Hi Everyone,
In the ROOT shell when I do
if(canv)canv->Close();
where “canv” is my TCanvas. It works perfectly, but it doesn’t seem to close my canvas within a program ! How can I properly close or delete a canvas after using it ? Within my code I will need to open and close several canvases.
Thanks
if (canv) {
canv->Close();
gSystem->ProcessEvents();
}
Thanks for your reply. I would also like to know, how can I check if the canvas did close ? Something like another if(canv)std::cout<<"Didn't close\n";
is it possible ?
Yes, but then you have do do this:
if (canv) {
canv->Close();
gSystem->ProcessEvents();
delete canv;
canv = 0;
}
Cheers,Bertrand.
Thanks very much Bertrand, it works like a charm.
