Hi all,
SMSQ/E 3.16 is out.
It contains Marcel's bug fix for the AURORA COLOUR_NATIVE command.
There is also a new window move mode : move with transparency.
(This is an extract of the display_txt file in the extras_new directory:)
a - New move mode
------------------
The WM_MOVEMODE keyword has been extended to accept a new move mode:
WM_MOVEMODE 3 : the "full window with transparency" move
The window to be moved is made "transparent" : one can "see through" it.
This is done via "alpha blending". Alpha blending requires A LOT of
computing power. So, even if your machine can theoretically handle
this type of move, in practice it might not be feasible. I don't
believe, for example, that the QXL can handle it
For Q40/Q60 users, switching on the Cache is advisable...
This type of move is only implemented for display modes where alpha
blending actually makes sense, i.e. modes 16, 32 and 33. In other
display modes, such as the QL screen modes, or Atari mono modes, this
will be redirected to move mode 2.
Please note that you cannot use this move mode with anything but the
mouse - the keyboard (cursor keys) will not work.
b - Configuring/setting the move mode
-------------------------------------
The move modes are configured on a system-wide basis - you cannot have
onejob moving in mode 0 and the other in mode 1.
Thus, all jobs are affected by the move mode, even those written a
long time ago (unless, such as Qlib, the job doesn't use the WMAN move
routine).
The move mode can be changed in two ways:
1 - Configure SMSQ/E (WMAN) to a mode of your liking.
2 - Use the new WM_MOVEMODE keyword
This takes one parameter, an integer from 0 to 3:
WM_MOVEMODE 0 : the old way
WM_MOVEMODE 1 : the "outline" move
WM_MOVEMODE 2 : the "full window" move
WM_MOVEMODE 3 : the "full window with transparency" move
c - Configuring/setting the degree of transparency : WM_MOVEALPHA
------------------------------------------------------------------
You can set how transparent the window is supposed to be when being
moved, from nearly totally transparent to totally opaque. This is done
by setting the "alpha value", from 1 (nearly transparent) to 255
(totally opaque).
The alpha value is configured on a system-wide basis - you cannot have
one job moving with an alpha value of 100 and the other with 200.
Thus, all jobs are affected by this, even those written a long time
ago (unless, such as Qlib, the job doesn't use the WMAN move routine).
The alpha value can be changed in two ways:
1 - Configure SMSQ/E (WMAN) to a value of your liking.
2 - Use the new WM_MOVEALPHA keyword
WM_MOVEALPHA : this new keyword defines the amount of transparency the
window should have when moved about, from 1 (nearly transparent) to
255 (totally opaque).
Please note that
1) no check is made on the value passed to this keyword, but only the
lower byte is used.
2) a value of 255 is actually equivalent to move mode 2.
3) a value of 0 is allowed but, since this would make the window to be
moved totally transparent when it is moved (i.e. you would only ever
see the background) this is considered to be an error and a value of
255 will be used!
4) alpha blending requires a lot of computing power - it may be too slow
on your machine.

Nice new features!
Thanks to both of you Marcel and Wolfgang.
Now waiting for the QPC2 version.
