[PyQt] negative index setWidget not working as expected
Hallo, inserting widgets with a negative index does not work as expected. I was expecting -1 to add a widget to the end and -2 to insert it right before the last widget in the layout. Is my assumption wrong? Demo code: from PyQt4.QtGui import QLineEdit, QCheckBox, QPushButton, QDialog, QFormLayout, \ QVBoxLayout, QApplication class Gui(QDialog): def __init__(self): QDialog.__init__(self) editLayout = QFormLayout() editLayout.addRow(enter something:, QLineEdit()) editLayout.addRow(enter another something:, QLineEdit()) button = QPushButton(press me) layout = QVBoxLayout() layout.addLayout(editLayout) layout.addWidget(button) self.setLayout(layout) self.layout().insertWidget(-2, QCheckBox(check me!)) app = QApplication([]) g = Gui() g.show() app.exec_() cheers Sebastian ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

So, I generated a test UI file in Designer with all properties on the table widget, the vertical and horizontal titles and cells themselves (attached) And then I ran the compiler and looked at the code (attached) and found the following things missing: QTableWidget: 1. .font.Kerning not compiled. 2. .font.Antialiasing not compiled 3. .QTableView.sortingEnabled is placed in reTranslateUI - however this does not seem to be concerned with internationalisation and I feel should be in the main code (though I could easily be wrong here) 4. .QTableWidget.rowCount .columnCount - if these are specified explicitly in QT Designer then they appear twice in the .py file.

First of all, what are you trying to archive? In order to breathe life into these objects, you need to add some code, generated by yourself (brain and all..). Designers output is a suitable basement for this task (in terms of subclassing or calling into), but in no way it's meant to be exhaustive. If you question the output of pyuic4, the very next thing to do is comparing it with the output of uic. Since that is the reference implementation for pyuic4, any significant differences should be dealt with, and I guess, if nobody jumps up and provide patches, Phil will sometime (depending on his priorities and importance..). Whilst we are looking at this code, it would also be helpful if we were to leave a blank line between code for QTableWidget, Horizontal Headers, Vertical Headers and Cells. Since pyuic4 output is not meant for human consumption (apart from debugging purposes), a patch from you in this area is highly unlikely to be applied by Phil..

Phil ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt The Qt docs say: Returns the IPv6 address as a Q_IPV6ADDR structure. The structure consists of 16 unsigned characters. So in Python it should return a list (or tuple if it should be immutable) of 16 integers. Are you suggesting a list because that is the closest equivalent in Python? If so I would disagree. Or are you suggesting a list because of how you want to use the value? I should have thought a second longer. A 16 int tuple would be best (as you already implemented).
