Font variable

A font can be created from a Font variable.
To define the font characteristics, use:
This font can be used:

Number of characters

If the maximum number of characters that was specified is less than the number of characters currently found in the control:
  • The content of the control is not modified on the screen.
  • The value of the control includes all the characters displayed in the control.

Multiline edit control

If the maximum number of characters allowed in a multiline edit control is changed with the Size property, you will be able to assign a text containing more characters than the number that was defined. For example:
// "EDT_Address" is a multiline edit control
EDT_Address.Size = 5
EDT_Address = "ABCDEFGHI" 
// "EDT_Address" contains "ABCDEFGHI"

Control with input mask

The Size property must not be used to change the maximum number of characters in controls with an input mask. Indeed, the maximum number of characters found in the control depends on the input mask defined for this control.

Limits

In HFSQL data files, the Size property applies only to text and time items.
In a report, the Size property can only be used on Static controls.
WEBDEV - Server code In a page, the Size property (in read-only mode) applies only to:
  • edit controls,
  • tables.
Minimum version required
  • Version 11
