class: NumericSorter

[14:7] extends: object

Sorts items numerically. To obtain the numbers to compare, this sorter evaluates a [class@Gtk.Expression].

Members

• handleObj
• lib
• retainedCallbacks
• signalHandlerNames
• signalSetterHandlers

Methods

• NumericSorter (expression = null)

  Creates a new numeric sorter using the given @expression. Smaller numbers will be sorted first. You can call [method@Gtk.NumericSorter.set_sort_order] to change this.

  • @p expression is The expression to evaluate.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asSorter ()

  Wraps this handle as Sorter.

  • @r A Sorter object.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setExpression (object Value)

  The expression to evaluate on items to get a number to compare with.

  • @p Value is the new property value.
  • @r None.

• setSortorder (string Value)

  Whether the sorter will sort smaller numbers first.

  • @p Value is the new property value.
  • @r None.

• get_expression ()

  Gets the expression that is evaluated to obtain numbers from items.

• get_sort_order ()

  Gets whether this sorter will sort smaller numbers first.

• set_expression (object expression)

  Sets the expression that is evaluated to obtain numbers from items. Unless an expression is set on @self, the sorter will always compare items as invalid. The expression must have a return type that can be compared numerically, such as %G_TYPE_INT or %G_TYPE_DOUBLE.

  • @p expression is a GtkExpression.
  • @r None.

• set_sort_order (string sort_order)

  Sets whether to sort smaller numbers before larger ones.

  • @p sort_order is whether to sort smaller numbers first.
  • @r None.
