Hi,
Has anyone tried to use the Capsule-Style Toolbar Controls in an app
so that it looks and behaves like Mail or Preview? When I add them
to my toolbar it looks like Mail. But if I compare them side by side
the ones in Mail and Preview there is a 2 pixel difference of the
baseline. And I think it looks better in Mail/Preview. When I add a
multi-segment control I only have one Label (not two or more). In
Mail and Preview it looks like there are as many labels as segments.
You can "fake" this by adding blanks. But there is one more point:
In Mail and Preview the size of the control is adjusted (I think
depending on the size of the label(s)). Well, in the nib files from
Mail and Preview there are no toolbars, so Apple builds them via
code. So the question is: If I code them as well, is it possible to
do the same that Apple does in Mail and Preview via NSSegmentedCell
or is this all done by hand?
With best wishes, Stefan
Hi Stefan,
As of Leopard, this is all possible using standard AppKit controls,
which Mail and Preview both use.
Regarding the two pixel difference in the baseline, this may be
because the segmented control is too short and so is clipped. Try
using sizeToFit. You may also be referring to different window
metrics; try giving the window a unified title/toolbar to see if that
gives the appearance you expect. It shouldn't affect the appearance
much, but it does subtly change the toolbar positioning. If these
don't fix your issue, maybe you can provide a screenshot so I
understand what you mean.
To have multiple labels in a single toolbar item, make an
NSToolbarItemGroup, and give it subitems. If you set a view (but not
a label) on the Group, the labels of the subitems will be arranged
under the view. If the view is a segmented control, the labels will
be aligned with corresponding segments, assuming there's the same
number of both. This is what Mail and Preview do.
I hope that's clear,
-Peter
