hi, all
My contribution for exporting data from TableView to CSV if it is ok and
useful:)
void ***::exportTableView(Wt::Ext::TableView *tv, bool includeHidden) {
Wt::WAbstractItemModel *model = tv->model();
int rows = model->rowCount();
int cols = model->columnCount();
string file_ = "/tmp/list" +
wApp->sessionId() +
servertime() +
".csv";
string _file = ReadConfig("RootDir") +
ReadConfig("AppDir") +
file_;
ofstream csv(_file.c_str());
// header
for(unsigned j = 0; j < cols; ++j) {
if(!includeHidden) {
if(tv->isColumnHidden(j)) {
if(j == cols-1) {
csv << "\n";
continue;
}
else
continue;
}
}
// export
WString str = Wt::asString(model->headerData(j));
if(j == cols-1)
csv << (str + "\n").toUTF8();
else
csv << (str + ",").toUTF8();
}
// data row
for(unsigned i = 0; i < rows; ++i) {
// data col
for(unsigned j = 0; j < cols; ++j) {
if(!includeHidden) {
if(tv->isColumnHidden(j)) {
if(j == cols-1) {
csv << "\n";
continue;
}
else
continue;
}
}
// export
WString str = Wt::asString(model->data(i, j));
if(j == cols-1)
csv << (str + "\n").toUTF8();
else
csv << (str + ",").toUTF8();
}
}
csv.close();
Wt::Ext::MessageBox::show("Ok",
"Download：" + WString(href(file_, "The CSV
list")),
WFlags<StandardButton>(Ok));
unlink(_file.c_str());
}
