Deriving "leftover" space value

mzimmers

Hi all -

Consider this code snippet:

ColumnLayout {
    id: newZone

    // other stuff
    
    ListView {
        id: viewArea
        Layout.preferredHeight: // what do I put here?
        Layout.preferredWidth: newZone.width
        clip: true
        model: 100
        delegate: Text { text: model.index; font.pixelSize: 10 }
    }
}

Is there a way to automatically derive the available space for my ListView's height, or do I need to do the arithmetic of:

leftover = newZone.height - otherStuff.height

Thanks...

Layout.fillHeight: true uses all the remaining height.

@mzimmers is Layout.preferredHeight equal to 100 * 10(text numbers * font size)?
But normally there is some space among the rows of ListView.
It may not be a good idea to do
delegate: Text { }
I use
delegate: Rectangle { }

@JoeCFD I don't want to set the ListView height to its content height; that causes the problem I'm trying to solve. I want to set the ListView height to whatever is available.

Layout.fillHeight: true uses all the remaining height.

@GrecKo I knew that. Seriously, I did.

My app was misbehaving due to some conflicting settings, but once I emptied the trash, it worked just as you said.

Thanks...
