I want to programmatically deselect a row in JTable. Basically I have cehckbix in my jtable and my row needs to be selected or highlited when I click on checkbox. CLicking in any other column should not highlight the row.
I tries table.removeRowSelectionInterval(row,row) on clicking in cell other than checkbox it did not work.
I tried ListSelectionModelk.clearSelection() and then adding RowSelectionInterval() for rows as needed, it works but it interfere with some other functionality.
So I can't use this.
As #Nizil commented that you can write your own Cell Renderer or Cell Renderer
You also need to look at How to use Tables and How to use CheckBoxes

I want to be able to have a checkbox on the action column of every rows of data display.
Code
This is my code. The problem is that the checkbox is creating its own row at the bottom of the row that i want it to be at. What should i do, so that the checkbox is at the same row as "raise it up"?
We have one requirement in SSRS where we need to display the tablix on click of the Image. By default tablix will be hidden, when user clicks on the Image then we need to show the hidden tablix. Kindly suggest some solution if any. Thanks.
You can toggle the visibility of an object. Initially have the visibility property set to hidden, then use the toggleitem property to accomplish what you are looking for. Instructions are below
To hide static rows in a table, matrix, or list:
In report design view, click the table, matrix, or list to display
the row and column handles.
Right-click the row handle, and then click Row Visibility. The Row Visibility dialog box opens.
To set the visibility, follow steps 3 and 4 in the first procedure.
To hide static columns in a table, matrix, or list
In Design view, select the table, matrix, or list to display the row and column handles.
Right-click the column handle, and then click Column Visibility.
In the Column Visibility dialog box, follow steps 3 and 4 in the first procedure.
Then use the ToggleItem property of the table. Select the table, locate the property in the Properties window and specify the name of the textbox. If you now render the report you'll notice a little + icon in front of the testingBox content.
To find out what your textbox is called first select that and look at the bold part in top of the Properties window. To change it you can use the Name property. It's advisable to give it a clear name so you can easily locate it.
what i am trying to achieve is to have data populate a datagrid from a query, this part works fine. but once the data has been populated i want to add an additional row which the user will be able to type into. so for example the grid will have 5 pre populated rows and then the 6th row will be empty cells which the user can edit. the final column of this row will either be a button or an image with the click property set. this will be used to run an update query to update the dataprovider of the datagrid.
This is pretty easy. Just add a new object in your List that is bound to the datagrid. For the final column you will need an item renderer.
Ex:
dataGrid.dataProvider = someList;
//later when it is populated
someList.addItem(new Item());
After this you can set the focus to the desired column and the last row to show its input time.
You can also remove the last added item from the list to simulate a cancel action.
You will also need to set the 'editable' property of the grid to true. Set the selectionMode property to 'singleRow' Each column also has an individual 'editable' property so you can limit users to only changing certain properties.
As long as the data is simple text the default item editor (which is a textInput) will work fine. If you use an advancedDataGrid you can also include things like checkBoxes for Boolean data.
I'm trying to add an OR feature in the Continuous Filter Form and as you can see the first combobox shows up which I don't want it to show. Ideally, it should show only when the user wants the second row search option not in the first row filter. I have only OR in the combobox. Thanks for your help and let me know if you need any clarification!
Continuous form controls are all or nothing. If it's visible, it's visible in all rows, if invisible, it's invisible in all rows. There's nothing you can do about that.
You have four options (in order of complexity):
First Option:
The "On Current" event of the form happens when a user moves from one row to another inside the continuous form. you can add an IF statement to that event that disables the first box if the user has moved to the first row.
Second Option:
Have a fixed amount of filter boxes, and don't let the user pass the limit
Third Option:
Have a fixed amount of filter boxes, but make a "forward" and "back" buttons that will change what data the filter boxes link to, effectively making a 'custom' continuous form
Fourth Option:
Dynamically create the textboxes programatically (not recommended)
Set the default 'Visible' property to 'No' and then Reset it to 'Yes' when a second criteria is selected. This will populate the whole column though, just so you know.
I have a table column that I'm overriding the DefaultCellRenderer to display an icon.
Is there a way I could detect double-clicks on a JTable cell, so I can toggle the corresponding row value's state so that it changes the icon between two values (representing "off" and "on")?
There's two ways:
1) The easier way: Attach a mouse listener to the table, listen for a double click, find the row and column by rowAtPoint/columAtPoint, chenge the value, and call fireCellChanged() in the table model.
2) The harder (but slightly better) way: Have a custom cell editor that upon editing, changes the value, and calls stopCellEditing().
You don't need to do both.
Check this out as well, which does similar but with a button:

When you perform a single click, the cell rendered is replaced by the cell editor, so provide also a cell editor with same appearance than the rendered, add a mouse listener and capture the double-click and perform any desired action. When you finish invoke stopCellEditing().
