How to resize qtablewidget rows?

[robgeek]

Good evening!

I have this table(picture 1) and i want to resize the row's height to show the data like the table(picture 2). And set the numbers in the middle, i'm talkin about the height.

I tried:

//Every number i try in place of 2 and 5 changes nothing!
val->setSizeHint(QSize(2, 5));

//Every number i try in place of 2 and 5 changes nothing!
val->setSizeHint(QSize(2, 5));

You are not seriously expecting an helpful answer, right?

Trying to increase your post count?

Sorry!

What did i do? I'm asking questions like i always do. Only thing different is the link, but i said i didn't use attachments because i'm having problems with it. If i did something wrong, i believe is more useful tell me what i did and i don't do anymore instead this answer.

I just want to set the height of the lines in my qtablewidget a little smaller, but "sizeHint" is not working!

What did i do?

You neglected to provide any useful information.

According to you you have an object "val" of an unknow type, which apparently has a setSizeHint() method that takes a QSize object.

Maybe setSizeHint() of that unknown type just stores the data, maybe it even ignores it.
Since the type is unknown to anyone but yourself, noone can possibly give any helpful advice.

Ok, now i see. Really sorry about that!

The object "val" is a QTableWidgetItem.

Bellow, the method:

void showHistTable(QTableWidget *table, Data historic) {
	for(int i = 0; i < historic.size; i++) {
		table->insertRow( i );
		for(int j = 0; j < historic.limit; j++) {
			QTableWidgetItem *val;
 
			// Put zero in front of the number if he is smaller than 10.
			if(historic.historic[i][j] < 10)
				val = new QTableWidgetItem( QString("0").append( QString::number( historic.historic[i][j] ) ) );
			else
				val = new QTableWidgetItem( QString::number( historic.historic[i][j] ) );
 
			val->setTextAlignment( Qt::AlignHCenter );
			val->setSizeHint(QSize(2, 5));// Nothing is changed if i set different vals for the arguments.
 
			// Set the row colors
			if(((i + 1) % 2) == 0)
				val->setBackgroundColor( QColor(149, 149, 149, 255) );
			else
				val->setBackgroundColor( QColor(186, 186, 186, 255) );
 
			table->setItem(i, j, val);
		}
	}
}

void showHistTable(QTableWidget *table, Data historic) {
	for(int i = 0; i < historic.size; i++) {
		table->insertRow( i );
		for(int j = 0; j < historic.limit; j++) {
			QTableWidgetItem *val;

			// Put zero in front of the number if he is smaller than 10.
			if(historic.historic[i][j] < 10)
				val = new QTableWidgetItem( QString("0").append( QString::number( historic.historic[i][j] ) ) );
			else
				val = new QTableWidgetItem( QString::number( historic.historic[i][j] ) );

			val->setTextAlignment( Qt::AlignHCenter );
			val->setSizeHint(QSize(2, 5));// Nothing is changed if i set different vals for the arguments.

			// Set the row colors
			if(((i + 1) % 2) == 0)
				val->setBackgroundColor( QColor(149, 149, 149, 255) );
			else
				val->setBackgroundColor( QColor(186, 186, 186, 255) );

			table->setItem(i, j, val);
		}
	}
}

I don't know if the numbers i'm using are too small(pixels), i tried bigger but nothing changed too.

If I remember correctly setSizeHint() of a QTableWidget item is ignored by default so it doesn't really matter what you set there.

By the way, 2 and 5 are really weird values to set a an item size. What would you expect to fit in that?

Nothing, i just wanted to see clearly if sizeHint was working.

So, is there another way to do what i want? How?

Use a custom delegate with reimplemented sizeHint.
