The task amount that actually accomplishes color setting is carried out to all subassembly units and components of the assembly unit, be to be assembled from top layer
Unit A0 starts setting, specifically comprises the following steps:
5.1) it initializes, sets the index i=0 of the subobject set of assembly unit A；It enters step 5.2)；
5.2) judge to index the subobject set length whether i is less than assembly unit A, if so, entering step 5.3)；Such as
Fruit is no, terminates；
5.3) whether i-th of subobject A.children [i] for judging assembly unit A is assembly unit, if it is assembly
5.4) unit enters step, if not, but components, then enter step 5.5)；
5.4) this algorithm of recursive call completes the color setting of subassembly unit A.children [i], subsequently into step
5.6)；
5.5) assembly unit task completed percentage, sets the color of components, and green indicates to be completed, blue indicate just into
Row, grey expression do not start, and red indicates to have exceeded the time limit；Subsequently into step 5.6)；
5.6) i self-propagation is indexed, 5.2) i++ is entered step.
6) periodic refreshing progress display.
By setting time interval, newest Assembling Production procedural information is periodically reacquired, recalculates and appoints by assembly unit
Business performance, and set components color and render displaying again.
It should be noted that referring to Fig. 2, the structure of an example after assembly unit partition and fittage association definition
By assembly unit A0, assembly unit A1, assembly unit A2, assembly unit A3, assembly unit A1.1, assembly unit A1.2, assembly

It carries out, grey expression does not start, and red indicates to have exceeded the time limit；The color of assembly unit and its components is using Deep Recursion Algorithm
It carries out calculating setting, is to start to calculate with top layer assembly unit；
Step 6: periodic refreshing progress display；By setting time interval, newest Assembling Production procedural information is periodically reacquired,
Task performance is recalculated by assembly unit, and sets components color and renders displaying again.
