I want to write a Python/Gtk/Glade application that uses a C/C++
extension to render images of weather radar data. (Given that I'm
rasterizing large amounts of polar coordinate data, I'm quite certain
that I need to do the calculations in C/C++, rather than in Python.)
1) Which type of widget is best to use to contain these rendered
images?
Should I use a GtkPlotCanvas?
2) What's the simplest way to pass a pointer to the Gtk window to my
C/C++ extension?
It looks like I can pass "self._o" to my extension, and then my
extension would have the form:
static PyObject *_wrap_MyDraw(PyObject *self, PyObject *args) {
PyObject *canvas;
if (!PyArg_ParseTuple(args, "O!:MyDraw", &PyGtk_Type, &canvas))
return NULL;
MyDraw(GTK_PLOT_CANVAS(PyGtk_Get(canvas)));
Py_INCREF(Py_None);
return Py_None;
}
Is there any simpler way of doing this?
Thanks much!
