I think this is a limitation in how Gorm decides whether or not to drop the formatter. Looking at DataPalette.m (https://github.com/gnustep/apps-gorm/blob/master/Palettes/4Data/DataPalette.m#L355) it checks whether the object at the drag destination responds to -setFormatter:, my expectation is that this would be NSTableView, NSScrollView or NSTableColumn when you drag over a table. It's the column's -dataCell that the formatter needs attaching to...does that need handling specially in DataPalette.m?
Thanks, Graham.

What I _think_ I should do is drag the number formatter avatar from the Gorm palette to the column, but that has no effect. Specifically, dragging the formatter onto most of the table's area shows the "no entry" cursor. If I drag it over the column headers, the cursor changes to the source/target overlapping rectangles, but dropping the formatter has no visible effect, and the document is not dirty (i.e. no changes were made). There's a workaround, in that I can do all this in code, but can I avoid that by using Gorm? Am I just holding it wrong? Thanks for your help, Graham. _______________________________________________ Discuss-gnustep mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnustep
