grid size in percentage

Hi,

as of now i am using
obj.setControlSize(780, 180);
for a screen resolution of 1024x768
{my app is old frameset based}
this works fine.....WITH THE RESOLUTION

however i want to make the grid resolution independent
is using percentages the solution to it?
if yes....
does setControlSize support it?

obj.setStyle("width", "100%");

thanks alex this seems to work fine
would like to add,the product is awesome
i managed to enter the good books of the client bcoz of it


thanks :)
