Struct gtk4::CellView[][src]

pub struct CellView(_);
Expand description

A widget displaying a single row of a GtkTreeModel

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.

Implementations

Creates a new CellView widget.

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.

area

the CellArea to layout cells

context

the CellAreaContext in which to calculate cell geometry

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].

markup

the text to display in the cell view

Returns

A newly created CellView widget.

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

text

the text to display in the cell view

Returns

A newly created CellView widget.

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

texture

the image to display in the cell view

Returns

A newly created CellView widget.

Creates a new builder-pattern struct instance to construct CellView objects.

This method returns an instance of CellViewBuilder which can be used to create CellView objects.

Returns a TreePath referring to the currently displayed row. If no row is currently displayed, None is returned.

Returns

the currently displayed row or None

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

Returns

whether self draws all of its cells in a sensitive state

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

Returns

whether self requests space to fit the entire TreeModel.

Returns the model for self. If no model is used None is returned.

Returns

a TreeModel used or None

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.

path

a TreePath or None to unset.

Sets whether self 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.

draw_sensitive

whether to draw all cells in a sensitive state.

Sets whether self 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.

fit_model

whether self should request space for the whole model.

Sets the model for self. If self already has a model set, it will remove it before setting the new model. If model is None, then it will unset the old model.

model

a TreeModel

The CellArea rendering cells

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

since 3.0

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).
