Qtablewidget is easy to use because there is no parent node relationship

Although it is relatively simple to use, it is necessary to go over it in person. You can take a study note and record it here.

# Include "tablewidgetxxx. H "# include <qtgui/qapplication> # include <qtgui/qtablewidget> typedef struct {char * country; double GDP, population;} gdp_facts; gdp_facts [] = {"United States", 14.6, 2.7 },{ "PRC China", 6.1, 13.0 },{ "Japan", 5.4, 1.3 }, {"Germany", 3.3, 0.8 },{ "United Kingdom", 2.3, 0.6 }}; int main (INT argc, char * argv []) {qapplication app (argc, argv); const int rows = 5, Colum NS = 4; // instantiate the table and specify the number of rows and columns qtablewidget widget (rows, columns); // set the table header qstringlist; list <"country" <"Grand GDP" <"Population" <"GDP per person"; widget. sethorizontalheaderlabels (list); For (int row = 0; row <rows; row ++) {// each items [J] represents a cell, make up a row of qtablewidgetitem * items [columns]; // set the cell style of each row for (Int J = 0; j <columns; j ++) {items [J] = new qtablewidgetitem (); // create a qtablewidget The item object indicates a cell data item in the table items [J]-> settextalignment (QT: alignhcenter); qfont font; font. setpointsize (16); items [J]-> setfont (font);} // set the cell content of each row gdp_facts * P = & gdp_facts [row]; // assign a struct pointer to point to the predefined fixed content items [0]-> setdata (QT: displayrole, p-> country ); // The constructed qvariant object stores a qstring value items [1]-> setdata (QT: displayrole, p-> GDP ); // The constructed qvariant object stores values of the double type items [2]-> setdata (QT: displayrole, p-> Po Pulation); items [3]-> setdata (QT: displayrole, p-> GDP/p-> population ); // set for (Int J = 0; j <columns; j ++) widgets one by one for cells in the table. setitem (row, J, items [J]); // call setitem () to add them to the internal model of qtablewidget.} // Set the table header sorting widget. setsortingenabled (true); widget.
