Hi John, I replaced the PsppSheetView with GtkTreeView in the variables window to see how it looks. Basically it works but there are some differences in user interaction. The GtkTreeView expects a first click on the cell to select the cell and then another click to edit the cell. My implementation for the dialog windows for Type, Value Label and Missing is based on the row-activate signal and requires that one does a double click on the cell to open the dialog. This is then different compared to editing the text cells like NAME, where just one click to select and a second single click to start editing is required. It is possible to have the „activate“ also with just one click, but then this interferes with the selection process. Clicking on a TYPE cell to start the selection will open the dialog window. (See gtk_tree_view_set_activate_on_single_click in the data-editor.c changes) It is also possible to start editing with just one click by using the activate callback to do gtk_tree_view_set_cursor. However this also interferes with the selection process. (see on_row_activated ). I also thought about a new cell renderer for the dialog box type editing but the TYPE dialog box modifies data in several columns plus I am not too sure how I can end the editing inside the editing-started callback. Maybe this is not possible. Anyway, using the GtkTreeView in the way it is supposed to be used is different in the way the editing is activated. My ideas to start editing with just one click resulted in problems with the selection process. Here is a video link to see the GtkTreeView based behavior with lousy sound: https://youtu.be/4xS0Beb0Gdo Do you think we should change to GtkTreeView? Attached is the patch with my changes including debugging printfs. So if you want to try it… I did this on MacOS with gtk3 18.5.3 via macports. Friedrich
