So, I have a panel in Sencha Touch and I have an image which I want to display as a component in that panel. I have tried several things along the lines of:
logo = {
xtype: 'component',
autoEl: {
src: 'http://addressofmyimage.com/image.png',
tag: 'img',
style: { height: 100, width: 100 }
}
};
Then adding above component as an item in my panel. No image is displayed. All of my other components are displayed but not the image. Not even a broken-image-link icon. I can't figure this out...
I'd rather not just insert raw html, as I cannot format that as I wish.
Probably better off using a panel to display the image itself. Replace the above code with...
logo = {
xtype: 'panel',
html: '<img style="height: 100px; width: 100px;" src="http://addressofmyimage.com/image.png" />'
};
You could override the Component's getElConfig method and return what you have in your autoEl object.
{
xtype: 'component',
getElConfig : function() {
return {tag: 'img',
src: 'http://addressofmyimage.com/image.png',
style: { height: 100, width: 100 },
id: this.id};
}
}
That method is used when the component is rendered to get the makeup of the underlying element.
You can use src.sencha.io API to resize image as you wish. Belowed example works for me.
{
xtype: 'image',
src: 'http://src.sencha.io/100/100/http://www.skinet.com/skiing/files/imagecache/gallery_image/_images/201107/windells_hood.jpg',
height: 100
}
You can find documentation here.

I have the following custom component build
Ext.define('TRA.view.MainMenuItemView', {
xtype: 'mainmenuitem',
extend: 'Ext.Container',
text: 'Menu text',
icon: './resources/icons/Icon.png',
tap: function(){
},
config: {
layout: {
type: 'vbox',
pack: 'center',
align: 'center'
},
items: [
{
width: '115px',
height: '115px',
style: 'border-radius: 50%; background-color: #e4e4e6',
items: [
{
xtype: 'image',
src: '',
width: '65px',
height: '65px',
centered: true
}
]
},
{
xtype: 'label',
html: '',
margin: '5px 0',
style: 'color: #455560; text-align: center; text-transform: uppercase; font-weight: bold;'
}
]
},
initialize: function() {
var me = this;
me.callParent(arguments);
//set icon
me.getAt(0).getAt(0).setSrc(me.icon);
//set text
me.getAt(1).setHtml(me.text);
//setup componet event
me.element.onAfter('tap', me.tap);
}
})
and I'm using it on other containers as this
{
xtype: 'mainmenuitem',
text: 'Signal Coverage',
icon: './resources/images/icon-signal-coverage.png',
tap: function() {
var nav = Ext.ComponentQuery.query('#mainnavigationview')[0];
nav.push({
title: 'Signal Coverage',
html: 'test Signal Coverage'
});
}
}
Quite strangely it all works all well normally except when I build the sencha app for native or for web build using sencha cmd
sencha app build production
the production version does not overwrite icon and text properties of my custom component. while it all works well on normal version. what could be issue?
first of all, some ideas to make your code easier readable for others:
1) the first item does neither have an xtype nor does a defaultType define it
2) width: '115px', height: '115px', just could be width:115,height115
3) instead of me.getAt().getAt() define an itemId for these and use me.down('#theItemId')
3a) or use Ext.Component to extend from and add a template with references. That way it's me.referenceElement
4) me.onAfter('tap',... not sure if this will work on an item that does not support the tap event. you might need to set a tap event to me.element and from there you can use a beforetap
5) instead of add me.getAt().getAt().setText(me.text) use the updateText: function(newValue) {this.getAt().getAt().setText(newValue)}
Same for the icon
then my personal opion
Personally I never expected this code to run anyways. But the fix might be to write me.config.icon and me.config.text
Solution
It's a matter of timing. While the constructor runs there are no icon or text defined inside the config.
This happends only on initialize. there you have them inside the config.
go and add icon: null, text: '' to the config of the component and it will word with getter and setter.
I have a list which contains main menu of my mobile app and is visible when user swipes to right or clicks on menu icon. I want to have the background of this list and hence main menu to be blurred.
I checked out the css filter:blur property and it can be done using that but you need to have an extra div under the div which has your content and apply filter:blur to it as shown in this Codepen
Below is my list code for sencha touch
Ext.define('MobileApp.view.SlideList', {
extend: 'Ext.List',
xtype: 'slidelist',
config: {
cls: 'slide1',
variableHeights: true,
onItemDisclosure: true,
store: 'SlideListStore',
itemTpl: ['<div class="slideImg" style="background-image:url(resources/images/{img});"></div>',
'{title}',
'<div class="settingImg" id="settingImg" style="background-image:url(resources/icons/nw-icons/settings.png);"></div>'].join(''),
listeners: {
initialize: function (comp, eOpts) {
comp.element.on(
'swipe',
function (event, node, options, eOpts)
{
/*send event as a argument to get direction of swipe*/
this.fireEvent('swipe', event);
},
comp
);
}
}
}
});
I cant figure out where to place the extra div and apply filter:blur to it. Any pointers will be helpful.
