RE: [GD-Windows] Troubles with Win32 slider

[Jon W. <hp...@mi...>]

The slider will send you WM_SCROLL messages. Actually, working=20
with sliders in Win32, I've found to be a pain in the butt,=20
because they're so different from many other controls.

Here's code from a wrapper I wrote for personal use a long time=20
ago:

  virtual int value()
    {
      return SendMessage( controlWindow_->window()->hWnd(), TBM_GETPOS, =
0, 0 );
    }
  virtual void setValue( int v )
    {
      LRESULT lr =3D SendMessage( controlWindow_->window()->hWnd(), =
TBM_SETPOS, TRUE, v );
    }

Cheers,

                / h+

Subject: [GD-Windows] Troubles with Win32 slider


I put a vanilla Win32 slider in a dialog (in VC6's resource editor), and =
I can't seem to get it work.

This is probably very easy once you know how to do it, but neither the =
MSDN nor Google seems to answer this basic question clearly : how do I =
get back the slider's position ? (!)

Note that :
- For checkboxes or radio buttons it worked like a charm using, for =
example, IsDlgButtonChecked(). I'm looking for similar brain-dead =
functions to handle sliders.
- I don't want to / can't use MFC here.
- I tried to catch various messages in the parent window, =
GetScrollPos(), etc, nothing seems to work.

I'll appreciate a small overview, or a working link to a decent =
tutorial.

Thanks,

- Pierre
