QTableWidget headers not displaying
qt, qtablewidget
Solution
What's wrong?
The horizontal header needs the information of columns from `QTableWidget`. As a `QTableWidget` is instantiated, both column count and row count are null hence you got no headers show even if you called `setHorizontalHeaderLabels`.
Solution
Insert columns before you set the header:
ui->filesTable->insertColumn(0);
ui->filesTable->insertColumn(1);
QStringList labels;
labels << tr("Filename") << tr("Size");
ui->filesTable->setHorizontalHeaderLabels(labels);
Problem
I use the UI editor to create a QTableWidget. ``` MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); populateFilesTable(); connect(ui->browseButton, SIGNAL(clicked()), this, SLOT(selectDirectory())); connect(ui->searchButton, SIGNAL(clicked()), this, SLOT(findFiles())); } ``` This shows how the UI is setup and then I call the function `populateFilesTable()`. The function is as follows: ``` void MainWindow::populateFilesTable() { ui->filesTable->setSelectionBehavior(QAbstractItemView::SelectRows); QStringList labels; labels << tr("Filename") << tr("Size"); ui->filesTable->setHorizontalHeaderLabels(labels); ui->filesTable->horizontalHeader()->setResizeMode(0, QHeaderView::Stretch); ui->filesTable->verticalHeader()->hide(); ui->filesTable->setShowGrid(true); } ``` The headers aren't being displayed on the table, any ideas? Thanks.
