Question

Does anyone know how to clear/remove any existing freeze or split panes on a sheet with Apache POI?

I tried creating a new freeze pane at (-1,-1), but it appears POI will automatically change that to (0,0), which means that the first row and column are still frozen.

Fyi I’m using the HSSF and XSSF API’s.

Answer 1

Downloaded the new version (3.8 beta 3) and it looks like they’ve reconciled the problem. The row/column of the freeze pane isn’t frozen anymore (it use to be).

Now setting anything less than 0 will default to (0,0), but (0,0) does indeed turn off the freeze/split panes.. However, if no freeze pane currently exists (or if it’s already at (0,0)), then you’ll get an IndexOutOfBoundsException.

try
{
    sheet.createFreezePane(0,0);
}
catch(IndexOutOfBoundsException e)
{
    System.out.println("previously didn't have a freeze pane.");
}
