i want tooltip display for lineedit but display in other region and out of my widget !!!!

Try:
@1->setToolTip("sometext");@

instead of your line in "onbtnclick()"

i know but i want this instead of setToolTip ! please guide me with QToolTip::show static function

Blizzard

Okay sorry, I didn't understand your initial question. Just to clarify, you want to display a tooltip - and define its position. The first argument in showText() defines the point of interest, not the point of display, so i don't think you can achieve your goal using that function. Have you thought of creating a label widget to look just like a tooltip and using a hover event to trigger it?

Read the "QHoverEvent Doc":http://doc.qt.nokia.com/4.7-snapshot/qhoverevent.html and once you set up your hover signal, create a slot that shows your custom tooltip.

According to "QToolTip::showText":http://qt-project.org/doc/qt-4.8/qtooltip.html#showText docs, ...

bq. Shows text as a tool tip, with the global position pos as the point of interest

So you need to map widget coordinates to global : "QWidget::mapToGlobal":http://qt-project.org/doc/qt-4.8/qwidget.html#mapToGlobal
