public class TreeListRow
extends GObject

GtkTreeListRow is used by GtkTreeListModel to represent items.

It allows navigating the model as a tree and modify the state of rows.

GtkTreeListRow instances are created by a GtkTreeListModel only when the Gtk.TreeListModel:passthrough property is not set.

There are various support objects that can make use of GtkTreeListRow objects, such as the TreeExpander widget that allows displaying an icon to expand or collapse a row or TreeListRowSorter that makes it possible to sort trees properly.

Constructor Details

TreeListRow

public TreeListRow(MemorySegment address)

Create a TreeListRow proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the TreeListRow class

Returns:

the GType

asParent

protected TreeListRow 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 GObject

getChildRow

public TreeListRow getChildRow(int position)

If this TreeListRow is not expanded or position is greater than the number of children, null is returned.

Parameters:

position - position of the child to get

Returns:

the child in position

getChildren

public ListModel getChildren()

If the row is expanded, gets the model holding the children of this TreeListRow.

This model is the model created by the Gtk.TreeListModelCreateModelFunc and contains the original items, no matter what value Gtk.TreeListModel:passthrough is set to.

Returns:

The model containing the children

getDepth

public int getDepth()

Gets the depth of this row.

Rows that correspond to items in the root model have a depth of zero, rows corresponding to items of models of direct children of the root model have a depth of 1 and so on.

The depth of a row never changes until the row is removed from its model at which point it will forever return 0.

Returns:

The depth of this row

getExpanded

public boolean getExpanded()

Gets if a row is currently expanded.

Returns:

true if the row is expanded

getItem

public GObject getItem()

Gets the item corresponding to this row,

Returns:

The item of this row. This function is only marked as nullable for backwards compatibility reasons.

getParent

public TreeListRow getParent()

Gets the row representing the parent for this TreeListRow.

That is the row that would need to be collapsed to make this row disappear.

If this TreeListRow is a row corresponding to the root model, null is returned.

The value returned by this function never changes until the row is removed from its model at which point it will forever return null.

Returns:

The parent of this TreeListRow

getPosition

public int getPosition()

Returns the position in the GtkTreeListModel that this TreeListRow occupies at the moment.

Returns:

The position in the model

isExpandable

public boolean isExpandable()

Checks if a row can be expanded.

This does not mean that the row is actually expanded, this can be checked with getExpanded().

If a row is expandable never changes until the row is removed from its model at which point it will forever return false.

Returns:

true if the row is expandable

setExpanded

public void setExpanded(boolean expanded)

Expands or collapses a row.

If a row is expanded, the model of calling the Gtk.TreeListModelCreateModelFunc for the row's item will be inserted after this row. If a row is collapsed, those items will be removed from the model.

If the row is not expandable, this function does nothing.

Parameters:

expanded - true if the row should be expanded

builder

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

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