Plot Graph in tooltip

[abghosh]

Hi

I want to plot a graph of values read from a file in a tooltip of the cells which contains the index name for which data is to be plotted.
I am using QTableWidget. By using the following:

table->item(rowIndex, i)->setToolTip("Variable Name: " + table->item(rowIndex, i)->data(0)->toString());

table->item(rowIndex, i)->setToolTip("Variable Name: " + table->item(rowIndex, i)->data(0)->toString());

To copy to clipboard, switch view to plain text mode 

am able to get the variable name in the tootltip. But how can I insert a plot in the tooltip.
Is there any alternative way of doing so?
I have to use tablewidget.

Thanks for any help in advance.-

You will need to install event filter for your table widget and catch tooltip event and show your custom widget.

Hi Aamer4yu

Thanks.
But How to do that?

Read about QObject::installEventFilter. or QWidget::event.
Then check the event type. It must be QEvent::Tooltip. When that condition is met, show your custom widget and return true to indicate that the event was processed.
