[Solved]Get QModelindex
-
I got a treeview and a QFileSystemModel.
Yes it,s a simpel file explorer.And I want to show all data about the file like size type etc.etc
But I also want to show the file and its data in another Textbrowser so when I click on the filename in the Treeview its OK but when I click on other columns in the same row it's not possible to show the file.
I want to show the file also if I clic on the second column or third or etc etc.
Here is the code to get the file.@void Info::on_fileListTree_doubleClicked(QModelIndex index)
{
openfile(filemodel->fileName(index));
}
@I know that I need to change the index to the first column in the row but how?
And another question.
How could i get the same event as if i Click on the Row when I change row with the arrows on my keyboard.

First of all, I think you should at least make sure that you have the right selection mode enabled. You should use row-type selection.
Then, if you want to respond to a (double) click on a cell in a column other than column 0 as if it were in column 0, you could do something like this:
@
//untested code
void Info::on_fileListTree_doubleClicked(QModelIndex index)
{
if (index.column() > 0) {
//get index for column 0 in the same row
index = index.model().index(index.row(), 0, index.parent());
}
openfile(filemodel->fileName(index));
}

Yes that's exctly what I wanted and I got the selection mode sat to rowselect.
Thanks

By the way, I think the code becomes easier to read if you rename the index variable to something else. For times index in one line of code is a bit confusing, perhaps ;-)

Thanks.
Do you have an answer to my other question also.bq. How could i get the same event as if i Click on the Row when I change row with the arrows on my keyboard.
I miss the selection/row change or something in the slots
-
Did you try to connect to the itemActivated() signal?
-
Nope didn't find it in the treeview doc:
-
Get the [[Doc:QItemSelectionModel]] with selectionModel(), then connect to one or more of the signals currentChanged, selectionChanged or currentRowChanged.

Ok thanks I try this a little later.
