How to resize vertical header in QTableWidget

technovelist

I cannot figure out how to set the vertical header size for a QTableWidget. I have tried using resizeSection, but that doesn't seem to do anything other than wiping out the text I put in the vertical header. I have done a search here to no avail. Does anyone have an example of how to do this?

Thanks.

Is that what you want ?

tableView->verticalHeader()->setDefaultSectionSize(YourValue)

technovelist

I believe I have tried that to no avail, but I'll try it again and report back. Thanks.
No, that seems to have no effect, but I don't know what "tableView" signifies exactly.
Here's my code:

QTableWidget *InsurancePremiumTable;
...
ui->InsurancePremiumTable->setColumnCount(MaxYearsToModel);
m_InsurancePremiumRowNames.append("Ins. Premium");
ui->InsurancePremiumTable->setVerticalHeaderLabels(m_InsurancePremiumRowNames);
ui->InsurancePremiumTable->verticalHeader()->setDefaultSectionSize(500);
for (int row = 0; row < ui->InsurancePremiumTable->rowCount(); ++row)
for (int column = 0; column < ui->InsurancePremiumTable->columnCount(); ++column)
{
QTableWidgetItem *newItem = new QTableWidgetItem("");
ui->InsurancePremiumTable->setItem(row, column, newItem);
}

Can you see what I'm doing wrong? 500 isn't the actual size that I want, just a size that should show me that it's doing something.

try ui->InsurancePremiumTable->verticalHeader()- setSizeHint( QSize (500,500 ) );

technovelist

No, that doesn't compile.

Try this:

ui->InsurancePremiumTable->verticalHeader->setResizeMode(QHeaderView::Fixed);
ui->InsurancePremiumTable->verticalHeader->setDefaultSectionSize( 500 );

Or:

ui->InsurancePremiumTable->verticalHeader->setResizeMode(QHeaderView::Fixed);
ui->InsurancePremiumTable->verticalHeader()->resize( 500, 500 );

If it doesn't help try changing size for a single row:

ui->InsurancePremiumTable->setRowHeight( rowNumber, rowHeight );

technovelist

This doesn't compile:
ui->InsurancePremiumTable->verticalHeader()->setResizeMode(QHeaderView::Fixed);

I get this error:
mainwindow.cpp(736): error C2039: 'setResizeMode' : is not a member of 'QHeaderView'

and if I write it as you did,
ui->InsurancePremiumTable->verticalHeader->setResizeMode(QHeaderView::Fixed);

then I get a different error:
1>mainwindow.cpp(736): error C2227: left of '->setResizeMode' must point to class/struct/union/generic type

Hi,

You are missing a #include <QHeaderView> in mainwindow.cpp file

technovelist

Nope, that doesn't help; I get the same error:
1>mainwindow.cpp(745): error C2039: 'setResizeMode' : is not a member of 'QHeaderView'

Any other suggestions?

Because it's an obsolete function, see here for the replacement

technovelist

That compiles okay but doesn't do anything visible other than wiping out my label

Here's my code:

ui->InsurancePremiumTable->verticalHeader()->setSectionResizeMode(QHeaderView::Fixed);
ui->InsurancePremiumTable->verticalHeader()->resizeSection(0, 500);
m_InsurancePremiumRowNames.append("Ins.    Premium");
ui->InsurancePremiumTable->setVerticalHeaderLabels(m_InsurancePremiumRowNames);
for (int row = 0; row < ui->InsurancePremiumTable->rowCount(); ++row)
	for (int column = 0; column < ui->InsurancePremiumTable->columnCount(); ++column)
	{
		QTableWidgetItem *newItem = new QTableWidgetItem("");
		ui->InsurancePremiumTable->setItem(row, column, newItem);
	}

Your header width gets pretty big, isn't 500pixel a bit wide ?
