QTableView Stretch Headers but keep Interactive

[Adan895]

I am struggling triying to accomodate my QTableView to make it easy to the user.

This functions works as i really need:

ui->tableView->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);
The issue with this is that the headers are not user adjustable anymore, are completely frozzen.

I know we also have this function which allows the user to adjust the Headers, but after using it, the headers go back as if i had not used QHeaderView::Stretch before:

ui->tableView->horizontalHeader()->setSectionResizeMode(QHeaderView::Interactive);
I have really looked for this on many websites with no luck of finding a understandable answer for my level.

Thanks!

Hi Guys, after Struggling like 3 hours ive got it:

for(int c = 0;c<=4;c++){
        ui->tableView->horizontalHeader()->resizeSection(c, 150);
        }

        ui->tableView->horizontalHeader()->setStretchLastSection(true);

Set first the width of each column to match the QTableView size and then Stretch the last section, thanks a lot!

@Adan895 said in QTableView Stretch Headers but keep Interactive:
That is what https://doc.qt.io/qt-5/qheaderview.html#ResizeMode-enum says, Interactive (the user can resize) and Stretch (widths are set to fill view) are different from/incompatible with each other. So perhaps you will have to explain exactly what you mean by your "Stretch Headers but keep Interactive"?

Hi and welcome to devnet,

Are you triggering a resize to content size somehere in your code ?

@JonB Hi, i want to Stretch the headers to the size of the QTableview, but allow the user to adjust them if necessary.

@Adan895
So I think you should leave the mode on interactive and do a once-off stretch to get going?

setSectionResizeMode(QHeaderView::Interactive);
resizeSections(QHeaderView::Stretch);

@SGaist Hello, no, i am just stretching the headers to the QTableview size using QHeaderView::Stretch, but if i do that the user cannot resize the Headers if necessary manually.

@Adan895 So why don't you do what @JonB suggested? Maybe use ResizeToContents depending on what you really want.

@Adan895
Have you tried/noted the difference between setSectionResizeMode() and resizeSections(), as per the suggested code?

@JonB @Christian-Ehrlicher @SGaist Thanks, what you are suggesting sounds logical, i think it will work, once i arrive home later i will try it and i ll let you know.

@JonB @SGaist @Christian-Ehrlicher Hi guys, after triying using your advice, this is what happened, its not stretching.
