HorizontalHeaderView disappears if ProxyModel filtering doesnt return any value

Antonio Ortiz

Hi guys! I'm having an issue with QuickControls 2's TableView and HorizontalHeaderView. I sync both views in my code, but when I do filtering in my model (is a QSortFilterProxyModel) and it returns no value the header disappears.

This is the header's code (The HeaderDelegate is just a rectangle with fixed height 56 and a TextField inside of it):

 HorizontalHeaderView {
            id: header
            width: parent.width
            height: 48
            z: 2
            syncView: table

            delegate: HeaderDelegate{
                id: headerDelegate
                text: proxy.headerData(index, Qt.Horizontal, proxy.roleForName("headerName"))
                visible: true
                initialWidth: proxy.columnWidth(index)
}

This is the TableView's code:

TableView{
            id: table
            width: parent.width
            height: root.height - header.height - toolBar.height - 24
            flickableDirection: Flickable.HorizontalAndVerticalFlick
            model: proxy
            delegate: delegateChooser
            columnWidthProvider: function(column){
                return model.columnWidth(column);
            }
}

I'm using a custom fork of the proxy model found in this repo https://github.com/oKcerG/SortFilterProxyModel. We change it to support tables, but the filtering is the same.

Does anyone have a clue of what might be causing the header to disappear?
