Method Summary

Modifier and Type	Method	Description
void	run(TreePath path, TreeIter iter, @Nullable MemorySegment newOrder)	This signal is emitted when the children of a node in the GtkTreeModel have been reordered.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment sourceTreeModel, MemorySegment path, MemorySegment iter, MemorySegment newOrder)	The upcall method is called from native code.

Method Details

run

void run(TreePath path,
 TreeIter iter,
 @Nullable
 @Nullable MemorySegment newOrder)

This signal is emitted when the children of a node in the GtkTreeModel have been reordered.

Note that this signal is not emitted when rows are reordered by DND, since this is implemented by removing and then reinserting the row.

upcall

default void upcall(MemorySegment sourceTreeModel,
 MemorySegment path,
 MemorySegment iter,
 MemorySegment newOrder)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gtk.TreePath, org.gnome.gtk.TreeIter, java.lang.foreign.MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
