// The purpose of the QT_NO_TOOLTIP and QT_NO_WHATSTHIS ifdefs is because
// this file is also used in Konqueror/Embedded. One of the aims of
// Konqueror/Embedded is to be a small as possible to fit on embedded
// devices. For this it's also useful to strip out unneeded features of
// Qt, like for example QToolTip or QWhatsThis. The availability (or the
// lack thereof) can be determined using these preprocessor defines.
// The same applies to the QT_NO_ACCEL ifdef below. I hope it doesn't make
// too much trouble... (Simon)
