no horizontal scroll bar in QTableWidget

[moskk]

use

setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);

setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);

To copy to clipboard, switch view to plain text mode 

its not working. Qt::ScrollBarAsNeeded is a default value that used in designer. i tried to set it manualy, thats what i got:no_effect.png

I think this is because you have only one column (at least it seems so from the picture) and the column (not its contents) is visible so scrolling is not needed.

thats right. i have added second column and scroll was appeared. thank you very much!
but what is the reason of that behavior? am i have to add a fictive column to see the scroll?

try this: change the scrolling mode to ScrollPerPixel and set a minimum width for the QTableWidget's horizontal header, for example

tb.setHorizontalScrollMode(QAbstractItemView::ScrollPerPixel);
tb.horizontalHeader()->setMinimumWidth(minwidth);

tb.setHorizontalScrollMode(QAbstractItemView::ScrollPerPixel);
tb.horizontalHeader()->setMinimumWidth(minwidth);

To copy to clipboard, switch view to plain text mode 

here tb is QTableWidget.
