Tree view with editable cells?

Hi,
I have written a GTK+-2 based graphical visualizer for the NEC2 antenna simulation and analysis tool http://www.qsl.net/5b4az/pages/nec2.html and I am now considering a companion graphical editor for the NEC2 input file. This file is normally produced with a text editor and specifies antenna geometry and then commands to calculate various data regarding antenna characteristics (gain, input impedance etc).
Luckily the original NEC2 was written in FORTRAN and the input was punched cards with a fixed format, so the current file format is line-based and with a fixed number of parameters per line: you can get an idea by looking into examples files in http://www.qsl.net/5b4az/pkg/nec2/examples/
What I need is an idea on how to code a graphical line editor with editable cells for each parameter and the ability to add or delete lines as needed. The data in the cells may be numerical or textual or both and there may be inter-relations between cells, e.g. one cell may have a value that is a fixed proportion of another cell's value etc.
Tips please? Thanks!

Well, just about any language with bindings for gtk will work in a very similar manner. If I understand correctly, you might want to investigate the GTK treeview and GTK CellRenderer classes. Try to check the tutorials too.
Hope this helps.
Yes, thanks! Unfortunately though there is no easy way to have a spin button type editable cell, which would have been best for my needs. However, I found an example in a tutorial for the TreeView which could make a basis for a home brew second-best solution!

Tree View with BLOB

Ive displayed some workers with their departments in a tree view, but does somebody now how to put in their BLOB picture instead of their name into the tree view.
i thougt that i just rewrite the tree views "Node Text Template" but therefore i will need the image src??? so how to get the src from the BLOB picture from the table???
<tr>#INDENT#<td colspan="#COLSPAN#" valign="CENTER" class="tiny">#NAME#</td>
<td>
<img src=???????????? /> // it could be the worker number or something to get the blob src.
</td>
</tr>
Please help me.
thanks.

807703,
Can you set your name on the forum settings?
Ok, the item name is just an example, your just using it as a placeholder to pass the key to the picture you want to receive, if your tree is on page 3, create the item called P3_EMP_NO for example.
Your then setting the value of that item through the image source URL, and the application process can use it to present the right picture.
If you want to see a sample of this working in 4.0 take a look at my app on apex.oracle.com.
http://apex.oracle.com/pls/apex/f?p=9660:200 (tested in chrome only - should work on all browsers though)
Edit: Just checked compatibility - it works in IE and chrome but not firefox! Not immediately apparent why.
Page 200, login demo / demo2. (account has developer access so you can take a look at the page definition. There are only pictures for 4 photos).
Note the css in the tree view region definition to change the picture and line size.
'm guessing you're on 3.2 from your first post, I don't have 3.2 so I can't see where the img tag should go there (on 4.0 I put the url in the icon part of the sql query).

CS3/CS4 - Tree view with dynamic height/width

Hi,
I have a resizable panel that contains a treeview, when the panel is resized the treeview resizes but I would also like the treeview nodes to adjust their width. For the record, -my treeview nodes contain static text widgets and images.
Can I hook up some observers and manually resize the widgets when the panel resizes?
Kind regards Toke

If your node re-size needs are simple you may achieve it by setting e.g. kBindRight | kBindLeft on the appropriate widgets in the .fr file. For a complex view I'd extend PalettePanelView to create your own implementations of Resize (adapting the widget widths in there) and perhaps ConstrainDimensions.

Tree View Second level is not displaying bind parameter

Studio Edition Version 11.1.2.2.0appears this problem is addressed in
http://dailydevfixes.blogspot.com/2011/07/setting-bind-parameters-on-hierarchy-of.html
unfortunately I must be missing something.
as a test using the hr schema
I was doing a tree view with hire date as the first level then the employee id, last name and first name as the second level.
I hard coded employee id of 187 on a bean called by a button.
the first level is updated unfortunately the second level is not (employee id 107 should not show up)
--1999-02-07
----- 187 Cabrio Anthony
----- 107 Lorentz Dianahere is my bean the first level is updated but the second level is not not quite sure what I am missing
    public void ButtonClick(ActionEvent actionEvent) {
        BindingContext bindingctx = BindingContext.getCurrent();
        BindingContainer bindings = bindingctx.getCurrentBindingsEntry();

