问题
Hey I am using the same old code for getting all the code outputs PyQT5 QTexBrowser GUI console, but I am also getting next line character ("\n") in all new lines.
Code URL - pipe the output of sys.stdout to text browser in pyqt
Below is the code I am using from above URL -
class Port(object):
def __init__(self, view):
self.view = view
def write(self, *args):
# self.view.append(str([*args]))
# self.view.append(str(*args).rstrip("\n").lstrip("\n"))
self.view.append(*args)
GUI Console Output -
Is there any way to remove "\n" from the args, Please suggest.
when I used below line, then I was able to see that there is "\n" in every new args.
self.view.append(str([*args]))
GUI Console Output with visible "\n" (* Ignore the numbers in lines as first character - that is part of user selection output.)
then I tried to do every possible way to remove like strip(), lstrip() etc, still didn't get success.
Below is the part of code, how I am redirecting run time output to QtextBrowser
self.execution_result = QtWidgets.QWidget()
self.execution_result.setObjectName("execution_result")
self.execution_rslt_saveresult_btn = QtWidgets.QPushButton(self.execution_result)
self.execution_rslt_saveresult_btn.setGeometry(QtCore.QRect(1220, 780, 131, 25))
self.execution_rslt_saveresult_btn.setObjectName("execution_rslt_saveresult_btn")
# ------------------------------------------------------------------------------------------------------#
# Console Output
# ------------------------------------------------------------------------------------------------------#
self.execution_rslt_textbrowser = QtWidgets.QTextBrowser(self.execution_result)
self.execution_rslt_textbrowser.setGeometry(QtCore.QRect(2, 1, 1371, 771))
self.execution_rslt_textbrowser.setObjectName("execution_rslt_textbrowser")
self.execution_rslt_textbrowser.setStyleSheet(
"""QTextBrowser {background-color: #000000;
color: #00FF00;
font: 11pt Courier new;}""")
self.execution_rslt_textbrowser.document().setPlainText(
"-" * 40 + '\n' + " Log starts from below line " + '\n' + "-" * 40)
# ------------------------------------------------------------------------------------------------------#
# Below line is sending run time output to GUI console
# ------------------------------------------------------------------------------------------------------#
sys.stdout = Port(self.execution_rslt_textbrowser)
Please anyone suggest what should I do here to remove "\n" from the outputlines.
also how to remove error AttributeError: 'port' object has no attribute 'flush'
Below is the working sample code with next line character issue. - For reference/debugging

self.view.append(*args)

回答1:
The append method adds an additional endline, the solution is to insert the text without adding it:
class Port(object):
def __init__(self, view):
self.view = view
def flush(self):
pass
def write(self, text):
cursor = self.view.textCursor()
cursor.movePosition(QtGui.QTextCursor.End)
cursor.insertText(text)
self.view.setTextCursor(cursor)
self.view.ensureCursorVisible()
回答2:
I write with command: sys.stdout.write("Append a line to console!"), it's all good, nothing redundant.
To delete the flush attribute error, just add to your Port class this override function:
def flush(self):
pass
Tested!
