Method Summary

Modifier and Type	Method	Description
void	run(TreeModel model, TreeIter iter, Value value, int column)	A function which calculates display values from raw values in the model.
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, int, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment model, MemorySegment iter, MemorySegment value, int column, MemorySegment data)	The upcall method is called from native code.

Method Details

run

void run(TreeModel model,
 TreeIter iter,
 Value value,
 int column)

A function which calculates display values from raw values in the model. It must fill value with the display value for the column column in the row indicated by iter.

Since this function is called for each data access, it’s not a particularly efficient operation.

upcall

default void upcall(MemorySegment model,
 MemorySegment iter,
 MemorySegment value,
 int column,
 MemorySegment data)

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