Constructor Details
-
FlowBoxChild
Create a FlowBoxChild proxy instance for the provided memory address.- Parameters:
address
- the memory address of the native object
-
FlowBoxChild
public FlowBoxChild()Creates a newGtkFlowBoxChild
.This should only be used as a child of a
GtkFlowBox
.

Method Details
-
getType
-
getMemoryLayout
The memory layout of the native struct.- Returns:
- the memory layout
-
asParent
Returns this instance as if it were its parent type. This is mostly synonymous to the Javasuper
keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" withsuper.methodName()
doesn't work, because it invokes the overridden function pointer again. To chain up, callasParent().methodName()
. This will call the native function pointer of this virtual method in the typeclass of the parent type. -
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
Gets the child widget of this FlowBoxChild.- Returns:
- the child widget of this FlowBoxChild
-
getIndex
public int getIndex()Gets the current index of the this FlowBoxChild in itsGtkFlowBox
container.- Returns:
- the index of the this FlowBoxChild, 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 itsGtkFlowBox
container.- Returns:
true
if this FlowBoxChild is selected
-
setChild
Sets the child widget of this FlowBoxChild.- 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 aGtkFlowBox
.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
andEnter
.- Parameters:
handler
- the signal handler- Returns:
- a signal handler ID to keep track of the signal connection
- See Also:
-
emitActivate
public void emitActivate()Emits the "activate" signal. SeeonActivate(org.gnome.gtk.FlowBoxChild.ActivateCallback)
. -
builder
AFlowBoxChild.Builder
object constructs aFlowBoxChild
with the specified properties. Use the variousset...()
methods to set properties, and finish construction withFlowBoxChild.Builder.build()
.
