@Torsten-S. No problem. Have a nice day!

@Bidski Hi Not in Qt. ( maybe if old) I would guess from the attempt to snap the coordinates but cant say for sure. However, please see this sample https://www.dropbox.com/s/gp9rvylkb18xnl3/myrubberband.zip?dl=0 [image: Cqi71U.png] Drag the rubberband and release It cuts what is expected and show in label So all seems to be fine :) #include <QMouseEvent> MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); move_rubberband = false; rubberBand = new QRubberBand(QRubberBand::Rectangle, this); rubberBand->setGeometry(0,0,50,50); rubberBand->show(); } void MainWindow::mousePressEvent(QMouseEvent *e) { if(rubberBand->geometry().contains(e->pos())) { rubberband_offset = e->pos() - rubberBand->pos(); move_rubberband = true; } } void MainWindow::mouseMoveEvent(QMouseEvent *e) { if(move_rubberband) { rubberBand->move(e->pos() - rubberband_offset); } } void MainWindow::mouseReleaseEvent(QMouseEvent *e) { move_rubberband = false; QRect r=rubberBand->geometry(); rubberBand->hide(); QPixmap p=grab(r); // no need for mapTo here. ui->label->setPixmap(p); rubberBand->show(); rubberBand->raise(); }

@isan You are welcome :)

Thank you for your time SGaist, have a nice day.

I think I found the answer http://doc.qt.io/qt-5/licenses-used-in-qt.html

@o6a6r9v1p Got the problem, the label is to declared public. it is working fine. Thanks to all

thank. That's what I thought

You're welcome ! Since you have it working now, please mark the thread as solved using the "Topic Tools" button so that other forum users may know a solution has been found :)

I'd recommend rather implementing your own list model based on the drag and drop model described here. That will likely make your implementation simpler and cleaner.

@mrjj said in QTableView shows nothing: @t0msk Yes You do QSqlQueryModel query; .. ui->tableView->setModel(&query); Here you use & to take adress of it. So as soon as function ends query is deleted and view is empty. You could move QSqlQueryModel query; to .h file. as member in mainwindow Ah, thank you for explanation :)

Hi Can you provide some code and details about platform and Qt version. "kosomkooooooooooooooooooooooooooooooooooooooooooooo" is not particular useful :)

You aren't working on Windows, are you ? Because, in the detailed description there's a note stating that it's a feature not supported on Windows platform.

To be completely frank, I'd just have a session object where I have the socket and whatever's needed for the communication. So your original question is a bit unusual from my perspective. For example you could take a peek here and here.

I got it to work with a const_cast ...

At last I found it! I had it like this: int row = mapper->currentIndex(); Replaced with: int row = model->rowCount(); and works fine!!

But the model>isDirty() remains true... How can I make it become false? I tried: mapper->submit(); model->submitAll(); model->submit(); but they fail. EDIT: model->revertAll() seems to set isDirty to false.

Yep, it works. Thanks :)

hi i would try stream << "TEST TEST"; and see.
