CSliderCtrl Click

Posted on 2011-03-02

I use a CSliderCtrl and the HScroll for the position change. This works well for move the thumb, but it do not work if I click into the line. Normaly if I click into the line, the tumb will go to this position. How I have to expand the HScroll that it will be work.
Attached the function I use currently.

void CAudioGrabSource::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
	if (pScrollBar->GetSafeHwnd() == mAGrabPlayPos.GetSafeHwnd())
		switch (nSBCode)
				m_bScrolling = true;

				m_bScrolling = false;


	__super::OnHScroll(nSBCode, nPos, pScrollBar);

Hi Ocrana,

>> Normaly if I click into the line, the tumb will go to this position.
I don't think this is the default behavior - at least I cannot reproduce this with a normal slider control added to a dialog. When clicking on the line depending on the position relative to the slider's handle a 'SB_PAGEUP' or 'SB_PAGEDOWN' scroll message is sent, then the handle moves a given amount (which you can set with CSliderCtrl::SetPageSize) toward the position where the line was clicked.
