Gtk::TreeModelColumnRecord Class Reference
[TreeView Classes]
List of all members.
Detailed Description
Typedefed as TreeModel::ColumnRecord.
Keeps a record of TreeModelColumns. ColumnRecord objects are used to setup a new TreeModel (or rather, an implementation of the model, like Gtk::ListStore or Gtk::TreeStore). It is convenient to do that by deriving from TreeModel::ColumnRecord:
An instance of MyModelColumns
should be passed to ListStore::create() or TreeStore::create(). The members filename
, description
and thumbnail
can then be used with Gtk::TreeRow::operator[]() to specify the column you're interested in.
Neither TreeModel::ColumnRecord nor the TreeModelColumns contain any real data -- it's merely a description of what type is stored in which column of a TreeModel. Thus it's absolutely legal to use a statically allocated TreeModel::ColumnRecord (as long as you make sure it's instantiated after Gtk::Main), even when creating multiple models from it.

Adds a TreeModelColumn to this record.
add() not only registers the column, but also assigns a column index to it. Once registered, the TreeModelColumn is final, and you're free to pass it around by value. |
