PyQt4示例从IDLE工作，但从npp执行时不工作 [英] PyQt4 example working from IDLE, but not when executed from npp

问题描述

我正在PyQt4中运行一个非常基本的示例.如下所示.我当时在挣扎着Enthought Canopy的安装，在cygwin Python的实施中挣扎，最后才一次安装了Python 2.7，Numpy 1.7.1和M​​atPlotLib 1.2.0.

I am running a very basic example in PyQt4. It is shown below. I was struggling with the Enthought Canopy installation, struggling with the cygwin Python implementation, and finally just installed Python 2.7, Numpy 1.7.1, MatPlotLib 1.2.0 one at a time.

当我从IDLE执行示例时，它工作正常.虽然当我尝试使用nppExec从Notepad ++执行它时，控制台窗口只是挂起.我看不到任何地方都弹出一个空窗口，也没有给出任何错误代码.

When I execute the example from IDLE, it works fine. Although when I try to execute it from Notepad++ using nppExec, the console window just hangs. I do not see a little empty window pop up anywhere, nor am I given any error codes.

• 我尝试了nppExec(-i)的交互模式和非交互模式
  • 我的nppExec命令是python "$(FULL_CURRENT_PATH)"
  • I tried interactive mode and non-interactive mode from nppExec (-i)
    • My nppExec command is python "$(FULL_CURRENT_PATH)"

    .

    • Python 2.7.4
    • notepad ++ 6.3.2

    • PyQt4 4.10.1

    • Python 2.7.4
    • notepad++ 6.3.2

    • PyQt4 4.10.1

    import sys
    from PyQt4 import QtGui
    
    
    def main():
    
        app = QtGui.QApplication(sys.argv)
    
        w = QtGui.QWidget()
        w.resize(250, 150)
        w.move(300, 300)
        w.setWindowTitle('Brian')
        w.show()
    
    sys.exit(app.exec_())
    
    
    if __name__ == '__main__':
        main()
    

  推荐答案

  在NppExec中，使用命令

  In NppExec, use the command

  CMD /C python -u "$(FULL_CURRENT_PATH)"
  

  代替

  python "$(FULL_CURRENT_PATH)"
