Dynamic input to create JTree

I provide path in String form
Example:
/home/fsloke/chemistry/1.txt
/home/fsloke/physic/2.txt
/home/fsloke/physic/general/3.txt
Expected output in the tree
+Home
+ fsloke
+chemistry
- 1.txt
+physic
-2.txt
+general
-3,txt
I headache now. How I should put the String into JTree form
I think about recursive ... but I can't construct the Tree....
One more problem:
Last time I play with lical file system, here I can compare which is directory and which is file. In experience that when we are using the DefaultModeITree, we should have child to attach with root so the root can appear as Directory icon.
The problem is when our Directory do not have any attach to it, the icon will become paint file.... NO longer Directory icon
*** I hope you all can understand what I expressing... Cheer...

You can use <b>Value Help Configuration Wizard</b> for multiple selecion of rows to act as input for another table or form view.
The wizard generates an embedded iView that represents the value help dialog box and its functionality. Next to the input field, the wizard also generates a value help button. At runtime, when the user presses the button, the dialog box appears and lists values for the input field.
In your case you can select multiple rows by enabling "Multiple selection" while creating the Iview.
Have a look at <a href="http://help.sap.com/saphelp_nw04s/helpdata/en/b5/036d391f074f769e00602634ee9960/frameset.htm">Value Help Configuration Wizard</a> for more details.

Dynamic input

Hi
I am displaying a SAPSCIPT through program.Before displaying it I have to choose groupvalues or individual value.If it is individual then i don't have any problem because I have to display the dialog box which accepts details and current status values of that particular individual only once.But I don't know how to display dailog box which accepts these 2 values dynamically without knowing the number before for groupvalues.Because the group which we select may have 3,4 or any other number of individual values.Please help me.
Thank You.

read JTree constrcutors in which u can use Vector for creating JTree like new JTree(myVector);
and in this myVector u can store your own objects and override toString() method of that object (stored in Vector), but as my practice its not good.
2.How Japplet connect to a database and get data?
You have to make signed applet for connecting your applet with database , and sorry to say but ita a real pain in your -------------

How i can dynamic changing root in JTree in swing?

Hello, how i can dynamic changing root in JTree in swing?

If u r willing to get your hands dirty and not be lazy, you can look around the code for the DefaultTreeTableModel and implement the setRoot functionality in the FileSystemModel. The code should not be too hard to figure out, cause it only replaces the root Object and fires a TreeStructureChanged notification.
Set root functionality from DefaultTreeModel source (in your JDK installation directory)
     * Sets the root to root. A null root implies
     * the tree is to display nothing, and is legal.
    public void setRoot(TreeNode root) {
        Object oldRoot = this.root;
     this.root = root;
        if (root == null && oldRoot != null) {
            fireTreeStructureChanged(this, null);
        else {
            nodeStructureChanged(root);
    }ICE

Creating JTree by JTable Data

Hi,
I want to create JTree for the data in JTable, Is it possible. Thanks

This question is a repeat of your last posting:
http://forum.java.sun.com/thread.jspa?threadID=648759&tstart=0
and you still haven't followed the advice given there. Quit cluttering the forum with the same question
I will first explain what I want. I wanna 3 structures: TextField,JButton, and JTable.The Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/list.html]How to Use Lists has an example that is identical to this except that it uses a JList instead of a JTable. However, the concept is the same.

Dynamically creating JTree

Folks - I'm new to Java and hence requesting some assitance in something I'm working on. I want to read a ascii file that constains some containment hierarchy eg., The file is listed below.
<pre>
# First field is parent, and fields seprated by '=' are childs.
NodeA=NodeC, NodeD, NodeE
NodeE=NodeZ,NodeK
NodeK=NodeF
</pre>
I have no problem in reading the file, and parsing/tokenizing it at all.
How can I use the information here in creating a dynamic JTree.
Any help would be greatly appreciated.

