Hello, I'd like to ask you if there is a reason why CXTPPropertyGridItem::OnDrawItemValue() and CXTPPropertyGridItem::GetValueRect() use different-height rectangles? The documentation says: virtual BOOL OnDrawItemValue( CDC& dc, CRect rcValue); virtual CRect GetValueRect(); Returns - A CRect object that represents the bounding rectangle of the item value's text. So both rects should be a bounding box of the value part, shouldn't they? However, in my override of CXTPPropertyGridItem class, in OnDrawItemValue() I get a height which is different from what GetValueRect() returns -- this makes my owner-drawn propertygrid items look strange (jumping one pixel up and down sometimes, according to some special actions I use). Can you please explain why the rectangles are different? Or is this simply a bug? Is there a solution for this (using XTP v11.1)? Thank you, in advance! |

Hello,
for OnDrawItemValue doesn't used bottom line.
you can add in your code
CRect rcBound(rcValue);
rcBound.bottom++; ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

| I see. And can I rely on that this line will be always exactly 1 pixel high - with all the different themes and styles a PropertyGrid can have? |
