Multiple Cell Selection inJTable

I want to select multiple cells ( 4 consequent cells) with single mouse click.The problem is the 4 cells are getting selected ,but the border is being set to only one cell on which i clicked,but the selection background color is set to all the four.
i want the border to be included for all the four cells ,so that it looks like i have selected a set of cells .
waiting for a reply.
please help.

In order to accomplish this, you will have to drastically modify the UI delegate for JTable. The difference between the areas you are speaking of is that one is the 'selection' and the one with the border is the 'focus' cell which represents the 'anchor' of the selection.
The actual routines that paint the table cells are marked as private in the BasicTableUI class, so that is not a workable solution.
Let this be a lesson to all Java programmers (ahem) about making critical methods private!

Multiple Cell Selection Scaling Factor Issue within BEX

We have a report which we need to create views from where each view is simply a different scaling factor within 20 rows of a 50 row query.
Within WEB reporting, you can simply select all the cells you want, and then select the proper scaling via the context menu.
When you try to do the same thin in BEX though, only the first cell that is selected within the total selection is changed to the desired scaling factor selected.
So...is this a bug? ...and/or how can we selectively change the scaling for multiple cells within BEX?
You can of course selectively choose which figures should have a specific scaling, but we need views saved and not queries for this....and to my knowledge you can't save views out of query designer.
any thoughts?

When you try to do the same thin in BEX though, only the first cell that is selected within the total selection is changed to the desired scaling factor selected.
are you trying to do this with cell references or are you doing it for the entire row/ column ?
you can create cell refernces for the cells that require differenr scaling factor in the query designer and then using cell properties you can define a scaling factor of your choice.
To create a cell refence simply double click that cell OR right click>create new cell refernce.
then you will be able to see cell properties where you can define desired properties.
Hope this helps you.

Contiguous and non-contiguous multiple cell selection in JTable

I desparately need your help on this.
My appliaction contains a JTable. The users should be permitted to select multiple cells (both contiguous and non-contiguous) using
Ctrl + Click -- add that cell the already existing selection
Shift + Click -- add all cells in the range to the selection.
I like to have the selection behaviour as that in Excel (where you could ctrl + click on any cell to add it to selection).
Questions:
==========
Is this behavior possible using JTable?
How to do this?

Hi, use
JTable table = new JTable();
DefaultListSelectionModel dlm = new DefaultListSelectionModel();
dlm.setSelectionMode( ListSelectionModel.MULTIPLE_INTERVAL_SELECTION ); //1( the first one should be the one you are looking for)
or (choose 1 or 2, the rest stays the same)
dlm.setSelectionMode( ListSelectionModel.SINGLE_INTERVAL_SELECTION );//2
table.getColumnModel().setSelectionModel(dlm);
table.setCellSelectionEnabled(true);Hope this helps.
Greetings Michael.

Multiple Cell Selection in a JTable (again...)

Hi All -
I'm trying to get a JTable working well with the ability to select multiple cells in the way you'd expect to be able to (in Excel for example). By this I mean, hold down ctrl to add to a selection, hold shift to select between the last selection and the new one, be able to drag multiple regions with the mouse and have them be selected.
I've seen lots of talk about this, for example on this thread:
http://forum.java.sun.com/thread.jspa?threadID=619580&start=0&tstart=0
(the code here will not work in the 'general' case, for example it doesn't really support dynamic table resizing)
...and found some pretty extensive code from here:
http://www.codeguru.com/java/articles/663.shtml
...that kinda half works. (but the selection model is very strange once you get it running. Not at all what the average user would be used to)
Does anyone have this working 100% with code they can share? It is very surprising to me that this is not the default behavior in Swing to be honest.
I'm sure that I can come up with a solution for my situation, but I may as well not waste the time if someone already has something working for this.
Thanks!

If you have columnSelectionAllowed,rowselectionAllowed and cellSelectionEnabled then you can select cell by cell if you use the control key,
Now the problem is, if you don't have input by your keyboard, in my case, I have a big table and I need to select diferent cells that match a certain criteria,
jTable2.setRowSelectionInterval(j,j); //but this only works not for different rows 5 - 120 - 595
I'm trying to use:
jTable2.changeSelection()
but still don't have good results....
If any one could help to this matter will be really appreciated...
thanks...

Multiple cells selection after research

Hi to everyone,
i'm trying to create a function word-find into a JTable (like the fuction - find on this page CTRL F).
Now my method, when there are two or more same objects in the table, selects(with a differrent cell background) only the last one object find.
How can I select all the right elements found?
I hope I've been enough clear.
Thanks a lot for the help
Jas

Thanks for the suggestion, but in this case is not
the best solution, because I would have to modify
several classes.
This function would be only an added to one already
existing application that contain many classes.Well the JXTable extends JTable, so the change would be minor
Wouldn't be an other possibility/solution?Other than using something already created by someone else?

