TRadioButton problem?

[KEagles]

Hi,
I just finished the 0.9 version of a little opensource program that I made. The only thing getting it from 1.0 is that I can't create grouped radio buttons, you know? If I remember well, in Delphi I just need to set the GroupIndex to an unique number thru the group, and all goes well.
But I can't find this property in Lazarus.
It isn't implemented? Or what?
All my radio buttons works like one big group.

Thanks in advance,
Vítor Baptista.

I wonder how it is suppoesed to work in delphi. In my delphi (D6) there is no such thing as GroupIndex.
IIRC radiobuttons are grouped by a groupbox.

It works quite simple - everything having the same GroupIndex is in the same group.


But actually I didn't find it in BDS 4 / Delphi 2006 either. Maybe it was a Visual Basic property I remember from before Delphi was available even? Must've been nearly a dozen years then

This is how it works here in Delphi 7.
Btw in Lazarus I am supposed to create GroupBoxes for each group?

Also, is there any way that I could create a GroupBox that has no border?
I want it to be completely invisible.

@KEagles: I don't see it in Delphi 10:

No idea if this really needs a groupbox, have you tried a TPanel without borders?

[KEagles]

Yes, TPanels work too.
I just made it.

There's one last thing that I need:
The RadioButtons can't be required.

Like, I MUST have one radiobutton checked, by default.
I need that I can have no radiobutton checked at all.

Does someone knows how to do that?

afaik, having one selected is the standard behaviour of a radio group. What you can do is add one for selecting "none of the above"
