@Flesh Romha Korev on stackoverflow.com gave me this answer:

onSortIndicatorColumnChanged: tableView.model = (sortIndicatorColumn == 0) ? myListModel1 : myListModel2 onSortIndicatorOrderChanged: tableView.model = (sortIndicatorColumn == 0) ? myListModel1 : myListModel2

but in MouseArea in row delegate styleData.row - available
following code show right click menu for row in place where mouse clicked

rowDelegate: Rectangle { id: rdRow height: 30 MouseArea { id: maRow anchors.fill: parent acceptedButtons: Qt.RightButton onClicked: { console.log("right click on row", styleData.row, mouseX, mouseY, tvMain.flickableItem.contentY) if ((styleData.row || (styleData.row === 0)) && (mouse.button === Qt.RightButton)) { currentRowIdxForMenu = styleData.row cmRow.x = mouseX cmRow.y = mouseY + styleData.row * rdRow.height - tvMain.flickableItem.contentY cmRow.open() } } } }

I have download the source code. And find no use of the param row. So it's redundant.

Close the question, thanks!

Hi,

Add a setter to your model that is Q_INVOKABLE and pass your query through it. Don't forget to add proper error checking to give feedback to your user if something goes wrong.

What was the problem ?

Hi,

More likely that not all your database data are loaded in memory. You would have to call fetchMore however beware that if you have big tables it's going to cost you more in RAM.

Thank you for sharing!

@raven-worx said in QCompleter in QTableView: show always, even before user input:

declare the m_Editor variable as mutable.

This makes it compile (even though I'm not sure about the implications), but it doesn't help me: there is no Show event handled in editorEvent ever (tested with printf-debugging - yes, before the test for QLineEdit), I'm only getting Mouse events.

@SGaist said in QCompleter in QTableView: show always, even before user input:

Something like completer->popup()->show(); should do what you want.

Nope, does not help.

I figured (using qDebug, again), the place where I should put my popup-opening call is setEditorData. In there, I receive the QLineEdit and it's QCompleter: But I cannot make it show the popup. I tried now:

completer->setCompletionPrefix(index.data(Qt::EditRole).toString()); completer->complete(); completer->popup()->show();

Note: Sometimes the popup is shown for a very short time, but immediately hides. When repeatedly entering & leaving edit mode this only works the first time.

Sounds great, but I get some runtime error:

QPainter::begin: Paint device returned engine == 0, type: 2 QWidget::render: Cannot render with an inactive painter

Edit:
There is some modification on your suggested code neccessary:

const QModelIndex& index = currentIndex(); // Render the pixmap QPixmap pixmap(visualRect(index).size()); //pixmap. render(&pixmap, QPoint(), visualRect(index)); // Create the drag QDrag* drag = new QDrag(this); drag->setPixmap(pixmap); ...

But anyhow it renders the cell of one index above the selected one.
Maybe that has something to do with the offset parameter (second one in render).

Edit2:
The proper QRect can be calculated with the height of the horizontal header:

render(&pixmap, QPoint(0,0), visualRect(index).translated(0, horizontalHeader()->height() ));

Thanks everyone

@cheezus
JavaScipt source doesn't leak now.but QML side still leaks.please .

@PhTe flickableItem is your friend here. It could be done as follows:

//Inside some TableView flickableItem.onContentYChanged: { mirror.flickableItem.contentY = flickableItem.contentY //mirror = id of other table }

@yxlee Hi! Did I get this right: You've got a window. To that window you've added a QScrollArea with some content. You also added some other widgets to that window. Now you want these other widgets to move when you scroll inside the scroll area?

Thanx Ratzz.

Hi @Bioniwulf,
Did you try creating them dynamically using addTab. Do it as soon you as you receive UDP data.

@_compiler

Model *derived = static_cast<QSqlQueryModel*>(model);

This isn't a valid cast because you can't implicitly cast to a derived type (see @mrjj's comment).

Model *derived = static_cast<Model *>(model);

Is valid but unsafe, as @SGaist pointed out.

Ultimately, what is not working?

If you use a QAbstractListModel the data() will be accessed on demand only (tested).
TableView will reuse delegates when scrolling up/down and not create new ones (according to description)

Sounds pretty crazy...

I got a solution on SO: I should've used "height" instead of height inside PropertyAnimation.

@SGaist Yes. I managed to do using a Grid, since it was not possible to make the tableview. Now I have my view, but i was looking at the GridView doc, but dont know... if is better keep the current code or try something different.
This is my actual qml code:

import QtQuick 2.5 import QtQuick.Controls 1.4 import QtQuick.Window 2.2 ApplicationWindow { visible: true width: Screen.width /2 height: Screen.height /2 Grid { id : tabuleiro columns: 10 rows: 10 anchors.fill: parent spacing : 1 Repeater { delegate : Rectangle { width: Math.min(tabuleiro.width, tabuleiro.height) / 10 height: width color : isWater ? "blue" : "red"; } model : myModel; } } }

Finally I solved it!!!

function fillRow() { table.model = undefined // <--- 1 if (!tableModel.count) { tableModel.append({"C0":50}) } else { tableModel.setProperty(0,"C"+(table.columnCount-1),50+table.columnCount-1) } table.model = tableModel //<--- 2 var x = tableModel.get(0) console.log("Num. Columns",table.columnCount,"row object",JSON.stringify(x)) }

When I fill the columns, I set TableView.model to undefined(1), then fill the rows, and after I set TableView.model to ListModel again(2)

I like it when you do QtQuick !

Hi, I finally got the latest 5.6.0 baseline compiled for iOS and can confirm that 5.6.0 does not show this tableview error.

Thanks for your help, well appreciated !!

BR,

Your two images show two different tables. Are you sure that both tables contains data ?

Thank you. It worked!

You would at least need two radio buttons for that. But it sounds a bit unusual for a UI especially for a database.

Sounds like you want to use both a custom widget using QDataWidgetMapper and a QTableView at the same time.

SOLUTION:

ui->tableView->model()->setHeaderData(2,Qt::Horizontal,QFont("Arial",10,QFont::Bold),Qt::FontRole);

Actually everything is stated in the Qt Help, - just need to know how to correctly use it :)

Thank you. It worked.

Thank you. It worked.

Thank you.

Thank you all. It finally worked.
