Difference between max size, best size and min size ? Topic is solved

[Rocketmagnet]

Hi all,

Reading about sizers ... a windows seems to have a min size, best size and max size.

Min and max size seem to be pretty obvious, what's exactly is the point of the best size?

My guess would be that, if there's plenty of room available, then don't make it bigger than the best size. In which case, there's no need for a max size.

Many thanks

AFAIK the best size is the preferred size of the control. When you call wxWindows::Fit() on the parent window, it tries to honour this best size.

When the user resizes the parent windows, the minimum and maximum size is limited by the min and max sizes of the controls.

Try here:

It's wxPython, but it doesn't make much difference

HTH.

Thanks Infinity_77,

That's pretty helpful.

So, is this correct:

Min and Max size are used when it's the outer window whose size is being set externally (for example by the user dragging it). The Min size prevents the user making the window smaller than that. Similarly with Max size.

Best size is used when the outer window is told to automatically resize itself to whatever size would be best for its children.

I.E. Min and Max are used when size information is flowing from parent to child. Best size is used when size information is flowing from child to parent.
