IM-V (p 156) discusses the reservation and use of animating colors. The
section of interest reads [end of first paragraph under the "Animating
Colors" section]:
.... However, when you call PmForeColor the Palette Manager will
locate the reserved index [of the animating color] and configure
your window's port to draw with it. On multiple devices this will
likely be a different index for each device, but this process will
be invisible to your application.
I have created a window that has sixty-four (64) animating colors and
all of the colors animate perfectly when the window is on the main screen.
However, when this window is moved to another screen, the colors no longer
animate. The way I understand the section of IM-V quoted above is that
the Palette Manager will take care of animating the proper indices on every
device that the window spans (wishful thinking, I know). I can imagine
only one thing that may be non-standard: the window is not active when
the colors are being animated. (Again, it works fine on the main screen
and even in multiple inactive windows on the main screen; but move
the window to a second screen and the colors no longer animate).
What I would like to know is: How can I get colors to animate across
multiple devices? Do I need to bypass the Palette Manager and
ReserveEntries for the animating colors on each device? Do I need to
let the PaletteManager know (somehow) that the window is now spanning
multilpe devices?
If anyone has any experience animating colors across multiple devices,
please let me know what I might be doing wrong. If you have code that you
can share, please share it with me.
Thanks in advance,