thanks I am working through that example unfortunately I ran into a problem
previously (in my real application) I was using bind parameters and my query had the following where clause.
( I did this to turn a comma separated list into an in statement)
WHERE    :Bind_Batch_NM_Comma_Sep_List IS NULL
         OR batch_nm IN
               (    SELECT REGEXP_SUBSTR (:Bind_Batch_NM_Comma_Sep_List,
                                          '[^,]+',
                                          1,
                                          LEVEL)
                              batch_nm
                      FROM DUAL
                CONNECT BY LEVEL <=
                                REGEXP_COUNT (:Bind_Batch_NM_Comma_Sep_List,
                              + 1)however in the example presented you are to create view criteria and there is a panel on the right called view object where clause but I can not figure out how to type into it directly
and I find it unlikely I can recreate this where clause using the add item button.
is there a way to manually type the where clause in the view object where clause box?

Hi,
Is there a "elegant" way to make blink a treeview node?
I am thinking to use a timer with the collection of nodes that I want to make the blink effect, and update the icon ...

Hi,
You can develop your custom control for this purpose. The logic you mentioned was correct. Here is a sample control that I developed by the logic you mentioned.
public class BlinkingTreeView : TreeView
private Timer t = new Timer();
private List<TreeNode> blinkingNodes = new List<TreeNode>();
public BlinkingTreeView()
t.Interval = 1000;
t.Tick += new EventHandler(t_Tick);
bool isNodeBlinked = false;
void t_Tick(object sender, EventArgs e)
foreach (TreeNode tn in blinkingNodes)
if (isNodeBlinked)
//update Icon
tn.Text = tn.Text.Substring(0, tn.Text.Length - 1);//to test
isNodeBlinked = false;
else
//update Icon
tn.Text = tn.Text + "*";//to test
isNodeBlinked = true;
public void AddBlinkNode(TreeNode n)
blinkingNodes.Add(n);
public void RemoveBlinkNode(TreeNode n)
blinkingNodes.Remove(n);
public void ClearBlinkNodes()
blinkingNodes.Clear();
public List<TreeNode> BlinkingNodes
get { return blinkingNodes; }
public int BlinkInterval
get { return t.Interval; }
set { t.Interval = value; }
public void StartBlinking()
isNodeBlinked = false;
t.Enabled = true;
public void StopBlinking()
t.Enabled = false;
just show me how to use BlinkingTreeView class. i will have tree view which will have few node and few nodes may have few child nodes. now how to achieve by this class BlinkingTreeView and show me how to blink few specific node not all. thanks

better to come with code. first populate tree view with some dummy node this way
Root
       Child1
                Child1-sub1
                Child1-sub2
       Child2
                Child2-sub1
                Child2-sub2
now blink Child1-sub2 & Child2-sub1. please come with code. thanks

Please Help(How to get RadioButtons in tree View)

Hi.
Sub/Requirement: How to implement RadioButtons in tree view with/without using xml file.
I have a requirement like this i want to display RadioButton in tree view.
I implemented tree same as which is given in sampleApplications.
In this sampleApplications they implemted tree by using xml file.
I also implemented tree by Generating xml file. In this xml file i get the values from the database. I am using <netui:tree > tag.
Is it possible to implement tree without using xml file. I need to generate tree Dynamically.
Please any one help me to come out with this solution.

The issue here is while you are retrieving all the details, you are consistently overwriting them in the request.setAttribute() call before you get to the JSP to display them.
Do you actually have a class/object called Student?
That object should have attributes for classes, subjects, teachers (all of which are lists apparently)
public class Student{
String name;
List classes;
List subjects;
List teachers;
// appropriate getter/setter methods
}Then you load each student, and populate its individual lists.
That lets you pass the list of students, each student having its own lists for display.
Hope this helps,

