Topic: [solved] Markup Horizontal Scroll
Posted: 08 March 2016 at 7:10am

I have problems with the horizontal scroll when using markup.

Specifying a ScrollViewer etc. in my code but it didn't work.

The I turned to the Markup ChartSample in the MarkupPad, and then I see the same problem.

Making the window small to create both horizontal and vertical scroll-bars, size they are set to Auto.

Here the vertical scroll works correctly, but the horizontal does not work.

Easy to see in the sample.

Hello cpede,

I'm glad to inform you that the issue has already been addressed and fixed. The fix will be available in the next beta or final release.

As hot fix you can change file Source/Markup/Controls/XTPMarkupScrollBar.cpp and rebuild library.
in method CXTPMarkupScrollBar::HitTestScrollBar change last two "rcPart.left" to "rcPart.right"

int CXTPMarkupScrollBar::HitTestScrollBar(POINT pt) const
{
....

   rcPart.right = m_spi.rc.left + m_spi.pxThumbBottom;   //<<<< there
   if(PtInRectTransform(rcPart, pt))
   {
     htResult = XTP_HTSCROLLTHUMB;
     break;
   }
 
   rcPart.right = m_spi.rc.left + m_spi.pxDownArrow;    //<<<< there 
   if(PtInRectTransform(rcPart, pt))
   {
     htResult = XTP_HTSCROLLDOWNPAGE;
     break;
   }
  }
 }
 while(FALSE);
 
 return htResult;
}

Regards,
Oleksandr Lebed
