Gtk.Widget.compute_point

### Method

# Gtk Widgetcompute_point

#### Declaration [src]

    gboolean
    gtk_widget_compute_point (
      GtkWidget* widget,
      GtkWidget* target,
      const graphene_point_t* point,
      graphene_point_t* out_point
    )

#### Description [src]

Translates the given `point` in `widget`‘s coordinates to coordinates relative to `target`’s coordinate system.

In order to perform this operation, both widgets must share a common ancestor.

#### Parameters

`target` | `GtkWidget`
| The `GtkWidget` to transform into.
| The data is owned by the caller of the function.
`point` | `graphene_point_t`
| A point in `widget`‘s coordinate system.
| The data is owned by the caller of the function.
`out_point` | `graphene_point_t`
| Set to the corresponding coordinates in `target`‘s coordinate system.
| The argument will be set by the function.
| The data is owned by the caller of the function.

#### Return value

Returns: | `gboolean`
| `TRUE` if the point could be determined, `FALSE` on failure. In this case, 0 is stored in `out_point`.
