3rd April 2009, 13:32
hi friends,
i am having a window with size (10,800,1010,40) .. its having a button (diagnosButton) ... a thread is running parallel which will receive communication from server and emit a signal newMessage (QString) ... in my mainwindow i get the signal of thread and called a slot ()
this is the slot

void TidBar::showToolTip(const QString &message)
QFont serifFont("Times", 12, QFont::Bold);
QPalette color;
int setval = 0;
color.setColor( QPalette::Inactive,QPalette::QPalette::ToolTipBase ,Qt::yellow);
//value = diagnosButton->mapToGlobal(diagnosButton->rect().topLeft());
value = diagnosButton->mapToGlobal(QPoint(0, 0));
qreal x = value.x();
qreal y = value.y();
QRect rectval = this->rect();
QPoint value2 (x + 70, y - 54);

QToolTip::showText(value2, message,this ,rectval );


i try to show a tooltip with the message from the thread signal newMessage(QString) .... i thought this tooltip will last for long until i move the cursor outside the window ...
but the tooltip disapper or hide afer few seconds .... i dont know where i mistaked .... please help

QToolTip has a default timeout of 10 seconds.
There are 2 ways you can display it longer -
1) Easy way : Use ur timer of say 5 sec, and show tooltip every 5 sec.. u can code logic when to quit

2) harder way : make your custom widget, override the tooltip event, and display your custom tooltip. You can close it on lost focus.

second way might be better..

umm..i'll say that instead of creating a custom widget and handling its tooltip event, you could go ahead and make a custom TOOLTIP itself..its just like creating a custom widget, just set the window flag to be Qt::tooltip..here is how u should go about it:

1. have the constructor take the heading and tooltip strings..put those in layouts..also include a close button so that it depends on user when to close the tooltip..or you could also have a timer started in there itself..as ur requirement may be

2. have a function in it like showTooltip(QWidget *parent,...), here parent would be the widget u need to show the tooltip on..u can use the code u wrote earlier to find the position where to show the tooltip on.

3. u can also add functions to show the tooltip on right/left of parent, thus giving you good control over everything.

And when u think about it, its very easy to make, about 2-3 hours work..other details are easy to figure out
