abaa550aea Simplify Fl_X11_Window_Driver::resize() when using cairo graphics. 2026-03-15 10:41:29 +01:00
ManoloFLTK
d8be762283 Fix use of the cairo graphics driver with Fl_Double_Window and the X11 platform (#1370). 
FLTK now handles Fl_Double_Window with the cairo graphics driver as with the X11 graphics driver:
- when drawing via the window's draw() method, FLTK draws to the offscreen cairo surface
and then copies the offscreen surface to the screen;
- when drawing outside the draw() method after a call to make_current(), FLTK draws to
a cairo surface associated to the mapped window.

e931c21e89 Correct draw translation by 0.5 pixels only 
Using 1.5 pixels causes text to be rendered one pixel offset to the top
left. This is visible when text is selected as the characters touch the
top left border.

The fl_text_extents is also updated to make sure the bounding box is
properly placed.

b9ff72c573 Revert "Prefix user-set window class name" (Windows only) 
... introduced in commit 81c965f8e2.

Note: we must not change the xclass (WNDCLASS) set by the user.

Setting another xclass() in FLTK demo programs where the name might
conflict with system WNDCLASS's is the better choice.

- minor comment and code formatting

This commit should not change the behavior.

3f56b8091d macOS: remove code present only to support macOS versions 10.6 and earlier. 
It's possible to build and run FLTK 1.5 with its use of C++11 for macOS 10.7 and SDK 10.7.
This commit makes 10.7 the required minimal version of macOS to build and run FLTK 1.5.

e9966b7e31 CMake: add try_compile() to figure out if Pen/Tablet is supported 
This test is specifically intended to disable Pen/Tablet support on
classic MinGW (32-bit) platforms that lack required symbol definitions
although Pen/Tablet support might be supported by the Windows system.

This test can be extended for other platforms, but for now it's
performed only on Windows.

bed38ba3f5 Emojis: add support of keycap emoji sequences. 
- It is expected that all emojis listed in the Wikipedia "emoji" article
as of early 2026 are recognized as single glyphs by FLTK text widgets.
- Document functions fl_utf8_{next|previous}_composed_char()
relatively to the notion of "emoji sequence".
- Remove signed/unsigned comparison compilation warnings.
