extjs - Sencha touch 2: Set button handler parameter to lunch javascript function -


i using sencha touch o'really example. conference have sessions , speakers associated. imagine have session list when tapped view change session details.

i have view this:

ext.define('myapp.view.session.detail', {  extend: 'ext.container', xtype: 'session',  config: {      layout: 'vbox',     title: '',      items: [         {             flex: 1,             layout: 'fit',             scrollable: 'vertical',             xtype: 'sessioninfo'         },         {             flex: 2,             xtype: 'speakers',             store: 'sessionspeakers',             items: [                 {                     xtype: 'listitemheader',                     cls: 'dark',                     html: 'speakers'                 }             ]         },         {             flex: 1,             xtype: 'button',             text: "decline  button" ,             handler: function () {             /*here want put data session object. example */                  alert({title});                 alert({start_date});                 alert({location});                             }         }     ]  }

}); so, want replace {title} {start_date} {location} corresponding values of current session.

by way in controller have this:

onsessiontap: function(list, idx, el, record) {      var speakerstore = ext.getstore('sessionspeakers'),         speakerids = record.get('speakerids');      speakerstore.clearfilter();     speakerstore.filterby(function(speaker) {         return ext.array.contains(speakerids, speaker.get('id'));     });      if (!this.session) {         this.session = ext.widget('session');     }      this.session.settitle(record.get('title'));     this.getsessioncontainer().push(this.session);     this.getsessioninfo().setrecord(record); },

thanks!!

i resolve it. had create button on runtime. :

in session view:

ext.define('myapp.view.session.detail', {  extend: 'ext.container', xtype: 'session',  config: {      layout: 'vbox',     title: '',      items: [         {             flex: 1,             layout: 'fit',             scrollable: 'vertical',             xtype: 'sessioninfo'         },         {             flex: 2,             xtype: 'speakers',             store: 'sessionspeakers',             items: [                 {                     xtype: 'listitemheader',                     cls: 'dark',                     html: 'speakers'                 }             ]         }     ]  }

});

in session controller:

onsessiontap: function(list, idx, el, record) {      var speakerstore = ext.getstore('sessionspeakers'),         speakerids = record.get('speakerids');      speakerstore.clearfilter();     speakerstore.filterby(function(speaker) {         return ext.array.contains(speakerids, speaker.get('id'));     });      if (!this.session) {         this.session = ext.widget('session');            }     else{                   //to avoid multiple buttons         this.session.removeat(2);     }      this.session.settitle(record.get('title'));     this.session.add(         ext.button.create({             flex: 1,             xtype: 'button',             text:'my button' ,                       handler: function () {                                   alert(record.get('title'));                                 alert(record.get('start_date'));               } })     );     this.getsessioncontainer().push(this.session);     this.getsessioninfo().setrecord(record); },

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
