ide_messageBox CODE [ARGUMENTS]
|
| 22 |
|
|
|
| 23 |
|
|
This is just like tk_messageBox, except that it does not return
|
| 24 |
|
|
a value. Instead, when the user clicks on a button closing the
|
| 25 |
|
|
message box, this invokes CODE, appending the selected value.
|
| 26 |
|
|
|
| 27 |
|
|
On Windows, this runs the MessageBox function in another
|
| 28 |
|
|
thread. This permits a program which handles IDE requests from
|
| 29 |
|
|
other programs to not return from the request until the
|
| 30 |
|
|
MessageBox completes. This is not possible without using
|
| 31 |
|
|
another thread, since the MessageBox function call will be
|
| 32 |
|
|
running its own event loop, and will be higher on the stack
|
| 33 |
|
|
than the IDE request.
|
| 34 |
|
|
|
| 35 |
|
|
On Unix tk_messageBox runs in the regular Tk event loop, so
|
| 36 |
|
|
another thread is not required.
