@Generated("io.github.jwharm.JavaGI")
public class ColumnViewCell
extends ListItem

Represents items in a cell in ColumnView.

The GtkColumnViewCells are managed by the ColumnView widget (with its factory) and cannot be created by applications, but they need to be populated by application code. This is done by calling setChild(org.gnome.gtk.Widget).

GtkColumnViewCells exist in 2 stages:

1. The unbound stage where the listitem is not currently connected to an item in the list. In that case, the Gtk.ColumnViewCell:item property is set to null.

2. The bound stage where the listitem references an item from the list. The Gtk.ColumnViewCell:item property is not null.

Constructor Details

ColumnViewCell

public ColumnViewCell(MemorySegment address)

Create a ColumnViewCell proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ColumnViewCell

public ColumnViewCell()

Creates a new ColumnViewCell.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ColumnViewCell class

Returns:

the GType

asParent

protected ColumnViewCell asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class ListItem

getChild

public @Nullable Widget getChild()

Gets the child previously set via gtk_column_view_cell_set_child() or null if none was set.

Overrides:

getChild in class ListItem

Returns:

The child

Since:

4.12

getFocusable

public boolean getFocusable()

Checks if a list item has been set to be focusable via gtk_column_view_cell_set_focusable().

Overrides:

getFocusable in class ListItem

Returns:

true if the item is focusable

Since:

4.12

getItem

public @Nullable GObject getItem()

Gets the model item that associated with self.

If this ColumnViewCell is unbound, this function returns null.

Overrides:

getItem in class ListItem

Returns:

The item displayed

Since:

4.12

getPosition

public int getPosition()

Gets the position in the model that this ColumnViewCell currently displays.

If this ColumnViewCell is unbound, GTK_INVALID_LIST_POSITION is returned.

Overrides:

getPosition in class ListItem

Returns:

The position of this item

Since:

4.12

getSelected

public boolean getSelected()

Checks if the item is displayed as selected.

The selected state is maintained by the list widget and its model and cannot be set otherwise.

Overrides:

getSelected in class ListItem

Returns:

true if the item is selected.

Since:

4.12

setChild

public void setChild(@Nullable Widget child)

Sets the child to be used for this listitem.

This function is typically called by applications when setting up a listitem so that the widget can be reused when binding it multiple times.

Overrides:

setChild in class ListItem

Parameters:

child - The list item's child or null to unset

Since:

4.12

setFocusable

public void setFocusable(boolean focusable)

Sets this ColumnViewCell to be focusable.

If an item is focusable, it can be focused using the keyboard. This works similar to Widget.setFocusable(boolean).

Note that if items are not focusable, the keyboard cannot be used to activate them and selecting only works if one of the listitem's children is focusable.

By default, list items are focusable.

Overrides:

setFocusable in class ListItem

Parameters:

focusable - if the item should be focusable

Since:

4.12

builder

public static ColumnViewCell.Builder<? extends ColumnViewCell.Builder> builder()

A ColumnViewCell.Builder object constructs a ColumnViewCell with the specified properties. Use the various set...() methods to set properties, and finish construction with ColumnViewCell.Builder.build().

Returns:

the builder object
