Animating dimensions in Sencha Touch 2

由 假装没事ソ 提交于 2019-12-09 13:25:20
问题 I'm trying to animate the height of a dataview, but it's currently just sliding the panel around the viewport instead of keeping it in place and changing it's height. The code is as follows: Ext.Anim.run(el, 'slide', { from: { height: height }, to: { height: newHeight }, out: false, direction: 'up', easing: 'ease-out', duration: 1000 }); For instance, height=200, newHeight=100 will result in the dataview dropping immediately so that it's top is at 200px below the viewport, and then animating

sencha touch i18n basics

由 我的未来我决定 提交于 2019-12-09 11:10:50
问题 How is i18n handled within Sencha touch? (I am talking of localization support for strings, but also of localized components) A more specific question: I have a form that contains a date picker, how do I make sure that the date will be displayed and picked in european format when I access the application using a french android phone? Cheers 回答1: There isn't an official API for i18n in SenchaTouch, yet. Although in Ext 4 there are localization files for all components in the /locale folder.

Accessing nested objects in JSON feed - Sencha Touch

由 ぐ巨炮叔叔 提交于 2019-12-09 00:17:42
问题 I'll begin with the usual disclaimer: new to Sencha Touch/working with JSON, floundering in the dark. Any help or prodding in the right direction is appreciated more than you know! I'm trying to get my app to fetch data from a public Google Spreadsheet JSON feed. From what I've managed to figure out, my current model is based on JSON arrays, NOT nested objects. How do I access and return a nested object? Ext.regModel('Count', { fields: [{name:'$t'}] }); this.list = new Ext.List({ itemTpl: new

Accessing native API/system from Sencha Touch

由 故事扮演 提交于 2019-12-08 23:14:30
Sencha Touch is quite perfect for my project. But in order to call a driver for an hardware barcode scanner on iOS and Android, it would be necessary to have access to the underlying system. Is that somehow possible with Sencha Touch itself when "transforming" it into a native app (the Sencha SDK allows this)? I know that it is possible with PhoneGap. But I'm afraid using all these technologies together (PhoneGap + Sencha touch) could make the UI less responsive, but that is a decisive factor in this project. Edit: in this thread, a user says the following: "you cannot access the native iOS

问题 I'm working on a Sencha Touch project and I'm in need to pack the app with a prepopulated DB. I'm using Cordova-SQLitePlugin (https://github.com/brodysoft/Cordova-SQLitePlugin) as a cordova plugin to use SQLite as a local DB and I've been looking around for ways of achieving my goal of prepopulating the DB but with no success. What I've found are blogs suggesting to copy the DB in a cordova folder and it's supposed to magically work but I haven't had any luck and I'm guessing it has something

问题 I am trying to use an ActionSheet to present the user several options to continue. I want to add a simple text box in the middle of the screen to describe the problem to the user. Is there a simple/standard way to put such a prompt in Sencha-Touch? 回答1: You'll need to do something like this on your overlay ... if (!this.popup) { this.popup = new Ext.Panel({ hideOnMaskTap: false, floating: true, modal: true, centered: true, hideOnMaskTap: false, width: 300, height: 200, styleHtmlContent: true,
