alias Gtk::TreeCellDataFunc
Overview
A function to set the properties of a cell instead of just using the straight mapping between the cell and the model.
This function is useful for customizing the cell renderer. For example, a function might get an* integer from the tree_model, and render it to the “text” attribute of “cell” by converting it to its written equivalent.
