java - Best way to style GWT widgets in a library -

-

i'm developing widgets library internal use @ company work for.

i don't know what's recommended way style widgets.

there @ least these ways:

  • use widget.setprimarystylename , let user provide external css. use maven archetypes build applications can provide default styles. anyway don't much.

  • use gwt 2.0 cssresourcebundle. can compile css module , optimized (and can browser-dependant too).

  • provide module styling. default gwt themes. don't know how works.

i want to:

  • make components cohesive can (don't depend on externally included css's)
  • leave open door modify styles (if want change way widget looks in concrete application).

what's experience in subject?

note: if looking definitive answer through answers , comments. there different ideas , ones. choose best :)

i think best way provide styles in module. way able restyle, or add "themes" controls.

i'm doing similar project hosted on github (http://github.com/markovuksanovic/gwt-styles), might want check out. can download jar file, include in project , specify in module xml wanna use style.. sth like

<inherits name='gwt.theme.flick.flick'/>

i suggest use new module styles can switch among styles... (just change inherits tag). so, example, if 1 of widgets used css class "my-widget", have "style" module (or multiple modules) define css class (in css file) - way have multiple modules implement css class , switching amongst them easy changing module name in inherits tag. way nicely decoupled code - styles independent of technical implementation of widgets. if have more questions, feel free ask.

p.s. forgot mention above - pay close attention on how style module built (build.xml), it's little tricky. can find more information creating modules @ following lication http://developerlife.com/tutorials/?p=229

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
