for example, the following code checks to see if the selected text is white and if it is, sets it to black: You can also get and set the color of the selected text using the SelectionTextColor property. To update the text in a styled TextArea, it is safest to use the SelectionStart, SelectionLength, and SelectedText properties to update text selections. All the text will then be styled uniformly. Please note that if a TextArea contains more than one style, font, or font size and you reassign the value of the Text property, you will lose the styled formatting of the text substrings. If the selected text has more than one style, font, or size, you can select individual characters using the SelStart and SelLength properties to determine which styles, fonts, and sizes are in use. If the selected text has more than one font size, the SelectionFontSize property will be zero. If the selected text uses more than one font, SelTextFont will be an empty string. To set the font of the selected text, set the SelectionFontName property to the name of the font. Getting and setting the selected text font and font size work the same way using the SelectionFontName and SelectionFontSize properties. Otherwise, these properties will be False.
The SelectionBold, SelectionItalic, and SelectionUnderline properties will be True if all of the selected characters are in the style being checked. For example, if you want to add the bold style to the selected text in TextArea1, use this syntax: To set the style, assign True to the property. These properties are set automatically at runtime when text is selected in a TextArea. The SelectionBold, SelectionTextColor, SelectionItalic, and SelectionUnderline properties can be used to both set the style of the selected text and get the style of the selected text. In order to display styled text in a TextArea, the TextArea's AllowStyledText property must be True. TextEdit is an abstract class and it is not intended to be instantiated. TextField is the single-line text control. TextArea inherits from TextEdit, the base class for both TextArea and TextField. Styled text can also be managed independently of a TextArea using the StyledText class (see below for more information). Styled text can be printed using the StyledTextPrinter class. For single-line text fields, use the TextField control. A TextArea control can contain multiple lines of text and can display mixed fonts, font sizes, and styles.
