CustomLayout

GtkCustomLayout uses closures for size negotiation.

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

class CustomLayout : LayoutManager {

protected

GtkCustomLayout* gtkCustomLayout;

GtkCustomLayout* getCustomLayoutStruct(bool transferOwnership);

void* getStruct();

this(GtkCustomLayout* gtkCustomLayout, bool ownedRef);

static GType getType();

this(GtkCustomRequestModeFunc requestMode, GtkCustomMeasureFunc measure, GtkCustomAllocateFunc allocate);

}

Constructors

this this(GtkCustomLayout* gtkCustomLayout, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(GtkCustomRequestModeFunc requestMode, GtkCustomMeasureFunc measure, GtkCustomAllocateFunc allocate): Creates a new legacy layout manager.
