I'm modifying the DOM Traversal example that comes with Qt. However, whenever I see a link, I want to "go" to that URL and also traverse its DOM, but I don't want to reload the GUI. Right now I'm still using the code from the example to get the homepage:
void Window::on_webView_loadFinished()
{
treeWidget->clear();
QWebFrame *frame = webView->page()->mainFrame();
QWebElement document = frame->documentElement();
examineChildElements(document, treeWidget->invisibleRootItem());
}
This works great. In examineChildElements(), when I encounter a specific link, I then call another function with the URL (I checked the URL string; it's correct):
void Window::parse_page(QString page_URL)
{
QWebView *innerPage = new QWebView();
innerPage->setUrl(page_URL);
QWebFrame *frameInner = innerPage->page()->mainFrame();
QWebElement documentBetrieb = frameInner->documentElement();
get_biz_info(documentBetrieb);
delete innerPage;
return;
}
But when I traverse this document (documentBetrieb), there is only an HTML tag. Is there a step I'm missing, or a way of putting the DOM from a URL directly into a QWebElement without using QWebView?
Are you sure setUrl() is loading the URL synchronously? I suppose you need listen to QWebView::loadFinished(bool ok) signal before accessing the DOM.

I created a CopyToMarkets.XML dialog file based off of the \Dialogs\CopyTo.XML file:
And attempting to open the dialog with:
Context.ClientPage.ClientResponse.ShowModalDialog("/sitecore/shell/Applications/Dialogs/Copy To Markets.aspx", "1200px", "700px", string.Empty, true);
It just turns grey and nothing happens.
However when I use ShowModalDialog with Copy To.aspx it shows up fine.
I'm new to sitecore so maybe I'm misunderstanding something but basing my understand of creating content editor ui form this tutorial: https://sitecorejunkie.com/2012/12/12/put-things-into-context-augmenting-the-item-context-menu-part-2/
Let me know if this isn't the correct/modern method of creating new editor dialogs!
I ended up building my url like this:
string url = Sitecore.UIUtil.GetUri("control:CopyToMarkets");
Context.ClientPage.ClientResponse.ShowModalDialog(url, "400px", "700px", string.Empty, true);
Update 2:
I am still fighting to get the Icon save on the server.
Here what I am doing:
Item item = Sitecore.Context.Database.GetItem(imageId);
var imageIconUrl = Sitecore.Resources.Images.GetThemedImageSource(item.Appearance.Icon, ImageDimension.id32x32);
if (!string.IsNullOrEmpty(imageIconUrl))
{
// download the icon from the url
var iconFullPath = "e:\\pngIcons\\excelIcon.png";
var webClient = new System.Net.WebClient();
var downloadPath = "http://serverName/" + imageIconUrl;
webClient.DownloadFile(downloadPath, iconFullPath);
}
The variable downloadPath contains following string:
http://serverName/sitecore/shell/themes/standard/~/media/E503BA48C89B422D8400393F1C7086A7.ashx?h=32&thn=1&w=32&db=master
At the end what I can see is a png file but there is nothing in it. I also copy the string I get in variable downloadPath and pasted it in browser and I can see the Icon as follow:
Please let me know what I am doing wrong. Or How I can save the Icon. Thanks!!
Original Question:
The sitecore media item has a field "Media". I am talking about this:
I want to access this field. And the reason is:
If I access it with e.g. item.GetMediaStream() then I will get the complete file. I just want to save this little icon some how on the server. Is it possible ?
To get the icon/thumbnail you can use
var icon = Sitecore.Resources.Media.MediaManager.GetThumbnailUrl(mediaItem);
To get the url of the thumbnail.
If you want the stream of the thumbnail you need to use the MediaData object. Like this:
var mediaItem = new MediaItem(item)
var mediaData = new MediaData(mediaItem);
var iconStream = mediaData.GetThumbnailStream();
if (iconStream.Length < 0)
{
// The stream is empty, its probably a file that Sitecore can't
// generate a thumbnail for. Just use the Icon
var icon = item.Appearance.Icon;
}
This will get the icon or thumbnail of the actual media blob that is attached to the media item. If you just want the icon of the Sitecore item, then use Martins method.
