  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!

  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:

  void setBusy​(KString msg,
               int delay,
               int progress)

  Sets the UI busy state and optionally updates the message and/or progress.

  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:

  msg - Optional message, null for none.

  delay - Delay of lock spinner: -2 for default (1.5 second), -1 disabled, 0=no delay, >0 wait time in milliseconds (1-20000, i.e. 20 seconds).

  progress - Progress value, -1 for none, otherwise a value between 0 and 100.

  Throws:

  java.lang.IllegalArgumentException - If progress value is not -1 or 0 to 100, or delay is smaller than -2 or larger than 20000.

• 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​(java.lang.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:

  runnable - The runnable to be notified, null for none.

  Returns:

  true if the runnable will be called (if present), false if it will not be called.

• getCurrentFocus

  UIComp getCurrentFocus()

• sendStat

  void sendStat​(java.lang.String event,
                DeviceParameter... params)

• saveDeviceParameters

  boolean saveDeviceParameters​(DeviceParameter... params)

  This method will always fail if the device is not running with iiziRun.

  Parameters:

  params - The parameter to retrieve.

  Returns:

  true for success, false if iiziRun is not present and device parameters are not present.
