I was wondering if it's possible to use custom animation in Sencha Touch 2. If I've done my homework correctly, then Sencha Touch by default does not provide any help with animation apart from the fade-in/out, sliders and other simple UI elements.
One would have to use CSS3 for animations, right? I wan't to use an animation (let's say something like this : http://www.w3schools.com/cssref/tryit.asp?filename=trycss3_animation-timing-function3) in my app.
I wan't the animation to load just after the initial loading screen but I'm not sure how to do that. Can someone help me out with the code? ELI5 please,since I'm new to ST, CSS and HTML5.
In your launch function, you need to define you Ext.Anim like so :
anim = Ext.create('Ext.Anim',{
autoClear: false,
from:{'left':'0px'},
to: {'left':'100px'},
delay: 1000,
duration: 1000
});
Then you can run this animation on any component (here on a Ext.Panel) like so :
anim.run(this.getView().element);
Hope this helps
Ok #user1324579 this steps are:
Create a CSS3 class
Create one panel Sencha
On html tag put class CSS
var panel = new Ext.Panel({
id: 'yourIdPanel',
fullscreen: true,
style: 'background-color:#ffffff',
html: '<div class="animation_css_class"></div>'
})
To load you just after the initial loading screen with id panel above or,
var mainPanel = new Ext.Panel({
id:'pnlInicio',
fullscreen:true,
items : [panel],
dockedItems: []
})
I hope these helps. :)

I have an dojo enhanced grid inside a title pane which inturn in Tabcontainer. I am creating a tab container dynamically and painting the title pane which contains grid. For the first time the grid is painted properly but if i close the tab and again try it to open a tabcontainer title pane is painted but grid inside the titlepane is not painted (or rather its not visible) until i do a browser resize.
So anybody have faced similar kind of issue? Please let me know the solution for this.
I tried resize(), update() & startup() methods on grid nothing worked out.
I am kind of stuck please share your thoughts on this.
Thanks,
Vikram
I had the same problem and found a workaround by doing a dojo connect like:
dojo.connect(Datagrid,"_onFetchComplete",DataGrid,"_resize");
So it should automatically be resized, when DataGrid finished loading data.
Hope I could help.
Greeting, Simon
Have you tried setting an absolute height on the Grid?
Which browsers did you try? (I experienced various problems with DataGrid in TabCointainer using IE)
You must call the TabContainer.layout() each time its container is changing size. For doing this, you could 1) monitor DOMEvents onunderflow and onoverflow on containing DOMNode or 2) when container becomes visible (once-n-forall).
Reason why a window.onresize event fixes it is, that the TabContainer hooks on said event and calls its own layout.
In your situation, where the TabController fiddles with TabContainer's panes, there may be missing a 'layoutChildren' somewhere. Optimally, you should place the grid as the first on only child to tab.
After the grid is deployed, it will take an absolute, calculated height - 'inherited' from the TabContainer. This is fired once the TabContainer chooses to resize or instructed to do so.
Manually, you should be able to implement these lines - after re-opening a tab. The script is taken from _Grid.js to illustrate
var grid = dijit.byId('MYGRIDID');
require(["dijit/layout/utils"], function(layerUtils) {
layoutUtils.layoutChildren(grid.domNode,
grid._contentBox,
[grid.tablist, {
domNode: grid.tablistSpacer,
layoutAlign: titleAlign
}, {
domNode: grid.containerNode,
layoutAlign: "client"
}]);
grid._containerContentBox = layoutUtils.marginBox2contentBox(grid.containerNode,
{
domNode: grid.containerNode,
layoutAlign: "client"
});
// note this line in particular
grid.selectedChildWidget.resize(grid._containerContentBox);
}
My issue
I had a similar situation as yours:
Grid is in a titlepane (closed by default).
Grid can be destroyed and re-created on the fly.
Issue appears when user:
opens the pane.
closes the pane.
re-creates the grid.
re-opens the pane.
grid is not visible, until browser window is resized!
My solution
My approach was to force a resize() on my grid whenever the title pane was being opened.
I used code like this, in a place where I had access to both the grid and the panes:
var titlePane = registry.byId("title-pane-id");
var handle = aspect.after(titlePane, "toggle", function(deferred) {
if (titlePane.open) {
grid.resize();
}
});
The dojo/aspect doc
Don't forget to remove the aspect from your grid if you destroy it.
I did this on dojo v1.8.1
My solution is too easy: define on declaration of grid the bold parameter write here:
grid = new EnhancedGrid({id: 'MyIDgrid',
store: dataStore = new ObjectStore({objectStore: myStore}),
structure: structureGrid,
plugins: pluginGrid,
style : 'width: 725px; height: 350px',
autoWidth : true,
**autoHeight : false,height:'200px',**
elasticView : '2'
}, document.createElement('div'));
this resolve all!
Enjoy!
style="height: auto;" will fit the purpose.
I would like to use an actionsheet but am unclear where to place it. I have tried adding it to a button event function but it doesn't show (the modal screen does however). I get a message about ActionSheet#show showing a component that currently doesn't have any container. Please use Ext.Viewport.add() to add this component to the viewport. Not sure how to do that - using Ext.Viewport.add() doesn't work for me - i may be because of my layout which is:
I have a viewport controller/view which is a card layout. When I click a button I have a function in the viewport controller that loads a new controller/view card in the viewport. The actionsheet is in one of these cards. The app is to big to post so hopefully it makes sense.
