PyGTK properties versus python properties -

-

when deriving gobject class in pygtk, can define gobject properties in c, using __gproperties__ dict, , do_get_property/do_set_property methods, described here in sub-classing gobject in python. note written before had @property decorator in python.

gobject properties have advantage can connect object's notify::property-name signal receive notification whenever property changes. other that, there reason use gobject properties instead of python's @property decorator?

why not use them? simplified version provided python bindings, defining gobject properties not different defining python properties.

having said that, there couple of advantages other notification. 1 i've made use of in past property setting in gtk.builder files. example, in ui file,

<object class="gtkimage" id="image">   <property name="stock">gtk-missing-image</property> </object>

sets stock property on image object when constructed builder class; if use gobject properties in custom widgets, can take advantage of too. behaviour more useful advent of property binding support in glade.

another potential advantage gobject properties' min/max limits , default values integers , floats, can useful ui-related properties.

i've been working on c++ code friend has written , following error have never seen before when compiling gcc4.6: error: use of deleted function ‘gamefsm_<std::array<c, 2ul> >::hdealt::hdealt()’ implicitly deleted because default definition ill-formed: uninitialized non-static const member ‘const h_t floppokergamefsm_<std::array<c, 2ul> >::hdealt::h’ edit: comes part of code using boost msm: boost webpage edit2: there no = delete() used anywhere in sourcecode. generally speaking, error mean? should looking when type of error occurs? i don't think other answers mentioning =deleted; syntax correct. error message says default constructor has been deleted implicitly . says why: class contains non-static, const variable, not initialized default ctor. class x { const int x; }; since x::x const , must initialized -- default ctor wouldn't initialize (because it's pod type). therefore, default ctor, need define 1 (and must ...

why need use because printers using tprinter prints weird hieroglyph @ beginning of printable area. my problem if send commands, nothing happens. esc e (#27 #69) - sending escape sequence didn't work expected. removed first letter , rest of string made bold. eg. hello -> ello . after changed esc e esc (#27 #69 #27), worked fine. example managed figure out, but... trying select character table "esc t n" (#27 #116 n), make "õäöü" work. command doesn't work. nothing happens! , command supported esc/p, esc/p 2 , 9-pin esc/p, should work fine. manual can found here . if has ever needed use esc/p commands maybe 1 can shed light how work them! thanks in advance! edit: in previous post asked more or less same question though answers how did send commands printer. (i'll change question there according answers!) i accepted ken's answer, because claimed way transferred commands wasn't best , got work escape command. problem after t...
