QLineEdit setFocus

[bunjee]

Hey there, I'm using that call to set the focus on my QLineEdit widget.

/* virtual */ void ZeConversationWidget::showEvent(QShowEvent * event) 
{
	mConversationInput->getMessageInput().setFocus();
}

/* virtual */ void ZeConversationWidget::showEvent(QShowEvent * event) 
{
	mConversationInput->getMessageInput().setFocus();
}

To copy to clipboard, switch view to plain text mode 

I don't get any focus.
But when I do resize the window, strangely enough the focus is suddenly set on that QLineEdit, and it works.

I'm using 4.4 release candidate.

Has anyone got an idea?

Hi,

From QWidget doc:

Be aware that if the widget is hidden, it will not accept focus until it is shown.

So, if the widget is not shown yet, it don't will get the focus.

For such things use singleShot to set the data values etc, related to showing of widgets etc

QTimer::singleShot(0,this,initialize());
MyWindow::initialize()
{
mConversationInput->getMessageInput().setFocus();
}

Hope this helps

I did a check with isVisible :

/* virtual */ void ZeConversationWidget::showEvent(QShowEvent * event)
{
       if (mConversationInput->getMessageInput().isVisible())
       {
            // My code gets here
            std::cout << "Hello\n";
            mConversationInput->getMessageInput().setFocus();
       }
}

/* virtual */ void ZeConversationWidget::showEvent(QShowEvent * event)
{
       if (mConversationInput->getMessageInput().isVisible())
       {
            // My code gets here
            std::cout << "Hello\n";
            mConversationInput->getMessageInput().setFocus();
       }
}

To copy to clipboard, switch view to plain text mode

Tried that one too, no success. I need to resize my window to get focus.
I think it might be a QT 4.4 bug.
