extjs - Add a CSS class to the TAB in TabBar, not the tab it self -


here screenshot visualize want do.enter image description here

there tab iconless (between exit , project). blue highlighted line element in inspector.

my goal set tab's width in tabbar , not in tabpanel 5px. act has spacer between tabs' icons.

i tried manually add css class create specific rule pointing element , inside rule set width 5px !important tag.

.x-tab .x-tab-normal .x-item-disabled .x-iconalign-center .x-tab-icon .x-layout-box-item .x-stretched {   width:5px !important; }

sadly never found way add class @ particular level of component hierarchy.

so tried replace existing css class of component (.x-item-disabled). changed .x-item-disabled .fake , created css rule accordingly... did not work , has in first case, component's css classes in inspector did not changed @ all..

i'm pretty sure need way since it's not sencha allows do.

can me out plz?

ext.tab.bar , ext.tab.tab private classes , ext.tab.panel not seem expose feature, guess @ moment there no simple way ask. tabs built based on panel items configuration, data pass in not directly mapped them. indeed if apply cls or style property item configuration, goes content of panel, not associated tab. can modify tab after panel has been initialized:

try this:

ext.create('ext.tabpanel', {     fullscreen: true,     tabbarposition: 'bottom',      defaults: {         stylehtmlcontent: true     },      items: [         {             title: 'home',             iconcls: 'home',             html: 'home screen'         },         {             title: '',             iconcls: 'dummy',             html: ''         },         {             title: 'contact',             iconcls: 'user',             html: 'contact screen'         }     ],      initialize: function() {         // spacer position, it's ugly works         // without extending sencha components         var spacer = this.gettabbar().getat(1);         // of course here apply css class         // if prefer         spacer.setstyle('width:5px; min-width:5px;');         // let's disable button         spacer.setdisabled(true);         // , remove icon since mandatory in panel         // config don't want         spacer.seticon(false);     }  });

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
