Hi iko...@earthlink.net, On Sat, 26 Mar 2011 20:45:53 -0700 (GMT-07:00) you wrote: Yes. You are casting the _RESULT_ of a _CALL_ to ReadData into a GSourceFunc, but ReadData returns void. This produces utterly random results. Yes, I believe I made a mistake here. I was not in front of my developmental machine, so... I think the ReadData() is returning gboolean. Perhaps, but a gboolean is most definitely not the same as a GSourceFunc. So I shall reiterate: g_timer_add_seconds( 1, (GSourceFunc) frame-ReadData(), NULL ); ^^ You are casting the _RESULT_ of a _CALL_ to ReadData into a GSourceFunc, but ReadData returns bool. This produces guaranteed illegal results. The second argument of g_timeout_add_seconds is a function pointer, and requires that you pass it a simple C function reference _without_ the call syntax. Unless you're now going to say that you'd misremembered that too, and the actual code doesn't have the () after the frame-ReadData in the line I re-quoted. It would really help us to help you if you had posted your actual code rather than a misremembered vague approximation.

To make that finally clear, thats why the signal functions pass a data

static function:
class CFrame {
static gboolean ReadData(CFrame* me);
};
/* ... */
g_timeout_add_seconds(1,(GSourceFunc)CFrame::ReadData,frame);

static frame_ReadData(CFrame *f) { return f-ReadData(); }
Actually and fully you will need
static gboolean frame_ReadData(CFrame* f) { return f-ReadData(); }
Note that frame_ReadData is a C function, so that static means something
different than in the C++ class context.
Actually nothing speaks against using an extern function, though
it might make not much sense to export such a simple, locally used
function.

You should most properly use a plain function with C linkage as the
callback. If you want to access instance (non-static) data you need to
pass in an instance pointer; and if it needs to access private data it
should be made a friend.
Basically what you want is something like this:
// *** header file ***
extern C gboolean cframe_read_data(void* data);
class CFrame {
...
public:
...
gboolean ReadData();
};
// *** implementation file ***
gboolean cframe_read_data(void* data) {
return static_castCFrame*(data)-ReadData();
}
int main() {
...
CFrame* cf = new CFrame;
g_timer_add_seconds( 1, cframe_read_data, cf);
...
}
This is all very basic C/C++

I can't build Gtk+ 3.0.6 ( 3.0.5) from the source against OpenSUSE binaries

I have OpenSUSE binaries in c:\gtkmm3\ . But Gtk+ 3.0.5 builds just fine
against binaries from gnome project's ftp if I add libmsvcrt.a from MinGW into
gtk-demo project. Also I had to change path to demos in main.c around line 48
as it points to old gtk.
3)
I was able to link and run successfully very simple tests against OpenSUSE
binaries for Glib with MS VC++ 2008. Although I had also to link against

library as was correctly pointed by Fan. Without it, simple IO with g_fopen()

RE: Gtk+ 3.0 and MS Windows
Just in case someone is following :-)
I was able to successfully build GTK+ 3.0.6 using MS VC++ 2008 Express using
underlying OpenSUSE win32 binaries. I had to play around with nm.exe and
lib.exe (MS proprietary tool) to generate missing dot def files as a usage of
gcc libraries (.dll.a) resulted in a weird behavior (like import of symbols
from improper dll as I reported before).
Gtk-demo.exe runs mostly okay though toolbar icons are not redrawn after menu
popup and it dumps sometimes warnings. Tool Palette demo is glitchy in sense of
icons. Entry, Icon View, Text Widget demos don't show up at all. Pickers demo
fails with GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser'
is not installed
I don't have much spare time, but I'll try to summarize what should be done to
utilize cross-compiled binaries (like from OpenSUSE) to build stuff using MS
VC++. I guess it would be substantial time saver not to manually build
dependencies under MS Windows.
Here is the python script I used to convert libraries from gcc to MSVC format:
