Guide
- qt: 5.7.0
- qmake: 3.0 based on Qt 5.7.0
- qtcreator: 3.5.1 based on Qt 5.5.1
purge existing qt5 and qt4
sudo apt-get purge qt5-default qtcreator
sudo apt-get purge qt4-designer qt4-dev-tools
install qt57
In addition, building graphical Qt applications requires OpenGL libraries and headers installed. On Ubuntu and other Debian-based Linux systems you can get OpenGL and the minimal set of development tools by installing the packages libgl1-mesa-dev and build-essential, i.e. by running this command:
sudo apt-get install build-essential libgl1-mesa-dev
Download qt and install.
sudo apt-get install build-essential libgl1-mesa-dev
wget http://download.qt.io/official_releases/qt/5.7/5.7.0/qt-opensource-linux-x64-5.7.0.run
chmod +x qt-opensource-linux-x64-5.7.0.run
./qt-opensource-linux-x64-5.7.0.run

Qtcreator Tutorial
install qtcreator
sudo apt-get -y install qtcreator
qtcreator -version
Qt Creator 3.5.1 based on Qt 5.5.1
create application
Start qtcreator
and create a Qt Widget Application
named hello
.
add resource file
Add a resource file named resource.qrc
.
hello-->right click--> Add New... --->qt---> qt resource file---> name resource---> generate resource.qrc
and then import images to resource.qrc
Resources | resource.qrt--->right click---> Add Prefix...---> name /prefix
Resources | resource.qrt | /prefix--->right click ---> Add Existing Files... ---> choose images ---> OK
use resource in mainwindow.ui
button ---> property page ---> icon ---> Choose Resource... ---> select image ---> OK
Qt slots
method 1
steps:
mainwindow.ui ---> choose button ---> right click ---> Go to slot... ---> choose clicked() ---> OK
will add slots in mainwindow.h
automatically
private slots:
void on_pushButtonOK_clicked();
and in mainwindow.cpp
void MainWindow::on_pushButtonOK_clicked()
{
}
Tips: if we use on_pushButtonOK_clicked
style, there is no need to connect with slots in MainWindow
constructor by hand.
method 2 (OK)
add slots in mainwindow.h
by hand
private slots:
void pushButtonCancel_clicked();
and in mainwindow.cpp
void MainWindow::pushButtonCancel_clicked()
{
}
connect button with slot in mainwindow.cpp
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
// connect
connect(ui->pushButtonCancel, SIGNAL(clicked()), this, SLOT(pushButtonCancel_clicked()));
}
