Adding tableview to scene, appearing small and with scroll bars

mrjj

Hi
Normally you assign some portion of the form to the table and if its bigger, it get scrollbars.

Is your goal to sum up all the header size so that it never will show scrollbars ?

Anyway, you could do like

.....
  indexPageTableView->resizeColumnsToContents();

   int width = (indexPageModel->columnCount() - 1) + indexPageTableView->verticalHeader()->width();    
        for (int column = 0; column < indexPageModel->columnCount(); column++)    
            width = width + indexPageTableView->columnWidth(column);    
  indexPageTableView->setMinimumWidth(width);

Hi @mrjj . I am finding it difficult in one more problem w.r.t to the current thread. with the solution that you have given above i am able to set geometry for the tableview so that scroll bars dont appear. this works in mac. but in windows the height and width doesnt fit the actual height and width and scroll bars are appearing.(so is the solution platform independent?) Can you pls help me here ?
Thanks for the help in advance.

Hi that is a bit odd as I did this on windows to test :)
It should be platform independent but as with all font stuff, there might be
difference.

So how many pixels are missing for it not to show scrollbars ?

like
indexPageTableView->setMinimumWidth(width+25);

or much , much more ?

Hi @mrjj . Thanks for the quick reply. around some 20 to 25 pixels is missing . we are doing resizeColumnsToContents() right. This should be considering the font sizes right ?

mrjj

@sachinrd
Hi
yes resizeColumnsToContents();
should calculate the needed space with the current font.
and we then add up the needed sizes and expand the view.

Do you use any stylesheet or anything that could make the calculation a bit off ?

I don't see it here from a fast test so i wonder what difference it.

@mrjj . yeah i am using this style:
indexPageTableView->setStyleSheet("QTableView::item{border: 2px solid black}");

@sachinrd

Hi @mrjj . i have removed the stylesheet changes. it still didnt work!

mrjj

@sachinrd
Hi
try setting
alt text

and see if then the table is not fully drawn.
I recall it will "reserve" some space for the scrollbars and hence the width of a scrollbar is missing in the calcualation.

@mrjj . Thanks a ton for your help. Its working perfectly.
