Mouse wheel scroll on SortableTable selects rows

Postby aryanarvind » Thu Jul 23, 2020 7:27 am

Hello,

When you scroll within in the SortableTable using mouse wheel, the selection changes.
We have actions associated to selection change and when trying to just scroll through the table we wouldn't want to change selection but to just scroll as it's supposed to.
There are 2 problems here.
1. The mouse wheel moves the selection down.
2. The mouse wheel does not move the scroll bar down.

Please let me know if you want more details on the same.

Thanks & Regards,
Aravind Chennuru

I cannot reproduce this problem in the SortableTableDemo.java using mouse wheel. Just change the row count from 8 to a large number if you want to reproduce it yourself.

I am unable to launch the jide demos anymore.. the demo terminates, as soon as I launch it.. must be something to do with license?

You download the release package and run the example project from IDEA or Eclipse. You need to modify the code so of course the demo won't work.

Hello,

Thank you for the response. I managed to download the jide_demo.jar and copy the source code and run it from eclipse.
I realized that we are using a combination of table models.
1. SortableTableModel
2. FilterableTableModel
3. PaginationModel
The behavior of selecting the rows on mouse wheel happens on pageNavigationBar.
Is there a way to disable this feature on mouse wheel for PageNavigationBar?
As I mentioned the selection change triggers actions on various plugins and would be nice to have intentional selections like user clicks instead of Mouse Wheel when the user is just trying to scroll down to a specific region in a table.

Thanks & Regards,
Aravind Chennuru

That explained. You can override createMouseWheelListener to return a mouse wheel listener that does nothing to prevent it.

Hello,
In continuation, is this a bug with selection?
When I resize the table and scroll down, I see multi selection. which should not happen.
Please refer to the screenshot.

I ran your code but didn't notice any multiple selections. What exactly did you do? I select, resize, and wheel scroll.

Those are 2 different problems.
The code I sent reproduces the problem when I use mouse wheel the table does not scroll. This is using both sortableTable with PageNavigationBar.

The other one, we don't need a code, you can reproduce that in there...
1. Resize the table to get smaller.
2. Scroll in the table using mouse wheel
3. Resize the table to grow bigger.
4. You can see multiple selections.

Just remove the mouse wheel listener we added.

Code: Select all
            protected void initComponents() {
                 ...
                MouseWheelListener[] mouseWheelListeners = _sortableTable.getMouseWheelListeners();
                _sortableTable.removeMouseWheelListener(mouseWheelListeners[0]);
            }


I still don't see the second issue with or without the change I just mentioned. Please make sure it is not an issue because of your own code.

I am running it as a separate demo and I don't see the issue. Then I reproduce it using JideDemo and run as a nested demo. Do you see it in your real application?

I will fix it. If you want to fix it in your code for now, please override as below.

Code: Select all
            @Override
            protected void setSelectedRecordIndex(int row) {
                _sortableTable.getSelectionModel().clearSelection();
                _sortableTable.getSelectionModel().setSelectionInterval(row, row);
            }
