TreeModelFilterModifyFunc
Description:
[ CCode ( instance_pos = 4.9 ) ]
public delegate void TreeModelFilterModifyFunc (TreeModel model, TreeIter iter, out Value value, int column)
public delegate void TreeModelFilterModifyFunc (TreeModel model, TreeIter iter, out Value value, int column)
A function which calculates display values from raw values in the model.
It must fill value with the display value for the column column in the row indicated by iter.
Since this function is called for each data access, it’s not a particularly efficient operation.
Parameters:
| model |
the `GtkTreeModelFilter` |
| iter |
a `GtkTreeIter` pointing to the row whose display values are determined |
| value |
A `GValue` which is already initialized for with the correct type for the column |
| column |
the column whose display value is determined |
| data |
user data given to set_modify_func |
