I use stylesheet property in QtCreator. The flash effect you could probably do with a timer.

ps: googling 'set background QLineEdit' resulted in some decent examples

hey brian, there are couple of ways to do, it all depends on what exactly you need to style.

My experience is using Qt Designer, so if you are familiar with it thats' great - if you aren't, then its a great opportunity for you to have a look at it.



If its for instance to style all QLineEdits and and QTextEdit, open designer...

1. create the UI as needed
2. Right-Click on the top-level object
3. Once you right click, a "set stylehsheet" option should appear
4. just write
".QLineEdit, .QTextEdit
{
background-color: red;
}"
5. and thats it!(images attached for further guidance)

Note: adding the "." before the object name as i did, will make the style to be applied universally to every QLineEdit(or whatever object you choose) in the UI .


thanks,

If you're not using the gui builder, you can do the following:

QLineEdit *edit = new QLineEdit;
QPalette p = edit.palette();
p.setColor(QPalette::Base, Qt::red);
edit->setPalette(p);

QLineEdit *edit = new QLineEdit;
QPalette p = edit.palette();
p.setColor(QPalette::Base, Qt::red);
edit->setPalette(p);

To copy to clipboard, switch view to plain text mode 

Look at the documentation for QPalette too.
