Auto resize columns by double clicking on column boundry is not working some time [message #1385829]

Hello All,

We have migrated our Table Viewer in to NatTable successfully. After some random steps (like resize column, sorting, closing view) the autoresize by clicking on the column boundry is not woking. We are using the Composite layer and register the below command:
compositeLayer.registerCommandHandler(new AutoResizeColumnCommandHandler(
compositeLayer, bodyLayer));
We have debug this issue and we found out the problem as:
In DragModeEventHandler: mouseUp() One condition is added
if (startCol == col && startRow == row) {
parentModeEventHandler.mouseUp(event);
}
Here this condition fails for (startCol == col). The "col" is return as the column position of the column where releasing the mouse.

We didn't found the reason behind it.

Please let me know if anybody having the solution for this issue.

The issue you are describing is that you are moving the mouse on clicking. Therefore the drag mode is activated. I'm not sure if there is a solution for this. How should be checked that you are trying to perform a double click when moving the mouse while the mouse button is down?

Hi Dirk,

The actual problem is NatTable not allows column resizing some times and columns get freeze, in that case we have to restart the application to make it again work.

What we found is when resize column command not fire, the issue comes. Reason can be in mouseUp method in DragModeEventHandler class, below condition not executed when column resize fails, because both mouse events provide different column number.
if (startCol == col && startRow == row) {
parentModeEventHandler.mouseUp(event);
}
In this case startCol and col values are different. We have taken an example given in NatTable examples plugin and implemented it in viewpart and it also shows the same issue. Column get freeze in some scenarios. But we are not able to recognize the exact steps for the same and the issue is coming randomly

Could you please help us and let us know if any workaround available for this issue?

You ask for a workaround for a bug that is not exactly reproducible?

I never heard of such a bug, therefore I don't know a workaround. Please open a ticket, I will see when I'm able to take a look.

The code you are referring doesn't seem to me to be the cause as this is the code to trigger a mouse click rather than the drag operation.

Hi,

I came across the fact that the same question was asked in the SourceForge version. I thought the forum there was made readonly two years ago.

I didn't asked which version you are using, but if you really using the SourceForge version you may have several issues. Me moved from SourceForge to Eclipse about two years ago. The version 2.3.2 is therefore quite old and contains several bugs that have been already fixed in the current Eclipse version which is 1.1.0 atm.

I really recommend to update to the Eclipse version if you haven't done already. There are a lot of improvements and fixes since the 2.3.2 SourceForge version!

Greez,
Dirk
