This example uses a QTreeView with the QFileSystemModel to display the structure of a file system.

A QTreeView arranges a group of data elements based on a parent-child relationship. Top level items can be empty or have child items. Items which do have children can be expanded or collapsed and the child elements will be displayed or hidden. The QStandardItemModel will be used to store the data.

The QTableView class is used to display multiple rows and columns of data. This view makes sense when the data resides in a multi-dimensional container or a database. Since our data is stored in an SQL table we will use the QSqlTableModel to populate the view.

This example shows how to use a QListView to display a list of strings in a view where each row contains one item. Users can add, edit, and remove entries and the list will remain sorted. A string model is used to store the data and a proxy model is used to automatically sort the data.

This example shows several different frame styles which can be added to a variety of GUI widgets. A frame can also be used to group a collection of related widgets. The purpose of using a frame is to change the visual appearance of the boarder around a single widget or a group of widgets.

A common requirement for applications is to save user settings when an application is closed and then restore them the next time the application is opened. This example shows how to save information about the application and text the user has entered.

This example will show how to use check boxes and radio buttons on the pages of a Tab Widget. The layout of a tab page may contain any number of controls and the number of pages is unlimited.

The code in this example compares the three built in GUI widgets which are used to edit text. Each of these controls offers slightly different functionality and features.

The QLineEdit control appears in a user interface when a word or single line of text should be entered by the user. It is common for the entry to be a word which starts with the same letter. This example will show how to implement a completer which offers a list of predefined words for auto completion.

The QCalendarWidget displays a monthly calendar which allows a user a convenient way to select a date. In this example we will show how to change the colors for various days of the week.

The QCalendarWidget displays a monthly calendar which allows a user a convenient way to select a date. In this example we will show how to modify which day of the week the calendar should start on and various other appearance settings.

The QCalendarWidget displays a monthly calendar which allows a user a convenient way to select a date. This code shows how to set the minimum and maximum date range for a calendar.

The CopperSpice documentation is extensive, so let’s break it down into some smaller components. We have multiple tutorials and videos about programming and using C++. This article will explain where to find all of these.

This example shows how to use two other static methods in QFileDialog for the user to select a directory or file name.

This example shows how to use two other static methods in QInputDialog for the user to enter an item from a fixed list or some text.
