QTextBrowser help please!

[munna]

Hi

Please have a look at the following 2 pieces of code.

ExplainBrowser b;//QTextBrowser
b.setText(str);
//b.show();
int eHeight = b.contentsHeight();//wrong height
int eWidth = b.contentsWidth();//wrong width

ExplainBrowser b;//QTextBrowser
b.setText(str);
//b.show();
int eHeight = b.contentsHeight();//wrong height
int eWidth = b.contentsWidth();//wrong width

To copy to clipboard, switch view to plain text mode 

ExplainBrowser b;//QTextBrowser
b.setText(str);
b.show();
int eHeight = b.contentsHeight();//correct height
int eWidth = b.contentsWidth();//correct width

ExplainBrowser b;//QTextBrowser
b.setText(str);
b.show();
int eHeight = b.contentsHeight();//correct height
int eWidth = b.contentsWidth();//correct width

To copy to clipboard, switch view to plain text mode 

Is there a way by which I can the correct contentsHeight() and contentsWidth() without actually showing the widget?

Thanks a lot.

By the way I am using Qt 3.3.6
