[PyQt] QTableView cell deselected after soting
Hello, I have found a strange behavior with a combo of QTableView, QSortFilterProxyView and disabled items. If you select a row in the table from the example below then sort by a column, the cell in the last column will be deselected after sorting. This happens only for cells with ItemIsSelectable as it's only item flag. Is there something I can do about this? Example: from PyQt4.QtCore import * from PyQt4.QtGui import * import sys my_array = [['00', '01', '02'], ['10', '11', '12'], ['20', '21', '22']] def main(): app = QApplication(sys.argv) w = MyWindow() w.show() sys.exit(app.exec_()) class MyWindow(QWidget): def __init__(self, *args): QWidget.__init__(self, *args) sorttablemodel = QSortFilterProxyModel(self) tablemodel = MyTableModel(my_array, self) sorttablemodel.setSourceModel(tablemodel) tableview = QTableView() tableview.setModel(sorttablemodel) tableview.setSelectionBehavior(QAbstractItemView.SelectRows) tableview.setSortingEnabled(True) layout = QVBoxLayout(self) layout.addWidget(tableview) self.setLayout(layout) class MyTableModel(QAbstractTableModel): def __init__(self, datain, parent=None, *args): QAbstractTableModel.__init__(self, parent, *args) self.arraydata = datain def rowCount(self, parent): return len(self.arraydata) def columnCount(self, parent): return len(self.arraydata[0]) def data(self, index, role): if not index.isValid(): return QVariant() elif role != Qt.DisplayRole: return QVariant() return QVariant(self.arraydata[index.row()][index.column()]) def flags(self, index): if index.column() == 2: return Qt.ItemIsSelectable return QAbstractTableModel.flags(self, index) if __name__ == "__main__": main() Cheers Sebastian ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] pyqtMethodProxy
Hello,
I was trying to connect the dataChanged signal of a QTableView instance
the "new style way" via its string name and __getattr__ like so:
treeview.__getattr__("dataChanged").connect(someSlot)
Instead of getting a bound signal (like I do with a ComboBox for
example), I am getting a pyqtMethodProxy, which does not have a connect
attribute. I can't find anything on the internet about this. Is there a
way to get the actual signal?
Cheers
Sebastian

[PyQt] pyuic resources import
Hello, my folder structure for an application I want to restructure is like this: src lib ui __init__.py MainWindow __init__.py MainWindow.ui MainWindow.py ui_MainWindow.py resources.qrc resources_rc.py main.py The MainWindow.ui uses icons from the resources.qrc (which I would also like to use for all other dialogs as well) and this works perfectly. pyuic translates the .ui file to ui_MainWindow.py and adds an "import resources_rc" This is where it stops working because in the MainWindow folder is no resources_rc file and thus the import fails. Ways to avoid this, which I thought about: * tell pyuic not to import resources_rc and import it manually in main.py * split the resources.qrc for icons only used in MainWindow.ui and put icons used in other dialogs in another qrc -> only what about icons used in MainWindow and another dialog and thus defined two qrcs. does the system use double the memory? * make pyuic aware of absolute imports like import lib.ui.resources_rc What is the recommended way of doing this?

[PyQt] negative index "setWidget" not working as expected
Hallo,
inserting widgets with a negative index does not work as expected. I was

the last widget in the layout. Is my assumption wrong?

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_()

Re: [PyQt] pyuic4 vs uic.loadUI
Hmm interesting topic, I recently had to switch back from ui files to py files because I couldnt get py2exe to package the ui files correctly (Any help appreciated though) Secondly using ui files I loose the comfort of auto-completion with pydev and Eclipse, because pydev wouldnt know how to deal with the ui xml data.

Does anyone have the pro's and con's of each of these methods? What is the recommended PyQT way of doing this? Thanks for starting the discussion, I've often wondered myself. I have no opinion one way or another, but since most seem to favour loadUI, I'll play the devil's advocate for pyuic4 :-) I can think of several reasons to prefer compiled ui files : 1) if you're using eric4 as an IDE, it does everything for you, so why not ? 2) on a reasonably recent PC, and for common UIs, the additional launch time, CPU& memory usage due to loadUI are probably not even measurable, compared to the Python, Qt and PyQt startup load. For extremely complex and widget-heavy UIs this might be less evident : parsing XML is not the most efficient thing in the world after all. And if we're running on mobile platforms with more limited power/CPU/RAM and slow Flash I/O, like Nokia's Symbian or Maemo smartphones, it could become quite perceptible. 3) during the early design phases, it's sometimes handy to be able to manually modify a generated Python UI file, just to check out the effect of some minor change, without having to do it in Designer (especially if it involves sizers :-) 4) if for some reason you wish or need to distribute only binaries, as sometimes happens, you can exclude the .ui source files and ship only the UI .pyc/pyo files.

