[rkward-devel] some separate queries related to the plot history feature

[Thomas Friedrichsmeier]

Hi,

I've just started playing with the new history, so no feedback on that, yet. 
But some answers to these questions:

Looks fine to me.

I've run into problems with KMessageBox layout, before. Apparently a problem 
in kdelibs.

I have not stumbled across the affected message boxes in the plot history, yet. 
What do I need to do to see them?

Won't the "regular" approach work? I.e. replace with a wrapper, which calls 
the "real" dev.copy()/dev.set(). Since the "real" dev.set() will not call the 
wrapper, no recursion.

In case you want only the internal call, without the wrapper, call the "real" 
funtion directly.

In theory, yes, but I'd like to keep this somewhat lean. What do you have in 
mind? Separate icons for warnings, errors, information screens? That should be 
doable, but I don't think I'll get around to do it for this release.

I suggest you create one or two rkh files detailing the graphics device, plot 
history, and associated settings. Place this in rkward/pages. You may want to 
start linking it to the few existing pages in that directory, where 
appropriate. I'll look into adding a direct link to this page(s) in the Help-
menu of the graphics window, later.

Regards
Thomas
