A control's text size is specified in the control's TextSize property. PowerBuilder saves the text size in points, using negative numbers.
For example, if you define the text size for the StaticText control st_prompt to be 12 points, PowerBuilder sets the value of st_prompt's TextSize property to –12. PowerBuilder uses negative numbers to record point size for compatibility with previous releases, which saved text size in pixels as positive numbers.
If you want to change the point size of text at runtime in a script, remember to use a negative value. For example, to change the point size for st_prompt to 14 points, code:
st_prompt.TextSize = -14
You can specify text size in pixels if you want, by using positive numbers. The following statement sets the text size to be 14 pixels:
st_prompt.TextSize = 14
