Method Details

run

boolean run(TreeModel model,
 TreePath path,
 TreeIter iter)

Type of the callback passed to gtk_tree_model_foreach() to iterate over the rows in a tree model.

upcall

default int upcall(MemorySegment model,
 MemorySegment path,
 MemorySegment iter,
 MemorySegment data)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gtk.TreeModel, org.gnome.gtk.TreePath, org.gnome.gtk.TreeIter) 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
