Controlling Sizing of Widgets with RowLayout
Another
useful setting of
RowLayout
is pack
.
pack controls the initial sizing of widgets placed
in the container. A setting of true
allows
RowLayout
to create widgets of different sizes,
depending on the widget type and the text setting of the widgets. The
effect is seen in Figure 9-4, where each widget has
a different size. The size of the Button
widgets
is controlled by the text each contains, hence the Cancel button is
larger than the OK button.
Your interface design may require that you force all widgets in a row to be the same size, no matter what their style or contents.
How do I do that?
As with the wrap
setting, you directly access the
pack
setting field by:
rl.pack = false;
Adding this line to RowLayoutExample
creates Figure 9-7 when executed.
Figure 9-7. RowLayout with pack = false
