GtkDatabox Files

2021-04-16
	* Release 1.0.0 
	* Added:
	- Convenience function to override the background-color of a databox: 
	  gtk_databox_set_bg_color().
	- Documentation in doc/html generated by ./configure --enable-gtk-doc
	- Icons for GtkDatabox and GtkDataboxRuler if enabled Glade, when
	  compiling with ./configure --enable-glade
	* Changed: 
	- Using libtool's versioning system, to avoid breaking binary compatibility
	  through every new minor-fixes release. Starting/resetting with 1:0:0 (see
	  'info libtool' on node *Versioning::).
	- Deprecated function gdk_cairo_create substituted with recommended code. 
	- Deprecated functions to get/set background substituted with recommended code.
	- Deprecated function gtk_adjustment_changed removed conditionally,
	  for GTK+ version >= 3.18.0.
	- Deprecated function gdk_cursor_new substituted with
	  gdk_cursor_new_for_display, in examples/*.c.
	- Deprecated function gtk_widget_override_background_color substituted
	  with new function gtk_databox_set_bg_color, in examples/*.c
	- Re-enabled deprecation warnings in Makefile.am.
	- log2 macro for _MSC_VER made private and hidden from GtkDoc.
	- Scrolling horizontally with Shift+ mouse middle button, instead of
	  using Alt.
	* Fixed:
	- Autoreconf warnings: INCLUDES ==> AM_CPPFLAGS
	- Seg-fault using deprecated macro G_TYPE_INSTANCE_GET_PRIVATE. Using
	  now *_get_instance_private() automatic functions.
	- All remaining compiling warnings removed.
	- Scrolling with mouse middle button or touch-pad.
	- examples/addremove wasn't working fine.
	- example/lissajous was drawing continously in the idle loop, now it
	  draws at 50 frames/sec with 'g_timeout'.
	* Removed:
	- libglade support, as it's based on GTK2.
	* Updated: 
	- Distribution files: TODO, README, Doxygen.
	- Minimum required versions for Pango and Cairo in configure.ac.
	- GSEAL_ENABLE not needed anymore in Makefile.am.
	- gtkdatabox_marshal.c/h regenerated.
	- glade/gtkdatabox.xml widget catalog definition for use with Glade3.
