    • MULTIPAGE issue #1 of not focusable page

      Hello.

      I found the issue of MULTIPAGE-widget.
      If some page does not contain any focusable element (for example only TEXT or disabled all widgets) there is a coloring issue:

      if to return from this page to other page which contains the focusable element(s) then this focusable widget will not have a "focusable" color.

      A simple example demonstrates this issue.
      If you select page 1, then select page 2 and then select page 1 again you will see that no one button is colored as focused.

      This issue is present even in ver. 5.50.

      Question: What API-function or message informs that a page of MULTIPAGE was selected?

    • Hi Volodymyr,

      thank you for reporting this issue, we will fix that. About your question, when a new page is selected, a WM_NOTIFICATION_VALUE_CHANGED notification will be sent and the selection will be changed via MULTIPAGE_SelectPage().

      Best regards,

      Hi Florian.

      Is there a way to get a message about new selected page from assigned callback-function of MULTIPAGE-widget, not from callback of its parent window?

      Or how can I fix this issue with color of focused object, what is the best way?
      Best regards,
      Volodymyr.

    • Hi Volodymyr,

      yes, this is doable. WM_NOTIFICATION_VALUE_CHANGED is the value of a WM_NOTIFY_PARENT message. That message gets sent to the parent window, as the name indicates. But you can of course send the message to any other window you'd like to.
      This is how you do it:

      Hi Florian.

      Your way is not usable for me because I create multiple nested MULTIPAGEs (several MULTIPAGEs inside each of tab of top MULTIPAGE, see pictures), so I do not use the WINDOW handle of each nested MULTIPAGE, I am working only with and inside MULTIPAGE's callbacks.

      By the way, this above mentioned issue with MULTIPAGE concerns not only to the color.
      If there is a page with no focusable element and if this page is selected, but the keyboard-activity is applied to another tab, which contains focusable objects.
