Method Details

run

void run(SorterChange change)

Emitted whenever the sorter changed.

Users of the sorter should then update the sort order again via gtk_sorter_compare().

SortListModel handles this signal automatically.

Depending on the change parameter, it may be possible to update the sort order without a full resorting. Refer to the Gtk.SorterChange documentation for details.

upcall

default void upcall(MemorySegment sourceSorter,
 int change)

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
