So I'm 100% new to ruby qt, I'm used to python, and I got the basics but because the QMenuBar wont align properly with just Qt::Widget I have been trying to figure out the QMainWindow command. I know its like 1000% easy the second you tell me but the .setCentralWidget command doesnt seem to work for ruby so I'm just lost...

Here is my "testing" code if you get the question you really dont need this but if I dont put it up some one wil be like wherreee yourrr codddee!!! I dont get it?

    require 'Qt'

    class Window < Qt::Widget

        slots 'slotAbout()', 'slotExit()', 'slotNew()'


        def initialize(parent = nil)
            super(parent)

    #menubar part 

            @menubar = Qt::MenuBar.new(self)

            @menuHelp = Qt::Menu.new(@menubar)
            @menuHelp.setObjectName('menuHelp')

            @actionNew = Qt::Action.new(self)

因此，与 setCentralWidget 有点混淆的是，您需要将 Qt::Widget 传递给它，而将 Qt::Layout 传递给它会给您一个 NoMethodError。我认为这似乎有点违反直觉，因为大多数人都想为他们的第一个基本 GUI 设置网格、hbox 或 vbox 布局。

将小部件设置为中央小部件后，您可以调用

yourCentralWidget.layout = yourNewLayout

并将您想要的任何布局设置为主窗口。我希望这会有所帮助！
