Editors

Figure 57: Plain text editor

Many S60 applications involve displaying and processing data in text form. Many of these applications also allow the user to modify or produce new data. The family of editor controls provides the application designer a way to handle these needs in a uniform and efficient way. The AVKON editor controls have been designed to be applied and customized to meet the specific text display and input needs of the application. The editor class, CEikEdwin, is the base to almost all editors.

AVKON provides the following editors:

• text editors - editor controls containing text. They may allow only one or multiple lines of text to be entered. The most basic text editor controls support only unformatted text, but more specialized controls allow text to be formatted or even object embedding.

• numeric editors - restrict the user input to numeric values.

• secret editors - plain text editors designed to allow secure input of secret data, such as passwords or PIN codes

• multi-field numeric editors (MFNEs)- used to display and enter related numeric values, such as time or date. MFNEs are similar to numeric editors; however, depending on the context, they may impose limitations to the values accepted for a field — for example, because the number of days in a month varies between months.
