http://doc.qt.io/qt-5/qmenubar.html#nativeMenuBar-prop as an example:import random, string from PyQt5 import QtWidgets, QtCore class MainWidget(QtWidgets.QWidget): '''центральный виджет''' def init(self): super().init() layout = QtWidgets.QFormLayout() self.text = QtWidgets.QTextBrowser() layout.addWidget(self.text) self.setLayout(layout) def cmd(self): [self.text.append(str(a)) for a in range(20)] class MainWindow(QtWidgets.QMainWindow): def init(self): QtWidgets.QMainWindow.init(self) self.central = MainWidget() self.setCentralWidget(self.central) self.menu_bar() self.tool_bar() self.status_bar() self.show() def menu_bar(self): self.menuBar().setNativeMenuBar(False) exit_menu = self.menuBar().addMenu('&Exit') exit_ = QtWidgets.QAction('&Exit', self) exit_.setShortcut(self.tr("Ctrl+Q")) exit_.setStatusTip(self.tr("Exit the application")) exit_.triggered.connect(self.close) exit_menu.addAction(exit_) def tool_bar(self): toolbar = QtWidgets.QToolBar(self) self.addToolBar(QtCore.Qt.BottomToolBarArea, toolbar) action = QtWidgets.QAction('Toolbar text', toolbar) action.triggered.connect(self.central.cmd) toolbar.addAction(action) def status_bar(self): sb = QtWidgets.QStatusBar() self.setStatusBar(sb) ed = QtWidgets.QPushButton('StatusBar text') self.statusBar().addPermanentWidget(ed) ed.clicked.connect(lambda: self.statusBar().showMessage(random.choice(string.ascii_letters))) q = QtWidgets.QApplication([]) m = MainWindow() q.exec_()

You can watch class. QStackedWidget♪ This class allows for the addition of a few viewpoints in the stack, and then it's the one you need to change. index♪

To put the window in the right bottom corner, you have to start shaping the window, then move it. In order to eliminate the milling, the window should initially be removed from the screen:import sys from PyQt5.QtWidgets import QApplication, QWidget def move2RightBottomCorner(win): screen_geometry = QApplication.desktop().availableGeometry() screen_size = (screen_geometry.width(), screen_geometry.height()) win_size = (win.frameSize().width(), win.frameSize().height()) x = screen_size[0] - win_size[0] y = screen_size[1] - win_size[1] win.move(x, y) if name == 'main': app = QApplication(sys.argv) w = QWidget() w.move(w.width() * -3, 0) # чтобы не мелькало w.show() move2RightBottomCorner(w) sys.exit(app.exec_())

in linux, everything should be set out of packages. Get the team apt-get. Like apt-get install qtcreator. Apt-cache search pyqt

For the facility QAction There is a special event describing the operation of the upgrade of the statusbar:QtCore.QEvent.StatusTip Accordingly, the filter design code will look like:class _FilterConstructor(QtCore.QObject): def init(self, parent): super().init(parent) def eventFilter(self, obj, _event): if _event.type() == QtCore.QEvent.StatusTip: return True else: return QtCore.QObject.eventFilter(self, obj, _event)

It's very strange that you're crashing into QT. Thus, in most cases, there is either a Exception from which the problem is easily understood. Either QT falls into Segmentation fault.Next thing you wrote to KoVadim, the re-entry code is developer's case. He could have decided in some situations to return the code different from zero.Also, code different from zero can come back because of the development environment, for example, PyCharm was a mistake and code 135 returned at debage. And then we need to watch the IDE documentation and/or the IDE.The return code from QT shall be determined by two methods if the annex gives rise to a default, then 0, or the exit method(s) will be triggered, the return code will therefore be the one that is assigned to the function.Here's a simple example, just close-- it's okay, press the button and there's a return code 5. Code 5 is just because I decided.from PyQt5 import Qt class Window(Qt.QWidget): def __init__(self): super().__init__() layout = Qt.QVBoxLayout(self) self.btn = Qt.QPushButton() layout.addWidget(self.btn) self.btn.clicked.connect(self.on_button) def on_button(self): Qt.QApplication.instance().exit(5) if name == 'main': app = Qt.QApplication([]) w = Window() w.show() result = app.exec() print(result) if result == 0: print("It's OK!") else: print("Something wrong! Button was pressed!")

As far as I know, no. Create a separate view for this.

