Description

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.

Types

class GObjectClass o => CellLayoutClass o Source

toCellLayout :: CellLayoutClass o => o -> CellLayout Source

Methods

cellLayoutPackStart Source

Arguments

:: (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 Source

Arguments

:: (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 Source

Arguments

:: (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 () Source

Remove all renderers from the cell layout.

cellLayoutClearAttributes Source

Arguments

:: (CellLayoutClass self, CellRendererClass cell)
=> self
-> cell	`cell` - A `CellRenderer` to clear the attribute mapping on.
-> IO ()

Clears all existing attributes previously set with cellLayoutSetAttributes.

cellLayoutGetCells Source

Arguments

:: CellLayoutClass self
=> self
-> IO [CellRenderer]	returns a list of cell renderers

Returns the cell renderers which have been added to cellLayout.

Available since Gtk+ version 2.12

cellLayoutAddColumnAttribute Source

Arguments

:: (CellLayoutClass self, CellRendererClass cell)
=> self
-> cell	`cell` - A `CellRenderer`.
-> ReadWriteAttr cell a v	`attribute` - An attribute of a renderer.
-> ColumnId row v	`column` - The virtual column of the model from which to retrieve the attribute.
-> IO ()

Adds an attribute mapping to the renderer cell. The column is the ColumnId of the model to get a value from, and the attribute is the parameter on cell to be set from the value. So for example if column 2 of the model contains strings, you could have the "text" attribute of a CellRendererText get its values from column 2.

cellLayoutSetAttributes Source

Arguments

:: (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.

cellLayoutSetAttributeFunc Source

Arguments

:: (CellLayoutClass self, CellRendererClass cell, TreeModelClass model)
=> self
-> cell	`cell` - A `CellRenderer`.
-> model	`model` - A model from which to draw data.
-> (TreeIter -> IO ())	Function to set attributes on the cell renderer.
-> IO ()

Install a function that looks up a row in the model and sets the attributes of the CellRenderer cell using the row's content.
