How can you bind exceptions with custom fields and constructors in pybind11 and still have them function as python exception?

阅读更多关于 How can you bind exceptions with custom fields and constructors in pybind11 and still have them function as python exception?

问题 This appears to be a known limitation in pybind11. I read through all the docs, whatever bug reports seemed applicable, and everything I could find in the pybind11 gitter. I have a custom exception class in c++ that contains custom constructors and fields. A very basic example of such a class, trimmed for space is here: class BadData : public std::exception { public: // Constructors BadData() : msg(), stack(), _name("BadData") {} BadData(std::string _msg, std::string _stack) : msg(_msg),

Parsing User Defined Types Using PyArg_ParseTuple

阅读更多关于 Parsing User Defined Types Using PyArg_ParseTuple

问题 How to parse userdefined types (or types from an existing non-standard library) using PyArg_ParseTuple ? 回答1: Instead of using the plain O format, as Martijn suggested, I normally prefer using the O& format. It allows you to pass a function that will be called to convert any PyObject* to an arbitrary C (double) pointer. Here is some example usage, in which I'm converting a passed value to a pointer to my own object type: /** * This method should return 0 if it does not work or 1 in case it

I'm looking at using python (CPython) in my program to both allow user scripting in my environment and to allow me to use pyside, the qt bindings for c++ to create the GUI for my application. These can be effectively separated with the idea that the GUI python code can later be compiled away for speed (if that

Is there a way to perform a mouseover (hover over an element) using Selenium and Python bindings?

阅读更多关于 Is there a way to perform a mouseover (hover over an element) using Selenium and Python bindings?

Reading here , there apparently used to be a RenderedWebElement class with a hover method. It, however, was exclusively made for Java (I have searched the Python bindings documentation to no avail) and has since been deprecated for Java. A hover can't be performed using action_chains nor by using a WebElement object either. Any ideas as to how to do this for Python? I have been here but it uses RenderedWebElement and hence doesn't help too much. I am using: Python 2.7, Windows Vista, Selenium 2, Python Bindings EDIT: There is a method mouse_over for a selenium.selenium.selenium object but I
