QToolTip::showText() for tree view

Ayush Gupta

cellRect

I tried with this code but still the text is showing in wrong position i.e in upper left corner of treeview

@Ayush-Gupta
Confirm (debug out) what the cellRect.topLeft() is returning for you?

Ayush Gupta

it shows
QPoint(0,0)

I would guess you then use an invalid index.
so please check your index before use with
index.isValid()

If you ask visualRect(index); for an invalid index, you get invalid rect and hence 0,0

So that is most likely what you are seeing.

Ayush Gupta

@mrjj I tried
index.isValid() it returns true for me.

Without your actual code and details
i cannot guess why it does not work for you
since it worked well in a sample.

I am using QSortFilterProxyModel also in my tree view with my custom model?
Would it be a cause ?

mrjj

Yes it might
and would explain the index be valid but has no
VisualRect we can count on.

I did not test it.

Please see if using
proxy->mapToSource(Index);

Does return a valid cell rect.
Look the returned QRect and see if it has valid values or not.

Ayush Gupta

doing that I got
ASSERT: "!"QSortFilterProxyModel: index from wrong model passed to mapToSource

mrjj

ok, please consult the docs and make sure you are using it as intended. :)
also check the index you use is valid etc.
