java - GXT 3 change tab style (add css) -

-

gxt 3 has function, adds tab tabpanel

      tabpanel.add(html, new tabitemconfig(title, true));

i have change style of name of tab , contents. these have no effect: 

           tabpanel.setstylename("tab-title", true);            html.setstylename("tab-title", true);

tabitemconfig has no method change style. how achieve?...

i see you've found solution, leave here, because it's quite simple , may save somebody's time:

class stylabletabpanel extends tabpanel {     public void applytabstyles(widget widget, string styles) {         finditem(getwidgetindex(widget)).applystyles(styles);     } }

then:

tabpanel = new stylabletabpanel(); html shorttext = new html("lorem ipsum..."); tabpanel.add(shorttext, "short text"); html longtext = new html("<b>lorem ipsum dolor sit amet...</b>"); tabpanel.add(longtext, "long text"); tabpanel.applytabstyles(longtext, "margin-left: 300px;");

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
