c++ - How to plot QAbstractItemModel using QCustomPlot -


is there direct way pass qabstractitemmodel qcustomplot? defining 2 qvector<double> xval , yval. when have plot, update these 2 vectors qabstractitemmodel launch plot function.

is there way qcustomplot can accept qabstractitemmodel?

afaik there not direct support qabstractitemmodel in qcustomplot. not sure how expect qcustomplot draw contents of qabstractitemmodel. know model simple model or complex 1 or hierarchical. that's 2 simple 2d plot qcustomplot. there seems way assign data of subclass of qabstractitemmodel qcustomplot , that's using qcpdatamap.

you should populate data of model in qcpdatamap , assign plot. that's :

qcpdatamap *data = new qcpdatamap();  for(int i=0; i<count; i++)     data->insertmulti(data->constend(), x[i], qcpdata(x[i], y[i]));  plot->graph()->setdata(data);

you can generate qcpdatamap in model using x , y values , assign it's pointer plot.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
