The RadListView exposes some listeners on scroll events. The corresponding event data contains only the new scroll offset of the list, using dips unit.
Is there a way to get a corresponding item index in the data source for this physical position ?

In XCTest, we could find a specific UI element by index, for instance, a list view has reused item with same identifier.
app.staticTexts.matching(identifier: "BETTER").element(boundBy: 1)
So, do we have an alternative method to find an element from a list view for Android UIautomator. I found this one could get element by id, but seems it only returns the first match.
mDevice.findObject(UiSelector().resourceId("id"))
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 using boostrap library on Yii via yii-booster
I've created a relation table view
The related view is a TbGriView itself
Vhen in a row i click on the link on the 'related' column, the row expands itself, and render a TbGridview inside it.
The problem is that the internal gridview cannot be sorte, paged or filtered, because each action on it causes that the entire container grid will empty
Note
- external grid as a id of 'extenalgrid'
- each internal grid has as id like 'internalgrid-$rowId' , so every internal grid as differnt id on div, table and table row elements.
- the action called from "render related tabel" link is using renderPartial without the postProcess option. If i use potProcess, the row will be empty
So is it not possible to rendere a full working gridview/tbgridview into a related table ?
Use different css classes for the filters, buttons and headers for the different tables. From the jquery.yiigridview.js file events are bound to selectors as $('#table-id .selector-class') so elements in your internal gridView still trigger the events bound to the external gridView. You also have to specify a different url for the internal gridView by setting it's ajaxUrl.
Who knows is it possible to know which leaf item in NestedList were tapped and use this value in the Store?
May be I can use leafitemtap not only in listeners of NestedList?
According to this:
http://docs.sencha.com/touch/2-0/#!/api/Ext.dataview.NestedList-event-leafitemtap
the leafitemtap listener function gives you the following params:
leafitemtap( Ext.dataview.NestedList this, Ext.List list, Number index, Ext.dom.Element target, Ext.data.Record record, Ext.event.Event e, Object eOpts )
in which:
this points to your current nested list
index is the index of tapped item
target is the DOM element of tapped item
record is the model object of tapped item
Suppose that your model has an id field. Then:
record.get('id') will return the id of tapped item. You can use this to look it up later in your Store.
I'm using Dojo.dnd to transfer items between to areas. The problem is: the items will snap into place once I drop them, but I'd like to have them stay where I drop them, but only for one area.
Here's a little code to explain this better:
<div id="dropZone" class="dropZone">
<div id="itemNodes"></div>
<div id="targetZone" dojoType="dojo.dnd.Source"></div>
</div>
"dropZone" is a DIV that contains two dojo.dnd.Source-areas, "itemNodes" (created programmatically) and "targetZone". Items (DIVs with images) should be dragged from a simple list out of "itemNodes" into "targetZone" and stay where they are dropped. As soon as they are dragged out of "targetZone" they should snap back to the list inside "itemNodes".
Here's the code I use to create the items:
var nodelist = new dojo.dnd.Source("itemNodes");
{Smarty-Loop}
nodelist.insertNodes(false, ['<img class="dragItem" src="{$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.
