PowerBuilder – Fontheight method in Expressions
An enhancement was put into PB12.1 dealing with determining the height of a datawindow column based on its font setting. It’s called Fontheight and takes a string parameter. Unfortunately there does not appear to be any documentation on it in the PB help files (I’m looking in PB12.5). You can see a reference to it in the list of methods in the expression painter.
Anyway, to use it to dynamically set the height of a datawindow column based on its font place the following in the height property expression:
fontheight({colname}[0])
// replace {colname} with the specific column name
To get the value in a script you can use the Evaluate.
string ls_val
ls_val = dw_1.Describe("Evaluate('fontheight({colname}', 1)")
This gets the value based on the font of column ‘{colname}’ in row 1.
