[SOLVED] After leaving focus of tableView deselect rows

169Martin

hi, my problem is very simple, when i change tables with TAB, row stays selected in previous tables. i have three tableViews...my app doesnt use mouse. i control it via arrows UP/down, TAB for changing tables and ENTER for activate current row .

My solution:

In your window/widget class you must implement eventFilter(QObject *obj, QEvent *event) function from QObject
and handle the event like this:

@bool MainWindow::eventFilter(QObject *obj, QEvent *event)
{
if (obj == ui->listAlbums) {
if (event->type() == QEvent::FocusIn) {
trackSelection->clearSelection();
return true;
} else {
return false;
}
}

if (obj == ui->listTracks) {
    if (event->type() == QEvent::FocusIn) {
        albumSelection->clearSelection();
        return true;
    } else {
        return false;
    }
}

else {
    // pass the event on to the parent class
    return QMainWindow::eventFilter(obj, event);
}

}
@

listAlbums, listViews are my tableViews

You didn't state what exactly is the problem. I think you mean when you change the focus to another table you want the selected row to disappear right?
Maybe you can use seCurrentCell(-1,-1)

Also there is "this":http://qt-project.org/forums/viewthread/1195 which may be of use

i dont want it dissaper..i need to use "clearSelection()' on the selection of theprevious table, or better, all tables except the one which is focused.

Then use clear selection of the other tables in the cellActivated event of all of the tables
@
cellActivated(int row, int column) [signal]

or similar signals :)

Qt has one nice signal "..entered" but it works only for mouse...such a shame :)
cellActivated works for tableWidget, i have tableViews...

maybe good idea would be re-implement QEvent http://qt-project.org/doc/qt-4.8/qfocusevent.html

then i could catch TAB keypress and clearSelection on the others tableViews

Yes it seems so :) If you think your problem is solved don't forget to edit the title of the thread and add [SOLVED] to the end of it.
