WM.CHWIN - Vector $40
To move a window or change its size.
| Call Parameters | Return Parameters | ||
|---|---|---|---|
| D1 | x,y pointer move | ||
| D4 | 0 or pt..wsiz | ||
| A0 | channel ID | ||
| A4 | pointer to working definition | A4 | preserved |
Errors
| ORNG | Out of range |
Notes
- No other registers are used.
- For a move, WM.CHWIN just moves the window and sets D4 to zero.
- For a change size, WM.CHWIN sets the change in size in D1 and sets D4 to pt..wsiz (the window size event number - 6).
- The change in size is measured as Xnew - Xold, Ynew - Yold. Thus a move downwards and to the right gives positive values for both x and y.
- If the call to WM.CHWIN is incorporated in an action routine a move will not cause an exit from reading the pointer though a change size will.
