may fail to compile. Removed include files (some only on certain platforms, list may be incomplete): #include <FL/Fl.H> // moved to implementation (.cxx) #include <FL/Fl_Box.H> // moved to implementation (.cxx) #include <FL/Fl_Scrollbar.H> // moved to implementation (.cxx) #include <sys/types.h> #include <string.h> // memcpy #include <malloc.h> // WINDOWS only: malloc/realloc #include <stdlib.h> // UNIX: malloc/realloc git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12390 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

Fl_Text_Selection got a new method length() and returns 0 in length() and in all offsets (start(), end(), position()) if no text is selected (selected() == false). The behavior in FLTK 1.3 and earlier versions (returning undefined values if !selected()) was confusing. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12356 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2017-07-25Rewrite Fl_Window_Driver::resize_after_scale_change() removing calls to ↵Manolo Gouy
Fl_Window::hide() and Fl_Window::show(). Windows are now rescaled with a call to Fl_Window::resize() which has been slightly modified. Static member variable bool Fl_Window_Driver::in_resize_after_scale_change is created, and is true if and only if Fl_Window::resize() is called by Fl_Window_Driver::resize_after_scale_change(). This new flag allows Fl_Window::resize() to perform correctly the rescaling of the window. Fl_Gl_Window::resize() and Fl_Double_Window::resize() also consult the value of the Fl_Window_Driver::in_resize_after_scale_change flag. The platform-specific Fl_WinAPI_Window_Driver::resize() and Fl_X11_Window_Driver::resize() also use the Fl_Window_Driver::in_resize_after_scale_change flag. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12349 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2017-07-20Improve docs of Fl_Widget::callback() and do_callback().Albrecht Schlosser
Clarify that all variants of do_callback() call clear_changed() after the callback and that 'long Fl_Widget::argument()' may truncate the user_data value on some (particularly Windows 64-bit) platforms. Some code has been reformatted and refactored with better variable names, but there are no effective code changes.

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

New method Fl_Tabs::tab_align() supports icons in tabs (STR #3076). This commit also enables drawing labels of Fl_Window children (STR #3075). Setting tab_align(FL_IMAGE_NEXT_TO_TEXT) draws images (icons) in the tab labels if the child has an image(). Currently this draws the image() even if the child is deactived (so it should presumably draw the deimage()).
