hi
#include <QToolTip>

QToolTip::showText( this->mapToGlobal( QPoint( 0, 0 ) ), "tooltip by code");

Connect a slot to the button::clicked signal, where you show your ToolTip-Text. The showText-function also contains a timeout-parameter

void QToolTip::showText(const QPoint &pos, const QString &text, QWidget *w, const QRect &rect, int msecDisplayTime)

If you set msecDisplayTime to e.g. 3000, it will stay visible for 3 seconds

@Pl45m4 @mrjj

  QRect rect;
  rect.setHeight(ui->pushbutton->height());
  rect.setWidth(ui->pushbutton->width());

   QToolTip::showText( this->mapToGlobal( QPoint( 0, 0 ) ), qTable,0,rect,3000);

What do you mean? You want to have a delay before showing the tool tip? If so then why not using QTimer?

@ManiRon

Check your parameters... you have no Text-parameter there...

QToolTip::showText( this->mapToGlobal( QPoint( 0, 0 ) ), "MY_TOOLTIP", qTable, rect,3000);

What is qTable in your case?

Hi
Works on linux and windows for me. (Qt 5.9)
it stays the time you tell it.
Do note however, you CANNOT click on the screen in the meantime. then it goes away at once.

@Pl45m4

qTable is my text

[ManiRon]

@mrjj no I am not clicking any where , still it is not showing for the specified time and also i will be showing some status in the tool tip which will be updated in a particular time period how can this be done ?

[ManiRon]

@mrjj it display the tool tip only for few milli seconds , is there something wrong i am doing ?

      QRect rect;
rect.setHeight(ui->pushbtn->height());
rect.setWidth(ui->pushbtn->width());

QToolTip::showText( this->mapToGlobal( QPoint( 0, 0 ) ), qTable,ui->pushbtn,rect,5000);

[ManiRon]

@jsulm No i want to show tool tip till some period of time

@Christian-Ehrlicher

       QRect rect;
rect.setHeight(ui->pushbtn->height());
rect.setWidth(ui->pushbtn->width());
this->setToolTipDuration(5000);
QToolTip::showText( this->mapToGlobal( QPoint( 0, 0 ) ), qTable,this,rect,5000);

tried something like this but no change

Hi
What Qt version are you using?
It works for me with Qt5.9/5.13 on Windows and Linux.
