Hi Harish, The value handler mechanism
does not work appropriately for the CDT <= 3.0.1 You will have to use the current
CDT sources from CVS or wait for the upcoming CDT 3.0.2 and 3.1 releases to
take a full advantage of the value handler mechanism. The value handler mechanism
is the only way to monitor the option value change for now. >'isDirty' which is true only when value of that
option gets changed. But that is private variable so I can't access. So is
there any other way by which I can check if that value is changed. You can use the Option.isDirty()
to check the option dirty state if necessary. Regards, Mikhail -----Original Message----- Hi all, Thanks a lot for your timely help. I have tried following two things, but I have few more issues regarding that 1) I tried setting 'applicabilityCalculator' for my
option. Function 'IOptionApplicability.isOptionEnabled()' is called many times. While debugging it seems that it is called twice when I click on that option and twice more when I change its value. So if I have a message box in that code it will get call four times. So how do I check that my message box gets called only once and that too after value gets change. 2) Also I tried using 'valueHandler' and in that
'EVENT_APPLY' that is value of event is 4 when 'OK' button is clicked. Putting a message box over there works but it will get called even if value of that combobox is not changed. To check that value I have noticed that there is a private Boolean variable 'isDirty' which is true only when value of that option gets changed.
But that is private variable so I can't access. So is there any other way
by which I can check if that value is changed. Thanks a lot in advance.

When the user changes the value of that enumerated option (combo box), I
need to display a message box. So can you please guide me how to add listener to combo box of MBS. Thanks in advance.

MBS. You might try to set the 'applicabilityCalculator' attribute on the enumerated option. Each time the user changes an option with that enum option in view the method IOptionApplicability.isOptionEnabled() will
be called, and you can possibly abuse that method to check the selected enum and popup the message box.

In order to do that, you will have to set the "valueHandler"
option attribute to the class name that implements the org.eclipse.cdt.managedbuilder.core.ImanagedOptionValueHandler interface. After that, in order to handle the option change event, you will need
to handle the EVENT_APPLY event (see the ImanagedOptionValueHandler interface definition) Regards, Mikhail _______________________________________________ cdt-dev mailing list cdt-dev@xxxxxxxxxxx https://dev.eclipse.org/mailman/listinfo/cdt-dev |
