class: GtkTreeSortableMeta

[312:14] static extends: object

Generated metadata helpers for TreeSortable interface surfaces.

Methods

signals ()

Returns signal metadata for TreeSortable.
- @r A list.

class: GtkTreeSortableSortcolumnchangedCallback

[242:7] extends: object

Generated low-level callback wrapper for GIR callback sort-column-changed.

Members

callbackObj
userFn
userData
hasUserData

Methods

GtkTreeSortableSortcolumnchangedCallback (callback Fn, UserData = null)

Creates one native callback wrapper. The wrapper owns a trampoline that converts native pointers into generated wrapper objects before invoking Fn.
- @p Fn is the Aussom callback implementation.
- @p UserData is retained and passed through to Fn on each invocation when provided.
trampoline (nativeSelf, nativeUserData)

Internal trampoline. Converts native pointer arguments into generated wrapper instances, then invokes the user's callback.
callback ()

Returns the wrapped NativeCallback.
handle ()

Returns the callback as a NativeHandle.
close ()

Closes the underlying NativeCallback.
isClosed ()

Returns true when the callback has been closed.

class: GtkTreeSortable

[15:7] extends: object

The interface for sortable models used by GtkTreeView GtkTreeSortable is an interface to be implemented by tree models which support sorting. The GtkTreeView uses the methods provided by this interface to sort the model.

Methods

GtkTreeSortable (Handle = null)

Creates a new TreeSortable by wrapping a native handle or another wrapper.
- @p Handle is the native handle or another wrapper whose handle to adopt.
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.
connectSignal (string Name, CallbackObj)

Connects one generated callback wrapper to a named signal.
- @p Name is the signal name.
- @p CallbackObj is the generated callback wrapper to connect.
- @r The connected handler id.
disconnectSignalHandler (int HandlerId)

Disconnects one retained signal handler id.
- @p HandlerId is the signal handler id to disconnect.
- @r None.
setOnSortcolumnchanged (callback Fn, UserData = null)

The ::sort-column-changed signal is emitted when the sort column or sort order of @sortable is changed. The signal is emitted before the contents of @sortable are resorted.
- @p Fn is the Aussom callback.
- @p Fn is called with (GtkTreeSortable Self).
- @p UserData is retained and passed through to the generated callback wrapper when provided.
- @r The connected handler id.
get_sort_column_id ()

Fills in @sort_column_id and @order with the current sort column and the order. It returns %TRUE unless the @sort_column_id is %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or %GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.
- @p sort_column_id is The sort column id to be filled in.
- @p order is The GtkSortType to be filled in.
- @r %TRUE if the sort column is not one of the special sort column ids..
has_default_sort_func ()

Returns %TRUE if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.
- @r %TRUE, if the model has a default sort function.
set_default_sort_func (object destroy)

Sets the default comparison function used when sorting to be @sort_func. If the current sort column id of @sortable is %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function. If @sort_func is %NULL, then there will be no default comparison function. This means that once the model has been sorted, it can’t go back to the default state. In this case, when the current sort column id of @sortable is %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.
- @p sort_func is The comparison function.
- @p user_data is User data to pass to @sort_func.
- @p destroy is Destroy notifier of @user_data.
- @r None.
set_sort_column_id (int sort_column_id, string order)

Sets the current sort column to be @sort_column_id. The @sortable will resort itself to reflect this change, after emitting a GtkTreeSortable::sort-column-changed signal. @sort_column_id may either be a regular column id, or one of the following special values: - %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID: the default sort function will be used, if it is set - %GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID: no sorting will occur
- @p sort_column_id is the sort column id to set.
- @p order is The sort order of the column.
- @r None.
set_sort_func (int sort_column_id, object destroy)

Sets the comparison function used when sorting to be @sort_func. If the current sort column id of @sortable is the same as @sort_column_id, then the model will sort using this function.
- @p sort_column_id is the sort column id to set the function for.
- @p sort_func is The comparison function.
- @p user_data is User data to pass to @sort_func.
- @p destroy is Destroy notifier of @user_data.
- @r None.
sort_column_changed ()

Emits a GtkTreeSortable::sort-column-changed signal on @sortable.
- @r None.
