How to write an element in a JTable Cell

Probably it's a stupid question but I have this problem:
I have a the necessity to build a JTable in which, when I edit a cell and I push a keyboard button, a new Frame opens to edit the content of the cell.
But the problem is how to write something in the JTable cell, before setting its model. Because, I know, setCellAT() method of JTree inserts the value in the model and not in the table view. And repainting doesn't function!
What to do??
Thanks

Hi there
Depending on your table model you should normally change the "cell value" of the tablemodel.
This could look like:
JTable table = new JTable();
TableModel model = table.getModel();
int rowIndex = 0, columnIndex = 0;
model.setValueAt("This is a test", rowIndex, columnIndex);
The tablemodel should then fire an event to the view (i.e. JTable) and the table should be updated.
Hope this helps you

How to blink the text with in JTable Cell?

Hi Friends,
I am relatively new to Java Swings. I have got a requirement to blink the text with in the JTable cell conditionally. Please help with suggestions or sample codes if any.
Thanks in Advance.
Satya.

I believe Swing components support HTML tags.
So you might be able to wrap your text in <BLINK>I am blinking !</BLINK>
tags.
If that doesn't work, you probably have to create your own cell renderer, and force a component repaint every second or so... messy.

Owen

How to write each element of a set to the excel sheet?

I am trying to iterate through each element of the set and write each of them to an excel file? Can Somebody help me to achieve this?
Code snippet is:
Iterator<String> nameIterator = names.iterator();
for(int size = 0;size<names.size();size++){
row = mdm_lastLoginDate.createRow(size);
//cell = row.createCell(1);
while(nameIterator.hasNext()){
String setName = nameIterator.next();
cell = row.createCell(1);
cell.setCellValue(setName);
System.out.println("setName:->"+setName);
mdm_lastLoginDate.autoSizeColumn(size);
above code prints each element in the console but not getting each value in the excel file. I am only getting the last value.
Thanks & regards
Amita

How to write set Element in Java

Is there a way to write the following in java so I can do it in a method?
<set property="inputValue" value="${bindings.SubCommandId.inputValue}" target="${data.ServiceEventEditUIModel.SubCommandId}"/>

I solved it:
JUCtrlValueBinding sub = (JUCtrlValueBinding)ctx.getBindingContainer().findCtrlBinding("subCommandId1");
sub.setInputValue(null);

How to write text vertically in an table cell?

Is it possible to make a table cell where the
text would be written along a vertical base line?
I found how to make a text box and rotate it
vertically.
How may I place such a text box in a table cell?
dan

Hello daniel,
if the table will not be resized or repositioned a lot, the best way to display what you want to have is to create a textbox with the styles and adjustments you need, rotate it and place it over the table cell. Be sure to make the cell big enough to pretend the text of the textbox would be inside of it. The textbox has to be a fix positioned object in the top layer.
It's only a work-around, but the best you can achieve.
Frank.

How to display cusomized custom tooltip(jwindow) in jtable cell position

Hi,
i am trying to display custom tooltip for jtable cell. i created custom tooltip(jwindow) and on mouseover of jtable cell i am trying to display the custom tooltip.
But it is not display the position of jtable cell. How to display the exact position of jtable cell
please help me on this.

Did you read the posting directly below yours which was also about a custom tool tip?
JScrollableToolTip is buggy
The code presented there shows the tool tip in the proper location.
For more help create a [url http://sscce.org]SSCCE, that demonstrates the incorrect behaviour.
Don't forget to read the "Welcome to the new home" posting at the start of the forum to learn how to use the "code tags" so posted code is formatted and readable.

Read up on cell renderers from the Swing tutorial on "Using Tables":

How to write a composite element in iterator?

Hi,
I want to write a composite element in iterator which has the same result as BSP element like this in BSP layout:
<htmlb:link id = "link1"
              reference = "http://www.sap.com">
<htmlb:textView id = "text1"
                  textColor = "<%=gv_color%>"
                  text      = "ddddd" />
</htmlb:link>
Do you know how to write this in iterator? Thanks!

