Methods

AddDependency(string, string)

Adds a layout dependency between two zones

public void AddDependency(string dependentZone, string dependsOnZone)

Parameters

dependentZone string

Zone that depends on another's layout

dependsOnZone string

Zone that the dependent zone relies on

ClearZone(string)

Clears a specific zone's content area

public void ClearZone(string zoneId)

Parameters

zoneId string

The zone to clear

GetZoneBounds(string)

Gets the current boundaries of a zone

public Region? GetZoneBounds(string zoneId)

Parameters

zoneId string

The zone identifier

Returns

Region

The zone's current bounds, or null if not found

GetZoneIds()

Gets all registered zone identifiers

public IEnumerable<string> GetZoneIds()

Returns

IEnumerable<string>

Collection of zone IDs

InvalidateAll()

Marks all zones as needing redraw

public void InvalidateAll()

InvalidateZone(string)

Marks a specific zone as needing redraw

public void InvalidateZone(string zoneId)

Parameters

zoneId string

The zone to invalidate

IsZoneDirty(string)

Checks if a zone exists and is dirty

public bool IsZoneDirty(string zoneId)

Parameters

zoneId string

The zone to check
