GI.Gtk.Objects.CellView

A CellView displays a single row of a TreeModel using a CellArea and CellAreaContext. A CellAreaContext can be provided to the CellView at construction time in order to keep the cellview in context of a group of cell views, this ensures that the renderers displayed will be properly aligned with each other (like the aligned cells in the menus of ComboBox).

CellView is Orientable in order to decide in which orientation the underlying CellAreaContext should be allocated. Taking the ComboBox menu as an example, cellviews should be oriented horizontally if the menus are listed top-to-bottom and thus all share the same width but may have separate individual heights (left-to-right menus should be allocated vertically since they all share the same height but may have variable widths).

CSS nodes

GtkCellView has a single CSS node with name cellview.

getDisplayedRow

cellViewGetDisplayedRow

Arguments

:: (HasCallStack, MonadIO m, IsCellView a)

=> a

cellView: a CellView

-> m (Maybe TreePath)

Returns: the currently displayed row or Nothing

Returns a TreePath referring to the currently displayed row. If no row is currently displayed, Nothing is returned.

getDrawSensitive

cellViewGetDrawSensitive

Arguments

:: (HasCallStack, MonadIO m, IsCellView a)

=> a

cellView: a CellView

-> m Bool

Returns: whether cellView draws all of its cells in a sensitive state

Gets whether cellView is configured to draw all of its cells in a sensitive state.

getFitModel

cellViewGetFitModel

Arguments

:: (HasCallStack, MonadIO m, IsCellView a)

=> a

cellView: a CellView

-> m Bool

Returns: whether cellView requests space to fit the entire TreeModel.

Gets whether cellView is configured to request space to fit the entire TreeModel.

getModel

cellViewGetModel

Arguments

:: (HasCallStack, MonadIO m, IsCellView a)

=> a

cellView: a CellView

-> m (Maybe TreeModel)

Returns: a TreeModel used or Nothing

Returns the model for cellView. If no model is used Nothing is returned.

new

cellViewNew

Arguments

:: (HasCallStack, MonadIO m)

=> m CellView

Returns: A newly created CellView widget.

Creates a new CellView widget.

newWithContext

cellViewNewWithContext

Arguments

:: (HasCallStack, MonadIO m, IsCellArea a, IsCellAreaContext b)

=> a

area: the CellArea to layout cells

-> b

context: the CellAreaContext in which to calculate cell geometry

-> m CellView

Returns: A newly created CellView widget.

Creates a new CellView widget with a specific CellArea to layout cells and a specific CellAreaContext.

Specifying the same context for a handful of cells lets the underlying area synchronize the geometry for those cells, in this way alignments with cellviews for other rows are possible.

newWithMarkup

cellViewNewWithMarkup

Arguments

:: (HasCallStack, MonadIO m)

=> Text

markup: the text to display in the cell view

-> m CellView

Returns: A newly created CellView widget.

Creates a new CellView widget, adds a CellRendererText to it, and makes it show markup. The text can be marked up with the [Pango text markup language][PangoMarkupFormat].

newWithText

cellViewNewWithText

Arguments

:: (HasCallStack, MonadIO m)

=> Text

text: the text to display in the cell view

-> m CellView

Returns: A newly created CellView widget.

Creates a new CellView widget, adds a CellRendererText to it, and makes it show text.

newWithTexture

cellViewNewWithTexture

Arguments

:: (HasCallStack, MonadIO m, IsTexture a)

=> a

texture: the image to display in the cell view

-> m CellView

Returns: A newly created CellView widget.

Creates a new CellView widget, adds a CellRendererPixbuf to it, and makes it show texture.

setDisplayedRow

cellViewSetDisplayedRow

Arguments

:: (HasCallStack, MonadIO m, IsCellView a)

=> a

cellView: a CellView

-> Maybe TreePath

path: a TreePath or Nothing to unset.