Is this what you were trying to achieve https://fiddle.sencha.com/#fiddle/4tb
Here is how you can accomplish this
Add an empty div as html property of the list
remove the background of the list
add css to blur the image
.setMyBackground {
position: fixed;
left: 0;
right: 0;
display: block;
background-image: url('http://666a658c624a3c03a6b2-25cda059d975d2f318c03e90bcf17c40.r92.cf1.rackcdn.com/unsplash_527bf56961712_1.JPG');
width:100%;
height: 100%;
-webkit-filter: blur(5px);
-moz-filter: blur(5px);
-o-filter: blur(5px);
-ms-filter: blur(5px);
filter: blur(5px);
z-index:-1;
}
.slide1{ background:none;}
Sencha Touch 2 includes Ext.util.Droppable and Ext.util.Draggable classes. Does anyone have a simple example showing how basic drag and drop behavior works?
It seems any component can be made draggable with the 'draggable' config option. Here I create a simple Panel with a draggable image component:
Ext.create("Ext.Panel", {
fullscreen: true,
items: [
{
xtype: 'image',
src: 'http://www.sencha.com/assets/images/sencha-avatar-64x64.png',
height: 64,
width: 64,
left: '10px',
top: '10px',
draggable: {
direction: 'both',
},
}
]
});
and that works fine: the component can now be dragged around inside the Panel.
But how do we now make a simple "drop target" using the Ext.util.Droppable class?
I have a list and I want have two icons per line using onItemDisclosure. How can I do that?
I don't know how to implement onItemDisclousre() on two icons but probably this will help you.
In the following example i have put an image on every itemlist and functionality is provided on itemtap event. This will serve the purpose of doing multiple tasks with single itemlist.
//demo.js
Ext.define("Stackoverflow.view.demo", {
extend: "Ext.Container",
requires:"Ext.dataview.List",
alias: "widget.demo",
config: {
layout: {
type: 'fit'
},
items: [
{
xtype: "list",
store: "store",
itemId:"samplelist",
loadingText: "Loading Notes...",
emptyText: "<div class=\"notes-list-empty-text\">No notes found.</div>",
onItemDisclosure: true,
itemTpl:"<div class='x-button related-btn' btnType='related' style='border: none; background: url(\"a.png\") no-repeat;'></div>"+
"<div class=\"list-item-title\">{title}</div>"
grouped: true
}
],
listeners:
[
{
delegate: "#samplelist",
event: "disclose",
fn: "onDiscloseTap"
}
]
},
onDiscloseTap: function (list, record, target, index, evt, options) {
this.fireEvent('ondisclosuretap', this, record);
}
});
// Democontrol.js
Ext.define("Stackoverflow.controller.Democontrol", {
extend: "Ext.app.Controller",
config: {
refs: {
// We're going to lookup our views by xtype.
Demo: "demo",
Demo1: "demo list",
},
control: {
Demo: {
ondisclosuretap: "Disclosure",
},
Demo1: {
itemtap:"imagetap"
}
}
},
Disclosure: function (list, record,target,index,e,obj) {
Ext.Msg.alert('','Disclosure Tap');
},
imagetap: function (dataview,index,list,record, tar, obj) {
tappedItem = tar.getTarget('div.x-button');
btntype = tappedItem.getAttribute('btnType');
if(btntype == 'related')
{
Ext.Msg.alert('','Image/Icon Tap');
}
},
// Base Class functions.
launch: function () {
this.callParent(arguments);
},
init: function () {
this.callParent(arguments);
}
});
//app.css
.related-btn
{
width: 100px;
height: 100px;
position: absolute;
bottom: 0.85em;
right: 2.50em;
-webkit-box-shadow: none;
}
Hope this will help you.
bye.
You can do this by manually adding a disclosure icon inside of itemTpl on your list items. Add this inside of your view:
{
xtype: 'list',
onItemDisclosure: true,
cls: 'my-list-cls',
itemTpl: [
'<div class="x-list x-list-disclosure check-mark" style="right: 48px"></div>'
]
}
Notice that the div inside of itemTpl has the CSS class "x-list x-list-disclosure check-mark". I set style="right: 48px" because I want this icon to appear on the left side of the regular disclosure icon (the one with the right arrow) and this rule leaves enough room on the right to show the arrow icon.
Then, in your app.scss, add:
.my-list-cls {
.x-list.check-mark.x-list-disclosure:before {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
content: '3';
font-family: 'Pictos';
color: #fff;
text-align: center;
text-shadow: 0 0 0;
}
}
This controls the styling for your new disclosure icon.
By setting content: '3';, you are changing the icon from the default right arrow to a checkmark. (See all of the available icons here: Pictos fonts).
The result:
It is possible but not easy. In short you have to extend class Ext.dataview.List and/or Ext.dataview.element.List.
The titles on the table view have ellipsis although the horizontal space is huge. I see it in the default-style.css under .x-title .x-innerhtml. What is the proper way to adjust when it ellipses? and also if your feeling frisky the method I should use to find the answer in a situation like this would be helpful. For example, I went to the API doc for sencha and found Ext.String.ellipsis, Ext.util.Format.ellipsis, and Global_CSS.ellipsis. I see the documentation but am not sure how to approach actually changing the way ellipsis are handled.
items: [
{
xtype: 'container',
title: 'Bla Mobile',
layout: {
type: 'vbox',
pack: 'start',
align: 'center'
},
EDIT:
I added this to my style.css to fix it:
.x-title { padding:0 .3em; }
.x-title .x-innerhtml { padding: 0; }
This seems to ba a bug in webkit, I came up with this solution:
.x-title .x-innerhtml:after {
content: '';
display: inline-block;
width: .3em; /* equal to the amount of padding on the element */
}
