[dabo-users] Tip: Justified-alignment of 2 controls in a horizontal dSizer

Over the years, I've had occasional need for laying out a control left-aligned, and

another control right-aligned, in the same horizontal sizer. I know there are lots of

ways to do this but I finally figured out how to do it succinctly with a normal dSizer:

{{{

vs = self.Sizer ## vertical sizer in the form, panel, or whatever

left_control = dabo.ui.dCheckBox(self, Caption="left-aligned")

right_control = dabo.ui.dButton(self, Caption="right-aligned")

hs = dabo.ui.dSizer("h")

hs.append(left_control)

hs.appendSpacer(0, 1) ## proportion=1

hs.append(right_control)

self.Sizer.append(hs, "expand")

}}}

Simply append a horizontal spacer and set its proportion to 1 to tell it to take all

remaining available space. I guess I'd missed that spacers could have proportion set.
