Message_ SetSlot
(Code &400C5)
| Message Block | |
|---|---|
| +20 | New slot size |
| +24 | Task handle of owner |
Use
This message is broadcast when the user tries to alter a task’s slot size by dragging the ‘memory bar’ in the Task Manager.
Notes
If a task allows for changing the memory workspace via the Task Manager, it should first check the task handle, acknowledge the message and then call Wimp_SlotSize.
This message is also sent by the Task Manager when a task is started. If this or any later message is not acknowledged, the task will get a green ‘memory bar’ in the Task Manager (instead of a red one) and will not receive this message again; it will not be possible for the user to alter the task’s slot size.
