问题描述

Pyqt 中是否有类似的函数 PyOnDemandOutputWindow?此函数将控制台输出重定向到一个单独的窗口.

Is there a similar function PyOnDemandOutputWindow in Pyqt? This function redirect the console output to a separate window.

推荐答案

可以将 sys.std[out|err] 替换为将所有输出写入到例如一个 QPlainTextEdit.一个非常基本的例子:

It is possible to replace sys.std[out|err] with a wrapper that writes all output to e.g. a QPlainTextEdit. A very basic example:

class StdoutWrapper(object):
    def __init__(self, outwidget):
        self.widget = outwidget
        self.widget.setReadOnly(True) # assuming QPlainTextEdit
        self.widget.hide()

    def write(self, s):
        self.widget.show()
        self.widget.appendPlainText(s) # again assuming QPlainTextEdit

还有其他地方:

import sys

sys.stdout = StdoutWrapper(yourwidget)
# similar for stderr, but you might want an error dialog or make 
# the text stand out using appendHtml
