This class implements labels, which are views to display a string or image. |
42 |
The Label will try to do its best to make its contents fit into the |
|
43 |
view. The contents can be a String, a collection of Strings (i.e. |
|
| 118 | 44 |
a StringCollection) or a Form/Image. |
| 63 | 45 |
|
46 |
The contents is drawn in fgColor/bgColor, which can be changed using: |
|
47 |
||
| 585 | 48 |
aLabel foregroundColor:aColor |
49 |
aLabel backgroundColor:aColor |
|
| 3 | 50 |
|
| 38 | 51 |
When a label is assigned a contents, it will resize itself to fit |
52 |
the required size. This resizing can be suppressed by setting the |
|
53 |
fixsize attribute to true using: |
|
| 63 | 54 |
|
| 585 | 55 |
aLabel sizeFixed:true |
| 3 | 56 |
|
| 38 | 57 |
This can be used, if resizing of the label is not wanted. |
| 63 | 58 |
However, in this case you have to make certain that the size is big enough |
| 118 | 59 |
to hold any changed logos later. (usually, you create the label first with |
60 |
the longest string first to have it compute its size, then set the fixSize |
|
61 |
attribute to avoid resizing later). |
|
| 125 | 62 |
Be careful when placing self-resizing labels into panels - by default, |
63 |
panels do not react on the size change - leading to ugly looking geometry. |
|
64 |
(but you can tell the panel to watch for changes with #elementsCHangeSize:) |
|
| 38 | 65 |
|
66 |
The placement of the contents within the label is controlled by |
|
| 63 | 67 |
the adjust attribute, it can be set with: |
68 |
||
| 585 | 69 |
aLabel adjust:how |
| 3 | 70 |
|
| 1946 | 71 |
where how is one of the symbols left, #right, #center, #centerEach, |
72 |
#centerLeft, #centerRight, #leftRight or #rightLeft |
|
73 |
(see the comment in Label>>adjust:). The default is #center. |
|
| 3 | 74 |
|
| 145 | 75 |
model-less operation (ok for static labels): |
| 118 | 76 |
if no model is set, the labels contents is set with: |
77 |
||
| 585 | 78 |
aLabel label:aStringOrImage |
| 118 | 79 |
|
80 |
and stays constant unless changed by new calls to #label:. |
|
81 |
||
82 |
||
| 145 | 83 |
model operation (ST-80 style): |
| 118 | 84 |
labels with a model, aspectMsg and labelMsg react to |
85 |
changes of the aspect, and send a labelMsg-message |
|
86 |
to the model in order to aquire a new labelString or image. |
|
87 |
The model should send 'self changed:aspectMsg' if it thinks the label |
|
88 |
should change and return a string or image from the labelMsg-message. |
|
89 |
||
| 585 | 90 |
label model:aModel. |
91 |
label aspect:aspectSymbol. |
|
92 |
label labelMessage:labelSymbol. |
|
| 118 | 93 |
|
| 585 | 94 |
model sends #changed:aspectSymbol |
95 |
---> label will redraw its label from value of model perform:labelSymbol |
|
| 118 | 96 |
|
97 |
Having a labelSymbol different from the aspectSymbol allows for two labels |
|
98 |
to react on the same aspect-change, but use different messages when asking |
|
99 |
the model for a new label contents. By default, the labelMsg is nil, |
|
100 |
so the label does NOT update its shown contents. |
|
101 |
The aspectMsg defaults to #value. |
|
102 |
||
| 125 | 103 |
|
| 145 | 104 |
|
105 |
channel operation (new ST/X style): |
|
106 |
||
107 |
the label will react on changes of the token found in the |
|
108 |
channels: foregroundChannel, backgroundChannel and labelChannel. |
|
109 |
These are valueHolders and can be shared between labels. |
