c++ - Clear temporary list without clearing where I assign it to -


i have 'slate' current screen, in screen 'pages' hold 'items' 12 in size, because fit on screen, have tried check, once reaches 12 items, make new page, code listed below leaves no items in either page 1 or page 2

int pageitems = 0;     std::list<item*> templist; page* temp = new page;   (std::list<item*>::iterator iter = items.begin(); iter != items.end(); ++iter) {     templist.push_back((*iter));     if (pageitems >= 13) {         page_count++;         temp->items = templist;         pages.push_back(temp);         templist.clear();         temp->items.clear();         pageitems = 0;     }     pageitems++; }

page class holds std::list, should handle 12, , new page created next amount, if goes above 12, new class , slate class holds std::list std::list, item 1 easier create class, because didnt have pages, , feed 'items' 'pages' according how many given slate

i think problem:

    temp->items.clear();

you seem clear page after adding list of pages

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
