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();

If you look at the bootstrap demo that is hosted here And scroll down to the demo that has all 4 buttons. Now click on the left popover, it shows properly. However, When I shrink or extend the screen the popover is no longer anchored to the proper point. Is there a way around this?
This has to do with the container property for the popover.
http://jsfiddle.net/yvkhbw4b/1/
See the attached example. Show both popovers then resize the window from xs breakpoint to sm breakpoint. You will see the top item will seperate from the button as the container defaults to body. (I'm also setting it to body though options). The second item is attached to the parent div so that one remains attached to the element even though the breakpoint changed.
Documentation on popover options
Appends the popover to a specific element. Example: container: 'body'.
This option is particularly useful in that it allows you to position
the popover in the flow of the document near the triggering element -
which will prevent the popover from floating away from the triggering
element during a window resize.
$('#btn1').popover({
'container': 'body'
});
$('#btn2').popover({
'container': '.col-sm-12'
});
Potential Fix: you could add the following code. Currently only handles bottom aligned popovers but you can add options for other alignments.
$(window).resize(function () {
$('.popover.in').each(function () {
var el = $('[aria-describedby="' + this.id + '"]');
if ($(this).hasClass('bottom')){
$(this).css('top',el.offset().top + el.outerHeight(true));
}
});
});

I came across a situation in sencha touch where i need to change from one view to another on click of a button .
My view 1 is a dashboard which displays around 8 icons and on click of each icon different views are shown . So, i placed an home button in the header of those 8 different views and i am trying to get back to the dashboard which is not hapenning .Instead it is showing a blank screen and there was no error displayed in the console for me to check .
My code for changing the view on button click was :
{
xtype:'button',
cls:'clsHome',
text:'Home',
style: 'background:#4A4245;color:white;',
handler: function() {
console.log("Home Clicked");
var dashboardPanel = Ext.create('AppSupport.view.DashBoard');
Ext.Viewport.add(dashboardPanel);
//Ext.Viewport.setActiveItem(dashboardPanel,{type: 'slide', direction: 'left'});
}
}
Help me Guys ... Thanks in Advance ...!!!
You should try the Using Navigation View tutorial in sencha architect documentation... It gives a simple step by step guide for view navigation for an app. The navigation view also provides in built history support from sencha touch 2 onwards which also makes going back simple and easy
http://docs.sencha.com/architect/2/#!/guide/navigationview
I'm using a navigation.View to hold a list, so I can easily implement a detail view which appears when someone clicks on an item. I also have a search bar docked at the top of this list view, but what I'd like to do is hide this by default and have a button within the titlebar which would allow the user to show/hide the search bar.
I've tried using the following code to achieve this:
navigationBar: {
items: [{
xtype: 'button',
align: 'right',
text: 'Search'
}]
}
but this causes the button to display on every page I push into the navigation view, whereas I want the button to only appear on the root list page. Is this even possible?
Any help is appreciated.
In this case, you had better not use Ext.NavigationView. Just use normal views which toolbars.
But if you still want to use navigation view, here maybe a hint to start with:
Add that button to your navigation bar and set config hidden: true by default.
Listen for an event which can observe when your active view is changed. This may vary depending on your app structure.
When your "special" view is activated, show that button to the navigation bar, and when it is deactivated, hide that button.
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.
