Hi Pierre,

How can I contact you regarding contributing to the shell's code?

Eli

  
I'm very sorry, I completely missed all replies made to my post, I was 
too busy working on PyQtShell on my free time :)


Eli, I see that you've found out how to contact me.
The best way to contribute to the code is to use Mercurial, either by 
creating a clone of the read-only repository at 
http://source.pythonxy.com/PyQtShell/, or by downloading the source 
archive (on Google Code: http://code.google.com/p/pyqtshell/).
After that, you may update your local repository by doing a "Pull" from 
time to time. And if you want to contribute, send me your "diff" files 
by e-mail, I'll integrate them with great pleasure.


Frederic, I know about pyqonsole (and about Logilab too: we are working 
together on a project at my research center, CEA/DAM) and PyQtShell is - 
until now at least - intended to be only emulating the Python 
interpreter without emulating any kind of terminal (which is a 
limitation but it has the advantage to simplify greatly the code).


Cheers,
Pierre

QTextEdit doesn't expose any actions of its own, so you will have to create
your own. Take a look at the Application example supplied with PyQt (in the
examples/mainwindows/application directory) for code to do this.

Sadly, default icons for actions are apparently not a feature common to all
platforms, so you'll need to find a source of those. Perhaps someone reading
can suggest a good source of suitably-licensed icons.

Re: [PyQt] PyQt, QWebView, SVG Rendering Problem

This is a common problem with most Web browsers because SVG support is not
as widespread as it would ideally be. Does the page appear as it should do
in other browsers?

I don't think that Qt's support for SVG will make any difference here
because WebKit is doing the rendering. I don't know what features WebKit
has for embedding SVG 1.1 drawings into pages, but it seems to be able to
display them (Qt 4.4.3, PyQt 4.4.4, Linux) if you pass the URL to the
SVG itself to QWebView's load() method.

In fact, it seems that they can also be embedded into the page. The following
simplified XHTML markup worked for me:

http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";
  xmlns:svg="http://www.w3.org/2000/svg";
  xmlns:xlink="http://www.w3.org/1999/xlink"; lang="en">

  
  SVG Test


I am Object showing SVG

Your Browser does not support SVG




Initially, I was convinced it wasn't working because I couldn't see the
picture immediately below the "?" images, but scrolling down to the bottom
of the page revealed it.

[PyQt] QGraphicsScene/Item/View coordinates

2009-01-23 Thread Frédéric 
Hi,

I would like to use QGraphicsXxx objects to create a widget which displays 
all pictures the motorized panohead will shoot, like this (done in PyGTK):

http://trac.gbiloba.org/papywizard/attachment/wiki/ScreenShots/shootDialog_mosaic_pc.png

I'm sure there is a simple way to avoid all computations I had to do with 
PyGTK, but I'm not yet familiar with this framework.

1) Is it possible to define my scene so its coordinates fit my shooting 
field of view? For example, if the user selects horizontal fov as [-90°, 
90°], and vertical fov as [-45°, 45°], should I instanciate the 
QGraphicsScene like this:

QGraphicsScene(-90, -45, 180, 90)

so if I add an item (say a rectangle) created by:

QGraphicsRectItem(-10, 10, 20, 20)

it will be centered in the scene?

2) I would like the previous scene always entirely visible in its view, 
whatever this view size is. How can I do that? Is it the purpose of the 
fitInView() method?

Thanks,

--

[PyQt] QTextEdit: Is there a default text edit display?

2009-01-23 Thread Marc Nations 
Hi,

I need to use rich text in an application which appears to be utilized using
QTextEdit. The edit options need to be available in the app. I assumed there
was an option to pop them up in the widget or in the toolbar somewhere, like
it does in QtDesigner. However I can't find anything to do that. I can build
my own actions, of course, but would rather not if I don't need to. Is there
a way to make the edit options available with default buttons?

Thanks,
Marc

It didn't seem to be possible the last time I tried to do this. I believe
that PyQt's meta-object support could be extended to allow custom enums
to be created in Python, but I don't know how much work it would be.

Sry for making the noise. At this moment - after hours of searching I found that
a member variable was hiding the method ...

[PyQt] Is it possible to use custom enums for custom widgets?

2009-01-23 Thread Umit Oztosun 
Hello,

I am using custom widgets and plugins. I can define custom properties
using pyqtProperty() using standart Qt types like int, bool, QColor
etc. I wonder if it is possible to use custom types, i.e. when the
widget is used in Qt Designer, I want a combobox to be displayed in
the Property Editor for the custom property (just like, for example,
focusPolicy QWidget property).

Is there a way to do this?

Umit

[PyQt] PyQt, QWebView, SVG Rendering Problem

Can any one help me resolve this problem. I would really appreciate any help
or direction.

My System and File details as follows:

[PyQt] QAbstractTableModel.data() implemented but get still

2009-01-23 Thread Michael Hammer 
Hi folks!

I've really tried a lot of different things - and I found one often proposed
solution to keep the instance of the model alive. As I can't find any error,
perhaps some of you can help.

The MainWindow where the model and view are referenced:

class MainWindow(QtGui.QMainWindow):
def __init__(self,parent=None):
QtGui.QWidget.__init__(self,parent)



self.model = table.TableModel([])
self.table_view = table.TableView()
self.table_view.setModel(self.model)
self.ui.gridlayout.addWidget(self.table_view, 0, 0, 1, 1)

And here is the model - I've indeed implemented the data() method:

class TableModel(QtCore.QAbstractTableModel):
def __init__(self,header,parent=None):
QtCore.QAbstractTableModel.__init__(self,parent)
self.header = ['a','b','c']
self.data = [['y','test1'],['n','test2'],['y','test3']]

def columnCount(self,parent):
return len(self.header)

def rowCount(self,parent):
return len(self.data)

def headerData(self, col, orientation, role):
 if ( orientation == QtCore.Qt.Horizontal and 
 role == QtCore.Qt.DisplayRole ):
   return QtCore.QVariant(self.header[col])
return QtCore.QVariant()

def data(self, index, role):
if not index.isValid():
return QVariant()
elif role != Qt.DisplayRole:
return QVariant()
return QVariant(self.data[index.row()][index.column()])

and there is some view to it:

class TableView(QtGui.QTableView):
def __init__(self,parent=None):
QtGui.QTableView.__init__(self,parent)

but I still get the error:

NotImplementedError: QAbstractTableModel.data() is abstract and must be 
overridden

Thx for any hint, greets

Michael
