Can I add an item to the container as the first one rather than appending all existing ones.
From what I understand this.add([item]) will add item as the last one, however I would like it to apper it on the top of the screen before anything else has been added.
You can use insert method of container like this:
this.insert(0 , item);
where it would appear depends on your layout.

Is there a way to have the categories sidebar menu start in the expanded state? Currently it starts out collapsed and requires the user to expand the top level categories to view the ones underneath.
My store has only one main category right now and I would like to have it expanded unless the user chooses to collapse it
here is a link to the demo page as my site has not been published yet.

Since the category list is controlled by a snippet, you would need to use javascript to autoselect/autoexpand that particular parent category.
Something like:
$(document).ready(function(){
if ($('li:contains(parentCategoryName)').hasClass('expandable') {
$(this).addClass('collapsable');
$(this).removeClass('expandable');
}
else {
return null;
}
});
I haven't tested the above script, but that would be one of my first tries. It may require tweaks. You should replace "parentCategoryName" with the name of your parent category that you want to expand.
I have a scrollableView with several views inside and I'd like to add item to some of these view if they meet a certain criteria, like if they have data attached or not. Also I'm using Alloy, here's my markup
<ScrollableView id="scrollableView">
<View id="view" class='coolView'></View>
...
</ScrollableView>
To know if there are data attached I check the currentPage attribute like so:
function updateCurrentView(e) {
currentView = e.currentPage;
}
But I have no idea how to add an item to the current View.
Edit: To add some clarification, I have a label which when clicked allow me to choose two currencies, when chosen these currency pairs are saved in the database and should be displayed instead of the label. So my guess was to check whether the current view has currency pair saved.
There are 2 things to take care of here:
1.Whenever a currency is selected,immediately label on that particular view will change.
2.Whenever the scrollableView is loaded,it must always refer to the database if a currency is selected.
First one can be done as:
1.Get the instance of scrollableView using the getView method of alloy controller.Pass the id of the scrollableView to it.Lets call it myScrollableView.Refer this for more info.
http://docs.appcelerator.com/titanium/latest/#!/api/Alloy.Controller
2.Use var currentView=myScrollableView.getCurrentPage() to the get the current page which will be a number.
3.Now use the scrollableView instance to get all the views.
var viewArray=myScrollableView.getViews();
4.viewArray[currentView] will give you the view of current page.After you have got the view you can change the desired label using:
viewArray[currentView].children[positionOfTheView]
The "positionOfTheView" can be obtained by printing the viewArray[i].children array using Ti.API.info.
Second thing can be accomplished as follows:
1.Get the instance of scrollableView using the getView method of alloy controller.Pass the id of the scrollableView to it.Lets call it myScrollableView.Refer this for more info.
http://docs.appcelerator.com/titanium/latest/#!/api/Alloy.Controller
2.Now use the scrollableView instance to get all the views.
var viewArray=myScrollableView.getViews();
3.This is a JavaScript array of all the views in the scrollableView. Now iterate through this array and according to the data in the database,change the concerned view using:
viewArray[i].children[positionOfTheView]
The "positionOfTheView" can be obtained by printing the viewArray[i].children array using Ti.API.info.
I'm on ExtJS 4 and using an MVC approach. I've created a simple grid view class, and have added a componentquery type 'ref' to that view in my controller. Within the initial grid view itself I set several columns to be hidden and some to be visible by default. The rendering of the grid with those settings is all working fine.
Then I have a button that, when clicked and based on some other conditions, will make some of the initially hidden grid columns visible. This works as well.
But what I need is a way to later 'reset' the grid to its initial view (with the correct columns hidden/visible, as they were initially).
I've tried various permutations of the following with no effect:
var theGrid = this.getTheGrid();
theGrid.reconfigure(store, theGrid.initialConfig.columns);
theGrid.getView().refresh();
I suppose I could loop through every column and reset its 'hidden' state, but would think there's a way to just 'reset' back to what's set in the class? Advice?
SOLUTION UPDATE
Appreciate the pointer from tuespetre. For anyone coming along in the future looking for specifics, here is what was needed (at least for my implementation):
Within the view, moved the column defs into a variable
Within the view, columns ref within the class becomes:
columns: myColumns,
Within the view, the following function created within the class:
resetGrid: function(){
this.reconfigure(null, myColumns);
},
Within the controller:
var theGrid = this.getTheGrid();
theGrid.resetGrid();
You will just need to create a function on your view class to encapsulate that functionality.
I have a requirement to create a xaml page with Semantic Zoom where the zoomed in view contains both GridViews and ListViews. I have started out with the basic Grid Application template.
In order to try to achieve this, I have made the Semantic Zoom control's zoomed in view show a list view, and the list view contains the ListView and GridView controls I need to actually show the data as ListViewItems. This works, up to a point - the issue is that the mouse-down or tap animations happen on the whole child control of the parent ListView instead of the child's elements. This sort of layout would be simple if I didn't need to support semantic zoom.
So, my question is is this the best way to achieve this sort of layout, or am I missing something. If this is the best way, is it possible to control the behaviour so that the child item elements have the correct animation effect on selection?
