LKBEN11207: Convert LPTSTR to QString with UNICODE defined


On Windows you often have LPTSTR string and you need to convert them




A LPTSTR depends on the UNICODE environment found on the Windows System. If UNICODE is defined an LPTSTR is the same as an LPWSTR.

In this case we are dealing with a wide string. Here an exaple how you can convert it to a QString.

    ui.setupUi(this); //setup some user interface

    LPTSTR testStr = L"and I am a LPTSTR defined in the Windows headers!";

    QString qtTestStr = "This is the pure QString... ";

    qtTestStr += QString::fromUtf16(testStr); //concatenate

    ui.plainTextEdit->setPlainText(qtTestStr); //set it as text to some UI widget
