Maybe a bug in QwtLegendItem::setIdentifierWidth(int) ?

[yannwilfried]

Hi,

i overloaded the method QwtPlotItem::updateLegend() to change the line width of my legend. The code is really simple and looks like:

QwtLegendItem *legendItem = qobject_cast<QwtLegendItem*>(legend->find(this));
if (legendItem) {
	//Set the width for the legend identifier to 24 pixels. Default is 8 pixels
	legendItem->setIdentifierWidth(24);
}

QwtLegendItem *legendItem = qobject_cast<QwtLegendItem*>(legend->find(this));
if (legendItem) {
	//Set the width for the legend identifier to 24 pixels. Default is 8 pixels
	legendItem->setIdentifierWidth(24);
}

To copy to clipboard, switch view to plain text mode 

I'm using Qt 4.7.2 with Qwt 5.2.1. MS Visual Studio always output the following error: error C2039: 'setIdentifierWidth' : is not a member of 'QwtLegendItem'

Am i doing something wrong or is it the reason why this method was replaced by void QwtLegendItem::setIdentifierSize(const QSize &size) in Qwt 6.x?

Thx,
Yann

It's not a bug.
Many APIs have changed in Qwt6 mainly because of dropping support for Qt3.
Just use new one and pass required size to it.
