A SingleLineEdit is a box in which users can enter a single line of text. A MultiLineEdit is a box in which users can enter more than one line of text.
SingleLineEdits and MultiLineEdits are typically used for input and output of data.
For these controls, you can specify many properties, including:
Whether the box has a border (the Border property)
Whether the box automatically scrolls as needed (AutoHScroll and, for MultiLineEdits, AutoVScroll)
For SingleLineEdits, whether the box is a Password box so asterisks are displayed instead of the actual entry (Password)
The case in which to accept and display the entry (TextCase)
Whether the selection displays when the control does not have focus (Hide Selection)
For more information about properties of these controls, right-click in any tab page in the Properties view and select Help from the pop-up menu.
