ROOT

Dear you,

I want to remove (or block) some items (such as the ‘SetEditable’) from the TCanvas’ contextmenu. Is there a way to do this?

Any help is appreciated.

Hi Handong,

Take a look at $ROOTSYS/tutorials/gui/customTH1Fmenu.C and at this simple example:

[code]void removeMenuEntry(const char *classname=“TCanvas”, const char *menuTitle=“SetEditable”)
{
TClassMenuItem *item;
TString itemTitle;
TClass *cl = gROOT->GetClass(“TCanvas”);

cl->MakeCustomMenuList();
TList *ml = cl->GetMenuList();
TIter next(ml);
while ((item =(TClassMenuItem *)next())) {
itemTitle = item->GetTitle();
if (itemTitle == menuTitle) {
delete item;
break;
}
}
}[/code]
Cheers, Bertrand.
