Working with Multiple Forms in Qt C++ - Qt Widgets Crash Course

In this tutorial, you'll learn how to work with multiple forms in Qt C++, and how to exchange information between them. We'll use the constructor of the second form to pass data into it, and then we'll get data from it using signals and slots. We'll also explore the powerful connect function, which allows us to create event handlers at runtime.
With step-by-step instructions and clear explanations, you'll learn how to use these techniques to build more complex applications with Qt. Whether you're a beginner or an experienced developer, this tutorial will give you the tools you need to take your projects to the next level.

in mainwindows.cpp file, you create a pointer to Dialog every time button clicked. but you didn't delete it. you will end up with memory problem

[@wearesciber]

Well actually, since i passed "this" to the constructor when creating the object, it sets up a parent child relationship between the mainwindow and the dialog. Then when the parent gets deleted the child will be deleted as well. I didn't mention this clearly in the video, sorry about that.

[@Nathan-gd6br]

@@wearesciber No. Parents will delete their children . But in your case Your parent is main windows. In another word, As long as you don't close your application. Your dialogue will remain in memory. Let's say you click the button 10 times You will have 10 dialogue, remain your memory unless you close the whole application

[@wearesciber]

Mmm. Yeah you are right. Thanks for pointing it out.
