How to change the font size and style on run time

Question

dear all
i try to change the font style and font size on runtime. I did the following:
1- i created an item(:font_size) in which i will write the size of the font for the the other item ('customer_name')
2 on the post_change trigger for 'font_size' i write this code
SET_ITEM_PROPERTY('customer_name',FONT_size,(:font_size);
i write 12 then then font size changed , then i write 18 , the size does not change. and when i write any value , no change happens. I do not know why
the second problem is how to change the font style
i made three checkbooks (bold,italic,underline)
on the trugger when_checkbox_checked i write
     IF :BOLD = 'B' THEN
     SET_ITEM_PROPERTY('N_SAMPLE',FONT_STYLE,'BOLD');
     ELSE
SET_ITEM_PROPERTY('N_SAMPLE',FONT_STYLE,'REGULAR');
     END IF;     
no change happend at all.
please help

Hi friend,
it's a really really strange tip... May be it's a Forms bug? I've tried with set_item_property..and.. you're right, it doesn't work..
So.. you can try making this:
- create a visual attribute with an specific font size....
- use the
SET_ITEM_INSTANCE_PROPERTY('block.item',CURRENT_RECORD,VISUAL_ATTRIBUTE,'you_visual_attribute');
and call it from psot-change....
It works
Hope it helps,
Jose.
