Re: [PyQt] Synchronized scrolling between two tables
Thanks Wolfgang and Scott. Wolfgang, Initially I had wanted to use one table. But I couldn't figure out how to disable certain columns. My data goes in the first three columns, then the calculation results are populated in the next 5 columns. I don't want the user to be able to edit/select the calculated 5 columns. That is why I implemented two adjacent tables. If their is a way to disable certain columns in a table from being selected, I would appreciate if you can guide me to it. Thanks again!

Have a look at classes ScoreViewLeft, ScoreViewRight and ScoreTable in kajongg http://websvn.kde.org/trunk/KDE/kdegames/kajongg/src/scoring.py?view=markup but I do not see the need for two tables in your case, I would try to use one single QTableView. Initialize the calculated fields to empty and after having calculated them, refresh the view. you do not even need a calculate button. If your calculation really needs some time, you can put the calculation into a separate thread and automatically update the view when a field has been calculcated. -- Wolfgang ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt -- View this message in context: http://old.nabble.com/Synchronized-scrolling-between-two-tables-tp32761709p32765646.html Sent from the PyQt mailing list archive at Nabble.com. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

In the link I gave you there is a file rulesetselector.py which defines a tree view where some items can be edited in different ways (combobox, text, numbers, checkboxes). Your table view should be easier to implement. def flags(self, index): # pylint: disable=R0201 tell the view what it can do with this item if not index.isValid(): return Qt.ItemIsEnabled column = index.column() item = index.internalPointer() content = item.rawContent checkable = False if isinstance(content, Ruleset) and column in (0, 3): mayEdit = True elif isinstance(content, Rule): mayEdit = column in [0, 1, 2, 3] checkable = column == 1 and content.parType is bool else: mayEdit = False mayEdit = mayEdit and not isinstance(item.ruleset(), PredefinedRuleset) result = Qt.ItemIsEnabled | Qt.ItemIsSelectable if mayEdit: result |= Qt.ItemIsEditable if checkable: result |= Qt.ItemIsUserCheckable return result ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] setUniformValueArray missing
Greetings, I'm currently developing an OpenGL PyQt app. I'm in the need of this function http://doc.qt.nokia.com/latest/qglshaderprogram.html#setUniformValueArray-20 (setUniformValueArray) but I can't seem to find it anywhere in the most recent PyQt documentation. Is there any chance that this function will be added in the near future?

Re: [PyQt] Synchronized scrolling between two tables
Thanks Guys, I found the solution to my problem. By linking to the tables scroll bar via (QScrollBar) I now have access to the bar. Then using the signals emitted by the slider via (QAbstractSlider) I can get the current location of the bar and then sync the other table with it. Here is a short example (right table syncs with left, I just need to add another signal for left table to synch with right). # from PyQt4.QtCore import * from PyQt4.QtGui import * import sys import time class MyWindow(QWidget): def __init__(self, *args): QWidget.__init__(self, *args) self.tableWidget1 = QTableWidget() self.tableWidget2 = QTableWidget() numRows = 40 numCols = 2 self.tableWidget1.setRowCount(numRows) self.tableWidget1.setColumnCount(numCols) self.tableWidget2.setRowCount(numRows) self.tableWidget2.setColumnCount(numCols) layout = QHBoxLayout(self) layout.addWidget(self.tableWidget1) layout.addWidget(self.tableWidget2) self.setLayout(layout) self.sliderBar1 = self.tableWidget1.verticalScrollBar() self.sliderBar2 = self.tableWidget2.verticalScrollBar() QObject.connect(self.sliderBar1, SIGNAL(actionTriggered(int)), self.SyncScroll) def SyncScroll(self): sliderValue = self.sliderBar1.value() self.sliderBar2.setValue(sliderValue) def main(): app = QApplication(sys.argv) w = MyWindow() w.show() sys.exit(app.exec_()) if __name__ == __main__: main() # Nader Abedrabbo wrote: Greetings, I have a program where two tables are shows next to each other.

[PyQt] PyQt and DBus in Python 3
Ubuntu is looking at moving to Python 3. Currently PyQt depends on python-dbus for its DBus support, but we believe that there are no plans to port python-dbus to Python 3 (because the gtk 3 bindings now have their own DBus support). Are there any plans for adding PyQt bindings to the QtDBus module? Or another expected way to get DBus support in PyQt with Python 3? Thanks Jonathan Riddell ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Thanks for your quick response :) Nothing immediate, our hope of switching to Python 3 for our April 2012 release won't happen because of a number of issues. However we'd like to start porting Ubuntu's various GUI applications to Python 3 and an incomplete PyQt for Python 3 will prevent us from starting on that.
