[graph] fix for intel-win32-7.1-vc6
by Joaquín Mª López Muñoz 23 Sep '04

23 Sep '04

This trivial fix takes care of issues having to do with BOOST_NO_STDC_NAMESPACE, which impact the test layout_test on intel-win32-7.1-vc6. OK to commit?

Workaround macro for intel-7.1-vc6-*
by Jonathan Brandmeyer 23 Sep '04

23 Sep '04

What is the correct BOOST_WORKAROUND macro for this platform? I'm currently using #ifdef ((BOOST_WORKAROUND( BOOST_INTEL_CXX_VERSION, == 710)) && defined(_WIN32)) which does not seem to be enough. Thanks, -Jonathan

Wouldn't you process the pen objects, etc. when handling the drawing event. Instead of storing a pen handle for each line (which IMHO is overkill), you would do something like: namespace gdi = boost::gdi; namespace colors = boost::gdi::colors; namespace units = boost::units; void draw( gdi::canvas & c ) { gdi::pen mypen( colors::lightskyblue ); gdi::font myfont( "Times New Roman", units::picas( 12 )); c.set_units( units::picas ); c.attach( mypen ); c.attach( myfont ); c.set_color( colors::red ); c.draw_string( 1, 1, "Hello World!" ); // uses myfont + colors::red c.line( 10, 10, 10, 15 ); // uses mypen c.line( 10, 15, 15, 15 ); // uses mypen c.line( 10, 10, 15, 15 ); // uses mypen c.attach( gdi::default_pen( colors::red )); // ... } Likewise, with the component framework (windows, widgets), it should be possible to implement windowless components that do not have a handle attached to them. This would be useful when implementing the layout managers. Handling an event should not be bound to the component that generates them. For example, MFC provides handling the exit message on the application object and not the main window object. This would then allow you to bind events to a graphical object without using a window handle. IMHO, line information should be separate from its colour, thickness, etc. Otherwise, you would need to do something like: class line_object { private: unit x1, y1, x2, y2; gdi::pen * pen; public: void draw( gdi::canvas & c ) { c.attach( *p ); c.draw_line( x1, y1, x2, y2 ); } }; which wastes a call to attach the pen each time. This is especially bad if you have 1000s of lines (e.g. drawing a hilbert curve or serpinski's triangle fractal with a fractal depth of 4 or more).

[serialization] white cells (continued)
by Stefan Slapeta 23 Sep '04

23 Sep '04

I don't know if that's the same as in boost.python but the serialization library now shows up white cells, too: http://tinyurl.com/3pvzv It's remarkable that all these are results of compile or compile-fail tests and the tests would succeed if they are reported correctly. I attach an excerpt of my bjam.log: please have a look at it, it seems to me that everything is correct except the interpretation of the results.

[assign] fixes for msvc, msvc-stlport and vc7
by Joaquín Mª López Muñoz 23 Sep '04

23 Sep '04

The attached fix makes all tests compile for msvc (not all run, though) and hopefully also for the other two toolsets (can't try myself.) Two changes applied, both in list_insert.hpp: 1. MSVC++ 6.0/7.0, in the presence of a templated memfuns, interprets additional overloads as if they were specializations of the former (which is not legal C++, AFAIK). This introduces problems with the copy ctors of list_insert, which can be workarounded by a) making the template copy ctor accept const references b) declaring and defining the plain default copy ctor of list_insert *after* the templated copy ctor. 2. list_insert::operator()(T t) has been changed to accept a const reference instead. With these changes, all tests build, though three of them crash at run-time (list_inserter, list_of and multi_index_container) I've checked the changes with a compiler other than MSVC (GCC 3.2), seems like nothing ain't broken. I've got two questions: 1. Could somebody (the author, I guess) validate these changes for commit? 2. list_inserter follows a strange convention (IMHO) of not forcing template params to be const references in its various copy ctors and assignment operators, for instance: list_inserter( Function fun ); template< class T > list_inserter& operator=( T r ); Any reason for this approach? I don't know if this can pose problems, but to me having these qualified with const & seems like the usual way.
