Was it done so for performance reasons or was there something that couldn't easily be done in Python?

Especially since existing build systems will have to go though hoops to be compatible with older and newer pyrcc4. The older one doesn't like to be passed the -py2 option. > Is there a way that it could figure out >which version of Python it is running with and use that to determine >what kind of code to generate?

[PyQt] Drag and drop toolbar buttons?
Hello all, Does anyone know of a good way to implement drag-and-drop for toolbar buttons? I would like to be able to reorder the buttons, as well as remove and add them by dragging to the toolbar from a list of actions. I suppose this is a general qt question more than a pyqt one, but I thought I'd ask here in case there was a Python solution already out there.

[PyQt] Implementation of the editabletreemodel example
Hi,
Here is the PyQt implementation of the editabletreemodel itemviews example.
The code was written from the C++ implementation, with space only inside.
Feel free to make any necessary changes such as adjusting the header
(copied from simpletreemodel.py example) or removing ui_mainwindow.py
and editabletreemodel_rc.py generated files provided for convenience.
Feel also free to add that example in the next PyQt release.
Best regards,
Cyril
PS: if you really want the exactly the same behaviour than the C++
implementation, you can apply the provided patch. I think it is more
consistent to insert "[No data]" whatever the insertion case though.

[PyQt] Re: QComboBox: display an item different from the chosen one in the QListView
TP wrote:

> without success (for example, "currentText", "setItemText", etc.).
For those that are interested, or Qt beginners like me: by examining Qt C++
source code, I have finally found a solution: I have specialized paintEvent
in my QComboBox derived class. For example, if I want to print "toutou" in
my QComboBox, I modify the QStyleOptionComboBox in paintEvent:
def paintEvent( self, qpaintevent ):
painter = QStylePainter( self )
painter.setPen( self.palette().color( QPalette.Text ) )
# draw the combobox frame, focusrect and selected etc.
opt = QStyleOptionComboBox()
self.initStyleOption( opt )
opt.currentText = QString( "toutou" ) # HERE!!
painter.drawComplexControl( QStyle.CC_ComboBox, opt )
# draw the icon and text
painter.drawControl( QStyle.CE_ComboBoxLabel, opt)
I have just translated paintEvent from C++ to Python, and add the
line "opt.currentText = QString( "toutou" )" to modify the content of the
QComboBox once one item has been chosen by the user.
Thanks
Julien
