QML Tableview horizontal scrollbar - c++

Question

I am using TableView QML component, where each column width is set to the table total width divided by number of columns. This introduces some fraction parts and in result, a horizontal scrollbar is almost always visible in the bottom.
But I don't want to disable scrollbar as I have ability of changing column width and because of that scrollbar may be needed. So my problem is about initial showing of this TableView component. I want to get rid of that scrollbar when component is shown first time, but don't disable it for future usage.
I am new to QML and don't know all aspects of it, but solution that came to me is to set width of each column as I do, then for the last one get sum of all previous columns and set it's width to parent.width - that sum. Can you please help me to understand how can I implement this using QML?

Answer 1

columnWidthProvider is calculated once at adding column. I cant reproduce your bug with this. contentWidth become same as width
TableView {
id: table
anchors.fill: parent
columnWidthProvider: function (column) {
console.log(parent.width , columns, parent.width / columns)
// wdth is 0 here
return parent.width / columns
}
ScrollBar.horizontal: ScrollBar {
policy: ScrollBar.AsNeeded
}
//....
}
But i had same issue in another view. Solution was:
Flickable {
id:view
ScrollBar.horizontal: ScrollBar {
policy: (view.width - view.contentWidth < -3) ?
ScrollBar.AlwaysOff : ScrollBar.AsNeeded}
}
}
