[Qt-interest] QFontMetrics and StyleSheet

[hi]

 Hi,

Herewith I have attached a toy program in which it sets the stylesheet "* {
font-size: 20pt; }" of app context.

After setting above style sheet, I am taking QFontMetrics to do some
processing on fontmetrics.width() / fontmetrics.height() but both are
getting wrong.

In toy program if you click "Print Font Info" button, I displays the correct
information.
But when showing the fontmetrics of dialog (click on 'Show Dialog') or panel
(click on 'Show Panel') it displays wrong.

In short: my aim is to set application font and subsequently I should get
the correct fontmetrics info.

Please let me know if I am doing anthing wrong.

Thank you in advance.
