Clear QCPItemText in QCustomPlot -
i can't clear items in qcustomplot
. method qcustomplot::itemcount()
returns 0.
qcustomplot *plot = new qcustomplot(this); qdebug() << plot->itemcount(); // returns 0 qcpitemtext *textlabel = new qcpitemtext(plot); qdebug() << plot->itemcount(); // returns 0
maybe qcpitemtext
not considered item, how clear qcpitemtext
then? or reset qcustomplot
?
use after allocate textlabel :
plot->additem(textlabel);
from documentation :
bool qcustomplot::additem ( qcpabstractitem * item)
adds specified item plot. qcustomplot takes ownership of item.
returns true on success, i.e. when item wasn't in plot , parent plot of item qcustomplot.