Additional Info
The choice of GridView or ListView is based on the type of the items in the collections. In this example, grp 1, 3 and 4 (to be shown in grids) are all collections of type NewsFull and the remainder (to show in Lists) are of type HeadlineOnly, both types inherit from NewsBase.
The page layout (zoomed in) should be something like this...
Title
grp 1 grp 2 grp 3 grp 4 grp 5
[g][g][g][g] [_list item_] [g][g][g][g][g] [g][g][g] [_list_item_]
[g][g][g][g] [_list item_] [g][g][g][g][g] [g][g][g] [_list_item_]
[g][g][g][g] [_list item_] [g][g][g][g] [g][g] [_list_item_]
[g][g][g] [_list item_] [g][g][g][g] [g][g]
where [g] is a grid view item, and [_list_item_] is a list view item.
Zoomd out view is like this...
Title
grp 1 grp 2 grp 3 grp 4 grp 5
[summary] [summary] [summary] [summary] [summary]
Perhaps you can try using the ItemContainerStyleSelector to swap out the container of the items based on the item type or similar? This way, may be you can set one group to have a wrapping layout container and another can just be a stackpanel?
the design looks reasonable to me. the issue you have is merely " is it possible to control the behaviour so that the child item elements have the correct animation effect on selection?"
the problem here is that you probably lack abstraction here regarding different levels of UI object. I would assume you wrote this big control simply using one xaml object and then messed up with the style setup. In my opinion, you will need to break your UI to these levels of components:
ZoomPage // which is essentially a list
GroupElement // which could be GRID object or list object depending on the DATACONTEXT
GroupElement // which also has a summary state.
what you specified definitely can be achieved, looks to me just the styles are not deployed properly, if indeed your control is too complex, break it down, and test them separately.
hope this helps
I'm using Dojo.dnd to transfer items between to areas. The problem is: the items will snap into place once I drop them, but I'd like to have them stay where I drop them, but only for one area.
Here's a little code to explain this better:
<div id="dropZone" class="dropZone">
<div id="itemNodes"></div>
<div id="targetZone" dojoType="dojo.dnd.Source"></div>
</div>
"dropZone" is a DIV that contains two dojo.dnd.Source-areas, "itemNodes" (created programmatically) and "targetZone". Items (DIVs with images) should be dragged from a simple list out of "itemNodes" into "targetZone" and stay where they are dropped. As soon as they are dragged out of "targetZone" they should snap back to the list inside "itemNodes".
Here's the code I use to create the items:
var nodelist = new dojo.dnd.Source("itemNodes");
{Smarty-Loop}
nodelist.insertNodes(false, ['<img class="dragItem" src="{$items->info.itemtext}" alt="{$items->info.itemtext}" border="0" />']);
{/Smarty-Loop}
But this way I just have two lists of items, the items dropped into "targetZone" won't stay where I dropped them. I've tried a loop dojo.query(".dojoDndItem").forEach(function(node) to grab all items and change them to a "moveable"-type:
using dojo.dnd.move.constrainedMoveable will change the items so they can always be moved around (even in "itemNodes")
using dojo.dnd.move.boxConstrainedMoveable and defining the "box" to the borders of "targetZone" makes it possible to just move the items around inside "targetZone", but as soon as I drop them, I can't grab and move them back out. (Strange: dojo.connect(node, "onMoved" doesn't work here, the even won't fire, no matter what.)
So here's the question: is it possible to create two dnd.Sources where I can move items back and forth and let the items be "moveable" only in one of the sources?Or is there a workaround like making the items moveable and if they're not dropped into "targetZone" they'll be moved back to the list in "itemNodes" automatically?
Once the page is submitted, I have to save the position of every item that has been placed into "targetZone". (The next step will be positioning the items inside "targetZone" on page load if the grid has already been filled before, but I'd be happy to just get the thing working in the first place.)
Any hint is appreciated.
Greetings, Select0r
There is no direct support for such features. It can be done with a custom code, e.g., by subclassing a Source and overriding its insertNodes().
Here's a quick workaround to get this working:
I ended up using only one DIV which is a dojo.dnd.Source and contains the items that should be dropped into a "dropZone" and moved around in it while snapping back to the item-list when placed outside the dropZone.
All items are a dojo.dnd.move.parentConstrainedMoveable to make them movable in the originating DIV. Connecting to onMoveStop will give me the opportunity to decide whether the "drop" has occured in the dropZone or somewhere else.
if (coordX >= (dropCoords.l + dropAreaX) &&
coordX <= (dropCoords.l + dropAreaX + dropAreaW) &&
coordY >= (dropCoords.t + dropAreaY) &&
coordY <= (dropCoords.t + dropAreaY + dropAreaH))
{
// OK!
}
else
{
// outside, snap back to list
}
dropAreaX and dropAreaY contain the coordinates where the dropZone starts, dropAreaW and dropAreaH contain its width and height.
If "OK!", the items will be saved into an array, so I know which items have been dropped. Otherwise the item will be removed from that array (if it's in there) and the item will be placed back into the list (via CSS "left: 0"). The number of elements in the array will tell me how many elements are left in the list, so I can "stack" them in a loop using "top: numberOfElement * heightOfElement px").
There's more to it as I need the items coordinates written to hidden fields, but I guess this should get anybody who's working on a similar problem on the right track.
