stylesheet question

[gt.beta2]

Hi,
Imagine i have a Dialog (myDialog) with 3 QLineEdit objects: lineEdit1, lineEdit2, lineEdit3. I am using QtDesiner so i have 4 files:

• main.cpp
• myDialog.h
• myDialog.cpp
• myDialog.ui

If i want to apply a red color to the background off all lineEdits in the application e use, in main.cpp the following:

app.setStyleSheet("QLineEdit { background-color: red }");

app.setStyleSheet("QLineEdit { background-color: red }");

To copy to clipboard, switch view to plain text mode 

Now supose i want to apply other stylesheet color as the Dialog level. Where showld i place the code:

myDialog->setStyleSheet("QLineEdit { background-color: yellow }");

myDialog->setStyleSheet("QLineEdit { background-color: yellow }");

To copy to clipboard, switch view to plain text mode 

?
Thanks
