class: StringSorter

[16:7] extends: object

Sorts items by comparing strings. To obtain the strings to compare, this sorter evaluates a [class@Gtk.Expression]. It does the comparison in a linguistically correct way using the current locale by normalizing Unicode strings and possibly case-folding them before performing the comparison.

Methods

• StringSorter (expression = null)

  Creates a new string sorter that compares items using the given

  • @expression. Unless an expression is set on it, this sorter will always compare items as invalid.
  • @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.

• setCollation (string Value)

  The collation method to use for sorting. The GTK_COLLATION_NONE value is useful when the expression already returns collation keys, or strings that need to be compared byte-by-byte. The default value, GTK_COLLATION_UNICODE, compares strings according to the Unicode collation algorithm.

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

• setExpression (object Value)

  The expression to evaluate on item to get a string to compare with.

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

• setIgnorecase (bool Value)

  If sorting is case sensitive.

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

• get_collation ()

  Gets which collation method the sorter uses.

• get_expression ()

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

• get_ignore_case ()

  Gets whether the sorter ignores case differences.

• set_collation (string collation)

  Sets the collation method to use for sorting.

  • @p collation is the collation method.
  • @r None.

• set_expression (object expression)

  Sets the expression that is evaluated to obtain strings from items. The expression must have the type %G_TYPE_STRING.

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

• set_ignore_case (bool ignore_case)

  Sets whether the sorter will ignore case differences.

  • @p ignore_case is %TRUE to ignore case differences.
  • @r None.