Mulitple Cell selection with unselect the same Cell

Dear Friends,
I am having a JTable with a Multiple Cell Selection .Consider Now iam
selecting the cell (0,3) (0,5) (1,7).When selecting the cell it is in Red color.
I made this multi selection by using the setCellRenderer method overriding.It works fine.
Now I am clicking the Same above cell with right click button in the mouse ..it must unselect ....means It may change the color too.
Any body know about this....Can u please help me ...This is very urgent for me........
Kindly
malar

Thanks friend,
I have finished that..Now its working fine....
I used the same cell renderer with deleting the existing index which was selected....And I called the repaint() again....Now it unselected.
Thanks for ur simple and cute Idea....Thanks a lot

How can I select multiple cells in tableview with javafx only by mouse?

I have an application with a tableview in javafx and i want to select multiple cells only by mouse (something like the selection which exists in excel).I tried with setOnMouseDragged but i cant'n do something because the selection returns only the cell from where the selection started.Can someone help me?

For mouse drag events to propagate to nodes other than the node in which the drag initiated, you need to activate a "full press-drag-release gesture" by calling startFullDrag(...) on the initial node. (See the Javadocs for MouseEvent and MouseDragEvent for details.) Then you can register for MouseDragEvents on the table cells in order to receive and process those events.
Here's a simple example: the UI is not supposed to be ideal but it will give you the idea.

How do i select multiple cells in numbers or iPad?

Hello,
can you help me? I do not find out how to select multiple cells in a table that do not stand next to each other.
For example, I want to select cells A1, A3, A9 and so on. Afterwards I want to change the colour.
Do you have an idea? Perhaps it's quite simple but I don't find the solution
Sorry, I'm no native english speaker. I hope you'll understand what I am looking for.

HI Ritscho
I do not beleive this is possible, I can see other threads here from 2 years ago asking the same thing and none of them have answers.
You can selesct a range of adjacent cells as Eric said, but not 2 different ranges. I usually use numbers on the iPad for filling in template spreadsheets that I create on my Mac. Most of the formatting I do on the Mac then fill in the blanks whilst i'm out and about.
Not the answer you were looking for but hope it helps.

When selecting one cell, multiple cells highlight

When I am working with Excel 2010, I try to select a single cell however multiple cells get highlighted. It will highlight usually the next 5-6 cells in the same row. It occurs randomly on random cells, but happens about 25% of the time. If I click the
cell and it does its highlighting thing, I usually have to click away in another cell and then re-click the first one to get it to go away. Also, if I just try to ignore the highlighted cells and try to work as normal, when I try to tab to the next cell in
the row, it will only let me tab between the cells in the column that are highlighted. It is not a mouse problem, I am not accidentally selecting multiple cells, and it happens on documents I created as well as documents others have created. It will also happens
on a new, blank document or others completely stripped of any kind of potentially hidden formatting. I have not tried to re-install Office yet, but that will be next step if no one has a solution. Thanks

I ran into this problem today working in Excel 2010 at 90% zoom.
First I tried F8 and Shift+F8 but neither of them worked.
Next I changed the zoom levels up and down and this worked while I was at a different zoom level than the document was saved in but went back to the same problem when I tried working at 90% zoom again.
Finally I came across the fix mentioned below from July 2, 2012 that suggested switching from Normal View to Page and then to Print view and back to Normal and this worked!!! Thanks to all for your input below, you saved my Monday morning!
LIST OF POSSIBLE FIXES:
1. Try using the F8 and/or Shift+F8 [extend selection] to toggle back and forth.
2. Change zoom level of your document up or down [this was only a temporary fix for me].
3. Change page layout between Normal, Page Layout, and Page Break Preview (the 3 boxes at the bottom right hand corner of excel spreadsheet) then back to Normal.

How do you format cell size in numbers for multiple cells at the same time?

How do you format the cell size of multiple cells at once in numbers?

select the cells you want to format by clicking at the top-left most cell, then shift click the bottom-right most cell.
Then open the inspector by selecting the menu item "View > Show Inspector", then click the table inspector segment:
now use the row height and column width fields to adjust as needed.
You can also select multiple rows and columns by clicking in an active tables row/column header, then dragging to select rows (or column), then hover the cursor on the line the separates rows (or columns) until the cursor changes to a bar with arrows, then click, hold, and drag as needed.