</pre>
I have no problem in reading the file, and
parsing/tokenizing it at all.
How can I use the information here in creating a
dynamic JTree.
Any help would be greatly appreciated.- i assume that every node is named something unique and there can be no duplicates
- can you guarantee the order of the file? Is it always from the root downwards? ie. can you guarantee that the when you see "NodeE" in the first line that NodeE has not already been created? these details will greatly affect your algorithm. typically if you can guarantee a certain order or format of the file, it will greatly improve the efficiency of the algorithm
- here's an algorithm that would do the tree-building line by line, regardless of order, assuming no two nodes can be named the same thing, but it would probably be better to read in the entire file, storing the information in a vector or something and then go through all the data at once
- this algorithm should be applied after every line is read in; after the last line in the file is read in, the entire tree will be created: how do you know what is the root node?
- read in each line as: parent, child1, child2, etc...
- if a node named "parent" has not already been created, create a node named "parent":
DefaultMutableTreeNode node = new DefaultMutableTreeNode(parent);
- for each child, if a node named "child1" has not already been created, create a node named "child1" and add it as a child to "parent"
DefaultMutableTreeNode child = new DefaultMutableTreeNode(parent);
node.add(child);
- this algorithm is a pain because you always have to check if a node has already been created

Dynamic table rows created based on input value

I've been searching the forum for either a tutorial or input
on how to create a table where the number of rows are based on a
user input value. I can't seem to find anything on this.
Here's what I'm trying to do. I have site where people are
charged based on the number of items they register. So if they want
to register 2 items. They would input the number 2 for quanity and
I would display a dynamic table with 2 rows. The user will input
their data for the 2 items and I insert this into an
itemsRegistered table. If they entered 4 I would give them 4 rows
for input. I am using dreamweaver with PHP and MySql database. Can
anyone point me in the right direction. Any help would be
appreciated!

Not exactly. The items are all the same but have a different
registration number (like a serial number). So if the user wants to
register 2 items. They would input the number 2 on the form. Then 2
rows would appear on the table, one for each registration number.
When they finish entering the data it would be inserted into the
database as 2 records.
So for example if item 1 has registration number 10000 and
item 2 has registration number 11000. The registration numbers are
unique. The table would look like this :
CustomerID (links to customer table)
RegistrationID (Unique in this table)
ItemColor
ItemShape
I don't know if I've explained this well but thanks for even
attempting to answer this! I really appreciate it!

Re: Including Applet in JSP with Dynamic input| Help needed

Hi All,
We are into a project in Oracle Portal Server where in we want to embed a result of a standalone application in Portal page.
We can do that once we can embed the result of the standalone application which generates applet based on the input it gets from the current application's database.
If it was static we could have used jsp:plugin but, it fails in our case!
We are clueless as to how to embed an applet which will pick up the data dynamically.
Can anyone of you help me in this regard?
Thanks & Regards
Arthi

Hi Arthi,
I think this might help you to get an idea why jsp:plugin tag does not allow for dynamically called applets.
<jsp:plugin type=applet height="100%" width="100%"
archive="myjarfile.jar,myotherjar.jar"
codebase="/applets"
code="com.foo.MyApplet" >
<jsp:params>
<jsp:param name="enableDebug" value="true" />
</jsp:params>
<jsp:fallback>
Your browser does not support applets.
</jsp:fallback>
</jsp:plugin>
The plugin example illustrates a <html> uniform way of embedding applets in a web page. Before the advent of the <OBJECT> tag, there was no common way of embedding applets. This tag is poorly designed and hopefully future specs will allow for dynamic attributes (height="${param.height}", code="${chart}", etc) and dynamic parameters. Currently, the jsp:plugin tag does not allow for dynamically called applets. For example, if you have a charting applet that requires the data points to be passed in as parameters, you can't use jsp:params unless the number of data points are constant. You can't, for example, loop through a ResultSet to create the jsp:param tags. You have to hand code each jsp:param tag. Each of those jsp:param tags however can have a dynamic name and a dynamic value.
I think you can get better information if you look in to the below link
http://pdf.coreservlets.com/CSAJSP-Chapter12.pdf
Many Thanks,
Ramesh.

