将菜单项链接到Qt Creator中的不同小部件

Question

I have created several menu items in the Qt creator, for example : Item X Item Y Item Z
after creating the menu items, I created different classes with different ui for each item - for example Item_x.cpp Item_x.h and Item_X.ui and added my content to each one

now I want to be able to link Item X to Item_x.ui so when the user clicks on the Item X that specific content is loaded . The other issue is that I already have a mainwindow.ui and the menu is set up there.
I am not sure how to connect each Item to its ui, so when the user clicks Item X the Item_x.ui content appears

There are few possible solutions. May be in your situation QStackedWidget is the best one. You can put instance of QStackedWidget in your mainwindow. After it you can append in this QStackedWidget all your three screens (just call addWidget method for each window on the initialization step of your application). After it, each time user click on item on main menu, your application will change current visible screen in QStackedWidget (you have to implement code for it, of course).
