| Default behavior: | None |

Description
If the parent widget of a contained form is attached to a form border and is resized, it may be necessary to change the contained form as well. For example, if the widget is becomes too small to display the contents of the contained form, you could display a different form.
Using the Resized Trigger
The following ProcScript loads one of two forms in a Form Container, depending on the available width.
trigger Resized
params
numeric widthPx : in
numeric heightPx : in
endparams
if (widthPx > 300)
; Load form with wide layout in this Form Container
@$fieldname = "CUST_WIDE"
else
; Load form with narrow layout in this Form Container
@$fieldname = "CUST_NARROW"
endif
end; Resized
