QT 5.1 allows Qwebview to automatically resize with window size

Sometimes we do software, we need to put a map in the Qwebview and so on, need to let qwebview with the size of the window to adjust automatically. To implement this feature, you do not need to use the code, the layout can be done. How to do it with the code, I will not, also did not study.

In the first step, open Mainwindow.ui, in design mode, find the right Qmainwindow, right-click, choose layout---> Grid layout.

In the second step, put a "grid layout" on it, then put a Qwebview control on "Grid Layout", then right-click on the Qwebview control, select "ancestor" in an option, and select "Grid Layout".

This will automatically resize. I personally do not understand what layout, specific is so operation, I also blind operation out.
