Disabling an List Widget Item

[charliefjohnson]

The documentation mentions that for the List widget,  a item can be in unselected, selected, disabled selected and disabled unselected state.   And that you can have a different image for each.

But I  don't see anywhere in the APIs for the List widget, a way to set an item to disabled selected or disabled unselected.   Do these states exist yet ??

The disabled state refers to the state of the entire widget (which you can control through gwinSetEnabled() as well as the corresponding gwinEnable() and gwinDisable() wrappers). With the implementation of the default built-in list widget it's not possible to enable/disable individual list items.

If you need such functionality we recommend implement a custom widget. In this particular case you can simply copy the /src/gwin/gwin_list.h and /src/gwin/gwin_list.c files to your project and modify them accordingly.

Please don't hesitate to ask if you have any further questions. We're happy to help.

I would like to change the text of a list item, but not it's position.  Currently I do that by deleted all the items and the re-adding them back which is time consuming.  (For example if the language is changed from English to French.)  What I'd like is a gwinListItemSetText() or gwinListItemPrintf().

There's currently no existing API to do that as you discovered. I added this feature request to our ToDo list.
Of course you can always add that function yourself if you are in a hurry. The existing functions of the list widget show how to access items in the list.

@inmarket just added the new function named gwinListItemSetText() to the library. You can grab the latest master branch of the repository to use this new feature.

Please let us know if there are any problems.
