changing QPushButton label

[Ferric]

Hi,

I am trying to find a way to change the text displayed on a button, currently I have created a button:

QPushButton *uploadButton = new QPushButton(tr("Upload To Unit number one"));

QPushButton *uploadButton = new QPushButton(tr("Upload To Unit number one"));

To copy to clipboard, switch view to plain text mode 

and once I have clicked this button, I would like the button label to be changed to something like

"Upload To Unit number two"

"Upload To Unit number two"

To copy to clipboard, switch view to plain text mode 

I know I can use something like:

uploadButton->setText("upload to unit number two");

uploadButton->setText("upload to unit number two");

To copy to clipboard, switch view to plain text mode 

But when I put this in a slot that is activated by the signal emitted by the uploadButton, my application just quits,

I think maybe I have to declare the uploadButton as a "Global" widget( if you know what I mean), but I'm not sure how to do this..


Any advice appreciated, Thanks
