The following program tries to display 2 WText widgets, one at the top of the
browser window, one at the bottom. I use a WVBoxLayout and addStretch to try and
achieve this.
The intended result is that "top_line" is displayed at the top of the browser
window, and "bottom_line" is displayed at the bottom.
The actual result is that "top_line is displayed at the top of the browser
window, and bottom line is displayed immediately below "top_line".
Is there a way to place a stretchable area between 2 widgets arranged
vertically?
Using Wt 3.1.9 and Firefox 4.0.1
