Re: [PyQt] Synchronized scrolling between two tables
Note that actionTriggered(int) will return the value before the update. Instead, use valueChanged(int) to get the resulting value in this example.

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!

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
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.

Re: [PyQt] Synchronized scrolling between two tables
According to the documentation: QTableView.scrollTo (*self*, QModelIndexfile:///C:/Python26/Lib/site-packages/PyQt4/doc/html/qmodelindex.html *index*, QAbstractItemView.ScrollHintfile:///C:/Python26/Lib/site-packages/PyQt4/doc/html/qabstractitemview.html#ScrollHint-enum *hint* = QAbstractItemView.EnsureVisible) I assume you would have to create a QModelIndex based on the first tables' scrolled to record, and then feed it into the second table via a key press (or release) grab? If this is set up to fire for each scrolled record on the first table, it might get resource-intensive to 'synchronize' the scrolling, though.
