The problem is that the app sometimes stops after closing a file dialog window.
It results in fact from a bug in function draw_title_bar of libdecor-gtk.c that erroneously
calls libdecor_frame_set_max_content_size(). This bug is being proposed to be fixed
by a MR to libdecor.
But moving the libdecor_frame_set_min/max_content_size() calls after the capability changes
hides the bug, and the problem with file dialog doesn't show.
This removes the need to edit the copyright year before generating
the documentation (every year, in several files) and adds some
technical information (doxygen generation date, doxygen version,
and FLTK Git revision) in both HTML and PDF docs.
- auto-generate copyright year (current year) used in several places
- include FLTK Git revision in HTML and PDF docs
- include generation date and doxygen version
- replace special html footer which didn't work well with default footer
Conflicting demands arise in the implementation of class Fl_Xlib_Graphics_Driver
for drawing images with the XRender library :
1) Issue #163 leads to use a bilinear filter to draw-and-scale images.
2) This tends to blur the edges of drawn areas which is bad for tiled images
(that is because the edges get alpha values, even for an opaque source image).
This commit resolves the conflict adding a means to detect whether the library
is busy drawing a tiled image. If so, the bilinear filter is not applied, drawn areas
don't have blurred edges, resulting in a nice tiling.
With this commit, these test apps perform correctly:
- tiled_image is correct at all scaling factor values also when modified
to use a depth-3 or a depth-4 Fl_RGB_Image as tile;
- unittests - Drawing Images is correct at all scaling factor values;
- pixmap_browser scales correctly up and down JPEG and PNG images.
Remove build artifacts from normal builds (libs and executables).
These were never meant to be provided but forgotten to remove
after tests.
Try to build fltk.pdf (may be removed later)
Store fltk.pdf in 'public' folder to be available online in docs
and downloadable as "artifact"
Modifying test/tiled_image to make it use a depth-3 image for
tiling (rather than an Fl_Pixmap) shows the filter does require
to use PictOpOver as the render op in the XRenderComposite call.
Add an invisible box as resizable() to 'demogrp' to avoid bad resizing
behavior while the debug terminal is enabled. The old version would
disable some buttons including the 'exit' button if the window was
resized to a smaller size.
Simplify the popup menu (remove strcmp()).
Support different margin sizes on all four edges. Default margin
and gap size is now 0 (compatible with Fl_Pack).
Doxygen: move the description from the constructor to the class
declaration which constitutes a "description".
Make some methods virtual and/or 'const'.
Clarify demo programs, make them even more "FLTK style".
This work is based on the repository and latest commit:

Added Fltk (LGPL) license.
This widget is similar to Fl_Pack and supports either one row or one
column of widgets but has some more features. Test and demo programs
are included:
test/flex_login.cxx: simple "login window" demo program
test/flex_demo.cxx: slightly more complex demo program
The original demo programs can still be compiled and built with
the new widget provided you '#include <FL/Fl_Flex.H>'.
Backwards compatible methods are included (except debug()).
The original widget has been modified to match FLTK standards and
enhanced in several ways, including:
- support box frames
- add HORIZONTAL and VERTICAL enum values (as in Fl_Pack)
- add horizontal() method (as in Fl_Pack)
- use type() rather than internal 'direction' variable
- add standard widget constructor (x, y, w, h, label)
- add margin and gap accessors rather than hard coding constants
- improve test and demo programs
- add documentation
- replace <vector> with array as required by FLTK CMP
- rename camelCase method names, keeping old names for compatibility:
- change 'setSize(Fl_Widget*, int)' to 'set_size(Fl_Widget*, int)'
- change 'bool isSetSize(Fl_Widget*)' to 'int set_size(Fl_Widget*)'
- remove debug() method
- add a way to "unset" fixed size: set_size(Fl_Widget *, 0)
- add layout() method to force recalculation of children
- unify resizeRow() and resizeCol() methods to avoid code duplication
- improve widget size calculation.
