Method Details

run

@Deprecated
boolean run(TreeView treeView,
 TreeViewColumn column,
 TreeViewColumn prevColumn,
 TreeViewColumn nextColumn)

Deprecated.

There is no replacement.

Function type for determining whether column can be dropped in a particular spot (as determined by prevColumn and nextColumn). In left to right locales, prevColumn is on the left of the potential drop spot, and nextColumn is on the right. In right to left mode, this is reversed. This function should return true if the spot is a valid drop spot. Please note that returning true does not actually indicate that the column drop was made, but is meant only to indicate a possible drop spot to the user.

upcall

default int upcall(MemorySegment treeView,
 MemorySegment column,
 MemorySegment prevColumn,
 MemorySegment nextColumn,
 MemorySegment data)

Deprecated.

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