CSliderCtrl::SetBuddy; what does it do?
in [MFC]
|
From: Mkennedy1102 on 3 Mar 2005 17:47 I assumed that it functions in much the same way as the buddy window for a CSpinButtonCtrl, but I don't see it actua;;y doing anything when I slide the bar. I was testing the functionality of the CSliderCtrl to try and figuer out why I can;'t get them to work properly, so I whipped up a quick dialog based project with three sliders and three edits. I linked the sliders to the edits, set the ranges on the sliders and executed the program. Sliding the thumb on a slider causes absolutely nothing to happen in the "buddy" window. Is this normal? Do I need to implement the display of the sliders positionmyself? Why bother setting it as a buddy window then, you can use any old window. Or, is there a problem in my commctl32.dll(or similar) that is making my sliders not work as they are supposed to? The issue I'm ahving seems to be that my slider controls are not sending notifications to their parent window. I noticed this in another app I am working on, and which I posted about here : http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.vc.mfc&tid=81a5b2bd-d741-4daf-bd06-38db77a9efcb&p=1 So, back to my question.....am I diagnosing this correctly? Is the lack of response in the "buddy" window another indicator that my controls are not sending the notifications tha they should be sending? Is there a heaeer, library or something else that I should be including to getthis to work? If it helps, I'm running XP Pro SP2 and VS 6.0 Professional (Visual C++ 6.0). Any kind of ideas greatly appreciated.

I think all it does is position the buddy windows centered at the left/top or right/bottom of the slider/trackbar saving you the steps necessary to calculate these coords yourself. It should also automatically reposition them on resize/reposition of the slider/trackbar as well as cache the HWNDs so you can retrieve them via CSliderCtrl::GetBuddy/TBM_GETBUDDY. -- Jeff Partch [VC++ MVP]
From: Joseph M. Newcomer on 4 Mar 2005 03:36 Showing some code might help. You also need to set the "Set Buddy Integer" style. Mostly, the correct way to handle this is to put the edit control at tab position N and the spin control at tab position N+1 and use the Auto-Buddy style. joe On Thu, 3 Mar 2005 14:47:02 -0800, Mkennedy1102 <Mkennedy1102(a)discussions.microsoft.com> wrote: >I assumed that it functions in much the same way as the buddy window for a >CSpinButtonCtrl, but I don't see it actua;;y doing anything when I slide the >bar.
