How to get the QTableWidget Scrollbar Thickness?

[grantbj74]

Hi,

I am trying to get a column to expand when the dialog resizes. Currently the table and column resizes. But I was wondering if there is a better way to do it. I don't want to have to use the horizontal scrollbar.

At the moment I don't know a way to collect the scrollbar thickness. I just use 19. I believe I need to use something like: QStyle::PM_ScrollBarExtent

#define PHONEBOOK_DATA_COL            3
 
#define PHONEBOOK_INDEX_WIDTH         55
#define PHONEBOOK_NORMAL_HOURS_WIDTH  85
#define PHONEBOOK_AFTER_HOURS_WIDTH   85
 
void PhoneBook::resizeEvent(QResizeEvent *)
{
    int colwidth = m_ui->tableWidget->width() - (PHONEBOOK_INDEX_WIDTH
                                               + PHONEBOOK_NORMAL_HOURS_WIDTH
                                               + PHONEBOOK_AFTER_HOURS_WIDTH
                                               + 19);
 
    m_ui->tableWidget->setColumnWidth(PHONEBOOK_DATA_COL, colwidth);
}

#define PHONEBOOK_DATA_COL            3

#define PHONEBOOK_INDEX_WIDTH         55
#define PHONEBOOK_NORMAL_HOURS_WIDTH  85
#define PHONEBOOK_AFTER_HOURS_WIDTH   85

void PhoneBook::resizeEvent(QResizeEvent *)
{
    int colwidth = m_ui->tableWidget->width() - (PHONEBOOK_INDEX_WIDTH
                                               + PHONEBOOK_NORMAL_HOURS_WIDTH
                                               + PHONEBOOK_AFTER_HOURS_WIDTH
                                               + 19);

    m_ui->tableWidget->setColumnWidth(PHONEBOOK_DATA_COL, colwidth);
}

To copy to clipboard, switch view to plain text mode 

Thanks

I did something similar for a QTableView by grabbing the geometry of the actual scroll bar:

QRect g = m_ui->tableViewRight->horizontalScrollBar()->geometry();

QRect g = m_ui->tableViewRight->horizontalScrollBar()->geometry();

To copy to clipboard, switch view to plain text mode 

Then use QRect::height() or QRect::width().
It would be interesting to hear of a way to get the equivalent from the style system.

As for your desire to have one column soak up all the excess space by growing, you should look at QHeaderView::setResizeMode() and set a resize mode of QHeaderView::Stretch on that column.

Thanks! Yes thats a better way to do it.

Heres the code:

QHeaderView *header = m_ui->tableWidget->horizontalHeader();
 
header->setResizeMode( PHONEBOOK_DATA_COL, QHeaderView::Stretch);

QHeaderView *header = m_ui->tableWidget->horizontalHeader();

header->setResizeMode( PHONEBOOK_DATA_COL, QHeaderView::Stretch);
