c++ - Set Value to QComboBox from QStringList -


in qt c++ gui application have qdialog window, there have few line-edits , setting display texts function call , settext(). have stored values in qstringlist (the qstringlist populating via database query) , setting text follows--

void mydialog::setdatatoform(qstringlist sl) {         ui->namelineedit->settext(sl[0]);         ui->emaillineedit->settext(sl[1]); }

now, have qcombobox (gendercombobox). have set 3 items there - male, female, other (through qt creater layout editor). in qstringlist sl, value getting saved in sl[2].

how can set value of sl[2] qcombobox ???

you need set currentindex of qcombobox:

qstringlist genderlist; genderlist << "male" << female" << "other"; ui->gendercombobox->setcurrentindex(genderlist.indexof(sl[2]));

while works example, suggest having @ samples provided in qt documentation (books example, sql widget mapper example) use models automatically populate widget contents based on sql tables.

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.
