问题 I wanted to set QCullFace to FrontAndBack and that is why I wrote this: from PySide2.Qt3DRender import Qt3DRender cull_face = Qt3DRender.QCullFace() cull_face.setMode(Qt3DRender.QCullFace.FrontAndBack) render_pass = Qt3DRender.QRenderPass() render_pass.addRenderState(cull_face) The code above should set CullFace globally. But it does not. What did I do wrong? 回答1: I assume that the python binding does not change how Qt works in C++. So you probably have a Qt3DWindow somewhere (unless you

问题 I have an MVC web application. The URL for a particular area is coming in as: http://localhost/General/Bpa%3fapplication%3dTrf%23/GeneralInputs This causes a "The resource cannot be found." error. However, if I change the URL to http://localhost/General/Bpa?application=Trf#/GeneralInputs then everything works. I can see from using some route debugging tricks that the controller in the first case is: "Bpa?application=Trf#", whereas the second one is: "Bpa", which is correct. How can I account

问题 I have a script below that gives the closest 2 values to a given sum. It also iterates through a list of given sums and after each iteration removes the numbers that have already been used. I need to modify this script so that it produces a necessary amount of values closest to each sum, rather than 2. The script needs to accept float values and cannot re-use values. Effectively it needs to pick the most efficient set closest to target, update the set to remove values used, then move on to

问题 Is there any documentation for the Spotify Web API as to which characters are valid when searching? For example "Macklemore & Ryan Lewis" needs the & to be url encoded in order for the request to work. The character ":" is completely invalid it seems. In order to search for an album like "Pink Friday: Roman Reloaded", I have to remove the : completely from the String. Even URL encoding it doesn't work. This probably was to do with the fact that : seems to be used to separate the fields of the

问题 This is my first post. I need string array validation such like below. [Required(ErrorMessage = "Content name is required")] public string[] ContentName { get; set; } I found a post which has the same situation. This answer and following code helped me so much and I could solve my problem. public class StringArrayRequiredAttribute : ValidationAttribute { protected override ValidationResult IsValid (object value, ValidationContext validationContext) { string[] array = value as string[]; if

问题 I have an adapter and a spinner view which is set to use the adapter for it's entries. I'm adding items to adapter from a list of all files in /assets/ folder, I found that this task takes very long time (even about 2 seconds for a list of 2 files on a 1.5Ghz phone!). Then I came up to use a worker thread to gather my list and not block UI thread. here is my code: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.settings);

问题 I've been trying to figure out how to divide the contents of a TkInter entry box with a number (a float, to be precise). I looked it up on Google, and I found nothing that answered my question, other than doing .get() for getting a number from a entry. I want to have a number already there (or have a static variable) that I can divide to get the results I need. Any help would be appreciated! Thanks a billion!! :D P.S. Here's the website results I saw before I posted this question: Results of
