Re: Trying to optimize a widget that is used a LOT of times...

[Thomas Broyer]

I'd rather use option C or D:

C: use Widget rather than Composite

D: use a HTML widget (possibly HTMLPanel) as root

You don't need to use a FocusPanel to listener to mouse events, addDomHandler is public.

Hello,

I am sorry for the unprecise subject, but I would like to know what should be "the smallest memory consuming" OR "the fastest loading" solution for my widget that I will heavily use (displaying it a hundred times so I think that the little differences should be considered....).

The 2 possibility of the same widget are:

case A:

g:HTMLPanel

   g:Image

   g:Label

   g:Label

case B:

g:FocusPanel

  img

  label

  label

NB:

- img is smaller than g:Image     and     label is smaller than g:Label

 

- I need a special rollover behavior

(cf. images in the attachement, when I rollover, a light background appear...) , that is why I use the Focus panel (case B) in order to use "the MouseOver Event" all over the widget.

- In case A, let say that I need to implement 3 times the same behavior (MouseOver the img, MouseOver the label....) in order to trigger the background effect all over the widget.

Question:

Does SpeedTracer is the only tool to mesure the difference between my 2 solutions OR is it obvious that case B will be faster to load ?

Thanks you for your help,
