Hello,

I have another question regarding the TIWCGJQTreeView / TIWCGJQTreeViewItem
component. Is it possible to implement an OnMouseOver-Event for the TreeViewItems?

Or is there a different way to get the TreeViewItem which is subjacent to the mouse cursor?

Kind Regards,
Ingo Tröger

Hi itroeger,

Implemented in V1.6.0.2622.

Thanks.

Best Regards.

Hello

I hope you're not going to use Mouse events that goes to server.

Hello,

I think it should work with a clientsite mouse event. I just need to get
a property of an object which is linked to the TreeViewItem.

Thanks for the top support!

Kind regards,

Hello,

I need to know the node which fires the OnHoverNode event.
Is there a similar way like the one to get the selected node (jsGetHovered)?

Code: Select all

with tvFolderCG.JQEvents.OnHoverNode do
   begin
    with BrowserParams.Add do
     begin
      BrowserScript:= tvFolderCG.JQTreeViewOptions.UIPlugin.jsGetSelected + '.attr("id")';
      ServerName:= 'NodeID';
     end;
   end;


Kind regards,

Hi itroeger,

As my colleague said:

if you will do this, will cause slowness..

For client side, you should use OnHoverNode.Script property.
For get uniquename or user attr, you should do this in OnHoverNode.Script:

javascript code

var myattr = $(data.args).attr("uniquename"); // or custom attr

Best Regards.

Hi cgdevtools,

thank you for your patience.
For test purpose I have a main form and a frame with a
treeview on it. On the main form is a button to display
the frame after click.

Within the ProcessCommand procedure of the frame I placed
the following code:

delphi code

tvTest.JQEvents.OnHoverNode.Script:=
   'var myattr = $(data.args).attr("uniquename");';

Now, when I want to display the frame by clicking the button
it is not displayed. Without the codesnippet it is displayed.
Is there a trick how to solve this problem?

Kind regards,
Ingo Tröger

Hi itroeger,

You missed important things...please see attached demo.

P.S: I found the small issue in jquery plugin. When node is expanded/collapsed, sometimes plugin send wrong data object.


Best Regards.
