Description

Calculates width of text.
The plugin uses system font rendering to calculate width. This may be different from what FileMaker renders with it's own engine.
You can use the measured size to detect if text fits a field.

Mac result in logical points, but on Windows in pixels.

Examples

Calculate width of Hello World:

MBS( "Font.CalculateTextWidth"; "Hello World" )

Calculate with Arial

MBS( "Font.CalculateTextWidth"; "Hello World"; "Arial"; 12 )
# e.g. 61 on Windows, 61,7 on Mac
