display image and get coordinates

[wysota]

I would suggest you start with something simpler. Like at least following some of the tutorials and examples Qt has.

[ready]

can you please provide the link for latest Qt GUI application tutorial

[wysota]

All materials are available in the reference manual, either offline or online.

[ready]

atleast tell me which ui tool is used for image displaying

[Archa4]

I think u can use QLabel->setPixmap(...)

[ready]

As u suggested i used label which is in display widget..
my code:

void MainWindow::on_pushButton_2_clicked()
{
QPixmap *img = new QPixmap("freedom.jpg");//this image is in folder that contains exe
ui->imagelabel->setPixmap(*img);//named the label as imagelabel
ui->imagelabel->show();
 
 
}

void MainWindow::on_pushButton_2_clicked()
{
QPixmap *img = new QPixmap("freedom.jpg");//this image is in folder that contains exe
ui->imagelabel->setPixmap(*img);//named the label as imagelabel
ui->imagelabel->show();


}

To copy to clipboard, switch view to plain text mode 

but this does not show error and neither it displays the image ............please help

[Archa4]

Well... here is the code i used:

QImage image("C:/Picture.jpg");
imageLabel->setPixmap(QPixmap::fromImage(image));

QImage image("C:/Picture.jpg");
imageLabel->setPixmap(QPixmap::fromImage(image));

To copy to clipboard, switch view to plain text mode 

And I didn't used the ui thing, so I really can't help there...

[ready]

thank you Archa4.....It really worked....
I would like to ask one more question...is it possible to get the co-ordinates from the picture displayed in label just by clicking with mouse ....ie mouse handling....
I have got no idea how to do it in qt please help

[Archa4]

Well... I found another thing in documentation:
http://doc.trolltech.com/4.7/qwidget.html#pos-prop

It shows the position of a widget within the parent's widget.

I think u can use it like
QPoint point = imagelabel->pos();

But i cannot be sure...
