[[#LPP-5447] DHTML: inputtext and clickable - OpenLaszlo
Jira](http://jira.openlaszlo.org/jira/browse/LPP-5447)
What is the difference between LzInputTextSprite/__setglobalclickable
and LzMouseKernel.setGlobalClickable? In particular, the latter just
turns off the whole click tree by hiding the root of the tree (which
seems should be pretty efficient) and the latter turns off only divs
that have the class `lzclickdiv` by modifying the CSS style rule
associated with that class (which seems might be more expensive). Why
the two different methods?
LzInputTextSprite/__setglobalclickable() is used by inputtexts to
disable clickable. Since inputtexts currently bind into the click div
(see LzInputTextSprite.__show) the clickdiv itself can't be hidden - or
else the inputtext would be hidden also.
LzMouseKernel.setGlobalClickable() is used by the html tag to disable
the click tree so it doesn't interfere with an iframe's.
Can you explain the purpose of __lastShown, __focusedSprite, and
__lastfocus? I can't follow what these are trying to do.
__lastshown tracks the last inputtext to be shown by __show(), and is
used to hide the currently showing inputtext.
__focusedSprite tracks the last inputtext to be focused, and is used to
work around bugs in firefox's focus management and prevent
spurious/extra onfocus/blur events from being sent.
__lastfocus holds a reference to the last inputtext to be selected - by
select() or setSelection(). It's used as a callback (see setTimout())
to work around a bug in IE where a field can't be selected immediately
after it's focused.
Complicated, no? Since you're in there, can you please add these notes
as comments? Thanks!
