an instance of me is used to provide tooltips |
|
| 4313 | 50 |
sigh: Smalltalk was ahead of its time in the early 90's: |
51 |
initially called 'activeHelp', |
|
52 |
then renamed to 'flyByHelp' |
|
53 |
and is now commonly known as 'tooltip'. |
|
| 4055 | 54 |
|
55 |
I will watch the mouse movements via an event hook, and determine |
|
| 4313 | 56 |
where the mouse pointer is. |
57 |
Then ask the underlying view about its helpText |
|
58 |
and display it in a little floating popup view. |
|
59 |
||
60 |
The tool is installed via: |
|
61 |
FlyByHelp start |
|
62 |
and possibly deactivated/uninstalled via: |
|
63 |
FlyByHelp stop |
|
| 4055 | 64 |
|
| 4313 | 65 |
There can be only one FlyByHelp at any time - the start/stop methods assure that. |
| 4055 | 66 |
|
| 4313 | 67 |
Additional features: |
68 |
if you press CTRL, the helpKey which was responsible for the helptext |
|
69 |
is shown instead of the full text. This helps to find out which text to modify |
|
70 |
in case of typing errors or missing translations. |
|
71 |
||
72 |
if you press LEFTSHIFT+RIGHTSHIFT+CTRL (in that order), a menu developper menu appears, |
|
73 |
but only if Smalltalk is in the debeloper mode (i.e. not in end-user applications). |