Trying to get multiple cell values within a geometry

I am provided with 3 tables:
1 - The GeoRaster
2 - The geoRasterData table
3 - A VAT table who's PK is the cell value from the above tables
Currently the user can select a point in our application and by using the getCellValue we get the cell value which is the PK on the 3rd table and this gives us the details to return to the user.
We now want to give the worst scenario within a given geometry or distance. So if I get back all the cell values within a given geometry/distance I can then call my other functions against the 3rd table to get the worst scores.
I had a conversation open for this before where JeffreyXie had some brilliant input, but it got archived while I was waiting on Oracle to resolve a bug (about 7 months)
See:
Trying to get multiple cell values within a geometry
If I am looking to get a list of cell values that interact with my geometry/distance and then loop through them, is there a better way?
BTW, if anybody wants to play with this functionality, it only seems to work in 11.2.0.4.
Below is the code I was using last, I think it is trying to get the cell values but the numbers coming back are not correct, I think I am converting the binary to integer wrong.
Any ideas?

Hey guys,
Zzhang,
That's a good spot and as it happens I spotted that and that is why I am sure I am querying that lob wrong. I always get the a logic going past the total length of the lob.
I think I am ok using 11.2.0.4, if I can get this working it is really important to us, so saying to roll up to 11.2.0.4 for this would be no problem.
The error in 11.2.0.3 was an internal error: [kghstack_underflow_internal_3].
Something that I think I need to find out more about, but am struggling to get more information on is, I am assuming that the lob that is returned is all cell values or at lest an array of 4 byte (32 bit) chunks, although, I don't know this.
Is that a correct assumption or is there more to it?
Have either of you seen any documentation on how to query this lob?
Thanks

Assign several classes to multiple cells in a table?

Hello,
I've searched this forum and the Internet for hours, but haven't been able to find a solution for this very basic problem. I'm editing a large table with CSS class="basicTable" assigned to it. In my stylesheet there are two classes for cell properties:
num for cells that contain a number
alt for cells with an alternative background colour
I would now like to assign both classes to a group of cells <td class="num alt">...</td>, but not to the complete table. Is there any way to do this other than editing each individual cell? When I select one cell, I can edit the CSS class in the Tag Inspector. When I select multiple cells, all I see in the Tag Insector is the CSS class for the whole table, not for the cells I have selected.
I am editing several large tables each with up to 10 columns and 20 rows, some cells of which are merged. It is really time-consuming to go through each cell individually.
Has anybody ever encountered this issue?

Copy-Paste Multiple Cells in Cell Editor in BI7 at once

Dear all
I am using Cell Editor in Query Designer (BI7.0).
There are around 200 Rows. And each Cell has got some specific restriction.
Now, I need to copy a complete column to another column - so all restrictions/formulas of all cells in that column need to get copied to another cell of next column.
I am able to copy single cell by cell. But, I want to copy the entire column at once and paste it (For example select multiple cells and paste).
Is it feasible? I am unable to do this.
Plz help.
Thanks
Partho Bardhan

You need to report it to Apple Feedback so it can be logged and put in the queue to be fixed.
http://www.apple.com/feedback/macosx.html
As a alternative you might check out Yoink in the Mac App Store (MAS). When you drag a item, a shelf will slide out on the side of the monitor. You drop the items on the shelf, navigate to the destination then drag item to new location. Fast and simple to use.

How can I preserve row and column addresses on multiple cells at once in Numbers?

How can I preserve row and column addresses on multiple cells at once in Numbers 3.2.2? I do a lot of rearranging and sorting and want to reference cells in other sheets. After entering the formulas (example: '=Sheet1::Table 1::H126') I will sort the table and the formulas will not move with the sort. I think I can fix this by going cell by cell checking the 'preserve row' and 'preserve column' boxes when editing the formula. I want to avoid having to go one by one. I know that checking the boxes creates a formula like this: '=Sheet1::Table 1::$H$126' I have also tried entering this manually and filling down but it doesn't include the preservations (the $$) in the autofill. If there is another way to remedy my sorting problem that would also be welcomed!
THANKS!!

The title of the post is this
How can I preserve row and column addresses on multiple cells at once in Numbers?
I restated the Question as follows
Can "Preserve Row" an / or "Preserve Column" be set on multiple cells at the same time.
In both cases it is not asked if multiple cells can be set to....
That is a given.
Step back a second... It is like selecting multiple cells and setting the text color of the currently selected cells to red. This can be done. More than one cell at a time modified because they are currently selected.
Whats is being asked is: if more than one cell is selected at the same time can the settings "Preserve Row" an / or "Preserve Column" be applied. No table I put up will help with that question.
YES or NO
If YES how?
