拖放事件后更新 PyQT 中的标签文本
Updating label text in PyQT after drag & drop event
我只是在 Python 中速成 UI，但似乎我遇到了这堵有趣的墙，我希望得到一些帮助。
我的代码是：
from PyQt5.QtWidgets import QMainWindow, QApplication
import sys
from subprocess import check_output
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtCore import *
import json
import time
class MainWidget(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("GAINWARD EDGE Antivirus")
self.resize(504, 590)
self.setAcceptDrops(True)
self.pushButton_2 = QtWidgets.QPushButton(self)
self.pushButton_2.setGeometry(QtCore.QRect(170, 520, 141, 21))
self.pushButton_2.setObjectName("pushButton_2")
self.LFileName = QtWidgets.QLabel(self)
self.LFileName.setGeometry(QtCore.QRect(210, 50, 91, 21))
self.LFileName.setFrameShape(QtWidgets.QFrame.StyledPanel)
self.LFileName.setLineWidth(19)
self.LFileName.setObjectName("LFileName")
self.LCrowdStrike = QtWidgets.QLabel(self)
self.LCrowdStrike.setGeometry(QtCore.QRect(70, 190, 131, 16))
self.LCrowdStrike.setObjectName("LCrowdStrike")
self.LHash = QtWidgets.QLabel(self)
self.LHash.setGeometry(QtCore.QRect(210, 90, 91, 21))
self.LHash.setFrameShape(QtWidgets.QFrame.StyledPanel)
self.LHash.setLineWidth(19)
self.LHash.setObjectName("LHash")
self.LMetaDefender = QtWidgets.QLabel(self)
self.LMetaDefender.setGeometry(QtCore.QRect(70, 240, 131, 16))
self.LMetaDefender.setObjectName("LMetaDefender")
self.LVirusTotal = QtWidgets.QLabel(self)
self.LVirusTotal.setGeometry(QtCore.QRect(70, 290, 131, 16))
self.LVirusTotal.setObjectName("LVirusTotal")
self.StatCrowd = QtWidgets.QLabel(self)
self.StatCrowd.setGeometry(QtCore.QRect(260, 180, 111, 41))
self.StatCrowd.setObjectName("StatCrowd")
self.StatMeta = QtWidgets.QLabel(self)
self.StatMeta.setGeometry(QtCore.QRect(260, 230, 111, 41))
self.StatMeta.setObjectName("StatMeta")
self.StatVirus = QtWidgets.QLabel(self)
self.StatVirus.setGeometry(QtCore.QRect(260, 280, 111, 41))
self.StatVirus.setObjectName("StatVirus")
self.retranslateUi(self)
QtCore.QMetaObject.connectSlotsByName(self)
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
self.pushButton_2.setText(_translate("Dialog", "Exit"))
self.LFileName.setText(_translate("Dialog", "FileName"))
self.LCrowdStrike.setText(_translate("Dialog", "CrowdStrike Falcon:"))
self.LHash.setText(_translate("Dialog", "Hash"))
self.LMetaDefender.setText(_translate("Dialog", "Metadefender:"))
self.LVirusTotal.setText(_translate("Dialog", "VirusTotal:"))
self.StatCrowd.setText(_translate("Dialog", "Status1"))
self.StatMeta.setText(_translate("Dialog", "Status2"))
self.StatVirus.setText(_translate("Dialog", "Status3"))
def dragEnterEvent(self, event):
if event.mimeData().hasUrls():
event.accept()
else:
event.ignore()
def foobar():
ui.LFileName.setText(f)
ui.LHash.setText("???")
ui.StatCrowd.setText(crowdStrikeStatus)
ui.StatMeta.setText(metaDefenderStatus)
ui.StatVirus.setText(virusTotalStatus)
def dropEvent(self, event):
files = [u.toLocalFile() for u in event.mimeData().urls()]
for f in files:
out = check_output(["C:\Users\lilra\AppData\Local\Programs\Python\Python39\python.exe", "C:\Users\lilra\Desktop\dev\pyqt\VxAPI\vxapi.py", "scan_file", f"{f}", "all"])
crowdStrikeName = json.loads(out)['scanners'][0]['name']
crowdStrikeStatus = json.loads(out)['scanners'][0]['status']
if "no-result" in crowdStrikeStatus:
crowdStrikeStatus = "No detection [OK]"
print(f"{crowdStrikeName}: {crowdStrikeStatus}")
metaDefenderName = json.loads(out)['scanners'][1]['name']
metaDefenderStatus = json.loads(out)['scanners'][1]['status']
if "clean" in metaDefenderStatus:
metaDefenderStatus = "No detection [OK]"
print(f"{metaDefenderName}: {metaDefenderStatus}")
virusTotalName = json.loads(out)['scanners'][2]['name']
virusTotalStatus = json.loads(out)['scanners'][2]['status']
if "no-result" in virusTotalStatus:
virusTotalStatus = "No detection [OK]"
print(f"{virusTotalName}: {virusTotalStatus}")
VirusTotal.setText('Hello, world!')
if __name__ == '__main__':
app = QApplication(sys.argv)
ui = MainWidget()
ui.show()
splash = QSplashScreen()
splash.setPixmap(QPixmap('obbac2wjcpvenbtcg8zi.png').scaled(770, 830))
splash.show()
splash.showMessage('<h1 style="color:white;">Gainward EDGE Antivirus Initializing...</h1>',
Qt.AlignTop | Qt.AlignHCenter, Qt.white)
time.sleep(1)
splash.hide()
sys.exit(app.exec_())
所以在 drop 事件之后，它可能应该做这样的事情：
def foobar():
ui.LFileName.setText(f)
ui.LHash.setText("sample API response text")
ui.StatCrowd.setText(crowdStrikeStatus)
ui.StatMeta.setText(metaDefenderStatus)
ui.StatVirus.setText(virusTotalStatus)
但我很难做到这一点。
回顾一下，我在文件的拖放事件后进行 API 调用，然后尝试使用 API 响应的解析结果更新文本标签。
这将有效：
class MainWidget(QMainWindow):
...
def dragLeaveEvent(self, event):
self.foobar(file_info=('-', '-'))
def dragEnterEvent(self, event):
if event.mimeData().hasUrls():
event.accept()
file = event.mimeData().urls()[0]
file_info = self.get_file_info(file=file)
self.foobar(file_info=file_info)
else:
event.ignore()
@staticmethod
def get_file_info(file):
hasher = hashlib.md5()
with open(file.toLocalFile(), 'rb') as f:
hasher.update(f.read())
filename = file.fileName()
_hash = hasher.hexdigest()
return filename, _hash
# UPDATE UI
def foobar(self, file_info):
self.LFileName.setText(file_info[0])
self.LHash.setText(file_info[1])
