QScrollarea in verticalLayout

@hjohn said in QScrollarea in verticalLayout:

QScrollArea *area=new QScrollArea(this);
area->setLayout(ui->verticalLayout);

because thats not how you set content to a QScrollArea.
You should use QScrollArea::setWidget()

#include<QScrollArea>
#include<QPushButton>
#include<QDebug>
Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);

    QWidget *W=new QWidget(this);
    
    W->setLayout(ui->verticalLayout);



    QScrollArea *area=new QScrollArea(this);
        area->setWidget(W);

}

Widget::~Widget()
{
    delete ui;
}

define proper. What exactly do you want to achieve?

[hjohn]

@raven-worx Proper:Without horizontal scrollBar, I mean if we want to see the whole button we have to scroll . I don't want to scroll horizontally.

[hjohn]

Okay its done ,
I just resized the QScrollArea.
Thanks all.

Hi,

Since you are using Designer, why don't you put the QScrollArea directly in your ui ?

[hjohn]

@SGaist I had to implement the QScrollArea by means of code.

[SGaist]

Why is that ?

[hjohn]

@SGaist Firstly I used the ScrollArea from UI, and it worked fine, So I wanted use QScrollArea by code. Just for learning purpose.

[SGaist]

Then I'd recommend to start by doing the whole interface in code only. Once you are confortable with that, you can start mixing designer and code generate widgets.

There are subtleties when mixing that you have to take into account.

@SGaist yeah thanks..
