control- like this:

that doesn't happened in windows.

how can i get rid from this visual focus?

Try one of these:

• Explicitly set the QApplication style to one that doesn't draw a focus rectangle on the tabs, for example plastique. This might break any custom style sheets. The native look and feel will be gone, too.
• Set the QTabWidget or QTabBar focusPolicy property to NoFocus. The user won't be able to change between tabs using the keyboard.
• Set the QTabWidget documentMode property to true.
