The intent of this journal is to show a series of short examples to provide C++ developers with a general understanding about how to use the open source CopperSpice libraries.
Article summaries are displayed with the newest one listed first. Our initial article, posted in December 2021, shows how to set up your working environment and then [ more . . . ]
The QTableView class provides another way to display multiple rows of data. A ListView can only display a single column while a TableView can have multiple columns. This view is a good choice when the data resides in a multi-dimensional container or an SQL database.
This example shows how to use a QListView to display a list of strings in a view. One item will be displayed on each row. Users can add, edit, and remove entries and the list will remain sorted. A standard 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.
This example shows how to use two static methods in QInputDialog for the user to enter a number.
This example introduces the QErrorMessage class and one additional message box static method.
