Qt application not resizing properly

I am having a problem with resizing my gui's made from Qt.

In full screen basically they don't scale to the available 开发者_开发百科space.

Here is what i did.

1. Created a gui from Qt Designer.

2. When i preview it and try to maximize it, it scales badly. The same thing happens when i use this generated code for my application(it scales badly when maximized)

Question: What am i doing wrong? Thanks.

You need to set a layout for your your main window and then add spacers in the main layout to keep things floating nicely.

Give the whole widget a grid layoutso it knows how to resize.
