How to disable certain columns of a Table?

hi all,
I wish to fill a pattern of 8 digital signals (only 1's & 0's) in a Table.
Is there any way to restrict the user from typing char or num other than a 1 or a 0?
Since the table is a string, I'm having confusion how to do this.
Secondly, the table would have by default 12 columns visible on the Front Panel, excluding both the headers.
But the No. of Columns is based on a parameter called Duration that ranges between 4 & 256.
What I want the user to do is to key in 1's & 0's for the Duration chosen.
Since it'll be tedious to key in for large values of Duration, I've given the option of Set Row(s) & Reset Row(s),
that will fill with either 1 or 0 respectively for the chosen Row Value.
Is there any way to disable the remaining columns of the Table, ie, those unfilled columns,
when the user scrolls horizontally? I don't know how to achieve this.
I went thro' the Properties of the Table, I don't understand some of their functionalities,
like SelStart, SelSize etc.
I wonder why a Property like Disable Array Elements for Arrays is not provided for a Table
to Disable the columns we want to do so, or is it my gross ignorance, I don't know.
Experts pls clarify me & help me out.
Regards,
Partha.

Another option is to do this:
Slightly more elegant, but also more potential for bugs (e.g. the users can tab into the column).

You can lower your overhead by using these "professional" looking indicators and controls. They are limited in functions and properties, thereby causing a smaller VI in file size.
Nice. I didn't think about that. Looks like a VI with a single system boolean takes ~20% less space than one with a standard boolean.
P.S. In general, I would say there are considerably better arguments for using system controls than memory issues.
Try to take over the world!

Disable first Column in jTable

Hello people my problem is I use jTable and in the table I need to disable first column so that the user is not able to change edit the values that are listed in this column. Please help me with some code samples if possible. Thanks in advance.

A custom table model makes this simple. You just override the isCellEditable method and return false when the column index is 0.

How to disable a column in Advance Table

Hi All,
I have an advance table, for which one of the column is MessageTextInput I want to disable this column programatically on certain condition for a particular row, is this should be implemented by switcher else is there a better way.
Thanks in advance

switcher is the best way to implement this problem.
You can also use SPEL expression, which is very easy to implement.
Eg,
Set the SPEL expression for readOnly property as ${ReadOnlyFlag} // where readOnlyflag is a boolean attribute in the VO of respective region.

How to disable a Column for a particular row in Advanced Tables

Hi All,
We are using an Advanced Table for search criteria. Our requirement demands to disable a column (we are using messagechoice item in that column) for only first row. We use standard Add Another Row functionality to add the rows.For the remaining rows it (message choice) should be enabled. Can anyone help me to solve.
Regards,
Sundeep

You can either use a Switcher or OADataBoundVariables for this.
Please see the section OADataBoundVariable in the dev guide. Based on certain View Attribute value, you can set the specific column in the table as Read Only.
Switcher can be very similar too. Decide an Attribute for the Switcher and make sure the first row (which you want to disable) has some specific value. All other rows should have some other value. Decode can help you here. Then you would need to create two cases. Under the specific to first row, have a read only item. For the other case, have an enterable item. A little read through of the Switcher chapter in the Dev guide would clarify the doubts if any.

Moving columns in JTable

hi all
i'm having a slight problem after i've moved a column within my JTable, i need to reallocate the column index numbers. i'm using a sorter for the data, so when i move a column and select another column (or that one) it sorts a different column to the one selected based on the original (pre-move) indexes ( i do hope that makes some sense).
i have a mouseDragged listener which works fine when moving a column, i just now need to add the index changes for all columns to it but i keep coming up with very very bad code that doesn't work.
any suggestions would be most appreciated.
thanks heaps...
Takis

i've actually been fiddling with those and that is actually where my problem lies.
i use the following:
int viewColumn = columnModel.getColumnIndexAtX(e.getX());
int column = tableView.convertColumnIndexToModel(viewColumn);
the sorter then works on "column".
problem is, that when the column is moved, the viewColumn changes, but the column value remains the same. i've also tried sorting on the view column but then it gets even more confused.
i just can't seem to figure it out...

Moving Columns in Jtable. Columns not in sync with header

Hi,
I got several tables within a scrollPane. So I use the add method on the scrollPane to add them. In order to see the headers I add the header separately :
add(table.getTableHeader());
add(table);
The problem is the following :
When I am moving my Column around, the header moves around, however the columns don't move ! So The header does not correspond anymore to my column !
Do someone have some ideas how to get ride of that problem ?
Thanks
Emmanuel

One thought: Add the tables to another container, such as a JPanel and then add the panel to the JScrollPane

How to set a column in JTable non-editable?

I have a JTable, and how can I set a particular column non-editable?
Thank you.

You could create a sub class of DefaultTableModel, you pass the column number to the constructor or you add a method like setColumnEditable(0, false); to set column 0 non-editable.
You overwrite the method isCellEditable so it will return false when the column number that is passed to the method is 0 (if you want to have column 0 non-editable).

How edit/focus/resize columns of JTable that is node of JTree?

I have added a JTable as a node on a JTree, but now I can't interact with it. I think that it is because all mouse/selection actions are grabbed by the JTree. However, I can't figure out how to pass these on to the table.
What method do I call? I can't seem to find a way to get which column I have clicked over, and even if i did, i can't find a method to actually select it!
please help!

Hi,
your questions I had got some time ago, and I solved the problem . It means you will as well.

How to disable some "columns to display"?

Hello!
I have one management pack (it's monitor some our network devices), which was written by contractors for our company. This mp have many unnecessary columns in it's view. I deleted some of these <ColumnInfo>
from mp (.xml file). Then I import mp but these columns
have not disappeared.
Can anybody help me? What should I do to remove these columns?
P.S. I know that I can disable them with "Personalize view", but I want to do it
centralized (all of the console users must see these changes).

Hi,
Since the MP was written by contractors, it is better to contact them edit the column.
Meanwhile, after importing the management pack, please re-create monitor for
a test.

You get an exception because the table doesn't have a column at index anymore, but you can still ask the model.
table.getModel().getValueAt(table.convertRowToModel(row), 3);
