How to re-use a Widget inside another project - NEWBIE

[Miklux]

Hi all,
this is my first post and I'm a ** very newbie ** in Qt programming and not very newbie in general OOP.
I'm trying to understand how to reuse some widget that I created (in other projects) in new projects.
I try to explain better.
I created a widget (with its ui and many files .cpp and .h).
Now I want to create a mainwindow where put a certain number of these widgets and I hope to see every widget inside my mainwindow in a fixed position.
Every time that I want to add a new widget, the new position will be near to the previously widget created.
I want that every widget can be removed using a button on the same widget.

How can I do this operations?
Can you suggest some way?
Sorry if the question is banal but I really don't full understand Qt methods and classes.

** Thank you ** in advance for every help you will give me! ;)
Mik

You can simply make new and you can use your own widget. Also check this "Promote widget in Qt Designer"
Eg: MyWidget * gh = new MyWidget; //you will have copy of MyWidget and can access all the functiosn signals and slots inside it.

Now I want to create a mainwindow where put a certain number of these widgets and I hope to see every widget inside my mainwindow in a fixed position.Every time that I want to add a new widget, the new position will be near to the previously widget created.

You can use Layouts to set the position of the widgets basing on your requirement.

I want that every widget can be removed using a button on the same widget.

If "MYWidget " derived from the QDialog or something like this, you will have close by default. If not , You can set close button on your MyWidget and add the close functionality to it.
