Constructor Details

FlowBoxChild

public FlowBoxChild(MemorySegment address)

Create a FlowBoxChild proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

FlowBoxChild

public FlowBoxChild()

Creates a new FlowBoxChild.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the FlowBoxChild class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected FlowBoxChild 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 Widget

changed

public void changed()

Marks this FlowBoxChild as changed, causing any state that depends on this to be updated.

This affects sorting and filtering.

Note that calls to this method must be in sync with the data used for the sorting and filtering functions. For instance, if the list is mirroring some external data set, and two children changed in the external data set when you call gtk_flow_box_child_changed() on the first child, the sort function must only read the new data for the first of the two changed children, otherwise the resorting of the children will be wrong.

This generally means that if you don’t fully control the data model, you have to duplicate the data that affects the sorting and filtering functions into the widgets themselves.

Another alternative is to call FlowBox.invalidateSort() on any model change, but that is more expensive.

getChild

public @Nullable Widget getChild()

Gets the child widget of self.

Returns:

the child widget of this FlowBoxChild

getIndex

public int getIndex()

Gets the current index of the this FlowBoxChild in its GtkFlowBox container.

Returns:

the index of the child, or -1 if the this FlowBoxChild is not in a flow box

isSelected

public boolean isSelected()

Returns whether the this FlowBoxChild is currently selected in its GtkFlowBox container.

Returns:

true if this FlowBoxChild is selected

setChild

public void setChild(@Nullable Widget child)

Sets the child widget of self.

Parameters:

child - the child widget

activate

protected void activate()

onActivate

public SignalConnection<FlowBoxChild.ActivateCallback> onActivate(FlowBoxChild.ActivateCallback handler)

Emitted when the user activates a child widget in a GtkFlowBox.

This can happen either by clicking or double-clicking, or via a keybinding.

This is a keybinding signal, but it can be used by applications for their own purposes.

The default bindings are Space and Enter.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• FlowBoxChild.ActivateCallback.run()

emitActivate

public void emitActivate()

Emits the "activate" signal. See onActivate(org.gnome.gtk.FlowBoxChild.ActivateCallback).

builder

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

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

Returns:

the builder object
