TableView ProxyModel problem

[norobro]

I don't understand. Do you have two views? One view where the user hides a row and another that shows the highlighted cells. If so you need to hide the row in the view that displays the proxy also.

Maybe something like this in your slot where you hide the row would work:

QModelIndexList list = view->selectionModel()->selectedRows();
foreach(QModelIndex index, list){
    view1->hideRow(index.row());   // view that displays the orgininal data
    view2->hideRow(proxy->mapFromSource(queryModel->index(index.row(),0)).row());  // view displaying proxy model
}
highlightCells();

QModelIndexList list = view->selectionModel()->selectedRows();
foreach(QModelIndex index, list){
    view1->hideRow(index.row());   // view that displays the orgininal data
    view2->hideRow(proxy->mapFromSource(queryModel->index(index.row(),0)).row());  // view displaying proxy model
}
highlightCells();

Or is the user hiding rows in the view showing the proxy?

There is only one view. The highest and lowest value in a column is highlighted in the view. I want the user to be able to remove a row from the view (without removing it from the source) The problem isn't in hiding the row, it is in highlighting the correct row AFTER a row is hidden.
I forgot to show the code for hiding the row;

void DlgPrintPreview::on_btnDeleteRow_clicked()
{
    QModelIndex index = ui->printView->currentIndex();
    if (!index.isValid())
        return;
    ui->printView->setRowHidden(index.row(),true);
    highlightCells();
 
}

void DlgPrintPreview::on_btnDeleteRow_clicked()
{
    QModelIndex index = ui->printView->currentIndex();
    if (!index.isValid())
        return;
    ui->printView->setRowHidden(index.row(),true);
    highlightCells();
    
}

What confused me was this in updateTimeStats():

if (ui->printView->isRowHidden(r)) //Test if user deleted row

if (ui->printView->isRowHidden(r)) //Test if user deleted row

While in createTimerTable() you have:

ui->tableView->setModel(proxy);

ui->tableView->setModel(proxy);

Edit: Attached is a simple app based on one of your earlier (April, I think) posts that demonstrates that what you are trying to do should work.

The code you posted did not work properly If you hide the rows in different orders you get varied results from nothing being highlighted to one item not being highlighted until you click on the table. I think this is close. I have to go to work. I will look closer at your code to see if I can figure out why it isn't working quite right...at least when it is highlighting, it is highlighting the correct number!

On my Linux box the only problem that I experienced was sometimes the highlight didn't show up until the mouse was over the view. Works well otherwise.

See if this fixes things. Add this statement to the MainWindow constructor:

ui->tableView->setSelectionBehavior(QAbstractItemView::SelectRows);

ui->tableView->setSelectionBehavior(QAbstractItemView::SelectRows);

and add an update at the end of the slot:

void MainWindow::pbClicked(){
    QModelIndexList list = ui->tableView->selectionModel()->selectedRows();
    foreach(QModelIndex index, list){
        ui->tableView->hideRow(index.row());
    }
    highlightCells();
    ui->tableView->update();
}

void MainWindow::pbClicked(){
    QModelIndexList list = ui->tableView->selectionModel()->selectedRows();
    foreach(QModelIndex index, list){
        ui->tableView->hideRow(index.row());
    }
    highlightCells();
    ui->tableView->update();
}

Edit: Oops. I see what you mean. It doesn't work if the view is sorted by a different column

[norobro]

I think adding the following statement to the MainWindow ctor and making highlightCells() a slot makes it work properly. The row numbers change on a sort (duh) and need to be rehighlighted.

connect(ui->tableView->horizontalHeader(),SIGNAL(sectionClicked(int)),this,SLOT(highlightCells()));

connect(ui->tableView->horizontalHeader(),SIGNAL(sectionClicked(int)),this,SLOT(highlightCells()));

Thanks....I will try it when I get back home this afternoon!

It is still not always highlighting the cells after rows are hidden. I tried a couple different things for ui->tableview but I am not sure why sometimes it doesn't work. I will look at it some more tonight.

Maybe this will solve it:

void MainWindow::pbClicked(){
    QModelIndexList list = ui->tableView->selectionModel()->selectedRows();
    foreach(QModelIndex index, list){
        ui->tableView->hideRow(index.row());
    }
    highlightCells();
    // ui->tableView->update();
    ui->tableView->setFocus();  // add this
}

void MainWindow::pbClicked(){
    QModelIndexList list = ui->tableView->selectionModel()->selectedRows();
    foreach(QModelIndex index, list){
        ui->tableView->hideRow(index.row());
    }
    highlightCells();
    // ui->tableView->update();
    ui->tableView->setFocus();  // add this
}

That looks like it works!!! I didn't think about setting the focus....Not sure why it needed that but it works. Now to get it to work in my code!

Thanks a million!

[poporacer]

Works great! I had to modify it a bit for my application, but you got me in the right direction!!! Many thanks!!!
