Qt5 GUI How To Create QPrintDialog

In this Qt5 GUI article iam going to show you How To Create QPrintDialog

The QPrintDialog class provides a dialog for specifying the printer’s configuration.

The dialog allows users to change document-related settings, such as the paper size and orientation, type of print (color or grayscale),

range of pages, and number of copies to print.

Controls are also provided to enable users to choose from the printers available, including any configured network printers.

Typically, QPrintDialog objects are constructed with a QPrinter object, and executed using the exec() function.

OK now iam going to use my previous article example on How To Create QMenu, and iam going to add a new menu item at name of print like this.

So after that you need to open your .pro file and add print support like this

QT       += core printsupport

1	QT += core printsupport

After adding your .pro file will look like this

QT       += core gui


QT       += core printsupport


greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = QMenu
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

RESOURCES += \
    res.qrc

DISTFILES += \
    print.png

QT += core gui

QT += core printsupport

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = QMenu

TEMPLATE = app

SOURCES += main.cpp\

mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

RESOURCES += \

res.qrc

DISTFILES += \

print.png

OK now right click on your menu item after that choose Go To Slot and from the dialog choose triggered() like this.

Also in your mainwindow.ui we need to add a QTextEdit like this

After that open mainwindow.cpp and in the slot section you need to add this line of code for QPrintDialog.

void MainWindow::on_actionPrint_triggered()
{

    QPrinter printer;

    QPrintDialog dialog(&printer, this);
    dialog.setWindowTitle("Print Document");

    if(ui->textEdit->textCursor().hasSelection())

        dialog.addEnabledOption(QAbstractPrintDialog::PrintSelection);

     if(dialog.exec() != QDialog::Accepted)
         return;




}

void MainWindow::on_actionPrint_triggered()

{

QPrinter printer;

QPrintDialog dialog(&printer, this);

dialog.setWindowTitle("Print Document");

if(ui->textEdit->textCursor().hasSelection())

dialog.addEnabledOption(QAbstractPrintDialog::PrintSelection);

if(dialog.exec() != QDialog::Accepted)

return;

}

So your mainwindow.cpp look like this

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include<QPrinter>
#include<QPrintDialog>


MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}

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

void MainWindow::on_actionPrint_triggered()
{

    QPrinter printer;

    QPrintDialog dialog(&printer, this);
    dialog.setWindowTitle("Print Document");

    if(ui->textEdit->textCursor().hasSelection())

        dialog.addEnabledOption(QAbstractPrintDialog::PrintSelection);

     if(dialog.exec() != QDialog::Accepted)
         return;



}

#include "mainwindow.h"

#include "ui_mainwindow.h"

#include<QPrinter>

#include<QPrintDialog>

MainWindow::MainWindow(QWidget *parent) :

QMainWindow(parent),

ui(new Ui::MainWindow)

{

ui->setupUi(this);

}

MainWindow::~MainWindow()

{

delete ui;

}
