Small terminal/console with vt100 emulation

Hello,
because pyqonsole only works with Qt3 and porting to Qt4 looks
complicated, I used the vt100 implementation of AjaxTerm and created a
PyQt4 widget for it.
Now I can embed a shell in my Linux applications. If anyone else is
interested in such a thing you will find the current version at
http://www.henning-schroeder.de/pyqterm.tgz

Regards
Henning

Can't insert Nulls Using QSqlQuery.execBatch

Greetings,

Using PyQt, I am having a problem inserting Nulls into a MySql table using the execBatch() method of QSqlQuery. From the documentation, a null QVariant (i.e. QVariant(QVariant.Double)) represents a Null when inserting.  When doing a regular query.exec_ it does actually insert Nulls, however when I do a query.execBatch(), zeros get inserted, not Nulls.

query.prepare(INSERT INTO `table` VALUES (?, ?))

var1=[1.0, QVariant(QVariant.Double)]
var2=[QVariant(QVariant.Double), 32.6]

query.addBindValue(QVariant(var1))
query.addBindValue(QVariant(var2))
query.execBatch()

With the above code, I would expect this to be inserted (Nulls should appear where QVariant objects in the lists are):

1.0  Null
Null 32.6

Instead what actually gets inserted is:

1.0 0
0   32.6

If I were to insert this line by line using just regular exec_ it would work, but I would rather use execBatch as I have many rows to insert at once (above is just an example). I have tried making every item in the lists a QVariant, whether Null or not, but I still get zeros, and I cannot pass in anything other than a QVariant to addBindValue (which I why I wrap the list in one when I call the method).

Any help would be greatly appreciated. Thank you.

Mark

Drag and Drop from one list into another with Model/View

Hi,

I have an application with 2 listviews (and corresponding models). The
first list view lists items. The second lists references to this items
(which can occure multiple times).

Now I want support drag and drop such that items from the first list
viewcan be dropped in the second.

So I try enable drag and drop by doing the following:
In the main window:

    self.ui.firstListView.setDragEnabled(True)
    self.ui.secondListView.setAcceptDrops(True)

now for the model of the first ListView:

    class FirstModel(QtCore.QAbstractListModel):
      ...
      def flags(self, index):
        return QtCore.QAbstractListModel.flags(self, index) |
QtCore.Qt.ItemIsDragEnabled
      def mimeTypes(self):
        return ["application/vnd.text.list"]

And for the second:

    class SecondModel(QtCore.QAbstractListModel):
      ...
      def mimeTypes(self):
        return ["application/vnd.text.list"]
      def dropMimeData(self, data, action, row, column, parent = None):
        print "dropMimeData"

Running the application I can drag items from the first listview, but I
can not drop it into the second (dropMimeData is never called).
What am I missing here?

Also:
As soon as I start dragging items, I get:
TypeError: invalid result type from FirstModel.rowCount()

rowCount returns an Int. Why do I get this message?

Thanks!

Re: QMenu.setTitle on OS X

Thanks for checking. Is it safe to assume this was a bug in Qt that
was fixed sometime between 4.5.3 and 4.7.x?

Probably. It certainly wasn't a PyQt change.
