问题 I'm very new to Qt (specifically PySide) and I'm trying write a script that loads an animated gif from file into a QByteArray and then into a QMovie. The reason for going from file to the QByteArray is because I cannot keep that gif file in memory. I want to be able to store the animated gif in such a way that it can be written out to a JSON file later (hence the QByteArray). I've tried using ekhumoro's answer from here and although no errors showed up, the animated gif also doesn't show up.

问题 I have large time-traces that must be inspected visually, so I need a fast scrolling tool. How can I achieve the fastest Maplotlib/Pyside scrolling? Right know, I added a PySide scroll-bar to a MPL figure and update the x-range of the plot with set_xlim() method. This is not fast enough especially because in the final application I have at least 8 time-traces in different subplots that must all scroll together. A figure of the plot is attached. Is there room for improvement? Here I attach the

问题 Qt interfaces currently look horrible on a retina display as they scale up.Its possible to use an Info.Plist for a complied application but does anyone have a solution for dynamic python such as interfaces created in PySide? 回答1: You didn't say what Qt version you're working with. Retina support is best in the latest release, Qt v5.1. but v5.0's is also pretty good. If you're still on Qt v4.8, you'll have to manually apply patches to enable high DPI. High DPI mode is controlled by the

问题 I am building a QWidget in PySide, and running into an issue when trying to share data between pages. To summarize I utilize user inputs from earlier pages to construct a list of custom objects, which I need to share with the following page. At the beginning of my code I construct a custom object, with an attribute called .name (among other attributes) class MyCustomClass(): def __init__(self, name, other_attributes) self.name = name ...set other attributes In my QWizard I open a file and

问题 I am working on a project where I want to confirm the existence of a host on a local network. In the QtNetwork package in Qt, the QHostInfo::lookupHost method is a convenient way of searching for a host without needing to implement any kind of pinging or being dependent on a ping system call. Its asynchronous call makes it convenient to create a dialog waiting for the call to return with a slot in either the dialog or the main program to handle the return. From Qt's Documentation for
