I am new to EXTJS. I am working on migrating the existing extjs3 code to extjs4.
How can I replace the code in order to work in extjs4?
var cm = this.grid.getColumnModel();
cm is being used as below:
cm.getColumnCount();
var c = cm.getColumnAt(i);
Thanks in advance!
Rahul
var columns = this.grid.getView().getHeaderCt().getGridColumns();
That will return an array of all the columns in the grid. You can then replicate the actions you listed above:
// replaces cm.getColumnCount();
columns.length;
// replaces var c = cm.getColumnAt(i);
var c = columns[i];

For reference I'm using the Serenity application template.
I have the following code
var query = new SqlQuery();
query.From("TenantData")
.Select("ItemData")
.Select("ItemType")
.Where(new Criteria("TenantID") == userDefinition.TenantId);
using (var connection = sqlConnections.NewByKey("Default"))
{
var data = connection.Query(query);
}
The data returned looks like {{DapperRow, ItemData = '2342342wef', ItemType = 'test'}}
What I'm struggling with is how to convert this into a dictionary (ItemData being the key, ItemType being the value).
I've tried a select but it doesn't seem to be supported so I'm at a bit of a loss.
The following should work.
var data = connection.Query(query);
var d = data.ToDictionary(row => (string)row.itemdata, row => (string)row.itemtype);
Make sure you add the using System.Linq; at the top. ToDictionary() is an extension method.
I'm trying to create a purely JXA-ObjC approach to getting pixel colors from image paths. Here's what I have currently:
ObjC.import('Foundation')
ObjC.import('AppKit')
var c_filePath = $(picturePath)
var c_img = $.NSImage.alloc.initWithContentsOfFile(c_filePath)
if(c_img==$()){
return []
}
var c_point = $.NSMakePoint(x,y)
c_img.lockFocus() //Error - Undefined is not a function...?
var c_color = NSReadPixel(c_point)
c_img.unlockFocus() //Error - Undefined is not a function...?
c_img.release()
var r; var g; var b; var a
c_img.getRegGreenBlueAlpha($(r),$(g),$(b),$(a))
r = ObjC.unwrap(r)
g = ObjC.unwrap(g)
b = ObjC.unwrap(b)
a = ObjC.unwrap(a)
This code is heavily based off of the code found here.
However, as shown above c_img.lockFocus() is undefined according to JXA. Oddly I can get access to c_img.lockFocusFlipped(), however I'm not sure how to use this and/or if it can be used for the same purpose as lockFocus().
Is there an obvious problem here? Or is there a better way to get the pixel colour of an image?
Any help would be grateful.
It looks like I am too used to methods requiring parenthesis. TylerGaw however told me that this is not necessarily the case.
ObjC.import('Foundation')
ObjC.import('AppKit')
var c_filePath = $(picturePath)
var c_img = $.NSImage.alloc.initWithContentsOfFile(c_filePath)
if(c_img==$()){
return []
}
var c_point = $.NSMakePoint(x,y)
c_img.lockFocus
var c_color = NSReadPixel(c_point)
c_img.unlockFocus
c_img.release
appears to work as expected.
jsonStoreInit = function(pSuccess, pFailure){
collections={};
collections['objects'] = {};
var options = {};
options.localKeyGen = false;
options.clear = false;
options.username = app.username;
options.password = app.password;
options.additionalSearchFields = {key: 'string'};
WL.JSONStore.init(collections, options)
.then(pSuccess)
.fail(pFailure);
};
putObject = function(pObject) {
var keyValue = pObject.getKey();
var object = {myObject : pObject.getKey()};
var options = {};
//options.additionalSearchFields = {key : keyValue};
WL.JSONStore.get("objects")
.add(object, options);
};
I'm on WL 6.0 FP 1
In the code sample above jsonStoreInit is what I use to init my store including the options.additionalSearchFields.
When I come to add the objects in the putObject funciton it works fine with the additionalSearchFields commented out, but when I uncomment it to add the additional fields I get an error
[wl.jsonstore] {"src":"store","err":21,"msg":"INVALID_ADD_INDEX_KEY","col":"objects","usr":"xxxx","doc":{},"res":{}}
When I look this error message up all I get is
21 INVALID_ADD_INDEX_KEY
Problem with additional search fields.
Which I had kinda figured ... can anyone provide any help on this ...
I don't need to you fix my code but if you could point me to a working example that would be excellent.
Many thanks, ownimage
The person that asked the question solved it, but I'm leaving this answer in case someone is wondering how to pass data that uses additionalSearchFields.
Example:
var data = {hello: 'world'};
WL.JSONStore.get('collection').add(data, {additionalSearchFields: {key: 'value'}})
The example assumes the collection was created with a search field for hello as string and an additional search field for key as string. It also assumes there's a collection initialized called collection.
I'm using a Dojo Data grid together with a REST service to display view data. When I double click on a row, an XPage is opened. My problem is that, if one of the columns in the grid is not sorted, the wrong XPage is opened. What could be the problem here?
<xe:djxDataGrid id="P_Alle_DDG" store="restService2"
styleClass="DojoViewTable" title="Pendenzen - Alle" autoHeight="20"
rowsPerPage="25" selectable="true" selectionMode="multiple"
singleClickEdit="true" rowSelector="2" style="font-size:12pt"
escapeHTMLInData="true">
<xe:this.onRowDblClick><![CDATA[var idx = arguments[0].rowIndex;
var unid = restService2._items[idx].attributes["#unid"];
var url = 'Reparatur.xsp?documentId='+unid+'&action=openDocument';
window.document.location.href = url;]]></xe:this.onRowDblClick>
UPDATE: With the following JavaScript code the problem has been solved:
var grid = arguments[0].grid;
var index = arguments[0].rowIndex;
var item = grid.getItem(index);
var unid = item.attributes["#unid"];
var url = 'Reparatur.xsp?documentId='+unid+'&action=openDocument';
window.document.location.href = url;
Tony, try this method of opening the document. The code if very similar to yours, but the key difference is that I made a view column that contains the unid, I called it "docid". This works for me.
var grid = arguments[0].grid;
var index = arguments[0].rowIndex;
var item = grid.getItem(index);
var unid = item["docid"];
var url = "New_PO.xsp?doc=" + unid;
window.document.location.href = url;
I am creating a custom module in Orchard. After I enable my module I would like to create a query programmatically.
I do that in my Migrations.cs file thanks to implementation of IDependency interface.
I am able to create the query but I do I programmatically set filters of that query?
var announcementsQuery = _contentManager.Create("Query");
announcementsQuery.As<TitlePart>().Title = "Announcements";
_contentManager.Publish(announcementsQuery);
I found out how to do this:
var announcementsQuery = _contentManager.Create("Query");
announcementsQuery.As<TitlePart>().Title = "Announcements";
announcementsQuery.As<QueryPart>().ContentItem.ContentType = "Announcement";
var filterGroupRecord = new FilterGroupRecord();
var filterRecord = new FilterRecord()
{
Category = "Content",
Type = "ContentTypes",
Description = "Announcement",
Position = 1,
State = "<Form><Description>Announcement</Description><ContentTypes>Announcement</ContentTypes></Form>"
};
filterGroupRecord.Filters.Insert(0, filterRecord);
announcementsQuery.As<QueryPart>().FilterGroups.Insert(0, filterGroupRecord);
