ConnectVisualization ( |
Connects an object to this DataContainer. May be called repeatedly for the same visualization without side effects name="visualization" the object to connect to this DataContainer name="pollingInterval" the time in milliseconds between updates name="alignment" the clock position to align updates to | |
Data ( ) : QVariant>.Dictionary |
Returns the data for this DataContainer | |
DataContainer ( ) : System | ||
DataContainer ( |
Constructs a default DataContainer that has no name or data associated with it | |
Dispose ( ) : void | ||
RemoveAllData ( ) : void | Removes all data currently associated with this source If you call removeAllData() on a DataContainer, you need to either trigger the scheduleSourcesUpdated() slot for the data engine it belongs to or call checkForUpdate() on the DataContainer. | |
SetData ( string key, Qyoto.QVariant value ) : void | Set a value for a key. This also marks this source as needing to signal an update. If you call setData() directly on a DataContainer, you need to either trigger the scheduleSourcesUpdated() slot for the data engine it belongs to or call checkForUpdate() on the DataContainer. name="key" a string used as the key for the data name="value" a QVariant holding the actual data. If a null or invalid QVariant is passed in and the key currently exists in the data, then the data entry is removed | |

CheckForUpdate ( ) : void | Checks whether any data has changed and, if so, emits dataUpdated(). | |
CreateProxy ( ) : void | ||

SetNeedsUpdate ( ) : void | ||
SetNeedsUpdate ( bool update ) : void | Indicates that the data should be treated as dirty the next time hasUpdates() is called. This is needed for the case where updateRequested() is triggered but we don't want to update the data immediately because it has just been updated. The second request won't be fulfilled in this case, because we never updated the data and so never called checkForUpdate(). So we claim it needs an update anyway. | |
TimeSinceLastUpdate ( ) : uint | Returns how long ago, in msecs, that the data in this container was last updated. This is used by DataEngine to compress updates that happen more quickly than the minimum polling interval by calling setNeedsUpdate() instead of calling updateSourceEvent() immediately. |
