If you are using Eclipse's form toolkit infrastructure, you might run into an problem where you try to install a context menu but it does not appear. If you are using FormToolkit.adapt(Composite)
to adapt a custom composite to a form, you must install your menu after adapting it. Otherwise, your menu will be replaced by the parent's menu. This may seem to be reasonable behaviour -- except when the parent widget has no menu at all.

This "blog" is really just a scratchpad of mine. There is not much of general interest here. Most of the content is scribbled down "live" as I discover things I want to remember. I rarely go back to correct mistakes in older entries. You have been warned :)
