How to set the ***initial*** focus to an option? [message #6561]

I have a ParentCtrl and on it, at the top position, an Option. Below that is a Label and an EditField.

When the application starts, the EditField has the focus.

I would like the Option to have the focus, but I don't know how. "SetFocus()" doesn't work in the constructor.

Surprisingly, "SetFocus()" works well, when I move the focus later on ("OnKey()").

How can I set the focus to the (topmost) option, when the application starts?

Only widgets visible on the screen can have focus (therefore setting it in the constructor cannot work).

However, each TopWindow remembers the "focused child" and when it gets activated, places (restores) actual focus to it. Note that the main purpose of this is to maintain the expexted user experience.

You can change this "focused child" by calling TopWindow's ActiveFocus with child as parameter. If TopWindows is active ("foreground"), child gets focus immediately, otherwise it gets in once TopWindow gets active.

Short answer: Use ActiveFocus Wink

My "work paradigm" forces me, at first to dig instead of to ask. Confused

I shouldn't ... Rolling Eyes

Thank you.

Hello Werner,
if you use the Layout Editor just change the order of the Ctrls - the topmost Control with the value want's focus gets it at first and the next in the list is selected when pressing tab

Thanks.

I'm working on quite a complicated UPT where using the layout editor is not appropriate. But Mirek's answer "Use ActiveFocus" already solved the problem (refer to message #6562).
