Creating subproject using menu in Qt

[yy_pc_programmer]

Hello . I am learning qt for the first time. What I want to do is create subproject. But I don't know how to do this in qt. How can I track a step? So I don't want to build from codes. I just want to create from qt's menus. Is it possible?

Thank you very much for your sharing. I previously created a database linked project with a login screen. How can I link this to another project, as a subproject? Actually, I want to do this: When I enter the general project, I want the login page to appear first. Then redirect me to the other subproject after successful login. I hope I could explain. thanks...

Hi
Im not sure you want a sub project as such as that will create the DB app as its own exe.

So to embed it into other app, often you would simply add the needed files (*. and *.cpp)
and then simply create an instance of you DB login form.

Depending on the effect you want.
You can either popup the login dialog from MainWindow
or from main.

Hi
the docs says
"To remove subprojects, right-click the project name in the Projects view, and select Remove Subproject in the context menu."

So is there such menu if you right click the LoginPage.pro ?

[yy_pc_programmer]

Yeah. That option is in the menu. But not selected

[yy_pc_programmer]

well. It doesn't allow me to choose. And I can't choose.

@yy_pc_programmer

ok. im not sure why.

You can manually remove the files then. and fixup the Project.pro to clean any mention of
LoginPage
