how to set columnWidth correctly without having to use StretchMethods on a QTableView

aftalib

Hello i'm currently working on an interface with QTableViews in it and i'm having a hard time to deal with the columns. the thing is, i would like the cells to be the same size and to fill the whole Table. i cannot use SetStretchLastSection because the last cell will be uneven when i stretch my table view, and if i set my my QHeaderView to Stretch, the datas will be unreadable when i shrink my table view because there won't be any scroll bar displaying. in summary, how can i get my cells to be the same size without having the last one uneven or having to use QHeaderView::Stretch ?

aftalib

in other words (i am realizing i may not be as clear as i'm thinking) i would like my tableview to be entirely filled with my cells without having to use SetStretchLastSection(true);

Retrieve the width of the view and resize your sections to fill the whole view.

@Christian-Ehrlicher i thought about that but the witdh of my view is interactive. if i stretch it during the program it wont be fitting my cells anymore

Christian Ehrlicher

@aftalib Then you have to adjust your others accordingly after the resize.

aftalib

my others cells ?
i'm sorry i'm kind of a beginner i don't know how can i get my cells to resize along with my TableView

aftalib

so i went through a lot of documentation this morning and apparently there is no way/or existing function allowing to do this, apart from SetStretchLastSection(true). do you think there is a way to set the size of the last section in an absolute way ?

What's wrong with QHeaderView::resizeSection()?

aftalib

@Christian-Ehrlicher i tried it but SetStretchLastSection overrides resizeSection() : no matter if i put interactive, stretch or fixed, the last section is still wider than the other ones when i stretch it .

Christian Ehrlicher

Then don't use setStretchLastSection

aftalib

@Christian-Ehrlicher but if i do so my cells wont fill my QTableView

That's why I said 'Then you have to adjust your others accordingly after the resize.'

aftalib

@Christian-Ehrlicher yes that's what i want to do but i dont really know how to do this with the available functions

What are you missing? Getting the size of the view? How you resize a section was already answered:

aftalib

here's what happens when i set resizeSection() to interactive :

i have worse or even results with Stretch or Fixed.

to get the size of the view i do : QRect rect2 = ui->tableView->frameGeometry();

is this correct ?

thank you for taking the time to answer me

aftalib

my solution was to set the maximum width of each of my tableviews by the number of the future columns plus the vertical header width, the problem is when i stretch the window the last tableview is going away on the right as you can see here :

and i have no explanation for this to happen. each of these tableviews have the exact same settings

aftalib

@aftalib if anyone knows where the issue from my previous screen comes from i'd be very happy to know, this is the only thing getting in my way..

hello, posting as a last hope..

n-2204

you can make fixed size , setcolumn size
ui.tableView_1->setColumnWidth(4, 130);
ui.tableView_1->setColumnWidth(3, 110);
ui.tableView_1->setColumnWidth(2, 120);
ui.tableView_1->setColumnWidth(1, 120);
ui.tableView_1->setColumnWidth(0, 120);
Are you using layout for tables in mainwindow?

aftalib

@n-2204 yes i am using layouts which i why i am afraid this wont work
