How to set the base widget when subclassing Qt widget

[Cupidvogel]

As I see class MyWidget is inherited from QFrame. So for what is QFrame *baseWidget ?

Yes, that is the problem you see. I want this to be baseWidget. So that the parent of this (or baseWidget) is the parent widget I pass in as parameter. How do I do it?

BaseWidget is positioned in the top left because you gave it the MyWidget instance as a parent and, I am guessing, did not put it in a layout applied to the MyWidget instance. What is the function of baseWidget? Have you put other widgets inside it instead of inside the MyWidget container? It certainly sounds like that from your questions.

Yes, baseWidget will have lots of sub-widgets in it. I pass in the parent because it has to be positioned at a particular position in the parent widget, layout agnostic. If I do

QFrame *baseWidget = new QFrame(this);
baseWidget->setGeometry(x,y,width,height);
//add more widgets to baseWidget

QFrame *baseWidget = new QFrame(this);
baseWidget->setGeometry(x,y,width,height);
//add more widgets to baseWidget

To copy to clipboard, switch view to plain text mode 

in the parent widget code, it works fine. I want to do the same things, except baseWidget will be of type MyWidget that inherits from QFrame.

Are you sure you know what is the classe inheritance ?
Class MyWidget is QFrame too. You do not need field baseWidget and extra WFrame object.

Yes, I know that. I tried this as well:

this->setStyleSheet("background: rgb(246,247,239); border-radius: 5px;");
    this->setParent(parent);
    this->show();

this->setStyleSheet("background: rgb(246,247,239); border-radius: 5px;");
    this->setParent(parent);
    this->show();

To copy to clipboard, switch view to plain text mode 

instead of creating a new QFrame baseWidget. Doesn't work. Doesn't show up at all, unlike the last one where it showed up but not taking the geometry correctly.

Construct MYWidget so that the content you put in baseWidget is its content, and throw away baseWidget, then you will get what you are expecting.
