QTableWidget row insertion and set width of each column?

[darpan]

Hi,
I read the following functions but can't get how to set width of each column in QTreeWidget through QT Designer and through coding.

to access headers:
QTableView::horizontalHeader()
QTableView::verticalHeader()

to resize:
QHeaderView::resizeSection()
QHeaderView::setStretchLastSection()
QHeaderView::setResizeMode()
...

Please give some code example to set the width of QTreeWidget Column.

Thanks and Regards

I thought it was QTableWidget..

#include <QHeaderView>
QTreeWidget* treeWidget = ...;
treeWidget->header()->resizeSection(0, 20); // column 0, width 20
 
QTableWidget* tableWidget = ...;
tableWidget->horizontalHeader()->resizeSection(1, 50); // column 1, width 50
tableWidget->verticalHeader()->resizeSection(2, 15); // row 2, height 15

#include <QHeaderView>
QTreeWidget* treeWidget = ...;
treeWidget->header()->resizeSection(0, 20); // column 0, width 20

QTableWidget* tableWidget = ...;
tableWidget->horizontalHeader()->resizeSection(1, 50); // column 1, width 50
tableWidget->verticalHeader()->resizeSection(2, 15); // row 2, height 15

To copy to clipboard, switch view to plain text mode

Hi,
First of all sorry , you are right, it was QTableWidget. I had to set width of Each column of QTable Widget.
I also have requirement to delete all rows created through following lines:-
row = tableWidget->rowCount(); // current row count
tableWidget->setRowCount(row+1); // add one row
I am able to clear the whole QTableWidget but how i can delete all the rows created through setRowCount(row+1).


Thanks and Regards

You can always use QTableView::setColumnWidth() and call this both when your widget class is initialized and/or after your data loads.

For removing the rows, tableWidget->removeRow(row+1) ??
