[PyQt] Why lineEdit is showing text like this ??

[scorp08]

The below code is showing lineEdit such that when a text is written, it showed the text not throughout of the width of the lineEdit. Kind of seemed like it is divided by half.

Based on my try and errors, the cause is

self.lineEdit=lineEdit(ui.lineEdit)

to initialize the mainwindow.
Any Help would be great
Thnks :)
