[flexcoders] How can i connect two Boxes on apanel controls with a Line

[Baljeet singh]

Hi all,

 I want to connect two boxes with a line between them. I am using
moveTo(x1, y1) and lineTo(x2,y2) methods of Graphics class. But line
is  not getting created. I even tried with code like this:

 beginFill(x1, y1)
 moveTo(x1, y1)
 lineTo(x2, y2);
 endFill(x2, y2);

   But still no line is getting created. 

   I also want, whenever i drag and drop the boxes, line should remain
between them. 
  
  Any pointer/help will be highly appreciated.


Thanks ,

[flexcoders] Re: Tree collapses when dataProvider for tree changes

[Baljeet singh]

Hi,

Lets consider an XML as tree of nodes. Let me explain u the meaning of
"id".  My sample XML string look like:



 



   

 

   .
.
  

 





  Here my each XML node has unique Id attribute.

Now suppose I create a tree with this XML & i click on any node. For the
selected node, say node with id="5", i can find out the value of "id"
attribute of selected node & save this in session object. Means now i
have idea about which node i selected.

Now suppose , i create two children for selected node i.e for node with
id="5". So my XML changes somewhat like below:



 



   

 

   .

  < !-- Level 5th--->

 .
  

 





  So my dataProvider changes & tree gets collapsed.

  As we have already stored the id attribte value of selected node in
session. Now we can iterate over XMLListCollection to find the XML  node
with that  particular id value.

& Now  i use expandItem() method  & selectedItem property, providing
selected node. But  none of these things works.

Thanks & Regards,

Baljeet

[flexcoders] Re: Tree collapses when dataProvider for tree changes

[Baljeet singh]

Hi,

 Thanks for suggestion. But dataProvider has to be changed, &
accordingly tree changes.

 Considering XML as tree of  nodes, I am retrieving that particular
node when dataProvider changes on the basis of "id" attribute . Each
node is going to have unique value for "id" atribute in XML String.  By
this way i gets a XML object.

That XML object is used for expandItem() method or for selectedItem
attribute.

Thanks  & Regards,

Baljeet

[Baljeet singh]

Hi,

  Actually, i am using XML string, that is coming from server side. 
>From that XML string, i get the XMLListCollection as dataProvider.
When i click on selected node, either i am editing th information 
related to node or creating children. This edited/children information 
is stored in database.
 So, dataProvider changes(it's required). Tree is 
created on the basis of "id" attribute of each XML node . When 
dataProvider changes, i again retrieve that node on basis of "id" 
attribute. Then i tried to use expandItem() method, selectedItem etc, 
providing the retrieved node. But it's not working.

Thanks & Regards
