I found a decision to use the same WebView, only to change Link Delegation Policy webview.page().setLinkDelegationPolicy(QWebPage.DelegateAllLinks) And put the processor on the signal: def linkClicked(url): webbrowser.open(str(url.toString())) self.webview.connect(self.webview.page(), SIGNAL("linkClicked (const QUrl&)"), linkClicked)

Something like that. getattr(self, 'out{0}'.format(i)).setText(u'Обшибка')where i is the mark number (1-out1, 2-out2, 3-out3)Corrected. After self, the point was wrong.I don't have any comments, I'll ask you what. self.out(s).setPixmap(icon)..is out here function challenged with s?

We need to add the click to the references and link the click signal to the loading of the clicked reference:... window = QtWebKit.QWebView() window.page().setLinkDelegationPolicy(QtWebKit.QWebPage.DelegateAllLinks) window.linkClicked.connect(window.load) ...

As a result of the discussion in the commentaries, it was suggested that dialogue should be initiated not through a negative dialogue, using the flag. https://doc.qt.io/qt-5/qfiledialog.html#Option-enum :QtGui.QFileDialog.getExistingDirectory(None, u"Выберите рабочую папку", options=QtGui.QFileDialog.DontUseNativeDialog)

Check if there's any windows on your windows. several versions of python♪ I had a problem like this, only with the pygame. You can check if there's two IDLE openings when you open a file. It's also possible that module not supported or something.♪

Reading. http://doc.qt.io/qt-4.8/qwidget.html#close : Closes this widget. Returns true if the widget was closed; otherwise returns false.As you can see, there is nothing to say about the release of the memory of the object. QWidget♪I can't tell you how exactly the memory manager works at the python, I'll get the code for c++:void foo() { QWidget w; w.show(); .... w.close(); } void bar() { QWidget* pw = new QWidget(); w->show(); .... w->close(); } Description:Function foo():creates a class object QWidget♪Shows the window,doing something else. ♪ ♪Close the window,object w destroyed when the comes out of sight, the memory is released.Function bar():creates a class object QWidget Dynamic memory♪Shows the window,doing something else. ♪ ♪Close the window,object *pw is not destroyed, and the memory is not released, as the software does not intentionally call the operator. delete♪

Here. https://stackoverflow.com/questions/2880316/hide-console-window-with-wxpython-and-cxfreeze There's an answer. But in my personal opinion, making exe-coups with a pieton is a catastrophe.

<code> class MyClass: def work(self): for r in range(100): if r == 2: self.msgBox('MyClass PAUSE') else: print(r) time.sleep(1) def msgBox(self, txt): s = self.global_.MainWindow.stop self.global_.MainWindow.SignalBox.emit(txt) while self.global_.MainWindow.stop == s: pass while self.global_.MainWindow.stop: pass class MainWindow(QtGui.QWidget): ... def __init__(self): ... self.stop = False def box(txt): self.stop = True getattr(QtGui.QMessageBox(), 'information')(self, txt, txt) self.stop = False self.msgBox = box ... </code> That's how it stops:

In your class. QWidgetYou can redesign the processors of different events.You're interested in processing the clavicle-- redesign the method.virtual void keyPressEvent(QKeyEvent* event) Test example:class TestWidget(QWidget): def __init__(self, parent = None): QWidget.__init__(self, parent) def keyPressEvent(self, event): print("pressed key " + str(event.key())) if name == "main": import sys app = QApplication(sys.argv) tst = TestWidget() tst.show() sys.exit(app.exec_()) The program prints a tight button code in the console.

Read the warnings to the console during your program.Signed:Object::connect: No such slot QTextEdit: EnterPressed()You tried to connect the signal to a elephant that doesn't exist.Yeah, and besides, class. QTextEditwhich you use doesn't have a signal. returnPressed()♪ This signal is in class. QLineEditFor example. http://doc.qt.io/qt-4.8/qtextedit.html#signals ♪Fixed your example using QLineEdit:class Test(QtCore.QObject): def __init__(self, parent = None): QtCore.QObject.__init__(self, parent) @QtCore.pyqtSlot() def EnterPressed(self): print("blabla") if name == "main": import sys app = QtGui.QApplication(sys.argv) ptxt1 = QtGui.QLineEdit() ptxt2 = QtGui.QLineEdit() ptxt3 = QtGui.QLineEdit() ptxt1.setText("1") ptxt2.setText("2") ptxt3.setText("3") tst = Test() QtCore.QObject.connect(ptxt1, QtCore.SIGNAL("returnPressed()"), tst, QtCore.SLOT("EnterPressed()")) spl1=QtGui.QSplitter(QtCore.Qt.Vertical) spl2=QtGui.QSplitter(QtCore.Qt.Horizontal,spl1) spl1.addWidget(ptxt1) spl2.addWidget(ptxt2) spl2.addWidget(ptxt3) spl1.resize(500, 500) spl1.show() spl2.show() sys.exit(app.exec_()) Now I'll explain the steps.class Test(QtCore.QObject): - identified his class inherited. from QObject♪ Someone has to accept the signal.The designer just called the base class designer. Described actions performed by the signal response: @QtCore.pyqtSlot() def EnterPressed(self): print("blabla") Note that any slot is Not static On a class basis, it is it necessary to refer the reference to the object for which the method will be called first (and in this example the only) argument.Functions main created the object tst - A copy of the class Test:tst = Test() Connected the signal from the target. QTextEdit with a layer of object tst:QtCore.QObject.connect(self.ptxt1, QtCore.SIGNAL("textChanged()"), tst, QtCore.SLOT("EnterPressed()")) That's what you wanted.

