ErrorPopup The ErrorPopup viewer is a singleton class in ATK. This viewer is a dialog window which pops up as soon as it receives an error. The error description is displayed and the user can get the detailed description of the error. The ErrorPopup window waits for the user click to disappear. Normally the ErrorPopup should NOT be used for the errors which occur during the attribute refreshing. It should be used for errors which occur rarely like the setting of an attribute or the execution of a command. The code sample below shows how to use ErrorPopup : ErrorPopup errpp = ErrorPopup.getInstance(); AttributeList attl = new AttributeList(); CommandList cmdl = new CommandList(); attl.addSetErrorListener(errpp); cmdl.addErrorListener(errpp); Note that the ErrorPopup is only added as “SetErrorListener” to the attribute list.
Synoptic drawing and programming ATK provides a complete synoptic system. As already mentioned in the introduction, the main idea of the synoptic drawing and viewing system is to provide the application designer with a simple and a flexible way to draw a synoptic and to animate it at runtime according to the values and states read from the control system. What is a synoptic application? In an application based on a synoptic the user can see a “free style” drawing, in which different parts can report on the tango device states and/or the tango attribute values of the control system. We say that the drawing is “animated” at run-time according to the values / states of the control system objects. The following picture is the snapshot of the ESRF Linac control application based on a synoptic. The synoptic is the drawing in the center with the background color in blue. As you can see the drawing components in the synoptic have different colors according to the device state attribute to which they are linked. For example the drawing component linked to “elin/gun/aux/State” is colored in orange because the value of this state attribute is Alarm. Moreover you can see the red arrow (Beam Stop) on the slider pointing to the value of the tango attribute “elin/master/op/SRCT_limit” which is 92 as it is also represented outside of the synoptic on the top of the window. What kind of animations are provided at run-time? The run-time behavior of the synoptic is predefined in ATK and it depends on the type of the graphic object (free drawing, dynos, sliders, buttons, …) on one hand and the tango control
