this class implements a pop-up box to show an information message.
|
|
|
39 |
WarningBoxes are basically InfoBoxes with a different bitmap-image.
|
|
|
40 |
(also, they add a beep when popping up)
|
|
|
41 |
|
|
|
42 |
They are created with:
|
|
|
43 |
|
|
59
|
44 |
aBox := WarningBox title:'some title'.
|
|
38
|
45 |
|
|
|
46 |
and shown with:
|
|
|
47 |
|
|
59
|
48 |
aBox showAtPointer
|
|
38
|
49 |
|
|
|
50 |
The default box shows 'yes' in its button; this can be changed with:
|
|
|
51 |
|
|
59
|
52 |
aBox okText:'some string'.
|
|
38
|
53 |
|
|
79
|
54 |
Since showing warnings is a common action, a convenient method has been
|
|
|
55 |
added to Object; thus you can use:
|
|
|
56 |
|
|
|
57 |
self warn:'oops - headcrash'
|
|
|
58 |
|
|
|
59 |
everywhere in your code.
