问题 I am learning GUI in Java, and for that I have created a demo program: import java.awt.*; public class FrameDemo extends Frame { public FrameDemo(){ super("Frame Demo"); setSize(200, 200); setVisible(true); } public static void main(String args[]){ new FrameDemo(); } } It was compiled successfully. But when I tried to execute the program, I found the following error: Exception in thread "main" java.awt.HeadlessException at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java

问题 I was just testing an example from Numerical Methods in Engineering with Python . from numpy import zeros, array from math import sin, log from newtonRaphson2 import * def f(x): f = zeros(len(x)) f[0] = sin(x[0]) + x[1]**2 + log(x[2]) - 7.0 f[1] = 3.0*x[0] + 2.0**x[1] - x[2]**3 + 1.0 f[2] = x[0] + x[1] + x[2] -5.0 return f x = array([1.0, 1.0, 1.0]) print newtonRaphson2(f,x) When I run it, it shows the following error: File "example NR2method.py", line 8, in f f[0] = sin(x[0]) + x[1]**2 + log

问题 I tried to do some operation ( setParent ) on an object in Python (an instance of a class which inherits from a different class - to be specific, QtGui.QLabel ), but during runtime the above error was raised. The object itself has had some fields with actual content (verified on debug), but from some reason I couldn't "use" it. What does the error mean and how can I fix it? For some additional information, I shall say that the object was returned from a static method before I tried to do this

问题 Trying to use Select2 and getting this error on multiple item input/text field: "query function not defined for Select2 undefined error" 回答1: Covered in this google group thread The problem was because of the extra div that was being added by the select2. Select2 had added new div with class "select2-container form-select" to wrap the select created. So the next time i loaded the function, the error was being thrown as select2 was being attached to the div element. I changed my selector...

问题 #include <queue> using namespace std; class Test{ int *myArray; public: Test(){ myArray = new int[10]; } ~Test(){ delete[] myArray; } }; int main(){ queue<Test> q Test t; q.push(t); } After I run this, I get a runtime error "double free or corruption". If I get rid of the destructor content (the delete ) it works fine. What's wrong? 回答1: Let's talk about copying objects in C++. Test t; , calls the default constructor, which allocates a new array of integers. This is fine, and your expected
