Specifies the amount of space between lines of text in a field.
set the textHeight of <field> to <pixels>
get the effective textHeight of field "Results"
set the textHeight of field 1 to theLines * the textHeight of field 1
set the textHeight of field 1 to 20
Use the textHeight property to change the appearance of text in a field.
The textHeight property determines how tall each line of a field is, and is equal to the vertical distance in pixels between the baseline of one line and the baseline of the next. The minimum textHeight is 4 pixels.
If you change the field's textSize, LiveCode automatically sets the textHeight to trunc(4/3 * the textSize of field). For example, if the textSize is set to 12, the textHeight is set to 16 by default. If the textSize is set to 14, the textHeight is set to 18. So, if you want to change the textHeight and textSize, set the textSize first, then set the textHeight.
If a field's fixedLineHeight property is false, the textHeight of the field has no effect: in this case, the text height of each line is determined by the size of the largest text in the line, and changing the textHeight doesn't change the spacing of lines.
