Dimmed tab panels

[Wolfgang]

Hello,

if I dim a numeric control, it cannot be clicked on nor can it be selected.

If I dim a menu entry, I can not see its submenus and the menu cannot be selected.

However, if I dim a tab panel, I can select the tab panel, so that it is displayed. Somehow this looks inconsistent to me.

If this is by design, is there a way to have a tab panel disabled, so it can not be shown?

Using CVI2012, thanks!

It does not seem inconsistent to me: a dimmed control or menu entry can actually be seen, even though it is not operable (that's why you cannot see submenus): the same happens with dimmed tab panels. 

In case you want that a tab panel is not shown you can use SetTabPageAttribute (, , , ATTR_VISIBLE, 0);

Hi Roberto,

Thanks for your comment and sorry for being sloppy: I want to see the panel tab, dimmed, but I don't want the user to be able to select it, so the user should not be able to see the tab panel contents (tab being analogous to a menu, the panel to the submenues...)

I'm not aware of a built-in functionality that permits this behaviour. I suppose you could set a callback for the tab controls and handle EVENT_ACTIVE_TAB_CHANGE: I don't know if this event can be swallowed, but you can test it easily; in case it's not you can return to the previous active panel, which is received as eventData1 parameter.

The current behavior is by design. The thinking is that even though a tab page is dimmed, you still might want to know what all is on that tab page.

You can use the callback to make a tab control behave the way you want it, but it does take a bit of programming. Here is an example of how to do it.

Hope this helps.

Thank you all!
