Re: [PyQt] Limit the height of a Layout
It's generated code - it's not supposed to be pretty. All you do is import the gui code from your dialog class which is in a separate file. It keeps things clean and simple, and you won't have to start looking around APIs for stuff that QtDesigner does for you.

[PyQt] SIP and Q_PROPERTY
Hi, I've been handed a Qt widget class (C++) that has several Q_PROPERTYs.

The Q_PROPERTYs' getters setters are members of the class anyways, so wrapping those ought to provide the necessary functionality. You can't/don't need to. The fundamental problem is that in C++ property names and method names are in different namespaces and so they can (and sometimes do) clash. In Python they would be implemented in the same namespace (i.e. the class's dictionary) hence the problem. As a convenience you can use the QObject.pyqtConfigure() method to set any number of properties at once using keyword arguments. You can also set them when creating a new instance, again using keyword arguments. Phil ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Re: [PyQt] QAbstractItemModel's dataChanged signal not working?

The periods table is filtered by customer (whose ID is a foreign key) and shown through a QTableView. There's an Add button which basically inserts a new row in the Periods table and sets the view to edit mode, so the period data can be entered: def addRecord(self): row = self.model.rowCount() customerid = self._getRecordID(self.customerComboBox, self.customersModel, CUSTOMER_ID) self.enableControls(False) self.model.insertRow(row) index = self.model.index(row, CUSTOMER_ID) self.model.setData(index, QVariant(customerid)) index = self.model.index(row, PERIOD_YEAR) self.periodsTableView.setCurrentIndex(index) self.periodsTableView.edit(index) I noticed that, while the view is in edit mode (with the asterisk '*' appearing in the leftmost field), if the user clicks on the add button again, an empty row appears in the view and the asterisk appears in the next row, with this message on the console: edit: index was invalid edit: editing failed The same problem happens in the assetmanager.pyw example from the (great!) book Rapid GUI Programming with Python and QT, which is my main guide. That way, in my limited experience with PyQT, I tried to work around the undesirable behavior creating the method enableControls for the dialog, which is called in the addRecord method so it makes it impossible for the user to click on add again while the view is in edit mode. The idea then was to re-enable the controls when the data was finally committed by the view. That's when the main problem comes up. I tried to use the model's dataChanged signal for calling my enableControls method, but it looks like it never gets emitted, although the record does get written to the database table. Does anybody can confirm that or help me avoiding the problem at all? I used the following signature for the signal, exactly the same shown on QAbstractItemModel's documentation: self.connect(self.model, SIGNAL(dataChanged(const QModelIndex,const QModelIndex)), self.enableControls) That line is declared in my dialog's __init__, along with all the other (working) signals. self.model referes to the QSqlRelationalTableModel. Thanks for any help! Hi Claudio, I must admit that I've grown very frustrated with Qt's database support, particularly with SQLite. I've found that the book's database examples (which all use SQLite since that is supplied with Qt) exhibit varying differences in behavior depending on the Qt version. Regarding your specific problem, I can't see anything obviously wrong with your connection. Personally, I would have written it as self.connect(self.model, SIGNAL(dataChanged(QModelIndex,QModelIndex)), self.enableControls) but that should make no difference. Is your model a QSqlRelationalTableModel or a subclass? If it is a subclass and you have reimplemented setData() then you must emit the dataChanged() signal in your reimplemented setData() method. But if you're using QSqlRelationalTableModel directly then it isn't obvious to me what you're doing wrong. However, dataChanged() might be the wrong signal for reenabling the Add button since it is emitted for every change to every field, whereas I'd have thought you wanted to enable the Add button only when the record was inserted? So maybe you could try connecting to the QAbstractItemModel::rowsInserted() signal? I had a quick go at changing assetmanager.pyw to do this but without success (using PyQt 4.6 and Qt 4.5.2); maybe things have improved with Qt 4.6. -- Mark Summerfield, Qtrac Ltd, www.qtrac.eu C++, Python, Qt, PyQt - training and consultancy C++ GUI Programming with Qt 4 - ISBN 0132354160 Hello Mark, Thanks for your help, and specially for the great book you've written. It's been a really helpful source, very nice to read. It has saved me from quite a lot of endless trial and error loops! Back to the signals, I initially thought rowsInserted would be emitted as soon as the view entered editing mode, and since I needed something to reenable the controls - I had disabled them as soon in the beggining of addRecord - the idea was to use dataChanged because, since the model edit strategy was set to QSqlTableModel.OnRowChange, I thought it would be emitted only when the whole row was commited to the model. Anyway, your suggestion worked fine. Now I disable the buttons in the end of addRecord method, after calling edit on the view. Then I reenable the controls triggered by rowInserted signal, which happens really when the data is commited, so it reenables controls at the right time. By the way, I was using QSqlRelationalTableModel itself, not a
Re: [PyQt] Limit the height of a Layout
You should be able to 'setMaximumHeight' you can also use the setSizePolicy and set the widgets size policy to what you want. And there is a method for QBoxLayout where you set the 'stretch factor' when you add a widget, so that certain widgets will stretch preferentially to others. Maybe you could make a short example of your layout and somebody will fix it. I find the layouts of Qt to be really convenient without resorting to the designer. But at the same time, now that I am more familiar with Qt, I use the designer to whip up some really quick examples. mbs ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
