Disable or lock a QTableWidget

Hi i'm working with a QTableWidget and want to disable or lock the edition of it. I know that a QTableView would do the trick, but i'm working with an open source project that has this "issue", because this table is big, it would take me a lot of time to start working with a QTableView. THANKS IN ADVANCE

The most straight forward way, for the whole view:

• QAbstractItemView::setEditTriggers()
• QAbstractItemView::NoEditTriggers

A bit more tedious way, adjusting the flags for individual items:

• QTableWidgetItem::setFlags()
• Qt::ItemIsEditable

Hi thanks for your advice, but i don't know how to implement your answers could you give a head start on that please.

What did you try so far?

I thought i would be a property or function of my QTableWdiget object, for example:

Code:

---

object->setEditTriggers(); //This tells me that inside the () goes a EditTriggers
                object->editTriggers();

---

Yes, it is a property. There is a getter that returns the current edit triggers in use, and there is a setter which you can use to change the edit triggers. Don't you think the setter would perhaps take a parameter, like suggested by your compiler? Not to be rude, but perhaps it's time to get back to your favourite C++ book for a while?

PS. Here's the link to the documentation once more, because the first one seemed to be broken: QAbstractItemView::editTriggers

Yes every object has a getter and a setter, the setter obviously needs a parameter, but i was refering to how you put the EditTriggers, i put it like this:

Code:

---

ui.diariostableWidget->setEditTriggers(QAbstractItemView::EditTriggers(0));

---

But it doesn't work.

That should work, but for better readability (and safer code) you should use the corresponding enum value called "no edit triggers".

Hi again, i tried to use the NoEditTriggers like this but it doesn work either:

Code:

---

ui.diariostableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);

---

But what do you mean by "doesn't work"? Please try to be more specific.

I can still edit the items of the table

Works fine for me:

Code:

---

// main.cpp
#include <QtGui>
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QTableWidget table(4, 4);
    // uncomment the following line and the table can no more be edited:
    // table.setEditTriggers(QAbstractItemView::NoEditTriggers);
    table.show();
    return app.exec();
}

---

I think it doesn't work because in the part of the options of tha visual form in editTriggers the options of editing with double click was checked, i noticed the existance of this option until now :o, that's why anything i put in the .cpp didn't work. THANKS FOR ALL THE HELP!!! :)
