Adopt hierarchical structure as shown in Figure 1, function view only needs to know that it has several coordinate system, as coordinate system 1 and coordinate system 2, do not need to know that coordinate system 1 and coordinate system 2 have how many traces, a how many cursor, same coordinate system 1 only needs to know its two traces and two cursors, is respectively trace 1, trace 2, cursor 1, cursor 2, and does not need to know that trace 2 has how many frequency markings.
View elements classified and is organized into hierarchical structure, being conducive to the expansion of function view.Usually when the demand of function view changes, all need increase or delete one or more view elements, adopt the view elements of hierarchical structure, in increase or when deleting one or more view elements, only need amendment to have the definition of the top level view element contacted directly with it.
Be described below in conjunction with the bookkeeping of concrete example to view elements hierarchical structure of the present invention.
Example 1
Certain instrument escalates into binary channels power measurement simultaneously by original single channel power measurement, at this moment need for coordinate system increases a trace for display channel 2 power measurements, for the coordinate system 2 in Fig. 1, only need the definition adding trace 2 in the definition of coordinate system 2 in the present invention, and the definition of view, cursor, frequency marking is all without the need to change.
Example 2
Be limited to the screen size of certain instrument, user requires only to retain a frequency marking, deletes other all frequency marking, for the trace 2 in Fig. 1, only need the definition of deleting frequency marking 2 and frequency marking 3 in the definition of trace 2 in the present invention, and the definition of view, coordinate system, cursor is all without the need to change.
Usual a kind of measurement function view can comprise multiple coordinate system, and each coordinate system comprises again multiple cursor and many traces, and every bar trace comprises again multiple frequency marking.For the complicated surveying instrument of function, often kind of measurement function view can comprise up to a hundred view elements, the view elements that complete machine software comprises can reach thousands of, often kind of measurement function view additionally provides coordinate system coupling, frequency marking coupling and cursor coupling function simultaneously, and this makes also must set up contact between view elements.For managing multi views element and the contact of setting up between them, view elements management system imported view element manager of the present invention, view elements class for different levels designs exclusive view elements manager for managing the relation between each view elements of this level, to realize the coupling function between view elements.
As shown in Figure 2, the view elements manager of view elements management system of the present invention comprises coordinate system manager, trace manager, cursor manager and frequency marking manager.
A view comprises a coordinate system manager and multiple coordinate system, quoting of all coordinate systems is all passed to coordinate system manager when initialization by view, this rear view no longer has direct correlation with coordinate system, view is all realized by coordinate system manager all operations of coordinate system, and coordinate system manager is responsible for relation, state and display translation between each coordinate system of management specially.
A coordinate system comprises a trace manager and many traces, quoting of all traces is all passed to trace manager when initialization by coordinate system, after this coordinate system also no longer trackdown line have direct correlation, coordinate system is all realized by trace manager all operations of trace, and trace manager is responsible for relation, state and display translation between each bar trace of management specially.
By that analogy, a coordinate system comprises a cursor manager and multiple cursor, quoting of all cursors is all passed to cursor manager when initialization by coordinate system, after this coordinate system also no longer has direct correlation with cursor, coordinate system is all realized by cursor manager all operations of cursor, and cursor manager is responsible for relation, state and display translation between each cursor of management specially.
Article one, trace comprises a frequency marking manager and multiple frequency marking, quoting of all frequency markings is all passed to frequency marking manager when initialization by trace, after this trace also no longer has direct correlation with frequency marking, trace is all realized by frequency marking manager all operations of frequency marking, and frequency marking manager is responsible for relation, state and display translation between each frequency marking of management specially.
Imported view element manager is in charge of coordinate system, trace, cursor, the attribute of frequency marking and operation, greatly can simplify the incidence relation between view elements, make the function responsibility of each view elements definitely, and be conducive to the expansion of function view.
