• getTopmostPanel

  UIPanelBase getTopmostPanel()

  Gets the current top-most panel.

  Returns:

  The panel, null if none has been created.

• getVirtualizedPanels

  UIPanelBase[] getVirtualizedPanels()

  Gets the cached and sorted array of panels that is currently displayed.

  The index 0 is the topmost panel and the higher the index, the more overlapped the panel is. The highest index is the top-level main panel covering the screen.

  Do not modify this array!

  Returns:

  The virtualized panels.

• getMatchingPanels

  UIPanelBase[] getMatchingPanels(VirtualSpace virtualSpace)

  Gets the panels that matches a VirtualSpace for this client session. The VirtualSpace can be virtualized or not, and the client session environment properties are used to determine the panels in question (i.e. depending on their selectors).

  This method is quite CPU intensive and should NOT be done too often. The return value is however cached during the focus handler mappings from VirtualSpace to the UI, so only one such call is done.

  The ordering is not significant and can be a mix of primary and secondary panels, however the matching panel is the virtualized instance if one is present, otherwise it is the non-virtualized instance.

  Note: The result from this method should not be cached because the matching panels may very well change during a client session due to e.g. a change in client capabilities or alike (that affects the result of the selectors used).

  Parameters:

  virtualSpace - The VirtualSpace to look-up the panels for.

  Returns:

  A cloned cached array of the matching panels.

  The array of matching panels, can be a mix of virtualized and non-virtualized panels!

  The virtualized instance of the property, null if not found.

• getClientContextMenuReference

  String getClientContextMenuReference(UIContextMenu contextMenu, boolean fullPropReference)

  Gets the reference to use for a context menu.

  Parameters:

  contextMenu - The context menu.

  fullPropReference - Flag indicating a full property reference string should be returned, false for short (used internally by the server).

  Returns:

  The reference to use, empty string for none (never null).

  Throws:

  IllegalArgumentException - If the context menu is not a stand-alone context menu but a child of a panel component.

• requestUILock

  ILockState requestUILock()

  Requests a UI lock state. The object returned can be used to set a message below the lock spinner. It can also be used to set a progress indicator, also below the spinner. A progress indicator can also be handled using the lock object.

  Note: You MUST call the objects {link @ILockState#release()} method to release the lock state.

  Returns:

  The lock state object.

  Throws:

  IllegalStateException - If the client session is disposed of.

  Throws:

  IllegalArgumentException - If progress value is not -1 or 0 to 100, or delay is smaller than -2 or larger than 20_000.

• setReady

  void setReady()

  Sets the UI to "ready", i.e. clears busy state.

  Note: the state is not set to ready immediately, merely the busy state. The UI is triggered to be synchronized with the VirtualSpace in the Client Worker thread, and a change of panel may be the result.

  This method is intended to be used with advanced UI programming where a message is used in conjunction with a progress.

  If this functionality is not required, it is recommended to let the AppSessionGyro handle the busy state.

• setReady

  boolean setReady(Runnable runnable)

  Sets the UI to "ready", i.e. clears busy state.

  Note: the state is not set to ready immediately, merely the busy state. The UI is triggered to be synchronized with the VirtualSpace in the Client Worker thread, and a change of panel may be the result.

  Specify a runnable instance if you wish to be notified when the panel is unlocked. This runnable will be called at a later stage from the Client Worker thread.

  The runnable will be be called if the busy state is turned on or the client has been locked.

  This method is intended to be used with advanced UI programming where a message is used in conjunction with a progress.

  If this functionality is not required, it is recommended to let the AppSessionGyro handle the busy state.

  Parameters:

  event - The event name.

  params - Parameters to send, null values and sensitive parameters are ignored.

• saveDeviceParameters

  boolean saveDeviceParameters(DeviceParameter... params)

  Saves parameters on the client device for the current app.

  Sensitive parameters are encrypted with a key kept on the server side. The encrypted data is padded and sent to the client and no key is used on the client side. Only the fingerprint of the server key used is included in the encrypted data. This means that the sensitive parameter is virtually undecipherable on the client side.

  Parameters:

  params - Parameters to save. A DeviceParameter value of null means that the device parameter and its value is removed from storage.

Possible states are DeviceParameter.State.SUCCESS, DeviceParameter.State.UNAVAILABLE, DeviceParameter.State.NOT_FOUND or DeviceParameter.State.ENCRYPT_ERROR.

  Returns:

  true for success of at least one device parameter, false for failure (or no parameters to save). In case of functional failure (i.e. not if a device parameter is not found), an error is logged in the server.

• getDeviceParameters

  boolean getDeviceParameters(DeviceParameter... params)

  Retrieves parameters from the client device for the current app. The variables values and state are filled in before the return of this method call. The state indicates success, some error or if the parameter is not found. The state for each DeviceParameter is either DeviceParameter.State.SUCCESS, DeviceParameter.State.NOT_FOUND, DeviceParameter.State.UNAVAILABLE or DeviceParameter.State.DECRYPT_ERROR.

  Parameters:

  params - The parameters to retrieve.

  Returns:

  true for success, false if device parameters are not present. The return code is true if at least one device parameter was successfully retrieved. If false is returned and the DevParams instance is not found in EnvProps for the client, an error is logged in the server.
