Disable or lock a QTableWidget

[grub87]

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?

[grub87]

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

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

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

To copy to clipboard, switch view to plain text mode

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

[grub87]

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:

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

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

To copy to clipboard, switch view to plain text mode 

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".

[grub87]

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

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

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

To copy to clipboard, switch view to plain text mode

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

[grub87]

I can still edit the items of the table

Works fine for me:

// 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();
}

// 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 , that's why anything i put in the .cpp didn't work. THANKS FOR ALL THE HELP!!!
