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.

Opening a dialog to show color samples is interesting but now we want to do something with the selected color.

Signals and Slots are used for communication between objects.

Our next example will add a new Push Button. When it is clicked, a built in dialog box will be displayed that allows the user to select a color.

This article will focus on how to build and run our first example.
