I have come to see that Sencha Touch framework is improving noticeably. Since I couldn't see something like what I want, I wanted to ask here and see if it's possible. I would like to hear your opinion on how to do some image change animation when the image is touched. When you touch the image, another image will animate growing from the middle.
Actually I also want to detect (if possible) the location of the touch on the image (Things I could do on iOS).
Is this possible? If so, any advice is appreciated.
Thanks
Panel has some properties to find out location of the touch:
var Xscroll = somePanel.scroller.offset.x;
var Yscroll = somePanel.scroller.offset.y;
Also, for your animation, you can do something like this:
Have 1 image on your 1st panel (make that image fit to the panel and keep it to background) like this:
JS:
App.somePanel= new Ext.Panel({
cls: 'somePanel',
html: '<h1>Welcome to my app!</h1>',
//some other properties
});
CSS:
.somePanel {
background-image: url(http://somesite.com/someimage.png);
background-repeat: no-repeat;
background-size: 100% 100%;
}
Have second panel like that.
On some event on the first panel do:
Hide that panel with animation
Show the second panel with animation
The list of animations is given in Sencha Touch API

My logo slider shows every slide vertically when loading and it looks terrible when loading and then when loaded it forms correctly.
Can someone please let me know how to get rid of this problem please? Here's where the slider is located http://www.customlogoshop.com/logo-design
Thanks!
You could try to hide the images like this:
.logo-slider img {
display: none;
}
and make them visible again as soon as slickjs initialized the slider:
.logo-slider.slick-initialized img {
display: block;
}
I have a Rally.ui.cardboard.CardBoard as an item in an Ext.tab.Panel. When there are enough cards to cause a vertical scrollbar to appear, eating 16px of width, instead of fitting the new width dynamically, a horizontal scrollbar appears too. This doesn't happen when the CardBoard is rendered to document.body.
I've been looking for the right set of config options to make the TabPanel and its child items[] resize automatically. After two days trying in vain, I'm about to give up and just force a width of 1902px for PCs and 2862px for Macs. If anyone has a better idea, I'm more than willing to try it... anything at this point.
We could find no way to do this through config options alone, so we ended up listening to the App's own resize event and updated the panel size. In the App config we have this, and it does the trick:
listeners: {
resize: function( app, width, height, oldWidth, oldHeight, eOpts ) {
if (app.TabPanel) {
app.TabPanel.setWidth(window.innerWidth);
app.TabPanel.setHeight(window.innerHeight);
}
}
}
If anyone has a better solution that only uses config options and the framework does the resizing, I'd still like to see it, as the above is an ugly hack even if it works.
I made a vertical carousel which consists of images that when clicked should be visible fullscreen. But the problem is i'm not able to figure out how to make sure the fullscreen images are preloaded or something and works like the thumbnail images(getting preloaded).
I'm not sure what approach to follow for preloading the fullscreen images using css background and how to make sure the images fadeIn or just some transition when i click on the thumbnail in the carousel.
Please have a look at the following link where my code is uploaded.

If its convenient,feel free to check the script by checking the source.
Help would be appreciated. Thanks!
Found this post and figured it might help you, Preloading images with jQuery
Try and post some of the code in your body for future reference. :)
Quick and easy:
function preload(arrayOfImages) {
$(arrayOfImages).each(function(){
$('<img/>')[0].src = this;
// Alternatively you could use:
// (new Image()).src = this;
});
}
// Usage:
preload([
'img/imageName.jpg',
'img/anotherOne.jpg',
'img/blahblahblah.jpg'
]);
Or, if you want a jQuery plugin:
$.fn.preload = function() {
this.each(function(){
$('<img/>')[0].src = this;
});
}
// Usage:
$(['img1.jpg','img2.jpg','img3.jpg']).preload();
Alternatively, if you want to stick purely with CSS check out this page: http://perishablepress.com/3-ways-preload-images-css-javascript-ajax/ You can just have the background image be positioned off screen then come on screen when needed.
#preload-01 { background: url(http://domain.tld/image-01.png) no-repeat -9999px -9999px; }
#preload-02 { background: url(http://domain.tld/image-02.png) no-repeat -9999px -9999px; }
#preload-03 { background: url(http://domain.tld/image-03.png) no-repeat -9999px -9999px; }
I want to display a ListView in WinJS which never shows it's own scroll bar. I want it instead to grow horizontally into its parent container. The way in which I've implement it is basically by setting the min-width css property on the ListView. On initial load, this works flawlessly. When additional data is loaded into the backing data source (a WinJS.Binding.List in this case), I expect the ListView to draw the elements and resize itself. Instead, the ListView draws the elements and adds its own scroll horizontal bar. After about a second or two, suddenly the ListView is resized automatically and fits into the parent container.
How can I have this resize happen immediately after elements have been added? Force layout won't work because it redraws every single item and I am populating a lot of elements into this ListView.
I agree with Dominic, that you should try to listen to the loadingStateChanged event on the listview control. There is a chance that it won't fire immediately, in which case i would show the progress element over your list and wait for it to redraw, then remove the progress.
I used a technique I found on how to detect overflow on a div. Basically, after I add all the new data items, I ensure that increase the size of the ListView's parent div until the ListView div doesn't have overflow anymore.
Edit: so in the end I decided against this strategy because of the advice as a result of this post. I looked at the built in Grid project template and figured out how to ensure that the list view fits in the whole screen properly. I used the following CSS.
#listid{
height: 100%;
position: relative;
width: 100%;
z-index: 0;
}
#section[role=main]{
margin-left: 0;
}
#listid .win-horizontal.win-viewport .win-surface {
margin-left: 120px;
margin-right: 115px;
}
I am trying to slide a Panel from the bottom, so that it covers the entire viewport, like the Bookmarks panel in iOS Safari. This is similar to the ActionSheet, but fulscreen, and without the dark frame around it.
this.advSearch = Ext.ComponentMgr.create({xtype: 'advanced_search', itemId: 'pnlAdvancedSearch'});
this.advSearch.autoRender = true;
this.advSearch.show({type: 'slide', direction: 'up'});
This sort of works, but the new panel doesn't fill the whole screen, and parts of it appear behind the background panel. I've tried various layouts, including fit, vbox, with varying degrees of ugliness, but the root problem seems to be that the panel doesn't know how tall it needs to be. Maybe because it doesn't have a container?
Any suggestions? Is this even the right approach, or should I try to hack the ActionSheet to expand to fullscreen, and show without the border?
Thanks.
Because your panel is floating (or I presume it is), you will need to give the panel a fixed height in Sencha Touch 1. You are very restricted in that respect. This following code should work:
var sheet = new Ext.Sheet({
html: 'hello',
style: 'color:#fff',
height: window.innerHeight,
stretchX: true
});
// replace this show with your animation
sheet.show();
As you can see, I give it a fixed height of the window and then stretch it on the X axis (y doesn't work).
