Recently there was idea about "spirit-like" dialog sublanguage
implemented in c++. I still can't get why someone may need
it ?
Spirit is forced to use such language to build QUOTED code, which
works only when parsing occur. In case of GUI lib
sutiation is different :
We are not building code, but tree of gui objects placed in
2d (+z order). Sure boost::gui should deal with actions,
but generally they are much more compicated than spirit ones
and can't be easyly implemented by binders/bll/phoenix.
Besides, average gui control has a lot of properties which
may change in runtime. Would be convenient and
effective to fill/change such properties using spirit like
language ?
Why invent new shape for wheel ? :
void my_action( component & sender )
{
show_dialog( "sender is " + sender.title() );
}
main()
{
window w;
w.title("sample boost application");
w.width( 400 );
w.height( 200 )
button b;
b.title("click it!");
b.on_click.connect( &my_action );
w.insert( b );
b.align( alignment::vcenter | alignment::hcenter );
progress_bar pb;
pb.align( alignment::bottom );
pb.min( 0 );
pb.max( 100 );
pb.step( 5 );
pb.smooth( true );
w.insert( pb );
w.show(); //or w.show_modal();
window::main_loop();
}
regards,
bohdan
