Hi,
I was just wondering if someone could advise me on the simplest way of
integrating a few simple charts (pie chart, time series chart, etc)
into my PyQT application.
Are there any chart widget libraries accessible through PyQT? Can they
be used through QT Designer?
Is it easier to just paint the
Hi,
I'm using a QDataWidgetMapper to map the fields in a database table to
the fields in a form.
The QSqlRelationalTableModel model associated to my QDataWidgetMapper
has a sort criteria on the basis of an integer field.
My problem is how to set the correct index of the QDataWidgetMapper
when a ne
Hi,
QSqlQuery's size method gives the number of rows retrieved with a
query. But is there some way to get the number of fields (columns) of
that query?
Many thanks.

Hi,
I'm using a QDataWidgetMapper to map the fields in a database table to
the fields in a form.
If a field in the form is left empty I would like a null value to be
inserted in the database field.
However, empty fields are given a 0 value for numeric fields and an
empty string value for text fiel

Hi,
I'm programming in PyQt using the Eric4 IDE and QtDesigner.
I've created a QLabel containing a png image that displays fine when
previewing the form in QtDesigner, but when I execute my python
program from Eric, the image is not visible.
Do you know what I'm doing wrong?
Many thanks.

Hi,
I've noticed that QSqlRelationalTableModel reports numeric null
fields as zero. I wonder if this is a bug.
What is the simplest way to change this behaviour to set NULL values
to blank instead of zero when they are displayed?
Many thanks.

the beforeInsert signal, or have I got that wrong?
Thanks again

the data is submitted to the database but I have a problem
