Widget.getPreferredHeightForWidth

void getPreferredHeightForWidth(int width, out int minimumHeight, out int naturalHeight)

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

The returned request will be modified by the GtkWidgetClass::adjust_size_request virtual method and by any #GtkSizeGroups that have been applied. That is, the returned request is the one that should be used for layout, not necessarily the one returned by the widget itself.

Parameters

widththe width which is available for allocation
minimumHeightlocation for storing the minimum height, or null
naturalHeightlocation for storing the natural height, or null
