Is possible to set a minimum width to a widget became visible using CSS or editing her properties in Qt Designer?

In this example the Pink QWidget has her Horizontal and Vertical policy set to Ignored so it can be completely 'resized' to the minimum size, which is 0.

How I can set a 'minimum visible width' to the PushButton became visible?

I created this gif to illustrate what I'm talking about:

As seen in the gif the PushButton became visible as soon as her parent becomes visible (default behavior), I would like to make it visible only when there's a specific amount of space in the parent.

I wonder if this could be achieved with any kind of CSS similar to:

     min-width: 0;
     max-width: 200;
     /* min-visible-width: 100; */ <- example

or by editing the button/parent properties in the Qt Designer, instead of subclassing the button and setting it hidden/unhidden according to her size.

Hi,

AFAIK, no.

You should re-implement your purple widget to handle the button as an invisible widget will not resize even if its containing widget does.
