Resizing the widget(listwidget)

[Kinesis]

Hi there, I would like to resize my whole widget(listwidget and it contains other sub widgets) to get appropriate size(1366x768) when I click the maximize .And if I click the minimize it will go back to some limited size(like 640x480) . How can I fix that here is my current code.

 auto label = new QLabel();
    label->setMinimumHeight(30);

    auto listWidget = new QListWidget();
    listWidget->setMinimumSize(1366,768);

    auto listWidget_dirList = new QListWidget();
    // listWidget_dirList->setMinimumSize(150,100);
    listWidget_dirList->setMinimumWidth(150);

    auto listWidget_main = new QListWidget();
    listWidget_main->setFlow(QListView::LeftToRight);
    listWidget_main->setMinimumSize(1100,768);
    listWidget_main->setGridSize(QSize(360, 360));
    listWidget_main->setResizeMode(QListView::Adjust);
    listWidget_main->setViewMode(QListView::ListMode);
    listWidget_main->setWrapping(true);

    auto button = new QPushButton();
    button->setText("Load Dir");
    button->setMinimumHeight(30);

    auto    item = new QListWidgetItem("",listWidget);
    auto    widget = new QWidget;
    auto    vb = new QVBoxLayout;
    auto    vb1 = new QVBoxLayout;
    auto    hb = new QHBoxLayout;

    vb->addWidget(button);
    vb->addWidget(listWidget_dirList);

    vb1->addWidget(label);
    vb1->addWidget(listWidget_main);

    hb->addLayout(vb);
    hb->addLayout(vb1);

    widget->setLayout(hb);
    widget->setMinimumSize(1366,768);
    listWidget->setItemWidget(item,widget);
    listWidget->show();

@Kinesis said in Resizing the widget(listwidget):

listWidget->setMinimumSize(1366,768);

Why? It should be resizeable, right?

widget->setMinimumSize(1366,768);

Again: why?

Your "widget" isn't in any layout as far as I can see. And did you call widget->show() somewhere?

"Why? It should be resizeable, right?"
Ans:: Yes it should be resizeable.So I just need to unable this resize function?

"Your "widget" isn't in any layout as far as I can see. And did you call widget->show() somewhere?"
Ans:: I add label , button , listwidget_dirlist and listwidget_main on listWidget . And I call listWidget->show();

@Kinesis I don't think you need these setMinimumSize(1366,768).

" I add label , button , listwidget_dirlist and listwidget_main on listWidget . And I call listWidget->show();" - I'm talking about "widget" variable, not listWidget.

As you can see in the code I said variable "auto listWidget = new QListWidget" .

@Kinesis

auto    widget = new QWidget;

Ahh ok. How can I resize the vertical box ? I want its width to be thinner that I can see slider bar . When I use 1366x768 the vertical box vb(variable) becomes wider and I can't see the slider which is at the right edge of my widget.

When I use 1366x768

Why do you set 1366x768?
If you're using layouts properly there is no need for that.
I already asked before: did you put widget in a layout?