Folder list - tree view

I'm trying to build a tree view of an account's folders but I keep
running into a problem no matter which approach I take. In the code
snippet below I'm using the PopulateTree method recursively to add
nodes to the tree view. This works using the .NET GW API but when I
use SOAP it seems that I get my root folder, my Mailbox (which is
immediately below my root folder) but when the function recurses
against what should be a different list of (sub-) folders I end up
with the root and Mailbox folders in the next call to PopulateTree.
I've also tried doing the first level inline with the initializing
code, calling PopulateTree against each of the folders in the first
level as the parent folders but I still seem to only get the root
folder and Mailbox again within the foreach loop of the PopulateTree
method. Otherwise, I can list all the folders in a text string if I
ask for a recursive listing.
treeFolders.Nodes.Clear();
PopulateTree(treeFolders.Nodes[0], "Folders");
private int PopulateTree(TreeNode parentNode,
string parentFolderID)
WR.getFolderListRequest flreq =
new WR.getFolderListRequest();
flreq.recurse = false;
flreq.parent = parentFolderID;
WR.getFolderListResponse flres =
ws.getFolderListRequest(flreq);
if (flres.status.code != 0) return flres.status.code;
TreeNode localNode;
int folderCount = flres.folders.Length;
foreach (WR.Folder folder in flres.folders)
localNode = parentNode.Nodes.Add(folder.name);
PopulateTree(localNode, folder.id);
localNode = null;
return 0;

Right call it once recursive, and then cache in Map or similar structure.

when i click in one cell (it is a textfield) where there is no more written text it marks the hole cell and when i start to write, it overwrites the whole text.
i would like the cursor to be placed at the end of the field in this case.
when i click in the cell where there is written text it is ok - it puts the cursor to the clicked position.
thanks very much for your help
Helmut

Assign focus on text field associated with tree item in edit mode

The JavaFX home page has an example for how to edit the label associated with a tree item using a cell factory (see sample code below). However, if you select a tree item and then either mouse click or select the Enter key to start editing, the text field doesn't get focus even though the startEdit() method invokes textField.selectAll(). I tried invoking textField.requestFocus(), but that didn't work. Is there a way to ensure that the text field gets focus when the tree item is in edit mode?
I'm using JavaFX 2.1 GA version on Windows 7.
Thanks.
Stefan

When you click on a selected tree item to start the edit process is the text in the text field selected? In my case the text is not selected and the focus is not on the text field so I have to click in the text field before I can make a change, which makes it seem as if the method call textfield.selectAll() is ignored or something else gets focus after method startEdit() executes.

Sharepoint 2013 list view quick edit does not work with out remote API permissions

sharepoint 2013 list view quick edit does not work with out remote API permissions.
When I give Use Remote Interfaces - Use SOAP, Web DAV, the Client Object Model or SharePoint Designer interfaces to access the Web site it works which is not an ideal situation..

This is true. If you use Fiddler to watch the requests from the list view quick edit you can see CSOM calls. For example when changing a value in a cell, when you tab out you will see the SetFieldValue and Update method calls on the list item.

A tree-view in HTML page with nodes generated with java script in run time is not visible in the UI Automation Tree. Need Help

I have a HTML page with an IFrame. Inside the Iframe there is a table with a tree view
<iframe>
<table>
<tr>
<td>
<treeview id="tv1"></treeview>
</td>
</tr>
</table>
</iframe>
In UIA, i am able to traverse till the tree view but not able to see it.
I have used the TreeWalker.RawViewWalker Field to traverse the node from the desktop Automation.RootElement.
I tried to use AutomationElement.FromPoint method to check whether i am able to get that element. Fortunately i was able to get the automation element.
i tried to get the path to root element from the node element using the TreeWalker.RawViewWalker. I was able to get the parent path to the root element.
But trying the reverse way like navigating from root element to tree node, was not getting the element for me.
Please help me with suggestions or inputs to resolve this issue.

Thanks Bernard,
It works fine with JInitiator but not working with
the JPI. For JPI what settings I need to do ??hi TKARIM and Bernard, i am having similar problem even with the Bernard's recommended setup. could you post the webutiljini.htm (i presume you are using config=test) ?
i am actually using jinitiator 1.3.1.28 with Oracle HTTP Server of OAS 10gR2) calling Forms Server 6i (f60cgi). After setting up according to Bernard's recommended setup steps, the java console showed that it loaded the icon jar file when it could not read the form, but it skipped the loading of the icon jar file once it read and started the form. How do we specify in the form to pick up the icon from the jar file instead from a directory ? Or do we need to specify ? Any ideas ?
Thx and Regards
