qtablewidget

I am trying to design something like a timeline view for my video player. I decided to use QTableWidget as the timeline since it suits my purpose. My widget looks like this: I want the green line to run through the widget when i click on play. Here is my MVCE example: //View.cpp View::View(QWidget* parent) : QGraphicsView(parent) { QGraphicsScene* scene = new QGraphicsScene(this); TableWidget* wgt = new TableWidget; scene->addWidget(wgt); QGraphicsLineItem* item = new QGraphicsLineItem(30, 12, 30, wgt->height() - 9); item->setPen(QPen(QBrush(Qt::green), 3)); item->setFlags(QGraphicsItem:

I am using Qt on two ubuntu machines and am copying the source code from time to time between them. I found a really annoying problem when doing that and I can't figure out why this happens. I am using a table Widget to display some data and want to stretch the horizontal header to fit the content length. To do that I use the following line: ui->tableWidget->horizontalHeader()->setResizeMode(0, QHeaderView::ResizeToContents); This works just fine. I have a few of this codelines. However, when I now copy over my source code to the other PC to work on it, I get the following compile error:

I have QTableWidget with CheckBoxes in some cells. I want to disable user to perform mouse click over the table cells (so he can't change checkBox state) for some time while I am using data from the table. I've tried table.setDisabled(1) but that disables whole table and I need scroll to be enabled. Any help would be appreciated. EDIT To be more precise: there could be up to 15x3000 cells in table, filled with text(editable), checkbox(checkable), svg graphic(opens other window when double click on it) or some custom widgets(which also have clickable or editable parts). I need to disable user

I'm developing some tool in PyQT4 and Python 2.7 and I stuck in a little problem. I've 3 buttons in stored in widget and that widget is in cell in the table (QTableWidget). So my problem is that I can't align widget to top of cell and tool doesn't resize row height to defined in widget minimum/fixed height. Here is how it looks now with method resizeRowToContents. And I want something like this I did something similar with fixed row height but its not the way I want. I solved this problem in quite simply way. First of all I changed margin of layout to 0px (later I changed that to 3px to have

I tried: QTableWidget *j = new QTableWidget (10000, 5, centralWidget); j->setColumnWidth (0, 500); j->setColumnWidth (1, 30); j->setColumnWidth (2, 30); j->setColumnWidth (3, 320); j->setColumnWidth (4, 310); j->setWordWrap (true); Also tried resizeColumnsToContents and resizeRowsToContents , but failed. If the text is longer than the set width, I want the sentence to break down. Currenty, the lengthy part of the sentence just doesn't get shown. setWordWrap defines the behaviour of the text, without altering column size. If you need to keep column width fixed, call resizeRowsToContents after

How would I go about limiting the rows/columns selected in a QTableWidget? I need to force the user to use a contiguous selection (already done) to select exactly two columns and any amount of rows. Thanks! You will probably have to do one of 2 things: You would have to subclass QItemSelectionModel and implement functions for adding and deleting selected QModelIndex es so that you only add items from 2 rows to it. You can do this by having a custom implementation for catching signals that QItemSelectionModel emits such as: connect(tableWidget->selectionModel(), SIGNAL(selectionChanged
