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.

In the next few examples we will look at how to use several different static methods provided by the CopperSpice GUI library.

The idea in this code is to set up a relationship between a QSpinBox, QProgressBar, QSlider, and a QDial. The progress bar is read only and can only react to value changes. Modifying the value of the other three widgets will cause all four to be updated automatically.

This example will show how to configure a QLineEdit when the user needs to enter a password.

In these next few examples let’s look at some of the properties for a QLineEdit. This example will show how to add a mask to the edit widget to restrict the formatting.
