c++ - QtGridLayout behaving like a QVBoxLayout? -

-

i'm having issues working qgridlayout. here's code , explanation comes after:

for(int =0; i<filecount; i++) {     int row = 0;     int col = 0;     qstring docname = filteredfiles.at(i).at(0);     qlabel* doctitle = new qlabel;     doctitle->settext(docname);     qlabel* docicon = new qlabel;     if(filteredfiles.at(i).at(2)== "word")     {         qpixmap icon("c:blah/blah/blah/wordicon.jpg");         docicon->setpixmap(icon);     }     else if(filteredfiles.at(i).at(2)== "excel")     {         qpixmap icon("c:/blah/blah/blah/excelicon.png");         docicon->setpixmap(icon);     }     else     {         qpixmap icon("c:/blah/blah/blah/ppicon.png");         docicon->setpixmap(icon);     }     gridcontainer->addwidget(docicon);     gridcontainer->addwidget(doctitle);     topgrid->addlayout(gridcontainer,row,col,1,1);     col++; } maincontainer->addlayout(topgrid);

the above code supposed make 2 qlabels, pixmap image 1 of labels, add pixmapped label , regular label qvboxlayout , add qvboxlayout qgridlayout. output grid supposed have on single row it's in column. can explain why happening?

enter image description here

i'm assuming gridcontainer qvboxlayout. you're adding widgets same layout. that's problem (as problem col variable being initialized inside loop, pointed out user2672165).

you should creating new gridcontainer object inside loop , adding topgrid layout, instead of adding same layout in topgrid layout on , on again.

int col = 0; int row = 0; for(int =0; i<filecount; i++) {     gridcontainer = new qvboxlayout; // create new layout     qstring docname = filteredfiles.at(i).at(0);     qlabel* doctitle = new qlabel;     doctitle->settext(docname);     qlabel* docicon = new qlabel;     if(filteredfiles.at(i).at(2)== "word")     {         qpixmap icon("c:blah/blah/blah/wordicon.jpg");         docicon->setpixmap(icon);     }     else if(filteredfiles.at(i).at(2)== "excel")     {         qpixmap icon("c:/blah/blah/blah/excelicon.png");         docicon->setpixmap(icon);     }     else     {         qpixmap icon("c:/blah/blah/blah/ppicon.png");         docicon->setpixmap(icon);     }     gridcontainer->addwidget(docicon);     gridcontainer->addwidget(doctitle);     topgrid->addlayout(gridcontainer,row,col,1,1);     col++; } maincontainer->addlayout(topgrid);

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
