Method Summary

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

Method Details

run

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

Deprecated.

There is no replacement

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.

Parameters:

model - the GtkTreeModelFilter

iter - a GtkTreeIter pointing to the row whose display values are determined

value - A GValue which is already initialized for with the correct type for the column column.

column - the column whose display value is determined

upcall

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

Deprecated.

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

toCallback

default MemorySegment toCallback(Arena arena)

Deprecated.

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
