问题 I'm very new to Python and need an approach for accomplishing an important function I've done before in macro-scripting languages: I have a Python program that will be processing a screengrab image using pyscreenshot. In order to feed pyscreenshot the necessary x1, y1, x2, y2 coordinates to create the image, I need the user to define the portion of the screen by drawing a rectangle around it. Think "snipping" tool in Windows and cmd+shift+4 in OSX. I am open to using any BSD module necessary

问题 In a Flutter project I create a pdf document. I can save the document in the path of the app. But the user has no access to it.

Can a MongoDB collection have inside it another collection?

由 妖精的绣舞 提交于 2020-01-21 04:19:04
问题 I need to store a recursive tree structure. A linked list. So all the objects are the same. Each has a pointer to a parent object and each has an array of child objects. Can I store such a structure in Mongo. i.e. A Mongo collection of parent objects, each object holds within it a Mongo collection of child objects. $a = $MyCollection->findOne(**some conditions)->Childs->find(...) 回答1: You cant store collections in collections. But you can store ids that reference objects in other collections.

Where to store large application data on android devices?

由 自闭症网瘾萝莉.ら 提交于 2020-01-13 09:17:27
问题 I'm currently facing a problem where I should store my object structure on the android device. The usecase: I'm starting a call to an applicationserver (with the great help of AsyncTask), get a well known response (xml-response) from the server, parse the data and transform it finally into my object structure (highly complex class diagram with many associations between the classes). So far it's working, thanks to the great XMLPullParser ;) I'm wondering where to store (and of course share)
