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

[aftalib]

@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 ?

[Christian Ehrlicher]

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..

[aftalib]

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

[aftalib]

here is what i did in order to set the size of my tableviews :

where nbOfAnt/2 is the number of elements that are going to be in my table view