If the stream is empty, then Sitecore can't generate a thumbnail for it, so you can just use the icon file for the media item template. item.Appearance.Icon
Appearance section (of Standard Template) has a field called Icon - this is where you can modify icon for the item. There is also a field called Thumbnail - your excel icon is sitting there
You can access the field programmatically, just mind that it starts with two underscores: __Icon:
var iconField = item.Fields["__Icon"];
var thumbnailField = item.Fields["__Thumbnail"];
Update: As you asked, below is the code that saves either of fields into the file on a drive. I have tested the code and confirm successfully stores icon from thumbnail field into the file:
string mediaItemPath = "/sitecore/media library/Files/ExcelFile";
string mediaFiedlName = "Thumbnail"; // also can be "__Icon"
var item = Sitecore.Context.Database.GetItem(mediaItemPath);
var iconField = item.Fields[mediaFiedlName];
if (iconField.HasBlobStream)
{
var thumb = (ImageField)iconField;
var bl = ((MediaItem)thumb.MediaItem).InnerItem.Fields["blob"];
Stream stream = bl.GetBlobStream();
byte[] buffer = new byte[8192];
using (FileStream fs = File.Create("D:\\you_file_name.ico")) // change your path
{
int length;
do
{
length = stream.Read(buffer, 0, buffer.Length);
fs.Write(buffer, 0, length);
}
while (length > 0);
fs.Flush();
fs.Close();
}
}
Update 2: If that does not help then I would advise to look around the way how that icon gets generated on Media field in Sitecore. In the worst case you may do the following - right click that icon and see its url. You will have something similar to what I assign to variable below:
string url = "http://test81/sitecore/shell/Applications/-/media/B4F61650CBE84EE396649602C0C48E1B.ashx?bc=White&db=master&h=128&la=en&mw=640&thn=1&vs=1&ts=b8046903-ae57-4f9d-9dd5-b626ee5eee90";
Of course your URL should have your hostname and media prefix and the rest of parameters. Then use Webclient with that modified URL:
WebClient webClient = new WebClient();
webClient.DownloadFile(url, "e:\\you_file_name.ico");
Not ideal, but may work. Note, that the code above should work in a context of already logged user, so you need to authorise you Webclient prior that (many articles on S.O. how to do that).
Please reply if that approach has worked for you (I've spent decent time writing and testing that code in debugger, so would want to know whether that helped)
I'm using polymer 1.0.
I'm trying to open a with on a clic on an element created dynamically with template repeat.
Here is the code :
<paper-button
data-dialog="modal"
on-click="dialogClick">
Click
</paper-button>
and the script (from doc) :
dialogClick: function(e) {
var button = e.target;
while (!button.hasAttribute('data-dialog') && button !== document.body) {
button = button.parentElement;
}
if (!button.hasAttribute('data-dialog')) {
return;
}
var id = button.getAttribute('data-dialog');
var dialog = document.getElementById(id);
alert(dialog);
if (dialog) {
dialog.open();
}
}
This work only if the value of data-dialog is simple text. If I want to change it by data-dialog="{{item.dialogName}}" for instance, it doesn't work. It is not found by the while loop and exit with the if. in the source code of the page, there is no data-dialog in the paper-button.
Any idea ?
I've ran into a similar problem when using data attributes on custom elements. You might want to subscribe to this polymer issue.
As a workaround, place the data attribute in a standard element that is a parent of the button and search for that one instead.
Also, you might want to consider using var button = Polymer.dom(e).localTarget instead of directly accessing e.target, since the later will give you an element deeper in the dom tree under shady dom.
I am trying to display a web page using the below code
QWebView *view = new QWebView();
view->load(QUrl("qrc://images//sample page.html/"));
view->show();
sample page.html is added to project resources/Images. The web page frame is loading, but I can't see any html data.
I tested with the below web url and it loaded the page
view->load(QUrl("http://www.google.com/"));
You will have to go through a few steps as follows:
1) Get the QWebPage object:
QWebPage *page = view->page();
2) Get the QWebFrame object:
QWebFrame *frame = page->currentFrame();
3) Call the toHtml member function on the current frame:
QString html = frame->toHtml();
Of course, you will need to add appropriate error checks in between.
I have an application that is creating an new item in Sitecore then opening up the Content Editor to that item, it is loading fine but whenever i try to open the html editor i get a 'NullReferenceException'. This is only happening when i launch the application in this method.
Source Code:
[Serializable]
public class PushToCMS : Command
{
public override void Execute(CommandContext context)
{
//Context.ClientPage.Start(this, "Action_PushToCMS");
Database dbCore = Sitecore.Configuration.Factory.GetDatabase("core");
Item contentEditor = dbCore.GetItem(new ID("{7EADA46B-11E2-4EC1-8C44-BE75784FF105}"));
Database dbMaster = Sitecore.Configuration.Factory.GetDatabase("master");
DatabaseEngines engine = new DatabaseEngines(dbMaster);
Item parentItem = dbMaster.GetItem("/sitecore/content/Home/Events/Parent/");
// Load existing related item if it exists
Event evt = new Event(new Guid(HttpContext.Current.Items["id"].ToString()));
Item item = dbMaster.SelectSingleItem("/sitecore/content/Home/Events/Parent/Item");
if (item == null)
item = CreateNewEvent(engine.DataEngine, parentItem, evt);
Sitecore.Text.UrlString parameters = new Sitecore.Text.UrlString();
parameters.Add("id", item.ID.ToString());
parameters.Add("fo", item.ID.ToString());
Sitecore.Shell.Framework.Windows.RunApplication(contentEditor, contentEditor.Appearance.Icon, contentEditor.DisplayName, parameters.ToString());
}
The only difference i can tell in the loading of the two methods is the url to the html editor, however i dont know where this is being defined or how i can control it.

any help on this would be greatly appreciated.
Phil,
If it is not too late for the answer... :)
It might be the case that you run this code without the permissions to read the core database. In this case, when you try to call contentEditor. you'll get NullReference. I would recommend you using another format of running the application - use another method:
Sitecore.Shell.Framework.Windows.RunApplication("Content Editor", parameters.ToString());
If this doesn't help, please attach the stack trace of the exception you get.
Hope this helps.
