When returning a type from a plugin (freebasic), what is the major and minor fields used for?
"RT(n,ma,mi)"

hType=RT(name,major,minor) RT means [r]egister [t]ype
not
STR(handle,value) et [t]ype [r]esult
you can define your own major,minor numbers
can be usefull if two plugins shares a user defined data type
but i have never tryed to share a data type between two plugins
Joshy
an other plugin can fetch a preview registered user defined data type
FetchStructure as function (THIS_REGISTRY, _
nam as zstring ptr, _
vMajor as integer , _
vMinor as integer) as integer

why are you trying to return a pointer to a library type? this helps when you show us what your trying to do

if you return a type B4GL will read the type from the DLL memory so you must return the address of the type
your_type.member=123
STR(handle,@your_type) ' @ will return the address of your_type

i am trying to do something equivalent to "World=NewtonCreate()" from djlinux's plugin
or "handle = newSprite()" if that makes sense?

SFR(value)
means et [f]loat [r]esult
STR(handle,@type]
means et [t]ype [r]esult

What kind of types can you return? are their restrictions? im asking these in terms of c++...

so far this is what i have for the function
private sub GtkWindowNew(THIS_RUNTIME)
Dim As GtkWidget Ptr Win = Gtk_Window_New(Gtk_Window_TOPLEVEL)
STV(0,@Win)
end sub
and i am getting an error with registering it
RTF(GtkWindowNew,@GtkWindowNew,gtkWidget)
and this is how i am registering the type, i don't know if i am doing it right or if i even should do it at all
RTBPF(GtkWidget)

"dim as GtkWidget Ptr win" is a pointer and a pointer is in basic4gl simple an 32bit integer
' use this
SIR(win)
and
RIF(GtkWindowNew,@gtkwindownew)
or do you have registered the whole GtkWidget as TYPE?

so if i return the address when i hand it back to the plugin with a different function could i use it just like i would the pointer?

by the way, it's a nice idea to use GTK in B4GL but it won't work
the gtk "messageloop" will block B4GL or how you would get the gtk window messages?
i mean after "gtk_main( )" your plugin will block B4GL
Joshy
sorry if i'm wrong