In the terminal, insert:apt-cache search pyqt sudo apt-get install python-qt4

Cause of this mistake It's pretty interesting. It's what you need to do with it. PySide established PyQt4♪Pyqode Supports 3 modules Qt: PyQt5♪ PyQt4 and PySideAnd in the same order, he's trying to import them until something is successful. When the editor was established pyqodeThe first one was found PyQt4the one who once put it and his wrapper over it. QPlainTextEdit (sighs)PyQt4.QtGui.QPlainTextEdit() Called out and, uh, proved to be incompatible with PySide, because of that mistake, it appeared.I guessed the reason for the error when I started the code and saw the mention. PyQt4:import inspect print(inspect.getmro(type(self.code_editor))) It was:(<class 'pyqode.core.api.code_edit.CodeEdit'>, <class 'PyQt4.QtGui.QPlainTextEdit'>, <class 'PyQt4.QtGui.QAbstractScrollArea'>, <class 'PyQt4.QtGui.QFrame'>, ... To be sure, deleted. PyQt4 And then started again, it works, there's no mistake.What do you want to do?There are several options:Use a virtual environmentDon't keep the zoo of the modules for operation QtReclassify the project PyQt5 - it's the first on the import list (but how long?)

The color of the background: white, when the mouse comes, it becomes red, and when compressed, it's green:button_close.setStyleSheet(""" QPushButton:hover { background-color: red } QPushButton:!hover { background-color: white } QPushButton:pressed { background-color: rgb(0, 255, 0); } """)

If we'd read books,I'd see that. And that's it. And there it is. But I still prefer to use a species design. uic.loadUi("file.ui",self)♪Books on Boudewijn Rempt - GUI Programming with Python QT Edition [2001]. And A. Prophet - PyQt4. Establishment of final applications for Python 3 (I write python 2.7)

I think it's more appropriate for the Russian version, and as the Cotic said, it's enough to study Qt, for example. http://www.debugni.ru/index.php/qt45.html ♪

self.ui.textEdit.append(i)

We add a button to a pressurization panel that will be in an accidental place with an accidental flower of 20x20:app = QApplication(sys.argv) window = QMainWindow() label = QLabel() pixmap = QPixmap(label.size()) pixmap.fill(Qt.transparent) label.setPixmap(pixmap) window.setCentralWidget(label) window.setWindowTitle("Blur Effect Example") def draw_random(): painter = QPainter(label.pixmap()) # or: # painter = QPainter(pixmap) painter.setBrush(QColor(randint(0, 0xFF), randint(0, 0xFF), randint(0, 0xFF))) x, y = randint(0, pixmap.width()), randint(0, pixmap.height()) painter.drawRect(x, y, 20, 20) label.update() # or: # label.setPixmap(pixmap) general_tool_bar = window.addToolBar('General') action = general_tool_bar.addAction('Draw Rand Rect') action.triggered.connect(draw_random) window.show() sys.exit(app.exec_()) Skinshot:

It was simple. Change the code to this:if __name__ == "__main__": app = QtGui.QApplication(sys.argv) locale = QtCore.QLocale.system().name() if os.path.exists(os.path.join(str(QtCore.QDir.currentPath()), "language", "user_" + str(locale) + ".qm")): default_translator = QtCore.QTranslator(app) user_translator = QtCore.QTranslator(app) default_translator.load("language/default_" + locale) user_translator.load("language/user_" + locale) app.installTranslator(default_translator) app.installTranslator(user_translator) MainWindow = Ui_MainFormWindow() MainWindow.show() sys.exit(app.exec_()) And it all works properly)

In Python's script scripts, there's a violin uic (or pyuic) that converts...ui files into piton code.
