[SOLVED] scrollArea in scrollArea

[A Former User]

Hi all!

I m have class of the category with fixed height
it's two labels, one scroll area and button "show\hide scroll area" plased with layout

when i added to the scrollarea some widgets - the scrollarea blow up self height despite the height of category, respectively widgets show incorrect and gone out the border

why the layout does not interfere?
why setMaximumHeight on the scrollarea doesn't work?

Should you not add it to the layout object and not the scrollarea ?

Maybe you do.

Its hard to give suggestions with no code/pictures.

...hope without code...

void categoryWidget::_initScrollArea()
{
_scrollArea = new QScrollArea;
_scrollArea->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
_scrollArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
_scrollAreaLayout = new QVBoxLayout(_scrollArea);
_scrollAreaLayout->setSizeConstraint(QLayout::SetMinAndMaxSize);
layout()->addWidget(_scrollArea);
}

after i am adding widgets (they can be like this), and now scroll area increas self height ignoring size of the parent where she is placed

solved:

adding widget layer

void categoryWidget::_initScrollArea()
{
_scrollArea = new QScrollArea;
_scrollArea->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
_scrollArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
QWidget* _scrollAreaLayer = new QWidget;
_scrollArea->setWidget(_scrollAreaLayer);
_scrollAreaLayout = new QVBoxLayout(_scrollAreaLayer);
_scrollAreaLayout->setSizeConstraint(QLayout::SetMinAndMaxSize);
layout()->addWidget(_scrollArea);
}

Then scroll bar appears as need

ah. the _scrollAreaLayer does respect the size limits then. Good to know.
