An interface for packing cells
- Module available since Gtk+ version 2.4

Synopsis |

|
|
|
Detail
|
|
CellLayout is an interface which is implemented by all objects which
provide a TreeViewColumn API for packing cells, setting attributes and data funcs.

Methods
|
|
cellLayoutPackStart |
:: (CellLayoutClass self, CellRendererClass cell) | | => self | | -> cell | cell - A CellRenderer.
| -> Bool | expand - True if cell is to be given extra space
allocated to cellLayout.
| -> IO () | | Packs the cell into the beginning of the cell layout. If expand is
False, then the cell is allocated no more space than it needs. Any
unused space is divided evenly between cells for which expand is True.
Note that reusing the same cell renderer is not supported.
|
|
|
cellLayoutPackEnd |
:: (CellLayoutClass self, CellRendererClass cell) | | => self | | -> cell | cell - A CellRenderer.
| -> Bool | expand - True if cell is to be given extra space
allocated to cellLayout.
| -> IO () | | Adds the cell to the end of cellLayout. If expand is False, then
the cell is allocated no more space than it needs. Any unused space is
divided evenly between cells for which expand is True.
Note that reusing the same cell renderer is not supported.
|
|
|
cellLayoutReorder |
:: (CellLayoutClass self, CellRendererClass cell) | | => self | | -> cell | cell - A CellRenderer to reorder.
| -> Int | position - New position to insert cell at.
| -> IO () | | Re-inserts cell at position. Note that cell has already to be
packed into cellLayout for this to function properly.
|
|
|
cellLayoutClear :: CellLayoutClass self => self -> IO () |
Remove all renderers from the cell layout.
|
|
cellLayoutSetAttributes |
:: (CellLayoutClass self, CellRendererClass cell, TreeModelClass (model row), TypedTreeModelClass model) | | => self | | -> cell | cell - A CellRenderer.
| -> model row | model - A model containing rows of type row.
| -> (row -> [AttrOp cell]) | Function to set attributes on the cell renderer.
| -> IO () | | Specify how a row of the model defines the
attributes of the CellRenderer cell. This is a convenience wrapper
around cellLayoutSetAttributeFunc in that it sets the cells of the cell
with the data retrieved from the model.
- Note on using TreeModelSort and
TreeModelFilter: These two models
wrap another model, the so-called child model, instead of storing their own
data. This raises the problem that the data of cell renderers must be set
using the child model, while the TreeIters that the view works with refer to
the model that encapsulates the child model. For convenience, this function
transparently translates an iterator to the child model before extracting the
data using e.g. treeModelSortConvertIterToChildIter.
Hence, it is possible to install the encapsulating model in the view and to
pass the child model to this function.
