Is there going to be any support for this in R4 ? Right now, I am writing an imaging application where I need to repeatedly load color maps, depending upon how I wish to view my image. Right now, I have use Xlib functions like XInstallColormap and XSetWindowColormap to over-ride the window manager. I have been successful on the DEC window manager (thanks to the hints by Chris Peterson and his colleague), but the ardent window manager simply refuses to install the user color map. Support for Color manipulation at the widget level would make things lot easier for application programmers. harish pu. hi. harish@ecelet.ncsu.edu harish@ecebucolix.ncsu.edu

Support for Color manipulation at the widget level would make things lot easier for application programmers. You don't really describe what you want (and widget level support won't really solve problems with non-ICCCM window managers), but you can read through the just-released Xt revisions to see if what you need is there. If it isn't, you'll have to do a better job of saying what you want.

The proposed revisions to Xt for R4 do include additional support for colormap specification, in the nature of convenience functions that support the ICCCM-specified window properties. No additional support that would be contrary to the ICCCM is contemplated. There is currently no mechanism in the ICCC by which a client can call XInstallColormap and remain ICCCM-compliant.
