Carouselview: If only one item in view, items is shown indefinatley - xaml

So a carouselview is awesome for showing multiple elements. But once ther eis only one element in the view and the element isnt as large as the whole screen is, the result is:
Result
So I would need to make sure that if only one element is inside the view, it isnt repeated.
How can I set this or work around this issue without making two layouts and making only one visible, depending on how many items there are in the view?

Its quite simple. If the list contains only 1 item, just set the peek area to 0, otherwise to whatever value you wanT:
if (contentOfListView.Count == 1)
carousel_myAds.PeekAreaInsets = 0;
else if (contentOfListView.Count == 2)
carousel_mySales.PeekAreaInsets = Constants.PEEKAREINSETSHALF;
else
carousel_myAds.PeekAreaInsets = Constants.PEEKAREINSETS;

composeTestRule checking that atleast 1 item exists

I have a list which has 2 different items. However, if the user gets close to the end of the list then the 2 same items are added again and again to create an infinite scrolling feel.
I've created a test to basically verify that the item exists like so:
composeTestRule
.onAllNodesWithContentDescription("Home")
.assertCountEquals(2)
As you can see this just finds nodes with the content description of "Home" and checks if their are 2.
Currently, this works as the screen size is small but let's say the screen size is doubled then this will fail as the assertCountEquals(2) would need to check for 4.
I was wondering to make this code better, is there a way to basically check that atleast 1 exists?
onAllNodes methods return an array, grab the first element and check whether it exists or is displayed.
composeTestRule
.onAllNodesWithContentDescription("Home")
.onFirst().assertExists()

XPath selector returns empty list

I'm trying to scrape data from store: https://www.tibia.com/charactertrade/?subtopic=currentcharactertrades&page=details&auctionid=12140&source=overview
There is no problem with getting data from 1st and 2nd table, but when I goes down, xpath returns only empty lists.
even tried to save response in file:
scrapy fetch --nolog "https://www.tibia.com/charactertrade/?subtopic=currentcharactertrades&page=details&auctionid=3475&source=overview" > response.html
for table with skills everything works good
sword = response.xpath('//div [#class="AuctionHeader"]/a/text()').get()
but when it comes to getting for example gold value, I get only empty list:
gold = response.xpath('/html/body/div[3]/div[1]/div[2]/div/div[2]/div/div[1]/div[2]/div[5]/div/div/div[3]/div[2]/div[2]/table/tbody/tr/td/div/table/tbody/tr[2]/td/div[2]/div/table/tbody/tr[3]/td/div/text()').get()
In chrome/firefox both selectors works smooth, but in scrapy only 1st one
I know there might be some problems with data updated by javascript, but it doesn't look like this case
Doesn't look like it's a javascript problem. Think you're not getting your XPATH selectors correct. It's best to be as specific as possible and not to use multiple nodes down. Here we can select the attribute TableContent to get the tables you want. There you can select each individual table that you require if needed.
Code Example
table = response.xpath('//table[#class="TableContent"]')[3]
gold_title = table.xpath('tr/td/span/text()')[2].get()
gold_value = table.xpath('tr/td/div/text()')[2].get()
output
'Gold: '
'31,030'
Explanation
Using the class attribute TableContent, you can select which table you want. Here I've selected the table with the gold values. I've then selected each row and the specific element which has the gold value. The values are hidden behind span and div elements. get() returns a string, getall() returns a list.

Deselect v-list-item when changing its value

I have a v-list-item-group with some v-list-item's inside with an associated value. The problem is that when I change the value of the selected v-list-item it doesn't react. I want it to be selected only when the new value matches the v-list-item-group's model and be unselected otherwise. What is the best way to achieve such a behaviour?
Example. When you edit the list item value, for example, by changing the lower left field from "Bluetooth" to "Bluetooth1", I want the list item to get deselected automatically because its value isn't longer matching v-list-item-group's model ("Bluetooth1" != "Bluetooth"). And when you change it back to "Bluetooth" I want it to get selected again.
The one on the right modifies the v-list-item-group's model and this works as expected.
My actual use case is rendering lists of thousands of elements quickly without rendering them all. To achieve it I use a recycle-scroller component inside my v-list-item-group to manage its items. It creates a few dozens of v-list-items and as user scrolls it reuses them by moving them around and replacing their value, icon and text with corresponding data from my array. The problem is that when user selects some list item then scrolls the list, the selected item gets reused. Despite the fact that it now has a different value, text and icon it still looks as selected. So they see it as if some different item was selected.
I hope this works for you:
<v-list-item-group v-model="model" :color="color">
// other html
Then add a computed property:
computed: {
color(){
if (this.model == this.items[1].text) {
return 'indigo'
} else {
return 'black'
}
}
}

'First in' in Sencha Touch adding items to the container

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.

Use Dojo Drag and Drop together with Dojo Moveable

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.
