Qt true,false speed

[mero]

Hello,

Is there any difference in speed in writing code like Code1 and Code2 ?
I heard that Code2 is faster than Code1... ?

Code1:

if (strData.isEmpty() == true)
{
...

if (strData.isEmpty() == true)
{
...

To copy to clipboard, switch view to plain text mode 

Code2:

if (strData.isEmpty())
{
...

if (strData.isEmpty())
{
...

To copy to clipboard, switch view to plain text mode
