gtkWidgetGetChildRequisition {RGtk2} | R Documentation

## gtkWidgetGetChildRequisition

### Description

This function is only for use in widget implementations. Obtains `widget->requisition`, unless someone has forced a particular geometry on the widget (e.g. with `gtkWidgetSetSizeRequest`), in which case it returns that geometry instead of the widget's requisition.

### Usage

    gtkWidgetGetChildRequisition(object)

### Arguments

``object`` | a `GtkWidget`

### Details

This function differs from `gtkWidgetSizeRequest` in that it retrieves the last size request value from `widget->requisition`, while `gtkWidgetSizeRequest` actually calls the "size_request" method on `widget` to compute the size request and fill in `widget->requisition`, and only then returns `widget->requisition`.

Because this function does not call the "size_request" method, it can only be used when you know that `widget->requisition` is up-to-date, that is, `gtkWidgetSizeRequest` has been called since the last time a resize was queued. In general, only container implementations have this information; applications should use `gtkWidgetSizeRequest`.

### Value

A list containing the following elements:

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