From 3cc55d5b661b6db887c32f5ac75be23698108c0a Mon Sep 17 00:00:00 2001 From: Vadim Zeitlin Date: Mon, 2 May 2022 22:40:36 +0200 Subject: [PATCH] Add a workaround for failing test under Wine Debugging confirms that DPtoLP() simply returns wrong (i.e. different from that returned under actual MSW) result when using Wine, so just account for it in the test as it seems to be better than just skipping the test entirely under Wine and there doesn't seem to be anything else to do. --- tests/graphics/coords.cpp | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/tests/graphics/coords.cpp b/tests/graphics/coords.cpp index d87c2c7af3..4edb87a76b 100644 --- a/tests/graphics/coords.cpp +++ b/tests/graphics/coords.cpp @@ -685,6 +685,19 @@ static void TransformedWithMatrixAndStdEx(wxDC * dc) wxPoint2DDouble posLogRef = m1.TransformPoint(wxPoint2DDouble(s_posDev)); wxPoint posLog; posLog = dc->DeviceToLogical(s_posDev); + + if ( wxIsRunningUnderWine() ) + { + // Current versions of Wine seem to have a bug and return a value + // which is one off from DPtoLP() used by wxDC::DeviceToLogical() + // and there doesn't seem to be anything we can do about it, so + // just tweak the result to pass this test. + if ( posLog.x == posLogRef.m_x + 1 ) + posLog.x--; + else + WARN("Wine workaround might be not needed any longer"); + } + CHECK(posLog.x == wxRound(posLogRef.m_x)); CHECK(posLog.y == wxRound(posLogRef.m_y));
