Method Summary

Modifier and Type	Method	Description
boolean	run(TreeModel model, TreeIter iter)	Deprecated. There is no replacement.
default MemorySegment	toCallback(Arena arena)	Deprecated. Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment model, MemorySegment iter, MemorySegment data)	Deprecated. The upcall method is called from native code.

Method Details

run

@Deprecated
boolean run(TreeModel model,
 TreeIter iter)

Deprecated.

There is no replacement.

Function type for determining whether the row pointed to by iter should be rendered as a separator. A common way to implement this is to have a boolean column in the model, whose values the GtkTreeViewRowSeparatorFunc returns.

upcall

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

Deprecated.

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

toCallback

default MemorySegment toCallback(Arena arena)

Deprecated.

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