When the demand of function view changes, usually need to change the incidence relation between view elements, traditional way needs to find out all relation tables associated with view elements, and revises one by one, and efficiency is very low; After imported view element manager, a view elements manager that needs associate with view elements with amendment, workload is few, and efficiency is high.
Coordinate system manager of the present invention, trace manager, cursor manager are identical with the structure of frequency marking manager, include query interface, output interface, relation table three parts, query interface inquires about the state of each view elements of this level, and the packing of the state of view elements is sent to output interface; Output interface receives view elements status data, and refreshes relevant view elementary state; All view elements indexes that relation table inquiry associates with input view elements.

The workflow of coordinate system manager is as follows: according to the index of input coordinate system, the output coordinate lashing that all associateds found out by query relation table draws, then the state of query interface inquiry input coordinate system is called, and output interface is issued in packing, output interface is after receiving coordinate status data, draw the state refreshing relative coordinate system respectively according to output coordinate lashing, realize the coupling function of coordinate system.
Below for the coordinate system coupling function in practical application, introduce the realization flow of coordinate system manager.
The transverse axis initial value of a coordinate system, transverse axis stop value, longitudinal axis initial value, longitudinal axis stop value are normally set in all coordinate systems associated with it by coordinate system coupling function, that is make related coordinate system have identical transverse axis initial value, transverse axis stop value, longitudinal axis initial value, longitudinal axis stop value.When user have changed the state of coordinate system 1, namely have modified the transverse axis initial value of coordinate system 1, transverse axis stop value, longitudinal axis initial value, during in longitudinal axis stop value one value, coordinate system manager can according to the index of coordinate system 1, and the index of the coordinate system 2 and coordinate system 3 associate with coordinate system 1 found out by query relation table, then calls query interface and inquires about the transverse axis initial value obtaining coordinate system 1, transverse axis stop value, longitudinal axis initial value, longitudinal axis stop value, and these data are packed, send to output interface, the coordinate system 2 that output interface obtains according to previous queries and the index of coordinate system 3 and the state data packets of coordinate system 1, call its Flushing status interface, respectively by the transverse axis initial value of coordinate system 2 and coordinate system 3, transverse axis stop value, longitudinal axis initial value, longitudinal axis stop value is arranged to the transverse axis initial value of coordinate system 1, transverse axis stop value, longitudinal axis initial value, longitudinal axis stop value, at this moment coordinate system 1, the state of coordinate system 2 and coordinate system 3 is consistent, and also namely achieves the coupling function of coordinate system.
As can be seen from the schematic diagram of coordinate system manager, the coordinate system in figure can be the coordinate system of linear coordinate system, logarithmic coordinate system, chromatogram coordinate system or other type; The state of coordinate system can be not only transverse axis initial value, transverse axis stop value, longitudinal axis initial value, the longitudinal axis stop value of coordinate system, also can be other states such as the transverse axis ruling number of coordinate system, longitudinal axis ruling number, ruling color; Query interface, output interface all do not associate with operating system platform with the realization of relation table, and that is view elements manager of the present invention is a view elements logic manager, can cross-platform.
Technical solution of the present invention does not associate with any operating system platform, but externally provide expansion interface for the realization of view elements management system, as shown in Figure 4, only need realize with local interface the management that corresponding expansion interface can realize view elements for different operating system platforms.
View elements is organized into hierarchical structure by the present invention, when functional requirement changes, without the need to redefining whole view structure, only needing the definition of the view elements that amendment is relevant to function, being conducive to the expansion of function.
Further, when increasing or delete a view elements, the present invention only needs to revise the definition having the top level view element contacted directly with it, and workload is little and efficiency is high.
Further, the concept of imported view element manager of the present invention, reduces the coupling between view elements, when realizing the coupling function of view elements, is responsible for realization, functional independence by the view elements manager of each level, and is conducive to expansion.
Technical scheme of the present invention does not associate with any operating system platform, can share this technology between each platform.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
