MATLAB: How to set the event priority on GUI

gui

Hi everyone. Here is an basic but important question. Think about a GUI which have a textbox named as edit1 and let us add an event to this textbox by KeyPressFcn. When we press return key, KeyPressFcn will arise and gets the text of edit1. However on the same time edit1_Callback event will arise. By default KeyPressFcn event comes first. How can I change it?

By the way I solved my problem by removing KeyPressFcn event and moving both code under the event of edit1_Callback. Nevertheless, there should be property which users can manage the event priorities.

There is no property to allow the relative priorities of the callbacks to be changed.

MATLAB: SimEvents: Which entity type should event actions be assigned to? Invoker type or target type

Hi Kar,

The testEntry method is invoked before an entity enters a storage. This method allows to either accept or refuse an entity from entering that particular storage. In the case of the storage for Task entities, the callback method name would be TaskTestEntry and for the Failure storage it would be FailureTestEntry.

For this example, when a Failure entity arrives into storage 2, an internal flag can be set in the block that would block Task entities from entering the block. When we are done processing the Failure entity, we can reset the flag so that we can start accepting entities into Storage 1. To check if any entities are waiting to enter storage 1, we can schedule a testEntry event for storage 1.

    for k = first+1:length(data)
        if isnan(data(k))
            numberNaN = numberNaN+1;
        else break
