getLineHeight(): Integer; (ListBox) getLineHeight(line: Integer): Integer; (JadeTextEdit)
The getLineHeight method of the ListBox class returns the height in pixels of each list box entry.
If the value of the ListBox class defaultLineHeight property is greater than zero (0), the getLineHeight method returns that value.
The getLineHeight method of the JadeTextEdit class returns the height in pixels of the text editor line specified in the line parameter, which is 1-relative and must therefore be greater than zero (0).
