Yes, using one line in you app-defaults file for each resource. e.g Application*Foreground: green This will reset the default forground color to green. > For example I would like all my widgets to have the same color > background, or font,... which is not the one that is the > current default ; Right now I have to specify quite a lot > of things again and again... If you are using XtSetValues(), or an argument list at creation time then you are not setting new defaults, you are forcing the user to use the colors you have specified. > NOTE that I want to do this with a 'C' call or assignment > within application and not by specifying it at prompt level > or by using the ressource manager. Too bad. The Xt Intrinsics provide no way to do this, and if I have a my way they never will, this type of thing is handled just fine through the resource manager. > Also I having problem setting up the icon of my toplevel widget > (i.e I don't get an icon or icon name) after doing: > n=0; XtSetArg(arg[n], XtNiconName, "HELLO"); n += 1; > XtSetArg(arg[n], XtNiconPixmap,icon); n += 1; > XtSetArg(arg[n], XtNoverrideRedirect, True); n += 1; > XtSetValues(toplevel,arg,n); Override redirect windows are ignored by the window manager, therefore will not have an icon, are you sure you want an Override redirect window? I suspect that you don't. Chris D. Peterson MIT X Consortium Net: kit@expo.lcs.mit.edu Phone: (617) 253 - 9608 Address: MIT - Room NE43-213

The words "default ... that widgets will look for" and "not by using the resource manager" don't go together at all. One way or another, the resource database has to be involved. If you really want to make calls, you can use the Xrm routines in Xlib to modify the resource database before loading "non-defaults" and creating widgets. In R4, the routine XtAppSetFallbackResources might help you with whatever it is you're trying to do. > Also I having problem setting up the icon of my toplevel widget > XtSetArg(arg[n], XtNoverrideRedirect, True); n += 1; What window manager are you using? Most will ignore properties on override_redirect windows.

Well you can do it with C calls but probably not without using the resource manager. You need to put the resources into the resource database that the widget initialization code looks at. I don't have all of the particulars in front of me (and they just changed with R4), but if you'll dig around in the Xt sources it should be fairly easy (I did it in the R2 days). If R4 Xt has squirreled that database away to the point that it is inaccessible without changing the R4 Xt source, then I think that we have a bug in the R4 Xt Intrinsics. I think that the application ought to be able to attach information directly to the resource database as it sees fit. ----------------------------------------------------------------------- Benjamin Ellsworth | ben@cv.hp.com | INTERNET Hewlett-Packard Company | {backbone}!hplabs!hp-pcd!ben | UUCP 1000 N.E.
