Autoscale QTableWidget columns on resize

[genjix]

Say I add a bunch of columns to my TableWidget.

tw.horizontalHeader().resizeSection(0, 130)
tw.horizontalHeader().resizeSection(1, 150)
tw.horizontalHeader().resizeSection(2, 400)
tw.horizontalHeader().resizeSection(3, 100)
tw.horizontalHeader().resizeSection(4, 100)

tw.horizontalHeader().resizeSection(0, 130)
tw.horizontalHeader().resizeSection(1, 150)
tw.horizontalHeader().resizeSection(2, 400)
tw.horizontalHeader().resizeSection(3, 100)
tw.horizontalHeader().resizeSection(4, 100)

To copy to clipboard, switch view to plain text mode 

How can it resize (keeping proportions) so you never get the empty space at the end, nor horizontal scrollbars?

Thanks.

Have a look at QHeaderView::stretchLastSection(). That is maybe not exactly what you are looking for, but the easiest one. If not, you have to subclass your view (or install an event filter) and reimp QWidget::resizeEvent(). There you can set the width of your sections according the widget size.

OT: What font are you using in that application?

Thanks for your help. I will check those out.

That font is called 'Ubuntu' I can send you it if you find me on freenode #bitcoin-dev and message me (my nick is genjix)

Just dumping this code here for others who may search for this on Google:

class TransactionsTable(QTableWidget):
    def __init__(self):
        super(TransactionsTable, self).__init__()
        tw = self
        tw.setColumnCount(5)
        hedlabels = ('Status', 'Date', 'Transactions', 'Credits', 'Balance')
        self.hedprops = (130, 150, 400, 100, 100)
        tw.setHorizontalHeaderLabels(hedlabels)
        for i, sz in enumerate(self.hedprops):
            tw.horizontalHeader().resizeSection(i, sz)
        tw.setSelectionBehavior(tw.SelectRows)
        tw.setSelectionMode(tw.NoSelection)
