Looks good to me. It seems more maintainable too. Compliments Martin for the
I have only a note on what you can do while at that, since the folowing
optimization saves 70% of the cpu time when hovering items!!
- Delayed tooltip creation MUST be done. I committed a patch that introduced
this while optimizing the iconview on 3.3cycle, but reverted due to a simple
'popup appears after leaving window' bug.
With delayed creation you can avoid killing a running preview kio job and
launching another when hovering files. You can notice this odd behavior by
passing the mouse over icons and watching your CPU going 100% when entering
on a fileItem rect.
The current behavior is:
Hover->Immediately launch preview JOB->show popup at700ms.
A safer behavior (tested and working GREAT even on 300MHz cpus) is:
Hover->at 400ms launch the preview JOB->show popup at 700ms.
So if you enter an icon and then enter another before 400ms no preview job is
launched and no job is killed.
I think on listview, where items are continous in Y and the cursor hovers a
lot of them before reaching the target file, this optimization MUST be done,
or else listview will be slow like hell on low end cpus.
Great job Martin!
