    When a label is assigned a contents, it will resize itself to fit

    However, in this case you have to make certain that the size is big enough
118
claus
parents: 113
diff changeset
    63
    to hold any changed logos later. (usually, you create the label first with
claus
parents: 113
diff changeset
    64
    the longest string first to have it compute its size, then set the fixSize 
claus
parents: 113

    attribute to avoid resizing later).
125
claus

diff changeset
    66
    Be careful when placing self-resizing labels into panels - by default,
claus
parents: 118
diff changeset
    67
    panels do not react on the size change - leading to ugly looking geometry.
claus
parents: 118
diff changeset
    68
    (but you can tell the panel to watch for changes with #elementsCHangeSize:)
