[Qt-qml] Text eliding

[mathias.malmqvist at nokia.com]

Hi Bo,

Maybe what you need is a variation (for single-line texts) of what I tried to ask for here
https://bugreports.qt.nokia.com/browse/QTBUG-16665

But at the time I couldn't come up with a concrete example so the suggestion was closed as incomplete. 
Perhaps you can add your use case to the above posting.


Cheers
Mathias

Subject: [Qt-qml] Text eliding

I'm trying to ellide a text item, but it's proving quite complicated.
I'm tempted to implement my own C++ based QML class that does this, but
it just seems silly.

The problem is that Text says it can only elide when you have set the
width, but I don't have that.

I have something like this:

Item {
   width: parent.width
   anchors.centerIn: parent
   Text {
     id: text1
     text: ...
     elide: Text.ElideRight
     horizontalAlignment: Text.AlignHCenter
     verticalAlignment: Text.AlignVCenter
     font.bold: true
   }
   Text {
     id: text2
     text: ....
   }
}

(most anchors and stuff like that has been omitted)

So I want text1 to elide on the right side, when the combined text of
the two doesn't fit in the row. What I actually have here is a max width
which is parent.width - text2.width. In HTML, it would look like this:
"<center><bold>text1</bold>text2</center>", except that text1 should be
elided.

It might be that there is a way to set something like this on the text2
width:

width: max(font.textWidth(text), parent.width - text2.width)

But I haven't been able to figure out how to do that.

Any good ideas?
