Hello Ebru, It looks like you have your VBox Sizer not setup to take the full size of the window, which will cause this behavior as you are seeing. The easiest way to ensure that all sizers are properly sizing to the size of the screen, is to ensure that whenever you add something to a sizer, you specify the attributes in which to size the child window, as such. Programmatic way: Gtk::HBox#pack\_start(child, expand = true, fill = true, padding = 0) Gtk::VBox#pack\_start(child, expand = true, fill = true, padding = 0) Expand, when true, will ensure that no matter the size of the child widget, the container will expand from border to border, allowing the maximum size available for children widgets. Fill, when true, will ensure that no matter the size of the container, the child will use all available space in the container for itself. Padding will give you x amount of pixel spaces between the border of the container, and the border of the child widget that is being added to the Box. Glade GUI Designer way: When you select a child widget, Click on the Packing Tab, and check true or false for the Expand and Fill options. You may also have to select a different sizer to adjust a parent sizer, that has a child sizer in it. To select a parent sizer of a child sizer, right click on the control, and you should get the option to select the parent sizer from the context menu.
