Whats the best solution?
-
I'm looking at some old code which tests for a single character in a QString, currently there are a lot if else tests with a single line in the body of the if:
if ( strSymbol== "~" ) { ui->lnedField->setText(ui->text() + "~"); } else if ( strSymbol == "!") { ui->lnedField->setText(ui->text() + "!"); } ....There is a total of about 40 if else's, is it more efficient to do this or to create a single array (string) of all characters to test then use:
QString strChList = "~!@#$%^& .... if ( strChList.indexOf(strTest) != -1 ) { QString strCurrent(ui->lnedField->text()); strCurrent.append(strTest); ui->lnedField->setText(strCurrent); }Or is there another more optimal solution?
Kind Regards,

@jsulm, Thank you
On looking into this a it further its not quite as straight forward as I first thought....because the destination is a QLineEdit, we first have to get the content of the QLineEdit, unfortunately QLineEdit has no append function.
