gtkWidgetSizeRequest {RGtk2} | R Documentation

## gtkWidgetSizeRequest

### Description

This function is typically used when implementing a `GtkContainer` subclass. Obtains the preferred size of a widget. The container uses this information to arrange its child widgets and decide what size allocations to give them with `gtkWidgetSizeAllocate`.

### Usage

    gtkWidgetSizeRequest(object)

### Arguments

``object`` | a `GtkWidget`

### Details

You can also call this function from an application, with some caveats. Most notably, getting a size request requires the widget to be associated with a screen, because font information may be needed. Multihead-aware applications should keep this in mind.

Also remember that the size request is not necessarily the size a widget will actually be allocated.

See also `gtkWidgetGetChildRequisition`.

### Value

A list containing the following elements:

``requisition`` | a `GtkRequisition` to be filled in. [ out ]
