GtkTreeview在列编辑时发出哪个信号？

Question

编辑可编辑列时，GtkTreeView会发出哪个信号？我想用回调函数捕获编辑。

Answer 1

我在树视图中使用以下代码（c ++）捕获编辑内容：

treeview.get_column_cell_renderer(col_index)->signal_editing_started().connect(
    sigc::mem_fun(*this, &YourClass::onEditingStarted));

回调是：

void YourClass::onEditingStarted(Gtk::CellEditable* editable, const Glib::ustring& path) {
    // here I'll connect an event to catch when the edition ends
    // YourClass::onEditingEnded has no parameters
    editable->signal_editing_done().connect(
        sigc::mem_fun(*this, &YourClass::onEditingEnded));
}
