If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

Detecting mouse clicks in editable cell of JTable

Hi everyone :)
I thought that this question might have been asked before, but I have searched the forums extensively and have not been able to find the solution.
What I want to achieve is to detect single and double mouse clicks on JTable cells (that are editable).
For example, I have a JTable and there exists within it an editable cell. If the user clicks on it once then that cell goes into edit mode, and the user can type directly into the cell. I have already successfully implemented this.
However, what I also want to do is detect a double-click so that I can pop up a dilaog that shows a list of default values that the user can select.
So here is what I want;
1. User clicks on the cell once.
2. Cell moves into edit mode.
3. If the user clicks again within a certain time interval then cancel edit mode and pop up a dialog containing values that the user can select from.
I think that to do this I need to be able to detect mouse clicks on the cell that is currently being edited. So far I have been unable to discover how this is done. I have even tried extending JTextField to get what I want, but with no luck.
Any help would be greatly appreciated.
Kind regards,
Ben Deany

Thanks for the reply.
Unfortunately, it is not possible to call 'AddMouseListener()' on a cell editor. You are only able to call 'addCellEditorListener()' and that only allows two events to the broadcast (edit cancel, and edit stop).

aamir

Hi Gorge,
Are you sure the column you are accessing is of type EditText ?
Please step through your code and do check the type of the column first.
While Rows <= index
Dim o = omatrix.Columns.Item("2000002049").Type 'Check the type here first.
edit1 = oMatrix.Columns.Item("2000002049").Cells.Item(index).Specific
index = index + 1

JTable JCombox popup on click in table cell

What is the recommended way of making a JComboBox that is in a JTable cell popup when the user clicks once anywhere in the cell?
The popup is actually a calendar that works fine if the user clicks on the spot where the button shows up in the cell but sets the focus in the text box of the JComboBox is the click is anywhere else in the cell and the popup doesn't sho in that case. To get to the popup requires a click on the button.

import java.awt.*;
import java.awt.event.*;

COLOUR TABLE CELLS

Hello,
I'm relatively new to the Contribute system, so apologies if
this topic has already been raised and answered (though I couldn't
find anything by searching).
I'm creating a website for a new client and they want an
editable calendar which I've created using a table with multiple
cells - a link here...
http://www.villapomba.com/test/availability_08.html
- How can I set up Contribute so that my client can colour the
cells as dates become booked?
I would appreciate any help.
Many thanks in advance.

1. start Contribute, connect
2. go to the page, Edit Page
3. place your cursor in the cell where the background color
has to change
4. right mouse click, choose Table Cell properties

How to distinguish is cell get key event or mouse event in table?

Hi!
I have a JTable.
1.Select cell and double click. As result caret is show
2.Select cell and start type. As result caret is show
How distinguish is caret is show, because cell get mouse event or key event?
Thank you.

Hm ...
the problem with the key events is, that they are partically taking place in an editor component - but the double click of the mouse clicked on a cell, which is not currently edited, can be get by a MouseListener added to the JTable.
My idea to that is as follows - hold the double_clicked state in a boolean variable hold by your JTable subclass - it is set by a MouseListener added to the JTable - and reset by the overwritten prepareEditor(...) method. This method should do the following:
// say, double_clicked is a boolean field in your JTable subclass
public Component prepareEditor(TableCellEditor editor,int row,int column) {
Component c = super.prepareEditor(editor,row,column);
if ((!double_clicked)&&(c instanceof JTextField)) { ((JTextField) c).setText(""); }
double_clicked = false;
return c;
}now you have only to implement an add a MouseListener to your JTable subclass which detects this double click and sets the double_clicked field accordingly.
This is an idea on the fly - hope it is helpful for you.

Table cell shifting issue

Getting a wierd within-cell selection indicator shift effect when using tables in LV 2013(32) on Win 7 (64).   Hestitate to call it a "scroll" 'cause that has other meanings in the table context.
Click on the letters in the attached VI to see it -- same effects if the table is in a running VI or not.
          + clicking on "A" does nothing. Deleting "A" causes the cell to shift.
          + clicking on any of the cells below "A" act like the above
          + clicking on header cell "x" causes a big sideways shift. Putting other values in the cell has other effects (some shift a lot, some not at all)
          + clicking on table cell "y" causes a big sideways shift. Putting other values in the cell has other effects (some shift a lot, some not at all)
          + clicking on table cell "z" does not shift. Deleting "z" causes a big sideways shift
          + I noticed the shift that happens when you delete "A" stops at the same horizontal location as if you
Observations:
    + Appears to be tied to cell's justify=center.
          + Shifting is always is right-to-left.
          + I noticed the shift that happens when you delete "A" stops at the same horizontal location as if you click on "y"
          + occurs on at least two different machines from different mfg's. Both running 2013-32 on Win7-64.

That's it! Thanks for tying up a loose end on an old thread.
With this information I was able to recreate this in LV2014-32 on Win7-64 so it's still a bug.
The key is the table has to span quadrant 3&4 of the front panel.
Drop a table control with (left,top)=(-108,185) for instance and (width,height)=(250,169). Select the entire table and set justification=center. The first column whose center is to the right of the front panel's "y axis" will have centering issues. Move the table off the y axis and the issue goes away. Move it back and issue comes back.
Having left or right justified prevents the issue but this is a Band-aid, not a fix, and was not applicable in my case as my UI needed centered text or it would look funny. I was using the table to display info and allowing the user to click on a cell to select it, at which point I would change the color via property node. My workaround was to change control focus immediately after the mouse click to minimize the time the drifting cell was noticeable.

Can spark datagrid mouse click be disabled while in a custom item editor?

