QDockWidget Splitter Icon not visible in QMainWindow

[km22]

Hello,
I`ve added a QDockWidget to QMainWindow. In Designer i see the Splitter icon to change size of DockWidget.
When i run the application the Splitter icon is not visible. Any suggestions?
I use Qt 5.1.0 with Qt Creator 2.8.1 on Windows.

Hi,

Do you mean the mouse cursor ?

Hello!
Yes, i mean the mouse cursor!

are you sure you don't mean the handle?
you can set the style of it (so make it show) with the stylesheet http://doc.qt.io/qt-4.8/stylesheet-examples.html#customizing-qsplitter

No. I mean the mouse cursor!
When i run the application can resize the dock window on the corresponding position, but the Qt::SplitHCursor or Qt::SplitVCursor doesn`t appear. Mouse cursor is always Qt::ArrowCursor.
In Qt Creator Design the Qt::SplitHCursor and Qt::SplitVCursor become visible.
Hmm, what can i do wrong here? Lines of code = 0.

Not the best answer but are you locked to that old version of Qt ? The current being 5.7, you should rather test your application with it.

Thank you !
No, i`m not locked to that version. Maybe i should try a newer one.
