[cdt-dev] RE:Adding listener to MBS enumerated option

["Harish Dewan" <harishd@xxxxxxxxxxxxxxx>]

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.

Hi all,

I have an enumerated option which has enumeratedOptionValues added. 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.

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.

Hi Harish,

 

You can specify the option value handler in your option definition to
monitor and handle the option value change.

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