I have tried adding the actionsheet in my view items array but do not know how to make it show - making a reference to the xtype actionsheet doesn't return an object with a show() method it seems.
Edit: after more experiments it seems the issue is that I am placing it inside of a card - the card layout container has a relative position and the actionsheet absolute - somehow this is causing the actionsheet to go off screen. Setting card container to absolute fixes it but now I have problems with navbar positions. Suggestions?
So a bit stuck...
This is what you need to do to show your action sheet :
var actionSheet = Ext.create('Ext.ActionSheet', {
items: [
{
text: 'Delete draft',
ui : 'decline'
},
{
text: 'Save draft'
},
{
text: 'Cancel',
ui : 'confirm'
}
]
});
Ext.Viewport.add(actionSheet);
actionSheet.show();
I have an application where the UI components are added to a formField dynamically. As the UI controls to placed on screen is decided run-time depending on server response, sometime the screen gets filled with multiple components. As the screen elements are added, i required to scroll through the screen to select the fields place to the end of the screen. But when i scroll the form bounces, but the scroll is not happening the way expected. Now i am not able to select the UI controls placed to the end of the form.
The screen has 3 components, Title Bar, Button Dock bar, and a form field. Here is the code i have used for form field
var formBase = new Ext.form.FormPanel({
scroll: 'vertical',
xtype: 'form',
ui: 'round',
// i have added the items and it shows on UI, As things are dynamic i cant place it here
items: [{}];
});
Help me to fix the same.
Try this this should work.
Ext.apply(this, {
scroll: 'vertical',
pinHeaders: true,
dockedItems : [{}],
items : []
});
MyApp.views.MyScreenScreen.superclass.initComponent.call(this);
},
It happens because of the form height. Add height property to the object passed to the FormPanel. Something like this:
height: Ext.Viewport.getWindowHeight()-(the height of other compenents like toolbar)
Example for this would be:
height: Ext.Viewport.getWindowHeight()-50
Adding height config with some value might solve the issue.
I want to update the toolbar's content of the main view from a subview (HotelApp.views.hotelDetail)
This is my toolbar from HotelApp.views.mainView
this.topBar = new Ext.Toolbar({
dock:'top',
id:'main_page_topbar',
title:'H10 Sencha Demo',
items:[this.back,
{xtype: 'spacer'}
]
});
The toolbar already have a back button. The problem is i can see the shape of a button, but no text either ID. What i'm doing wrong??
I use this code:
var toolbar = HotelApp.views.mainView.getDockedItems()[1];
var images = new Ext.Button({
text:'Images',
id:'images',
ui:'drastic'
})
toolbar.setTitle(record.get('nombre'));
toolbar.add({items: images});
toolbar.doLayout();
Thanks!!!
I think that your problem is only that you have to add your button calling
toolbar.add(images);
instead of
toolbar.add({items: images});
I even suggest you to don't use 'id' config for your components but 'itemId'.
In this way you can always get your views components by calling
myView.getComponent('myComponentItemId');
or
myView.getDockedComponent('myComponentItemId');
for DockedComponents like toolbars.
Hope this helps.
I'm new with Appcelerator and I encountered an annoying problem regarding layout.
I have to do a menu bar that is very easy to do with plain html (ul>li>a and that's all). The problem is that it seems that all button-related functions are not... customizable. I want buttons to be displayed as plain text, not buttons.
The first thought was to use labels (instead of buttons). But... Is this a right way? I need a menu bar, not a text paragraph! Besides that, the menu is somehow flexible, not like labels.
This is one (of many!) things i tried:
var menu_color = Titanium.UI.createButton({
title:Ti.Locale.getString("menu_color") || "Color",
height:24,
top:10
});
I also added borderWidth:0 (no effect) and backgroundColor:none/transparent with no luck.
Help? :)
I usually use views when I need to create what you described above.
For example:
I use a view with a vertical layout, then add my child views. The child views then have listeners for the click or whatever event.
This allows you to have more control over the formatting. A side effect of this is you will need to create your own "press" ui cue in some cases.
var demo = {win : Ti.UI.currentWindow};
(function(){
//Create the container view
demo.vwMain = Ti.UI.createView({height:100, layout:'vertical', backgroundColor:'yellow'});
demo.win.add(demo.vwMain);
demo.fakebutton1 = Ti.UI.createView({height:40, backgroundColor:'blue',left:25,right:25,borderRadius:5,borderColor:'#000'});
demo.vwMain.add(demo.fakebutton1);
demo.fakebutton2 = Ti.UI.createView({top:5,height:40, backgroundColor:'green',left:25,right:25,borderRadius:5,borderColor:'#000'});
demo.vwMain.add(demo.fakebutton2);
demo.fakebutton1.addEventListener('click', function(e) {
alert('Clicked fake button 1');
});
demo.fakebutton2.addEventListener('click', function(e) {
alert('Clicked fake button 2');
});
})();
create a view with layout property is set to vertical and add label or button which you want.View is like in HTML.Hope you understand.
