How to disable text entry

Anonymous_Banned275

I have a small issue with my C++ code .

My base class is QTextEdit - to that class I add QWidget - user access to application.
Works as desired.

The "problem" is - the added widget DOES NOT fully covers the underlying "add text feature " to the original display.
The user can enter any text into the form at any point.

I would like to disable the "flashing " | mark thus disable the random position text entry marker at the same time.

I cannot simply remove the "newFile" code - it is used to keep track of the MDI subwindows.

Addy reasonable suggestion how to do this - disable the text entry - would be appreciated

        //orignal createMdiChild
        MdiChild *child = createMdiChild(); //QTextEdit
        child->setLayout(new QVBoxLayout);
        DeviceDiscoveryDialog *DDD = new DeviceDiscoveryDialog();
        // insert widget
        child->layout()->addWidget(DDD);
       child->newFile();  // create child as file - need file name
        child->show();     // show added widget and original child

Is this what you are looking for?

Edit:
I read it a few times. Not getting what you need. Would a picture help?

Here is a screenshot with no text entries , but the flashing "|" symbol - upper left corner - is where text can be added

Here is after "k" was pressed for a while

Obviously goofy thing to let user do.

Which object can I make "read only"?

There may be an occasion to have "plain" child submenu , no widget added, so adding text would be OK.

Hence it should be controlled outside child class.

As simple as this
child->setReadOnly(true);

Thanks for resolving the problem.
