This class implements labels, which are views to display a string or image. |
51 |
The Label will try to do its best to make its contents fit into the |
|
52 |
view. The contents can be a String, a collection of Strings (i.e. |
|
| 118 | 53 |
a StringCollection) or a Form/Image. |
| 63 | 54 |
|
55 |
The contents is drawn in fgColor/bgColor, which can be changed using: |
|
56 |
||
| 585 | 57 |
aLabel foregroundColor:aColor |
58 |
aLabel backgroundColor:aColor |
|
| 3 | 59 |
|
| 38 | 60 |
When a label is assigned a contents, it will resize itself to fit |
61 |
the required size. This resizing can be suppressed by setting the |
|
62 |
fixsize attribute to true using: |
|
| 63 | 63 |
|
| 585 | 64 |
aLabel sizeFixed:true |
| 3 | 65 |
|
| 38 | 66 |
This can be used, if resizing of the label is not wanted. |
| 63 | 67 |
However, in this case you have to make certain that the size is big enough |
| 118 | 68 |
to hold any changed logos later. (usually, you create the label first with |
69 |
the longest string first to have it compute its size, then set the fixSize |
|
70 |
attribute to avoid resizing later). |
|
| 125 | 71 |
Be careful when placing self-resizing labels into panels - by default, |
72 |
panels do not react on the size change - leading to ugly looking geometry. |
|
73 |
(but you can tell the panel to watch for changes with #elementsCHangeSize:) |
|
| 38 | 74 |
|
75 |
The placement of the contents within the label is controlled by |
|
| 63 | 76 |
the adjust attribute, it can be set with: |
77 |
||
| 585 | 78 |
aLabel adjust:how |
| 3 | 79 |
|
| 1946 | 80 |
where how is one of the symbols left, #right, #center, #centerEach, |
81 |
#centerLeft, #centerRight, #leftRight or #rightLeft |
|
82 |
(see the comment in Label>>adjust:). The default is #center. |
|
| 3 | 83 |
|
| 145 | 84 |
model-less operation (ok for static labels): |
| 118 | 85 |
if no model is set, the labels contents is set with: |
86 |
||
| 585 | 87 |
aLabel label:aStringOrImage |
| 118 | 88 |
|
89 |
and stays constant unless changed by new calls to #label:. |
|
90 |
||
91 |
||
| 145 | 92 |
model operation (ST-80 style): |
| 118 | 93 |
labels with a model, aspectMsg and labelMsg react to |
94 |
changes of the aspect, and send a labelMsg-message |
|
| 5782 | 95 |
to the model in order to acquire a new labelString or image. |
| 118 | 96 |
The model should send 'self changed:aspectMsg' if it thinks the label |
97 |
should change and return a string or image from the labelMsg-message. |
|
98 |
||
| 585 | 99 |
label model:aModel. |
100 |
label aspect:aspectSymbol. |
|
101 |
label labelMessage:labelSymbol. |
|
| 118 | 102 |
|
| 585 | 103 |
model sends #changed:aspectSymbol |
104 |
---> label will redraw its label from value of model perform:labelSymbol |
|
| 118 | 105 |
|
106 |
Having a labelSymbol different from the aspectSymbol allows for two labels |
|
107 |
to react on the same aspect-change, but use different messages when asking |
|
108 |
the model for a new label contents. By default, the labelMsg is nil, |
|
109 |
so the label does NOT update its shown contents. |
|
110 |
The aspectMsg defaults to #value. |
|
111 |
||
| 125 | 112 |
|
| 145 | 113 |
|
114 |
channel operation (new ST/X style): |
|
115 |
||
116 |
the label will react on changes of the token found in the |
|
117 |
channels: foregroundChannel, backgroundChannel and labelChannel. |
|
118 |
These are valueHolders and can be shared between labels. |

Notice, that Buttons and others inherit from Label; |

therefore, the following geometry examples apply to all subclasses too. |
