  1. POPyQt: getting widgets to resize automatically in a QDialog
    text
    copied!<p>I'm having difficulty getting widgets in a QDialog resized automatically when the dialog itself is resized.</p> <p>In the following program, the textarea resizes automatically if you resize the main window. However, the textarea within the dialog stays the same size when the dialog is resized.</p> <p>Is there any way of making the textarea in the dialog resize automatically? I've tried using <code>setSizePolicy(QSizePolicy.Ignored, QSizePolicy.Ignored)</code> on the dialog itself and the two widgets within, but that seems to have no effect.</p> <p>I'm using Qt version 3.3.7 and PyQt version 3.5.5-29 on openSuSE 10.2, if that's relevant.</p> <pre><code>import sys from qt import * # The numbers 1 to 1000 as a string. NUMBERS = ("%d " * 1000) % (tuple(range(1,1001))) # Add a textarea containing the numbers 1 to 1000 to the given # QWidget. def addTextArea(parent, size): textbox = QTextEdit(parent) textbox.setReadOnly(True) textbox.setMinimumSize(QSize(size, size*0.75)) textbox.setText(NUMBERS) class TestDialog(QDialog): def __init__(self,parent=None): QDialog.__init__(self,parent) self.setCaption("Dialog") everything = QVBox(self) addTextArea(everything, 400) everything.resize(everything.sizeHint()) class TestMainWindow(QMainWindow): def __init__(self,parent=None): QMainWindow.__init__(self,parent) self.setCaption("Main Window") everything = QVBox(self) addTextArea(everything, 800) button = QPushButton("Open dialog", everything) self.connect(button, SIGNAL('clicked()'), self.openDialog) self.setCentralWidget(everything) self.resize(self.sizeHint()) self.dialog = TestDialog(self) def openDialog(self): self.dialog.show() if __name__ == '__main__': app = QApplication(sys.argv) mainwin = TestMainWindow(None) app.setMainWidget(mainwin) mainwin.show() app.exec_loop() </code></pre>
