CustomLayout

gtk.custom_layout.CustomLayout uses closures for size negotiation.

A GtkCustomLayout uses closures matching to the old gtk.widget.Widget virtual functions for size negotiation, as a convenience API to ease the porting towards the corresponding `GtkLayoutManager virtual functions.

class CustomLayout : LayoutManager {

this(gtk.types.CustomRequestModeFunc requestMode, gtk.types.CustomMeasureFunc measure, gtk.types.CustomAllocateFunc allocate);

}

Constructors

this this(gtk.types.CustomRequestModeFunc requestMode, gtk.types.CustomMeasureFunc measure, gtk.types.CustomAllocateFunc allocate): Creates a new legacy layout manager.

allocate void allocate(gtk.widget.Widget widget, int width, int height, int baseline): Assigns the given width, height, and baseline to a widget, and computes the position and sizes of the children of the widget using the layout management policy of manager.
getLayoutChild gtk.layout_child.LayoutChild getLayoutChild(gtk.widget.Widget child): Retrieves a gtk.layout_child.LayoutChild instance for the gtk.layout_manager.LayoutManager, creating one if necessary.
getRequestMode gtk.types.SizeRequestMode getRequestMode(): Retrieves the request mode of manager.
getWidget gtk.widget.Widget getWidget(): Retrieves the gtk.widget.Widget using the given gtk.layout_manager.LayoutManager.
layoutChanged void layoutChanged(): Queues a resize on the gtk.widget.Widget using manager, if any.
measure void measure(gtk.widget.Widget widget, gtk.types.Orientation orientation, int forSize, int minimum, int natural, int minimumBaseline, int naturalBaseline): Measures the size of the widget using manager, for the given orientation and size.
