Resizable DropDown Box in NatCombo [message #1773303]

I am using ComboBoxCellEditor in a NatTable and would like to resize the dropdown list at its borders (similar to windows). I can achieve this by extending NatCombo, overriding createDropdownControl(int style) and changing the line

 this.dropdownShell = new Shell(getShell(), SWT.MODELESS);

 this.dropdownShell = new Shell(getShell(), SWT.RESIZE);

Is it possible to do this wihtout overriding the method and copying the whole method body except that one line?

Is there a reason why the dropdownShell does not have a seperate style parameter/variable?

You checked the code already. So you already know that the answer to this question is No. Code never lies.

Nobody requested that feature in the last years or found a workaround that was never told us. Maybe it was used in the past with an older implementation to avoid some side effects or it was done because there was no reason seen for this. I can't tell.

If you want to make this configurable to avoid subclassing and overriding (which I definitely prefer), please create an enhancement ticket for this. And at best provide a patch via Gerrit.

P.S. Please ask questions on NatTable in the NatTable forum, so the NatTable users can benefit from your questions. Not sure how many of them are also checking the Nebula forum.
