application window size control

applefier

How do I prevent the application window from getting resized by its layouts/widgets but allow it to be resized by the user using mouse or the maximize button?

Thanks.

Hello @applefier ,

To fix the size of your layout you can use

the setSizeConstraint ( SizeConstraint ) function

and you have to put QLayout::SetFixedSize as arg of SizeConstraint

Here is the doc explanation:

sizeConstraint : SizeConstraint

This property holds the resize mode of the layout.

enum QLayout::SizeConstraint

The possible values are:

Constant	Value	Description
QLayout::SetDefaultConstraint	0	The main widget's minimum size is set to minimumSize(), unless the widget already has a minimum size.
QLayout::SetFixedSize	3	The main widget's size is set to sizeHint(); it cannot be resized at all.
QLayout::SetMinimumSize	2	The main widget's minimum size is set to minimumSize(); it cannot be smaller.
QLayout::SetMaximumSize	4	The main widget's maximum size is set to maximumSize(); it cannot be larger.
QLayout::SetMinAndMaxSize	5	The main widget's minimum size is set to minimumSize() and its maximum size is set to maximumSize().
QLayout::SetNoConstraint	1	The widget is not constrained.

Hope this will work,

Regards !
