    Default checkboxes

    Below is some code that puts a check box in the first colum of a TableWidget. They are entered nicely in the column, but I have two questions:

    Qt Code:
    1. for (int i = 0; i < list.size(); ++i)
    2. {
    3. fileTable->setRowCount(j+1);
    4. QCheckBox *inserter = new QCheckBox();
    5. fileTable->setCellWidget(j,0,inserter);
    6. }
    To copy to clipboard, switch view to plain text mode 

    1st, how do I align the check boxes to the centre, the only thing i see is for text.

    2nd (and more important), I'm not sure how to acces these now. I want to connect them, so that when one is checked, it sends a signal like:

    connect( checkbox , SIGNAL( toggeled(bool) ), this, SLOT( getType() ) );

    What do I put for checkbox, above? It was created when another signal was called to populate the table.... I'm not sure if I'm being clear.

    Default Re: checkboxes

    The item view framework supports checkable items out of the box. Take a look at QTableWidgetItem::setFlags(). I highly recommend to avoid flooding the table full of item widgets.
    Qt Code:
    1. item->setFlags(item->flags() | Qt::ItemIsUserCheckable);
    To copy to clipboard, switch view to plain text mode

    Thanks for the advice. I actually changed what I was going to do, since only two were going to be selected at a time, I thought maybe drag and drop would be better for the user. It seems to be working, although I'm not sure if I'm doing it the best way. Anyway, thanks!
