> We really don't have a toggle button? That is somewhat incredible.
BButton now has SetBehavior, which was added recently by Ingo as part of his
work on OpenJDK and SWT.
This works for a standard toggle button, but what I want here is a bit more
complex.
The "Original size" button works as before, as a standard button. If you
shift+click it, you enter the new mode where images are forced to original
size, instead of fitted to the window. To show this, the button switches to
toggle mode and stays pressed. Clicking the button again (with or without
shift) restores the normal behavior and depresses the button.
I also used this subclass to include the button behavior in the invoke
message. This allows the app to easily know that the button was clicked, locked
(shift+click), or unlocked. We could make this a shared class, if we want to
have the same behavior in other places, but I think it is quite specific to
this.
