I can pass a QWidget* pointer to a function, no issue. My question is, how do I pass the actual QWidget function / option?

For example – this is how I clear a QWidget in C++ code:

ui->textEdit->clear();

I can pass the ui->textEdit object, but I do not know how to pass such object parameters to be able to execute ui->textEdit->clear(); in pseudocode to execute the passed object and its parameter.

This is not a “try this and try that” question. I need some theory on how to pass an object and its parameters.
