pyqt5 应用程序中的嵌入式 qtconsole 无法按预期工作
embedded qtconsole in pyqt5 aplication does not works as expected
我有一个相当大的项目,其中嵌入了 Jupyter QtConsole 4.4.2。
有关详细信息,请参阅:
https://github.com/3fon3fonov/trifon
现在,虽然有些进程是 running/finished,但我正在尝试向 Qtconsole 发送一些文本并将其用作输出屏幕(反之亦然,我希望 Jupyter 能够接收如果需要,可以控制 GUI,但这是我稍后必须处理的另一个问题。
问题是 "ConsoleWidget" 函数的某些固有功能
似乎不起作用,我找不到原因...
例如在我的主要 GUI 代码中:
ConsoleWidget_embed().push_vars({'fit':fit}) <-- WORKS!
ConsoleWidget_embed().clear() <-- Does not work!
ConsoleWidget_embed().print_text("Test string") <-- Does not work!
这是我嵌入到 Qtab 中的代码。
import numpy as np
import sys #,os
from PyQt5 import QtCore, QtGui, QtWidgets, uic
from qtconsole.rich_jupyter_widget import RichJupyterWidget
from qtconsole.inprocess import QtInProcessKernelManager
from qtconsole.console_widget import ConsoleWidget
class ConsoleWidget_embed(RichJupyterWidget,ConsoleWidget):
global fit
def __init__(self, customBanner=None, *args, **kwargs):
super(ConsoleWidget_embed, self).__init__(*args, **kwargs)
if customBanner is not None:
self.banner = customBanner
#self.font_size = 4
self.kernel_manager = QtInProcessKernelManager()
self.kernel_manager.start_kernel(show_banner=True)
self.kernel_manager.kernel.gui = 'qt'
self.kernel = self.kernel_manager.kernel
self.kernel_client = self._kernel_manager.client()
self.kernel_client.start_channels()
#self._execute("kernel = %s"%fit, False)
def stop():
self.kernel_client.stop_channels()
self.kernel_manager.shutdown_kernel()
self.guisupport.get_app_qt().exit()
self.exit_requested.connect(stop)
def push_vars(self, variableDict):
"""
Given a dictionary containing name / value pairs, push those variables
to the Jupyter console widget
"""
self.kernel_manager.kernel.shell.push(variableDict)
def clear(self):
"""
Clears the terminal
"""
self._control.clear()
# self.kernel_manager
def print_text(self, text):
"""
Prints some plain text to the console
"""
self._append_plain_text(text, before_prompt=False)
def execute_command(self, command):
"""
Execute a command in the frame of the console widget
"""
self._execute(command, False)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
main = mainWindow()
main.show()
sys.exit(app.exec_())
任何想法将不胜感激!
一切顺利,

您遇到的问题是每次键入 ConsoleWidget_embed()
时都会创建一个 ConsoleWidget_embed
,而不是创建一个 class 的对象并将其设置为class:
self.console_widget = ConsoleWidget_embed()
self.terminal_embeded.addTab(self.console_widget, "Jupyter")
# ...
def jupiter_push_vars(self):
global fit
self.console_widget.push_vars({'fit':fit})
self.console_widget.clear()
self.console_widget.print_text("Test string")
