I am learning the PyQt5 framework and attempting to build a QListView of items with a checkbox in front of each item. Can someone please point me in the right direction? A possible option is to enable the flag Qt::ItemIsUserCheckableand overwrite the data and setData methods when the role is Qt::CheckStateRoleto store the data we create a dictionary. Learn more.

I am new to Qt coming from iOS programming and am doing an image viewer app as a learning project.

Most examples assume that one knows this most basic thing I guess. Can someone post or point me to a barebones example. Constructor example: mytablemodel. But before going this way, are you getting your images from the database? You might also consider implementing a QStyledItemDelegate to show what you want rather than modify the model.

QSqlQueryModel can also be used to access a database programmatically, without binding it to a view:. Since salary is the 2nd column or column index 1we can rewrite the last line as follows:.

The model is read-only by default. To make it read-write, you must subclass it and reimplement setData and flags. Another option is to use QSqlTableModelwhich provides a read-write model based on a single database table.

The querymodel example illustrates how to use QSqlQueryModel to display the result of a query. It also shows how to subclass QSqlQueryModel to customize the contents of the data before showing it to the user, and how to create a read-write model based on QSqlQueryModel. If the database doesn't return the number of selected rows in a query, the model will fetch rows incrementally.

See fetchMore for more information. Returns true if it is possible to read more rows from the database. This only affects databases that don't report back the size of a query see QSqlDriver::hasFeature.

If item is out of bounds or if an error occurred, an invalid QVariant is returned. Fetches more rows from a database. Returns the header data for the given role in the section of the header with the specified orientation. Returns the index of the value in the database result set for the given item in the model.

The return value is identical to item if no columns or rows have been inserted, removed, or moved around. Returns an invalid model index if item is out of bounds or if item does not point to a value in the result set.

Inserts count columns into the model at position column. The parent parameter must always be an invalid QModelIndexsince the model does not support parent-child relationships.Your browser does not seem to support JavaScript.

Mikeeeeee "I understand this. I understand this. But I have many composite filters. I need to make many separated filters. Mikeeeeee If you want several filters, you offer several filters to your user. Does that answer your question? It's not answer. Mikeeeeee You can combine them into one.

You measured it? Or how do you know it will be slow? Doing complete filtering in SQL will be different: you will only load data in your app which matches all filters - way less memory consumption and faster operation. Qt Forum.

See also QSqlTableModel. Inserts count columns into the model at position column.English French. As a programmer who started his programming life with PHP and web technologies, QSqlTableModel is a great class to interact with database tables.

It is very easy to insert, delete or update an entry with it. This code is from one of my projects which won a silver medal in an international informatics contest. Anyway, let's look at the code. In the second line:. Sets the database table on which the model operates to tableName. Does not select data from the table, but fetches its field information. I love Qt's documentation, really.

After this function, in line four, we use "select" function, to select the data in the table. The function in the line above sets the strategy for editing values in the database to one of various editing strategies in Qt. But be careful, this will revert any pending changes.

In Qt we have three edit strategies:. But I plan to give examples of them later. But I prefer to hide a column instead of removing it. If you remove a column, when you try to edit the entries in the table via a table view, it says: "QSqlQuery::value: not positioned on a valid record". Anyway, let's continue. These three line helps you to make more explanatory interfaces by setting a caption.

It is useful when you use a view, e. As I mentioned above, I prefer to hide the column I don't want to show so I do that in the third line. Jump to: navigationsearch.
