The answer is no. 1) X always must always have a cursor. 2) The cursor's appearence depends on the window it is over. You can change the root window cursor with xsetroot, and if another window doesn't specify a cursor, it inherits the cursor from it's parent. If no parent all the way down to the root window has specified a cursor then that window gets the root window cursor. But if windows have specified cursors explicitly, there's nothing you can do about that. Mark. ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

I think that X fundamentally requires that you have exactly one cursor. You can however change the way it looks by changing the cursor font. You can write a cursor font which has an invisible cursor, so the user will not see anything. (I don't remember the syntax, but there several ways of changing cursor font). The only problem I see with that is that any application can change the cursor font, and some applications use their own font, so you can't guarantee that a cursor will never appear. However this will only happen when such an application has focus, so should not be a major problem. -- Andrew C Aitchison ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
Re: Can I hide the cursor?
If you use XFree 4.3 with libxcursor, you can create a completely transparent cursor theme. -- Matthew on Wed, Aug 06, 2003 at 02:21:35PM +0800, tom wrote: > I want to hide the cursor when I using touchscreen in XFree86 4.20,I found that this > quesstion have been discussed three times,but no answer.Then,does this means I can't > hide the cursor at all?Can "xsetroot" resolve this problem?I tried but faild.I just > can't change the cursor with it. > Any idea? > > Thank you. > > Roy > > > > > - > Do You Yahoo!? > ?? ??+??? ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

I want to hide the cursor when I using touchscreen in XFree86 4.20,I found that this quesstion have been discussed three times,but no answer.Then,does this means I can't hide the cursor at all?Can "xsetroot" resolve this problem?I tried but faild.I just can't change the cursor with it.

Might help, but applications can change themes as well as cursors. Actually, in practise it would probably be good enough. -- Andrew C Aitchison ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
