Seting the size of plot

[mikl]

I want to set the size of the plot to the same as the parent, how is that done? At the moment it is just a square in the corner.
I do not use the plugins, I havent got the working, I set the QWTPlot to a widget in the constructor.

QwtPlot *myPlot = new QwtPlot(QwtText("a Curves"),ui->widget);

Add a layout to the parent, that manages the size of the plot or implement its resizeEvent and do it manually.
This is a question for the Newbie forum and has nothing to do with Qwt.
