Gtk.CellArea.get_preferred_height_for_width

### Method

# Gtk CellAreaget_preferred_height_for_width

#### Declaration [src]

    void
    gtk_cell_area_get_preferred_height_for_width (
      GtkCellArea* area,
      GtkCellAreaContext* context,
      GtkWidget* widget,
      int width,
      int* minimum_height,
      int* natural_height
    )

#### Description [src]

Retrieves a cell area’s minimum and natural height if it would be given the specified `width`.

`area` stores some geometrical information in `context` along the way while calling `gtk_cell_area_get_preferred_width()`. It’s important to perform a series of `gtk_cell_area_get_preferred_width()` requests with `context` first and then call `gtk_cell_area_get_preferred_height_for_width()` on each cell area individually to get the height for width of each fully requested row.

If at some point, the width of a single row changes, it should be requested with `gtk_cell_area_get_preferred_width()` again and then the full width of the requested rows checked again with `gtk_cell_area_context_get_preferred_width()`.

#### Parameters

`context` | `GtkCellAreaContext`
| The `GtkCellArea`Context which has already been requested for widths.
| The data is owned by the caller of the function.
`widget` | `GtkWidget`
| The `GtkWidget` where `area` will be rendering.
| The data is owned by the caller of the function.
`width` | `int`
| The width for which to check the height of this area.
`minimum_height` | `int*`
| Location to store the minimum height.
| The argument will be set by the function.
| The argument can be `NULL`.
| The instance takes ownership of the data, and is responsible for freeing it.
`natural_height` | `int*`
| Location to store the natural height.
| The argument will be set by the function.
| The argument can be `NULL`.
| The instance takes ownership of the data, and is responsible for freeing it.