-> m ()

Sets the row of the model that is currently displayed by the CellView. If the path is unset, then the contents of the cellview “stick” at their last value; this is not normally a desired result, but may be a needed intermediate state if say, the model for the CellView becomes temporarily empty.

setDrawSensitive

cellViewSetDrawSensitive

Arguments

:: (HasCallStack, MonadIO m, IsCellView a)

=> a

cellView: a CellView

-> Bool

drawSensitive: whether to draw all cells in a sensitive state.

-> m ()

Sets whether cellView should draw all of its cells in a sensitive state, this is used by ComboBox menus to ensure that rows with insensitive cells that contain children appear sensitive in the parent menu item.

setFitModel

cellViewSetFitModel

Arguments

:: (HasCallStack, MonadIO m, IsCellView a)

=> a

cellView: a CellView

-> Bool

fitModel: whether cellView should request space for the whole model.

-> m ()

Sets whether cellView should request space to fit the entire TreeModel.

This is used by ComboBox to ensure that the cell view displayed on the combo box’s button always gets enough space and does not resize when selection changes.

setModel

cellViewSetModel

Arguments

:: (HasCallStack, MonadIO m, IsCellView a, IsTreeModel b)

=> a

cellView: a CellView

-> Maybe b

model: a TreeModel

-> m ()

Sets the model for cellView. If cellView already has a model set, it will remove it before setting the new model. If model is Nothing, then it will unset the old model.

Properties

cellArea

The CellArea rendering cells

If no area is specified when creating the cell view with cellViewNewWithContext a horizontally oriented CellAreaBox will be used.

since 3.0

constructCellViewCellArea :: (IsCellView o, MonadIO m, IsCellArea a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “cell-area” property. This is rarely needed directly, but it is used by new.

getCellViewCellArea :: (MonadIO m, IsCellView o) => o -> m (Maybe CellArea)

Get the value of the “cell-area” property. When overloading is enabled, this is equivalent to

get cellView #cellArea

cellAreaContext

The CellAreaContext used to compute the geometry of the cell view.

A group of cell views can be assigned the same context in order to ensure the sizes and cell alignments match across all the views with the same context.

ComboBox menus uses this to assign the same context to all cell views in the menu items for a single menu (each submenu creates its own context since the size of each submenu does not depend on parent or sibling menus).

since 3.0

constructCellViewCellAreaContext :: (IsCellView o, MonadIO m, IsCellAreaContext a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “cell-area-context” property. This is rarely needed directly, but it is used by new.

getCellViewCellAreaContext :: (MonadIO m, IsCellView o) => o -> m (Maybe CellAreaContext)

Get the value of the “cell-area-context” property. When overloading is enabled, this is equivalent to

get cellView #cellAreaContext

drawSensitive

Whether all cells should be draw as sensitive for this view regardless of the actual cell properties (used to make menus with submenus appear sensitive when the items in submenus might be insensitive).

since 3.0

constructCellViewDrawSensitive :: (IsCellView o, MonadIO m) => Bool -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “draw-sensitive” property. This is rarely needed directly, but it is used by new.

Get the value of the “draw-sensitive” property. When overloading is enabled, this is equivalent to

get cellView #drawSensitive

setCellViewDrawSensitive :: (MonadIO m, IsCellView o) => o -> Bool -> m ()

Set the value of the “draw-sensitive” property. When overloading is enabled, this is equivalent to

set cellView [ #drawSensitive := value ]

fitModel

Whether the view should request enough space to always fit the size of every row in the model (used by the combo box to ensure the combo box size doesn't change when different items are selected).

since 3.0

set cellView [ #fitModel := value ]

model

The model for cell view

since 2.10

clearCellViewModel :: (MonadIO m, IsCellView o) => o -> m ()

Set the value of the “model” property to Nothing. When overloading is enabled, this is equivalent to

clear #model

Construct a GValueConstruct with valid value for the “model” property. This is rarely needed directly, but it is used by new.

getCellViewModel :: (MonadIO m, IsCellView o) => o -> m (Maybe TreeModel)

get cellView #model

setCellViewModel :: (MonadIO m, IsCellView o, IsTreeModel a) => o -> a -> m ()

Set the value of the “model” property. When overloading is enabled, this is equivalent to

set cellView [ #model := value ]
