GUI enhancement

Hello Everyone,

I have a few questions about User Interface in Qt

I'm using Qt creator to do my work, I have a QMainWindow application , which contains central widget, also it contains dock widgets

I have 2 issues at this point

1- There is not distinction in the boundaries between the central widget, and the dock widgets, also no distention between the dock widgets themselves, so how to solve this issue?

2- the dockabe widgets always start very wide, and I have to resize it manually every time, even though I have put the size policy to minimum to every dock widget

I've attached a picture with what I already have

thanks very much
