Re: [PyQt] embedding iconic pushButton in TableView and/or TreeView
>Just remember, that small self contained examples of such issues are the
>ultimate weapon to engage them...
>Pete
lol, totally,...I went back to Mark Summerfield's book again (and other
examples)...
I'm soo close...but still a step or two go...
Finally figured out how to use my delegate's "sizeHint" to adjust
the row height in a QTreeView..
def sizeHint(self, option, index):
fm = option.fontMetrics
if index.column() == 2: # LongName, but could be any column #
text = index.model().data(index)
document = QTextDocument()
document.setDefaultFont(option.font)
return QSize(document.idealWidth() + 5, 50)
return QStyledItemDelegate.sizeHint(self, option, index)
...the "50" being the height I needed for a 50x50 icon image in the
first column
So,...it finally occurred to me that when MarkS says a delegate
can have "total control"...then that must mean everything must
pass thru the "paint" function...which strikes me as more of a filter
than a function,..but anyways...
Right now, I have
def paint(self, painter, option, index):
if index.column() == 0: # Thumbnail
parent = self.parent()
iconFile = index.model().data(index, Qt.DisplayRole)
button = QPushButton("&Icon", parent)
icon = QIcon(iconFile)
pixmap = icon.pixmap(QSize(50, 50) )
button.setIcon(icon)
painter.save()
painter.drawPixmap(0, 0, 50, 50, pixmap )
painter.restore()
else:
QStyledItemDelegate.paint(self, painter, option, index)
So, even though there's a PushButton definition in there, I still can't
get it to display at startup. I have been able though to define an
Icon and Pixmap, (passing the image filename from data() )
but painter only wants (it appears) to draw a pixmap, and not a
pushbutton...so I'm kinda' stuck there at the moment...
But I do have these pixmaps showing at startup...so I'm think I'm
tantalizing close to a solution...
Now it might be,...that I may not absolutely need a pushbutton type..
I just need to enable the user that once they click on pixmap/button
that it would execute a function. Even that could be argued away
with,...by proving a RMB (rightmousebutton) pulldown menu in the
main view...Even so, I'd still like to understand and know how to do
the former,etc..
Anyways,...Any suggestions greatly appreciated...and Thanks again, Pete, for
your help and interest,
Cheers,
-James

Re: [PyQt] How does sip.setapi("QString", 2) work with translations?
Hello Brett,
with sip.setapi("QString",2) you gets always an unicode string back,
witch is a true python object. So there can't be any Qt methods any
more. This is why your second example fails.
You have two solutions. The one you mentioned or since Python 2.6 the
new unicode format method:
qApp.translate("test","Internationalize {0}").format(42)
or with named arguments:
qApp.translate("test","Internationalize {my_number}").format(my_number=42)
There are many other options for the format method described in the
Python documentation.

When I try:

I get

Is there a way to get this to work using Qt style formatting? Or do I need

Everywhere I return a String in the data() routine, this is displayed with a check box - even if I cast it to QVariant. If I call resizeColumnsToContents() on the view, all the columns are set to a very small size that shows only the check boxes. :( I am using Python 2.7, PyQt 4.7.4 and Windows 7 (64 bit). I don't believe that QAbstractTableModel can be quite that buggy. So what am I doing wrong? Anyone? Please?

You need a item delegate, then.

[PyQt] simplewidgetmapper.py, customsortfiltermodel.py, combowidgetmapper.py examples
Hi Phil, hi *, attached are a few missing itemview examples for the collection. While simplewidgetmapper.py and combowidgetmapper.py differ only in minor details, the customsortfiltermodel.py differs from the original in a major aspect: it actually works unlike the original ;-) - the filters are applied on startup (UI shows consistent values) - the date limiter contain sane values - the date filter works properly The last issue in MySortFilterProxyModel.dateInRange() results from a slight inconsistency in Qt: comparing QDate with QDateTime values doesn't work (at least not in a way, what would humans expect), hence the value has to be converted to a QDate before the comparison. Enjoy, Pete simplewidgetmapper.py Description: application/python customsortfiltermodel.py Description: application/python combowidgetmapper.py Description: application/python ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Confirmed. Your change from the attached diff does fix this issue.
Thanks a lot.
Attached is a streamlined version of the the coloreditorfactory script,
incorporating a few improvements from Baz' version and with the
copyright header intact.
Hans, I dimly remember your issues with model proxies and disappearing
internalPointers.. The attached patch might be worth a try.

While better error messages are greatly appreciated, I expect locating such problems will still going to be tough in a big library, because of the inherent ambiguity. Wouldn't unambiguous %End directives allow for much easier formal consistency verification (e.g. %EndIf, %EndTypeHeaderCode, %EndMethodCode, etc..). @all: How could class templates be supported in an easier way? As far as I understand it, one has to specify all different types one by one. How about a %TemplateTypes directive?
