[PATCH 1/4] gui: New type PsppireEmptyListStore.

[PATCH 1/4] gui: New type PsppireEmptyListStore. |
Date: |
Fri, 20 Apr 2012 22:11:52 -0700 |
PsppireEmptyListStore is an GtkTreeModel implementation that has a
client-specified number of rows and zero columns. It is a useful model for
GtkTreeView or PsppSheetView when the client can easily synthesize cell
data using a callback set with gtk_tree_view_column_set_cell_data_func().
In that situation, GtkListStore can be wasteful (because it uses a lot of
memory to store what does not need to be stored) and situation-specific
custom models require additional boilerplate.
This commit also modified the text data import dialog code to use
PsppireEmptyListStore. Future commits will add other users.
