From 18198aaea2038cd428c6801c829c3d6f4e48c9d6 Mon Sep 17 00:00:00 2001 From: Vadim Zeitlin Date: Sat, 13 Nov 2010 15:03:26 +0000 Subject: [PATCH] Initialize scrollbar positions in wxGTK correctly. The scrollbar positions stored in wxWindow::m_scrollPos were not initially correct in wxGTK because wxScrollHelper::SetScrollbars() didn't update them and only set the values of the underlying GtkAdjustments themselves. This resulted in filtering out of the first scroll event as the code (wrongly) believed that the scrollbar position hadn't changed. Fix this by setting m_scrollPos to the real scrollbar positions. Closes #12468. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@66142 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- src/gtk/scrolwin.cpp | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/gtk/scrolwin.cpp b/src/gtk/scrolwin.cpp index b13658fd23..dcdc24f8af 100644 --- a/src/gtk/scrolwin.cpp +++ b/src/gtk/scrolwin.cpp @@ -30,7 +30,9 @@ void wxScrollHelper::SetScrollbars(int pixelsPerUnitX, int pixelsPerUnitY, int xPos, int yPos, bool noRefresh) { + m_win->m_scrollPos[wxWindow::ScrollDir_Horz] = m_win->m_scrollBar[wxWindow::ScrollDir_Horz]->adjustment->value = xPos; + m_win->m_scrollPos[wxWindow::ScrollDir_Vert] = m_win->m_scrollBar[wxWindow::ScrollDir_Vert]->adjustment->value = yPos; base_type::SetScrollbars( pixelsPerUnitX, pixelsPerUnitY, noUnitsX, noUnitsY, xPos, yPos, noRefresh); -- 2.50.0
