[EEF] making some properties read-only basing on runtime information [message #732255]

Hi,

I'm using EEF to create some data-entry wizards (& property pages).

The elements of my model can be in two status: EDITING or RUNNING. Each element has a derived attribute that returns its own status. Depending on the status of an element, I want its properties to be editable or read-only.

How can I instruct EEF to behave in this way?

this is not possible using the eef component model. but you can do it
programmatically, because EEF provides a readonly status for all its
views. just modify the correct component class to achieve it.

Hi,

jeah, I saw that with EEF I can make some properties read-only, but I need to do that at run-time.

I too was thinking about modifying the generated source code, but I was afraid of keeping this modification consistent during subsequent code generations...

Thanks,
Matteo

you can safely edit the generated code if you write the code between the
"Start of user code / end of user code" lines of every generated class.
next generation will keep your manual code .

Hi Matteo, I'm starting to use EEF and I'm interested in use the generated widgets to populate my own wizards. Do you mind exchanging some basic points that you find particularly useful if you did something similar?

Thanks in advance,
Mauricio
