Reduce Vertical Spacing of My Content in QGridLayout

Phamy1289

I have the space marked that I want to reduce. The code show's what I've done. Is there a way to reduce the top space even more?

    QGroupBox *pGroupBox = new QGroupBox;
    pGroupBox->setStyleSheet("background:gray");

    QGridLayout *pGridLayout = new QGridLayout;
    pGridLayout->setSpacing(0);
    pGridLayout->setMargin(0);

    QLabel *pHeader = new QLabel(this);
    QFont headerFont("times", 18);
    headerFont.setBold(true);

    pHeader->setFont(headerFont);

    pHeader->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Fixed);
    pHeader->setAlignment(Qt::AlignCenter);
    pHeader->setText("Details");
    pHeader->setStyleSheet("QLabel {color:white;}");

    QDateTime *myDateTime = new QDateTime;
    QDate *myDate = new QDate;

    myDate->setDate(2018, 3, 28);
    myDateTime->setDate(*myDate);
    myDateTime->setTime(QTime::currentTime());

    mpStartDateTime = new QDateTimeEdit;
    mpStartDateTime->setDisplayFormat("yyyy-MM-ddThh:mm:ss");
    mpStartDateTime->setStyleSheet("color: white;"
                                   "border:0");
    mpStartDateTime->setReadOnly(true);
    mpStartDateTime->setAlignment(Qt::AlignLeft);
    mpStartDateTime->QAbstractSpinBox::setButtonSymbols(QAbstractSpinBox::NoButtons);

#ifdef QT_DEBUG
    mpStartDateTime->setDateTime(*myDateTime);
#else
    mpStartDateTime->setDateTime(QDateTime::currentDateTime());
#endif

    mpCloseDateTime = new QDateTimeEdit;
    mpCloseDateTime->setDisplayFormat("yyyy-MM-ddThh:mm:ss");
    mpCloseDateTime->setStyleSheet("color: white;"
                                   "border:0");
    mpCloseDateTime->setDateTime(QDateTime::currentDateTime());
    mpCloseDateTime->setReadOnly(true);
    mpCloseDateTime->setAlignment(Qt::AlignLeft);
    mpCloseDateTime->QAbstractSpinBox::setButtonSymbols(QAbstractSpinBox::NoButtons);

    QLabel *pStartDateLabel = new QLabel("Start Date");
    pStartDateLabel->setStyleSheet("QLabel {color:cyan;}");
    pStartDateLabel->setAlignment(Qt::AlignCenter);
    QLabel *pEndDateLabel = new QLabel("End Date");
    pEndDateLabel->setStyleSheet("QLabel {color:cyan;}");
    pEndDateLabel->setAlignment(Qt::AlignCenter);

    pGridLayout->addWidget(pHeader, 0, 0, 1, 4);
    pGridLayout->addWidget(pStartDateLabel, 1, 0);
    pGridLayout->addWidget(mpStartDateTime, 1, 1);
    pGridLayout->addWidget(pEndDateLabel, 1, 2);
    pGridLayout->addWidget(mpCloseDateTime, 1, 3);
    pGroupBox->setLayout(pGridLayout);

@Phamy1289 said in Reduce Vertical Spacing of My Content in QGridLayout:

grid->addWidget(QDateTime, 1, 0)

This will not compile

Create your ui in the designer. I would guess the size policy is not properly set or the complete widget is not in a proper layout (with e.g. an expanding vertical spacer).

@Christian-Ehrlicher Sorry, I was just trying to have my code a bit easier to read. I've changed it to show the whole code.

Hi,

Is your picture showing only your group box ?

Phamy1289

@SGaist Yes, it's showing only the groupbox and the contents in it

Your code displays nothing.
pGroupBox seems to go nowhere ...

Where do you put the groupBox ?

Adding the following seems to work - for me :)

auto layout=new QHBoxLayout;
layout->addWidget(pGroupBox);
layout->setContentsMargins(0,0,0,0);
setLayout(layout);

It's in my main function.

    QPalette backgroundColor(palette());
    backgroundColor.setColor(QPalette::Background, Qt::black);

    QGridLayout *pGrid = new QGridLayout;
    QWidget *pBaseWidget = new QWidget;

    pBaseWidget->setAutoFillBackground(true);
    pBaseWidget->setPalette(backgroundColor);
    pBaseWidget->setSizePolicy(QSizePolicy::MinimumExpanding, QSizePolicy::MinimumExpanding);
    pBaseWidget->setMaximumWidth(800);

    pBaseWidget->setLayout(pGrid);
    setWidget(pBaseWidget);

    //Other Stuff...

    pGrid->addWidget(myGroupBoxDateTime, 0, 0, 1, 2);

add QSpacerItem into QGridLayout at the bottom to push all widgets up
void addItem(QLayoutItem * item, int row, int column, int rowSpan = 1, int columnSpan = 1, Qt::Alignment alignment = 0)

or try to align widgets to top
void QGridLayout::addWidget(QWidget *widget, int fromRow, int fromColumn, int rowSpan, int columnSpan, Qt::AlignTop )

@JoeCFD Thank you, adding the QSpacerItem did the trick.
