A UICuesEventArgs specifies which user interface feature changed and its new value.

The ChangeUICues event occurs when the user interface changes by showing or hiding focus indicators or keyboard cues. This is usually when the user presses the TAB, ALT, or F10 keys.

For information about the event model, see Events and Delegates.

The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the ChangeUICues event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of a type that inherits from Control, such as a Button or ComboBox. Then name the instance Control1 and ensure that the event handler is associated with the ChangeUICues event.


private void Control1_ChangeUICues(Object sender, UICuesEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ShowFocus", e.ShowFocus );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ShowKeyboard", e.ShowKeyboard );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ChangeFocus", e.ChangeFocus );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ChangeKeyboard", e.ChangeKeyboard );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Changed", e.Changed );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ChangeUICues Event" );
}