Dynamic input form in ADF

Hi,
i need to create an input form in ADF, which contains radio groups ,check boxes ,LOV's and text boxes as form fields.
these form fields i need to configure in DB specifying the type of the UI component(LOV,Text fields or Radio or check box)
by reading the type, UI component has to be rendered and validations should be fired dynamically.
is it possible in ADF?
Thanks
Indu

ADF Faces offers a library of dynamic components that includes dynamic form and
dynamic table widgets that you can drop from the Data Controls panel. Dynamic
components differ from standard components in that all the binding metadata is
created at runtime. This dynamic building of the bindings allows you set display
information using control hints on a view object instead of configuring the information
in the Edit Form Fields dialog as you drop the control onto the page. Then if you want
to change how the data displays, you need only change it on the view object, and all
dynamic components bound to that view object will change their display accordingly.
With standard components, if you want to change any display attributes (such as the
order or grouping of the attributes) you would need to change each page on which the
data is displayed.

Schedule Module program in Background with Dynamic Input values ?

Hi,
I am trying a schedule a Standard Transaction which has Month,year and other Check boxes (By default they are Empty) .I need to schedule it monthly and Input must change dynamically when I run in background each month..
How do we do this?
Regards
Vara
Message was edited by: Vara K

You can not directly schedule a module pool program in background job. These are usually reports. What you can do is create a custom report program with your parameters on a selection screen. In this program you can do a BDC over the standard transaction filling the parameters from the selection screen of the custom program. This custom program can also have a selection screen variant which uses selection variables that will change dynamically. Then you can schedule the custom report program via SM36.

How to build dynamic input schedule from version

Hi experts,
I want to create an input schedule based on my category selection which will allow users to enter data to budget part but changing the actual part is prohibited.
For example I have category member which is 2010-09-1. This means I am working on 2010 Budget which has 9 periods of actual and 3 periods of forecast and 2011 Budget. In my input schedule I would have 24 months from 01.2010 to 12.2011 and I will copy actual to budget for the first 9 months but I do not want users to change first 9 months actual data from input schedule.
What solution can you propose for this in BPC NW ?
Regards,
ergin

Hi Ergin,
From the description you have provided, I guess you will have the TIME dimension in the Column. The CATEGORY would be set to 2010-09-1, lets suppose. In this case, the first 9 columns should be locked for any changes. For this, you need to use the Data Validation technique, which is native to Excel.
select an empty cell, lets say D1. in this cell, you should fetch the value "2010-09" from the version "2010-09-1". If the version is changed to "2010-10-1", the cell D1 will be automatically updated and will show "2010-10". In the column, in the row just above the Time dimension, write a formula to fetch the year and monthnum property of the Time member. Lets say, the time dimension members are displayed in the cells E4 to AB4 (24 columns for 24 months). In the cell E2, you can write the formula, =EVPRO("application name",E$4,"YEAR")&"-"&EVPRO("application Name",E$4,"MonthNum"). This will return 2010-01 in the cell E2 for the member 2010.JAN. Similarly, for 2010.FEB, the cell should display "2010-02". We will keep the formula in E2 only. After the expansion, the formula also will be expanded for the other cells.
Select the first data cell of the EVDRE report. Open Data Validation. In the Settings Tab, in the Formula field, write =D1>E$2. Then go to the error alert tab and choose the style as stop and give some title and message. This would typically mean that if value of D1 (in this case 2010-09) is not greater than E2 (in this case 2010-01), then the error message will be displayed, when we try to enter values in these cells. And it will not allow to enter any value.
Once the EVDRE is expanded, this data validation will be copied into all the other data cells. So, in this way, the enter input schedule can be kept dynamic.
Hope this helps.
