How to get QT's Debug information in msvc Vs2015?

[Puppy Bear]

Hi, I'm using Qt5.9.3 and vs2015 right here,
I have connected qt to vs with setting the compiler and qt5core.pdb, then I tried to change the subwindow to console with vs, I could receive the warning of connect not set correctly.
However there's still not much information while my Qt program breaks while I'm trying to set up a qrubberband(any other errors have the same problem).

This pic is all I have while my program breaks due to qrubberbands.

When my program breaks, this is all I have right now.
What am I missing to set up qt5 to get debug information? Or maybe I should transfer vs project to Qt project?

By the way how am I able to force a qrubberband to stay inside a qlabel?

something like mouseMoveEvent( endpoint restricted inside the range of qlabel?)

@Puppy-Bear I'm now showing camera's frame by opencv's capture in multi-thread and then transfer the qimage to pixmap with showing them on qlabel, There's some kind of delay , is this the correct way of showing a camera's frame?

Hi,

It depends.

Unless you need some special processing done by OpenCV you might want to consider using the QtMultimedia module.
