Hello,
at the moment I am evaluating the TIWCGJQTreeView component
and I wonder if and how it is possible to set the href-value of the TreeNodes.
At the moment it seems that the component sets it to a standard value:
href="http://127.0.0.1:8888/#"

Kind regards

Hi itroeger,

Hello,

According to the author of the plugin, you can't set "href" to the node.

What are you trying to do?

Best Regards.

Hello,

I want to build a kind of filetree to list
files and folders of a WebDAV-Server. When a user clicks onto
a TreeNode the filelink should be executed to show the file in
MS Word for example. Therefore I need different URLs for every TreeNode.

It seems to be possible to insert an additional href-entry (by using the Caption property)
but that has the side effect that the image of the treeview is shown twice.

Kind regards,

Hi itroeger,

We have implemented a new property "UserAttributes" in tree node, which allow to storage the user data in html.
Will be released asap.

Just for information, If you have some knowledge of javascript, you can use the property "Script" in each event, for instance OnSelect.Script.

Example to open the link by javascript:

Code: Select all

 window.location.url = 'http://www.cgdevtools.com';


or open in new window:

Code: Select all

 window.open('http://www.cgdevtools.com');


*EDITED: Available from V1.6.0.2618

Best Regards.

Hello cgdevtools,

with the new property UserAttributes it is not possible to insert a
href attribute. I just get the error message that

you can not use reserved word href

Kind regards,

Hi itroeger,

Yes, you can't use these attribute as custom.
If you want add and them get your custom attr, you should do something like this:

1.
delphi code

Attribute:= 'myhref'
Value:= 'http://www.cgdevtools.com/';

2. Add browser param to event

delphi code

with JQTV1.JQEvents.OnSelect do
begin
   with BrowserParams.Add do
     begin
       BrowserScript:= JQTV1.JQTreeViewOptions.UIPlugin.jsGetSelected + '.attr("myhref")';
       ServerName:= 'HrefValue';
   end;
end;

3. Get your user data

delphi code

var
  LMyHref: string;
Begin
  LMyHref:= AParam.Values['HrefValue'];
end;

Best Regards.

Hi cgdevtools,

I have tried to implement your tips but the value which is returned
for the attribute myhref is "undefined". Is there something I am doing wrong?

Kind regards

Code: Select all

procedure TIWFrameTreeView.ProcessCommand(ACommand: Integer; AParams: TStrings = nil);
var
  aCGUserAttribute: TCGUserAttribute;
  i: integer;
begin
  tvTest.JQTreeViewOptions.UIPlugin.PluginActive:= True;
  tvTest.JQTreeViewOptions.ThemesPlugin.PluginActive:= True;
  tvTest.JQTreeViewOptions.HTMLPlugin.PluginActive:= True;

  for i:=0 to tvTest.TreeNodes.Count-1 do
   begin
     aCGUserAttribute:= tvTest.TreeNodes[i].UserAttributes.Add;
     aCGUserAttribute.Attribute:= 'myhref';
     aCGUserAttribute.Value:= 'http://www.dmt.de';
   end;

  with tvTest.JQEvents.OnSelect do
   begin
    with BrowserParams.Add do
     begin
      BrowserScript:= tvTest.JQTreeViewOptions.UIPlugin.jsGetSelected + '.attr("myhref")';
      ServerName:= 'HrefValue';
     end;
   end;
end;

procedure TIWFrameTreeView.tvTestJQEventsSelect(Sender: TObject;
  AParams: TStringList);
var
  LMyHref: string;
begin
  LMyHref:= AParams.Values['HrefValue'];

  ShowMessage(LMyHref);