Have you had a look at the capabilities example. Also please have a look

QMovie is an ancient class that basically plays animated GIF files and

PyQt doesn't appear to have any Phonon examples written in Python and, from

Re: [PyQt] QSystemTrayIcon not working with py2exe
Hello Nick,
my setup.py is autogenerated by GUI2exe. Find the contents below. As you
can see, I included the icon as data and icon file (even if I did not have
to when I was using ressources). both ways work when not compiled with
py2exe. I also tried several combinations with optimize, compressed and
bundle. also the QtCore and QtGui pyds and dlls get copied correctly... I
searched the web and the py2exe homepage, but it seems they do not have a
mailing list.
I'd appreciate all suggestions.
Sebastian

You might have forgotten to add the icon itself as a resource to
setup.py?

Re: [PyQt] QStandardItemModel best practice

[PyQt] properly exiting application while still in init
Hello, In the __init__ method of a standard QDialog I check for some requirements to be fulfilled before the gui is shown (I communicate with a server over a QTcpSocket for that matter) If the conditions fail I want to exit the Application. How would I properly do that? Currently I tried: socket.close() #first close the socket self.close() #close the window, does not do anything in the init because the window is not actually shown yet sys.exit() works but gives me an error (QWaitCondition: Destroyed while threads are still waiting) What could I try next?

Run the python script, expand one LevelOne item and select a LevelTwo item and in the menu choose add/edit levelthree. If you do this you should see an error or the interpreter will crash (try adding more items und expand them!). As said this error can be prevented by adding strong references for all items in the tree (which is something the createIndex obviously does not). Uncomment line 210 and 211 to see that adding all items to a list helps. The root item is owned by the model, so this should work, right?! The root item is owned by the model, but does the root item own all of its children, grandchildren etc.? I can see that it owns its children because you explicitly call its appendChild() method, but I'm not clear where the children's equivalent methods are called. Have you tried printing out the tree of items starting with the root item at various point to make sure the tree contains what you think it should? QAbstractItemModel won't maintain your model for you. As the documentation says, it "provides the abstract interface for item model classes" - the key word being "interface". It is not the container of the model data - that's the responsibility of a sub-class.

[PyQt] connect every widget to one slot
Hello, i created a dialog with some widgets. Now I'd like to connect every widget to a slot, so when the user changes values (for lets say a spinbox) a "dirty" flag for the dialog is set. Is there a way to accomplish this without connecting every widget explicitly? regards Sebastian -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] QAbstractItemModel causes segfault
Hello, I am using a QTreeView to display data coming from a sqlalchemy query. All is fine for displaying, but when I add rows, which also adds records to the database the "internal pointers", the QAbstractItemModel so heavily depends on, suddenly point to nowhere, because they don't keep strong references (crashing the interpreter). I am using the reference implementation of the editable tree example, with the small adjustment that instead of TreeItem my sqlalchemy class is used. So, at first it seemed like the error was produced by sqlalchemy, but with the help of the people on the other list I could verify, that its a problem of PyQt. To quote Conor from the sqlalchemy list: I believe the real problem is that these "internal pointers" are not doing proper incref/decref on the python objects they point to, so your python objects are getting garbage collected prematurely. The expire-on-commit readily exposes this issue, but disabling it will not really fix the underlying problem. A newer version of pyQT may do the incref/decref for you. If not, your QAbstractItemModel-derived object should keep strong references to everything that was pointed to by an "internal pointer" in a private list or set. This should prevent them from being garbage collected. I followed conors suggestion with the string reference list and it worked. The objects are not garbage collected, the tree builds and extends properly. Is there any pyqt developer, who can share his thoughts on this and maybe help. I don't want to scream: BUG! but to Michael Bayer, the creator of sqlalchemy this is one: if QT is maintaining a "reference" to something using its "memory address", but is not actually recording a strong reference to the object within the python interpreter, that sure sounds like a bug to me. It would imply that to use that library, every object you generate in Python must have a strong reference maintained, or QT now references invalid ids.
