The code below will show all file dialogs:įrom PyQt5.QtWidgets import QApplication, QWidget, QInputDialog, QLineEdit, QFileDialog The method parameters let you specify the default directory, filetypes and the default filename. The methods used are QFileDialog.getOpenFileName(), QFileDialog.getOpenFileNames(), QFileDialog.getSaveFileName(). By calling the functions included in PyQt5 you get the default file dialog, you don’t have to recreate these dialogs from scratch. nnect(self.button, SIGNAL('clicked()'), self.PyQt5 supports (native) file dialogs: open file, open files and save file. Self.button = QtGui.QPushButton('Quit', self) nnect(self.other_window, SIGNAL('closed()'), self.main2Closed) nnect(self, SIGNAL('main2closed()'), self.clearMain2) nnect(self.button, SIGNAL('clicked()'), self.spawnMain2) Self.button = QtGui.QPushButton('Create other window', self)
The only problem is that it is (terminal output): PyQt-converter-2.0]$ python PyQt-converter.pywĪlso, in case it helps, I can minimally have one QMainWindow kick off instances of the other, with or without explicitly deleting the second: import sys I'm using Linux and this program works correctly.īut small problem your code: class CustomWindow(QMainWindow):ĭef _init_(self, factorsFile, parent = None): How can I kill the object? What's the Python function/method/whatever to destroy an object? The above simply closes the window but keeps the object alive. nnect(self.customWin, SIGNAL("closed()"), self.OnCustomWinClosed) Self.customWin= CustomWindow(self.factorsFile) How can I instantiate an object and then destroy it after closing the window? At the moment this is the only code which doesn't crash but it's still not what I'm looking for: class MainWindow(QMainWindow): Well, this and show()/close() still crashes it as they only close the window but they don't destroy the actual object. If you can supply a simple example of what you want to do it would help as you may want to use setModal or closeEvent. nnect(qApp, SIGNAL(lastWindowClosed()), qApp, SLOT(quit())) To destroy the object, assign something else to the variable. nnect(slider, qt.SIGNAL("valueChanged(int)"), lcd, qt.SLOT("display(int)")) Slider = qt.QSlider(qt.Qt.Horizontal, self, "slider") tFont(qt.QFont("Times", 18, qt.QFont.Bold)) Quit = qt.QPushButton("Quit", self, "quit") import sysĭef _init_(self, parent=None, name=None): Most of the tutorials for qt3 (if that is what you are using), use sys.exit(). What's the Python function/method/whatever to destroy an object?