Hi,
Is it possible to prevent a user from clicking on another cell in a datagrid until the cell currently being edited has had its data saved?
I would like to validate the cell's text data as it is being entered by a user, character by character. If the validation fails, I would like to put up an error message and prevent the user from clicking outside of the cell. I am able to validate the data and put up an error message. But I have not found a way, if there is one, of disabling mouse clicks in other cells. I've tried setting the IE's parent.editable, .enabled and .mouseEnabled properties to false. But none of these are working for me.
Thanks,
-Adobegillisisle2

The session does stay if I hit the TAB or RETURN keys. I return false from my overridden save() function and the session stays keeping the user in the edit cell, allowing fixing the invalid data. But I don't get the same behavior when I click the mouse on another cell. In these cases, my save function is still called, and I still return false ( in the case where the validation fails ), but the edit session goes away.

SAP Portal development-Table Controls having link to table cell content

Hello all,
I am creating the SAP portal in which i am using Table controls to display the data. I want the function should be called whenever user clicks the table cell content. i.e. i want to create the function link to table cell.
Please reply soon.
Regards,
Prashant

Hi Prashant,
You haven't mentioned if you are using Webdynpro or HTMLB JSPDynPages.
If its the webdynpro, you can declare then and there itself that the content to the table column is a row my changing the property.
If it is a HTMLB component TableVIew that you are trying to use, you can include a TableCellRenderer Class which renders the cells of the table at the runtime as links or buttons or whatever you want to put.
So let me know, what exactly you are trying to use, then finding a solution will be more clear.

Sujana

JavaFX2.2 TableView:How to make a table cell be edited without mouse click?

Hi,
I've encounter a problem with editable table cells. I'm using the TableView in my project just as the Tutorial on Oracle (http://docs.oracle.com/javafx/2/ui_controls/table-view.htm).
According to it, I use the setCellFactory method to reimplement the table cell as a text field with the help of the TextFieldTableCell class. However, I found the steps is a little complex to get to the point where the cell can be edited:
1.Let the table cell be selected by using direction key.
2.Press “Enter” to converts the cell to a text filed so that it is ready to be edited.
3.Clicking in the text field allows the contents to be edited
The problem is step 3, that you must use the mouse to click before you can input data in this table cell.
So, is there a solution to avoid step 3? That is the text field allows the data inputting when you just press “Enter”(step 2).
By the way, English is not my native language. Hope I have made myself clear.

Hi,
You need to pass the focus to the text field when the startEditing event occurs. In the class that extends TableCell you use for cellFactory:
public void startEdit() {
super.startEdit();
createTextField();
setText(null);
setGraphic(textField);
* put focus on the textfield so user can directly typed on it
Runnable r = new Runnable() {
@Override
public void run() {
getGraphic().requestFocus();
Platform.runLater(r);
}

Multiple JButtons inside JTable cell - Dispatch mouse clicks

Hi.
I know this subject has already some discussions on the forum, but I can't seem to find anything that solves my problem.
In my application, every JTable cell is a JPanel, that using a GridLayout, places vertically several JPanel's witch using an Overlay layout contains a JLabel and a JButton.
As you can see, its a fairly complex cell...
Unfortunately, because I use several JButtons in several locations inside a JTable cell, sometimes I can't get the mouse clicks to make through.
This is my Table custom renderer:
public class TimeTableRenderer implements TableCellRenderer {
     Border unselectedBorder = null;
     Border selectedBorder = null;
     public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
               boolean hasFocus, int row, int column) {
          if (value instanceof BlocoGrid) {
               if (isSelected) {
                    if (selectedBorder == null)
                         selectedBorder = BorderFactory.createMatteBorder(2,2,2,2, table.getSelectionBackground());
                    ((BlocoGrid) value).setBorder(selectedBorder);
               } else {
                    if (unselectedBorder == null)
                         unselectedBorder = BorderFactory.createMatteBorder(2,2,2,2, table.getBackground());
                    ((BlocoGrid) value).setBorder(unselectedBorder);
          return (Component) value;
}and this is my custom editor (so clicks can get passed on):
public class TimeTableEditor extends AbstractCellEditor implements TableCellEditor {
     private TimeTableRenderer render = null;
     public TimeTableEditor() {
          render = new TimeTableRenderer();
    public Component getTableCellEditorComponent(JTable table, Object value,
            boolean isSelected, int row, int column) {
         if (value instanceof BlocoGrid) {
              if (((BlocoGrid) value).barras.size() > 0) {
                   return render.getTableCellRendererComponent(table, value, isSelected, true, row, column);
         return null;
    public Object getCellEditorValue() {
        return null;
}As you can see, both the renderer and editor return the same component that cames from the JTable model (all table values (components) only get instantiated once, so the same component is passed on to the renderer and editor).
Is this the most correct way to get clicks to the cell component?
Please check the screenshot below to see how the JButtons get placed inside the cell:

If you need more info, please say so.
Thanks.

My mistake... It worked fine. The cell span code was malfunctioning. Thanks anyway.

Right click table cell selection

I'm making a GUI interface including a table. What I'd like to implement is ability to right click on the cell and open the options selection, similar as to when right click the icon on the desktop. Any ideas ?

You will need to create the component that will show your options and then add a MouseListener to your table that detects the mouse event and shows your options.
A good place to start would be to have a look at this link: http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
And here: http://java.sun.com/docs/books/tutorial/uiswing/events/mouselistener.html

How do I click on a cell in a table control, and display the value in a string?

What I would like to do is to click on a cell in a table control, and have the value of the cell be displayed in a string indicator. What ever cell I click on, I would like the value to be displayed in the indicator.
Thank you!
