QML and Qt Quick
-
Hi,
I'm just creating new QtQuick project, compiling / deploying.
If i run that empty application with DrMemory i have this output :Dr. Memory version 1.11.0 build 2 built on Aug 29 2016 02:42:07 Dr. Memory results for pid 6400: "untitled.exe" Application cmdline: ""C:\Users\user\Desktop\DEPEND - DBG_INFO\untitled.exe"" Recorded 115 suppression(s) from default C:\Users\user\Desktop\DrMemory-Windows-1.11.0-2\bin\suppress-default.txt Error #1: UNINITIALIZED READ: reading 0x0028db84-0x0028db88 4 byte(s) within 0x0028db80-0x0028db88 # 0 system call NtUserTrackMouseEvent parameter value #0 # 1 qwindows.dll!?