> name = ExelInfo() Can we do that?'Cause QMessageBox works like that!You can't do that. But you can. QMessageBox Make a statistical method and from it generate dialogue and dialogue, for example:class ExelInfo(QDialog, exel_info_class): # ... @staticmethod def get_name(): info = ExelInfo() info.exec() if info.ok: return info.name.text() And use:name = ExelInfo.get_name()

To spin a picture taken with help. QPixmapYou can. QTransform().rotate() Use. Code based https://stackoverflow.com/a/31901111/4279 :#!/usr/bin/python3 """Usage: rotate-image <image>""" from PyQt5.Qt import QImage, QLabel, QPixmap, QTransform, QWidget, Qt class ImageRotor(QWidget): def init(self, image_path, parent=None): super().init(parent) self.label = QLabel(self) self.image = QImage(image_path) # keep original image for rotation self.angle = 0 self.label.setAlignment(Qt.AlignCenter) # NOTE: keep image on screen pm = QPixmap(self.image) self.resize(pm.width(), pm.height()) # fit window to image self.label.setPixmap(pm) self.setWindowTitle('PyQt5 Image Rotor') def keyPressEvent(self, event): # on any key self.angle += 45 if event.key() == Qt.Key_Down else -45 t = QTransform().rotate(self.angle) self.label.setPixmap(QPixmap(self.image).transformed(t)) return super().keyPressEvent(event) if name == 'main': import sys from PyQt5.Qt import QApplication if len(sys.argv) &lt; 2: # wrong arguments sys.exit(__doc__) # print usage app = QApplication(sys.argv) w = ImageRotor(sys.argv[1]) # center on screen w.move(app.desktop().screen().rect().center() - w.rect().center()) w.show() sys.exit(app.exec_()) When pressed on any keyboard, the image on the command line reverts to 45 degrees. If you press the keyboard. Yes ( &quot; down &quot; ) and the clockwise is rotating.The initial size of the window shall be placed under the imagecentre-down shall be used so that the image does not runThe original image is retained so that the reversal would not distort the picture.

A little tip first: make a full-blown mistake (the best part of a full-time job) or you've got to guess, and telepaths and guessers usually leave.Now the code. First of all, check your backs. I certainly hope you've dug up the code, but still. Second, if connecttocli and connecttosrv It's class methods, they're supposed to be transferring. self as a parameter (all class methods need to pass the parameter selfclass MserverGUI(QtWidgets.QMainWindow, mservergui.Ui_TechControlMSRV): def __init__(self, parent=None): super(MserverGUI, self).__init__(parent) QtWidgets.QMainWindow.setFixedSize(self,500,500) self.setupUi(self) self.consettings.hide() self.conbtn.clicked.connect(self.connecttocli) self.msrvcon.clicked.connect(self.connecttosrv) def connecttocli(self, a, b): a = None b = None return def connecttosrv(self, a, b): a = None b = None ip = self.masterSrv.text() #Вот тут ошибка try: sock.connect((ip, 14061)) except Exception: QtWidgets.QDialog.QErrorMessage(self, "Невозможно подключиться к указанному IP.") return return

Good day. Recently faced the same problem. Judging from what I understood, PyCharm couldn't properly dissolve the PyQt5 library and it was wrong. skeletonsand they appear to have had this problem since 2012, with different versions. In different forums, it is written that the issue is PyQt5.3 et seq., that is, a ready skeleton with a more early version (e.g. PyQt5.2) and can be copied to itself (on the way forward) .PyCharm2016.1/system/python_stubs/-*********/)Here are the ways I have found to solve this problem:Can be listed instead of a line from PyQt5 import QtWidgets line from PyQt5.uic.Compiler.qtproxies import QtWidgets♪ Then all methods inside the class are defined. But it's a pretty local solution.A more global solution. Establish manually skeleton PyQt libraries. There are several teams to do so (in my case 4). Examples for Linux environment, Windows are similar:==> python3 generator3.py -x -d ~/.PyCharm2016.1/system/python_stubs/-1247971765/ PyQt5 <br> ==> python3 generator3.py -x -d ~/.PyCharm2016.1/system/python_stubs/-1247971765/ PyQt5.QtWidgets <br> ==> python3 generator3.py -x -d ~/.PyCharm2016.1/system/python_stubs/-1247971765/ PyQt5.QtCore <br> ==> python3 generator3.py -x -d ~/.PyCharm2016.1/system/python_stubs/-1247971765/ PyQt5.QtGui <br><br> I want to point out that after my journey, PyQt5, PyQt5. QtWidgets, etc., are written through a gap.P.S. Fire generator3.py is on the way. PyCharm2016.1/helpers/generator3.pyExample for Windows:==> python "C:\Program Files\JetBrains\PyCharm 5.0.1\helpers\generator3.py" -x -d "C:\Users\user\.PyCharm50\system\python_stubs\324234324" PyQt5

You know, that's what you need in the method. openMenu Call the method. self.listSource.itemAt(position) and check None♪ If None If you don't do anything, I'll show you the menu.

That's the decision I'll write as I can.self.material = material.Material() # Создаем экземпляр класса окна которое будет внутри MDI self.sub_material = QMdiSubWindow() # Создаем пустое под окно MDI self.sub_material.setWidget(self.material) # Заполняем пустое окно нашим классом self.mdi.addSubWindow(self.sub_material) # Добавляем окно к самой MDI области self.sub_material.resize(self.material.size()) # Редактируем размер MDI под окна, взяв размеры из созданного в дизайнере класса self.sub_material.show() # Отображаем под-окно

We need to create an object:dialog1 = Dialog() You're just a type. Dialog Transferred self.mdiArea.addSubWindow

After pip3, put it in a python with a 3,4 version.
