[SOLVED] how to get the QmodelIndex to a QString?
i am trying to get the current index of the listwidget but i am having problems. when i type
if (ui->userListWidget->currentIndex() == 0)@
i get an error: no match for 'operator==' in 'QAbstractItemView::currentIndex() const() == 0'. candidates are: bool QModelIndex::operator==(const QModelIndex&) const
when i type
QString temp = ui->userListWidget->currentIndex(); @
to get the string, i get the error: conversion from 'QModelIndex' to non-scalar type 'QString' requested.
how to get the QmodelIndex to a QString?
[edit, please add @ code tags to make your post easier to read, Eddy]
"The docs":http://developer.qt.nokia.com/doc/qt-4.8/qabstractitemview.html#currentIndex say that currentIndex returns a QModelIndex
So you could use it's "isValid member":http://developer.qt.nokia.com/doc/qt-4.8/qmodelindex.html#isValid
i am using...
@bool QModelIndex::isValid () const@
i am getting the error...
no matching function for call to 'QTextEdit::append(bool)'
i am trying to print the results to the textEdit
Please show us the relevant code. We don't have a cristal ball to see where that textEdit comes from ;)
ok Eddy. here is the code. thank you.
@ QModelIndex temp = ui->userListWidget->currentIndex();
I don't quiet understand what you want to achieve generally speaking. But if it is your goal to show the row number of the selected item you could use "currentRow":http://developer.qt.nokia.com/doc/qt-4.8/qlistwidget.html#currentRow-prop.
This gives you an int, which you can use in your textEdit.
Is that what you want?

What is "the string"? What do you want to append to your text edit? If you have a snippet of code that does not work, then please tell your fellow forumistas what you want to achieve. It's hard to guess this from broken code. I do have a guess and I'm pretty sure I now what you want to do, but I want to hear that from you.
lets say there are three items in the listwidget. when a user clicks the second item, i want to get the index from it. so the code would return number 2. the listwidget.currentindex does return it but in a modelindex. i need the number to be in a string so that i can work with it.
after reading Eddy's last post, i tested the currentRow and it is just what i was looking for. i marked this topic as solved.
