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

2017-05-17Introduce 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

the same as the check which is subsequently used before calling dlsym() and dlopen().

2015-12-02Mac OS: support for high resolution OpenGL windows.Manolo Gouy
Methods Fl::event_x_pixel() and Fl::event_y_pixel() committed at r.10941 are removed. Instead method Fl_Gl_Window::pixels_per_unit() is added. The documentation explains in more detail how to write cross-platform FLTK code supporting high resolution OpenGL windows on retina displays. The examples/OpenGL3test.cxx app exercises Fl_Gl_Window::pixels_per_unit(). git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10945 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2015-09-08The Fl_Gl_Window public API offers 2 ways to control the OpenGL capabilities ↵Manolo Gouy
of a window: 1) Fl_Gl_Window::mode(int m) is platform-independent and uses an argument containing bit flags (e.g., FL_DOUBLE, FL_RGB8) to express desired capabilities. The m argument is assigned to the mode_ private member variable of the Fl_Gl_Window object. 2) Fl_Gl_Window::mode(const int *a) is highly platform-dependent. It uses a zero-ending array of attributes or attribute-value pairs to express capabilities. This member function can be used on the X11 and the Mac OS platforms, but not with MSWindows. Before this patch, the mode_ private member variable of the Fl_Gl_Window object is assigned 0 by this member function. The Fl_Gl_Window::flush() member function tests whether the FL_DOUBLE flag is ON in the mode_ variable, and changes code path accordingly. Therefore, the second API to control OpenGL capabilities fails when a double-buffered GL context is required, because the code path followed by Fl_Gl_Window::flush() does not match the GL context requirements. With this patch, Fl_Gl_Window::mode(const int *a) scans the content of its array argument, and sets the FL_DOUBLE bit of the mode_ member variable if the array requires a double-buffered GL context. This patch does that for the X11 platform. The same was introduced for the Mac OS platform at r. 10854. The MSWindows platform does not use the Fl_Gl_Window::mode(const int *a) API. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10859 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2014-12-20Changed OpenGL support for the Mac OS X platform: use cocoa instead of ↵Manolo Gouy
deprecated AGL. All changes are mac-specific, except a very minor change in file src/gl_draw.cxx where string drawing wrongly claimed to support @symbol, not possible because symbols are drawn using non-GL primitives. Unchanged application code can use the new FLTK code. In addition, the new code allows mac applications to draw OpenGL scenes at high resolution on so-called 'retina' displays, but this requires some support from app code. They must call, before opening GL windows, Fl::use_high_resolution(1); and change their glViewport() calls as follows glViewport(0, 0, pxel_w(), pixel_h()); This uses 2 new member functions of the Fl_Gl_Window class, pixel_w() and pixel_h() returning the window dimensions in pixel units, that is, twice the w() and h() when the window is mapped on a retina display. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10498 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