Hi,
you can use the replacement bee:
data: o_link TYPE REF TO cl_htmlb_link.
CASE p_column_key.
    WHEN 'column_name'.
        w_event = model->get_sapevent_string(
                        name    = 'activity'
                        system = 'crm'
                        key     = o_ref->guid ).
        o_link    = cl_htmlb_link=>factory( id = p_cell_id
                                          text = 'text'
                                          tooltip = 'tooltip'
                                          reference = w_event ).
        p_replacement_bee = o_link.
ENDCASE.
in w_event you declare your event, eg. the calling of a
sap event or you navigation.
you can find an example in:

How to write contents of an ArrayList to JTable

I have an ArrayList named 'innercell'. It contains the following contents
cs123, 0.34567
cs234, 0.5673
cs234,cs456, 0.5674
this arraylist is added to another arraylist 'cells'
cells.add(innercell);
now the contents of the 'cells' arraylist is
cs123, 0.34567
cs234, 0.5673
cs234,cs456, 0.5674
i have created a JTable and its variable name is 'jtable' (object) (*i'm using NetBeans IDE 6.0*)
and the model of this JTable is as below (it is the generated code by NetBeans IDE 6.0)
jtable.setModel(new javax.swing.table.DefaultTableModel(
new Object [][] {
{null, null},
{null, null},
{null, null},
{null, null},
{null, null},
{null, null},
{null, null},
{null, null},
{null, null}
new String [] {
"Title 1", "Title 2"
Class[] types = new Class [] {
java.lang.String.class, java.lang.String.class
public Class getColumnClass(int columnIndex) {
return types [columnIndex];
i have only 2 columns in the table, and 9 rows
now i want 2 place contents of 'cells' arraylist to JTable as below
Tittle 1 Title 2
cs123 0.34567
cs234 0.5673
cs234,cs456 0.5674
to write in this form i'm using following code
String[] columnNames={"Title 1","Title 2"};
Object[][] rowdata=new Object[9][2];
str=items;//items is the string value.the possible 'items' values {cs123,...}
sup=value;//value is the double value. the possible 'value' are {0.5674,......}.i'm not given how i'm geting these values
for(int k=0;k<2;k++){
if(k==0)
rowdata[i][k]=str;
else
rowdata[i][k]=sup;
jtable=new JTable(rowdata,columnNames);//is this statement is right to add the contents of arraylist to the table?
jtable.setVisible(true);
but it is not working....i'm getting "NullPointerException"

Swing related questions should be posted in the Swing forum.
Don't forget to use the [Code Formatting Tags|http://forum.java.sun.com/help.jspa?sec=formatting], so the posted code retains its original formatting.
Don't use an IDE to generate your code. Learn how to write your own code. Its hard enough to learn how to use Java without learning how to use the IDE as well.
Use the DefaultTableModel. You can build the model using Vectors or Arrays or by adding individuals rows of data to the model. There is no need to create a custom TableModel.

How to write the expression when create the calculated column?

Dear,
I want to create some calculated column in my attribute view, but I don't know how to write the code in the expression, is there any introduction about this part, how to use those function and how about the grammar in this expression code ? or is there any example about this calculated column?
Thanks for your sincerely answer.

Hi Zongjie,
you can find some information about the creation of calculated columns in the HANA Modeling Guide (http://help.sap.com/hana/SAP_HANA_Modeling_Guide_for_SAP_HANA_Studio_en.pdf).
Within chapter 6.2.1 (Create Analytic Views) you can see under point 7 some basics and also a simple example. The same is also valid for Calculation Views.
Chapter 8.9 (Using Functions in Expressions) describes the different available functions.
You also can use the integrated search in the HANA Studio by clicking the "?" button in the button left corner. Then you get some links in the side panel with related information.
In general you can write your expression manually or you can just drag and drop the functions, elements, operators into the editor window. For example if you drag and drop the "if" function into the editor window you get "if(intarg,arg2,arg3)" inserted. The arguments can be replaced manually or also by drag and drop.
It is also worse to use the "Validate Syntax" button on top of the editor window. It gives you directly a feedback if your expression syntax is correct. If not you get some helpful information about the problem (ok, sometimes it is a little bit confusing because of the cryptic error message format ).
Best Regards,
Florian
