144 ADDITIONS: constructor in String_vec which accepts value/line ending pair of any std::string or c-string type; interface for text size measurement in Text, Text_module, W_caption; constructor for creating Vector2D out of Point2D explicitly; example application slightly better, but still lame; CHANGES: improvement and cleanup of the miscellaneous_widgets.cpp file;

143 FIXES: example application now fixed and up to date with the new naming convention of the library; get_PKgraphics_provider() changed to get_Graphics_provider();

140 CHANGES: file names of the code files in PKini folder have been changed to follow the changed naming convention of the code identifiers; such change will be applied to the rest of the library as well;

138 some files

137 FIXES: cleanup of PKstring.cpp;

136 ADDITIONS: test_all method with ostream& argument, so that errors do not have to be printed to tests.txt file; macro definitions for testing exceptions;

135 ADDITIONS: the class PKmultiline_string<charT> which inherits from vector<basic_string<charT> >; this is mainly to allow calling string operations on string vectors as member functions of string vector (via '.'), rather than via 'PKstr::'; PKtext::set_line function has been added, it was an obvious lacking feature; CHANGES: PKstr::vec_size_type and PKstr::size_type changed to direct usage of size_t, because the typedefs cause unnecessary burden and name clashes (e.g. size_type of PKmultiline_string<charT>::size_type clashed with vector<basic_string<charT> >::size_type), while being always used by the compiler manufacturers (otherwise their compilers would be useless); PKstring_vec typedef is now PKmultiline_string<Uint16> rather than vector<basic_string<Uint16> >; it is a cosmetic change, since PKmultiline_string<Uint16> inherits publicly from vector<basic_string<Uint16> >; FIXES: PKstr::to_string, PKstr::substr, PKstr::get_line_pos, PKstr::get_pos, PKstr::append, PKstr::length and PKstr::insert are unit-tested now; PKstr::to_basic_string now correctly does NOT append an extra newline at the end of resulting string, which makes it symmetric with to_string_vec and consistent with the rest of the code; PKstr::end fixed and more unit-tested;

134 FIXES: PKstr::substr has been fixed;

133 FIXES: slightly optimized build (header inclusion); PKstring has been tested a bit more, a bug in to_string_vec was detected and fixed (the function was ignoring the last new line char if it was at the end of the string); the PKstr::print_wide was fixed (the new line after the last line is no longer added);

132 ADDITIONS: it is now possible to plug a custom text clipboard implementation into PKgui; FIXES: scaling widget without 'image' property now does not crash in PKwidget; the documentation of PKeditbox_listener no longer lies; PKw_slider and PKw_slider_number_selector now correctly take focus themselves before giving it to children and they draw a focus indicator; PKtext::insert was crashing when caller inserted something to a text with no string lines;

130 FIXES: an argument with coordinates added to PKextended_widget_factory::create_slider_number_selector;

126 FIXES: crash of PKw_slider::update_display function when 'image' properties were null; PKfilled_shape drawer now has a correct copy constructor and operator=; PKextended_widget_factory::apply_res was not assigning the right images to slider handle;

125 FIXES: is_usable global functions now all check that there is a non-null object pointer by smart pointers (some of them crashed); the documentation of PKwidget does not lie any more (particularly set_show and set_show_frame functions); various set_*texture_unit functions in PKwidget, PKw_button and PKw_checkbox now do not crash when the 'image' property is null; PKwidget_factory now avoids creating texture units for widgets when they have null image property (removal of unnecessary computation); CHANGES: PKw_slider is now one of the widgets that can take focus; ADDITIONS: PKw_slider may now be moved with keyboard arrows, if focused;
