QTreeView inline edit alignment problem
-
PROBLEM
As shown in the screenshot, column "2018" is right aligned.
When editing an empty cell in this column, the inline edit shows as in the screenshot.
I think the inline edit should match the cell size properly.ENV

Which of the following are you asking about/not liking:- The line edit is not as wide as the
2018(or2017) column? - The line edit's content is left- not right-aligned?
- The line edit for the
2018column appears in the2017column (apparently)?

For column "2018",
- the width of the edit is not as wide as the column
- the offset of the edit is not as expected, it should on the cell in column "2018", but it's in column "2017" now
- The line edit's content is left- not right-aligned?

Well let's start with: I have never seen the edit widget appear anywhere else than in its own column, certainly not in another column. So I suggest you start by discovering why this is for you (e.g. try a minimal case in a fresh application).Look at your table view's
itemDelegate(). You can access the line edit in QAbstractItemDelegate::createEditor(), e.g. set it to align right or affect its width. You may have to derive your own class fromQStyledItemDelegateand set the table view to use that. - The line edit is not as wide as the

It's hard to write a simple demo to reproduce the problem.
But I find that the width of inline edit changes dynamically to fit text.@jronald
It should not be hard at all, just aQTableViewwith a 2 column model. If it is hard to reproduce then something is going on/others will not be able to repro. As I say, I have used it many times with no problems, and don't you think other people would report if every time they tried to edit from aQTableViewit went as badly wrong as this?Anyway, if it really does this (and I think you have something wrong in your code) I told you what you can do about it.
