[PyQt] QComboBox inside the QTreeWidgetItem?
Hi,
This is my first post to the list, so hello everyone!
I recently started developing a small PyQT4 application with VTK 3D
visualization, and I encountered a few problems, first one is
described in this email.
I wanted to include a combo box inside my QTreeWidgetItem, but it does
no appear on the screen:
self.tree_item = QTreeWidgetItem(self.widget_layers, [QString
(structure_name), QString(str(sequence_length))])
combo = QComboBox()
combo.addItem(QString('1st item'), Qt.DisplayRole)
self.widget_layers.setItemWidget(self.tree_item, 4, combo)
print type(self.widget_layers), type(self.tree_item), type(combo)
print returns following values:
class 'PyQt4.QtGui.QtreeWidget' class
'PyQt4.GtGui.QTreeWidgetItem' class 'PyQt4.QtGui.QComboBox'
What am I doing wrong?
I found similar listing in the archive:
http://www.riverbankcomputing.com/pipermail/pyqt/2009-August/024067.html
but author seems to have no problem with the QPushButton, which does
not appear in my app, so I assume that there is some other problem
than defining combo box like above?
And once it's working, how can I connect to its activated SIGNAL?
More general question would be: how can I get a reference to the given
item in the QTreeWidgetItem? There is text() but it's now always the
case...
Thanks,
Piotr Byzia

[PyQt] SIGNAL from checkbox embedded in the QTreeWidgetItem?
Hi, There is this email: http://www.riverbankcomputing.com/pipermail/pyqt/2009-October/024801.html Unfortunately, author did not post a follow-up post on how he got it done. I want to grab a signal from a checkbox added to the QTreeWidgetItem by the method: setCheckState(0, Qt.Checked) Could anyone help?

[PyQt] How to read this mailing list?
Hi, I wonder how do you read this list? Separate emails is not the most convenient way as there are app. 350 messages per month. Daily Digest is messy when replying. Is there any online front-end where I can read messages, search the list, and answer to a given message?

[PyQt] problem with QAbstractItemModel
Hi,
the attached script implements a minimal tree model featuring rows deletion.
It works just fine with (Qt 4.4, PyQt 4.4.4). However, with (Qt 4.5.2, PyQt
4.5.4) and (Qt 4.5.2, PyQt 4.6.1) deleting the last row raises the following
error:
v...@rachael:/tmp$ python tmTester.py
[2] 6819
v...@rachael:/tmp$ Traceback (most recent call last):
File tmTester.py, line 189, in index
return self.createIndex(row, column, branch.childAtRow(row))
File tmTester.py, line 86, in childAtRow
return self.children[row]
IndexError: list index out of range
Is it a bug in the recent versions of PyQt? Or should I fix some problem in the
script?
I would really appreciate your help.

[PyQt] Drag and Drops on Mac OS X
Hey everyone, I seem to be having difficulty getting drag and drops
working on a tool I am porting over from Windows to OS X. The short and
skinny is that I want to be able to drag a file from a finder into a
model based list view and the file name show up in the list view. I get
the cursor icon to show that it will accept a drop but when I release
click nothing happens. On my custom dragEnterEvent, dragMoveEvent and
dropEvent methods I put simple print statements to signify in the
terminal that the method is being executed, but no dice.
I have a feeling that the approach to OSX must be slightly different
than Windows so here's an abridged version of what I am doing and maybe
someone can tell me what I might be doing wrong
This simple example works fine on windows xp using PyQt 4.4.3 for python
2.5.1 but I can't seem to get it to work for PyQt 4.6 for python 2.5.4
on OS X. Any Ideas?

Re: [PyQt] SIP default exception handler
On Tue, 03 Nov 2009 17:04:38 +0100, Sébastien Petitdemange sebastien.petitdema...@esrf.fr wrote: Hi, We have tested your snapshot code and it works as expected. In fact, we had a rather obscure problem where our exceptions were thrown in our library, but it was not seen by your specific catch route. After a lot of research, we saw that the Python (distutils) Makefile hides by default the library symbols, except the initModule function. It seems that this filtering also affect weak symbols with default values, and we believe that this avoided the try ... catch block to properly identify in run-time the good exception type id. The solution we found was to specify export_all=True in the Module Makefile. However, we have also seen a problem with dynamic parameter allocation. In the example below, the /Out/ std::string buffer parameter is created by sip. However, inside of our /Default/ exception handler or even the catch (...) handler, the object is not deleted. Do you have an idea of what could be happening? Should be fixed in tonight's snapshot. Phil ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
