What is "hint" and for what is it good for?

[firen]

Hi,

I have a general question.

There are several properties and methods with the keyword "hint" (for example a sizehint).

Could someone explaine what the typical usage of hint is and for what it is good for?

Thank you :)

@firen Hint is a "recomendation", like here for example: https://doc.qt.io/qt-5/qwidget.html#sizeHint-prop

@jsulm is this the internal used size (or whatevener property) that is used if I dont override it with a setter or something? So is a hint something which comes from the system or shoud/can I set a hint?

@firen Read "Size Hints and Size Policies" in https://doc.qt.io/qt-5/qwidget.html
