[rkward-devel] Failure to withdraw window

[Matthieu Stigler]

Hello

I'm facing some problem with the graphics in RKward. It arrives often 
that after some time the window doesn't appear. An error message is 
given in the terminal:

rkward: *** Embed 60817409 into 44054206. window=0
rkward: > before reparent: parent=0x57
rkward: > Loop 0: > reparent of 0x3a00001 into 0x2a036be successful

rkward:  failure to withdraw window

I can't reproduce this bug exactly at a given moment but encounter it 
nearly every day. Do you have an idea? Maybe is it a memory problem, 
because I deal with big computations. Should I send more informations 
about the session? You will find some at the bottom.

Maybe is it due to a bad compilation of Rkward 0.4.9. I have Ubuntu 7.10 
and was unable to use the debian package (still a kdelibs4c2a dependency 
problem, I have the 4: 3-5-8 version) and compiled it myself (so maybe 
badly).

Otherwise, I'm a little bit confused using Rkward when I try to stop a 
command. Take following example:
example<-function(x) {
x^2
If one runs this code and forgets the second bracket he won't be able to 
run an other command.

The user has the solution:
-just select a bracket and run it, which can give an error message
-go to the pending jobs interface, push "pause the execution"  or 
"cancel the operation" but after it the user won't be able to run a new 
command.

So my question is if it is possible to add a button next the run button 
to stop everything like in the Windows Rgui?

Something more... I have sometimes the problem that there are many "run" 
buttons. See the picture (if you can receive it).


Finally I want to thank you much for what you do for Rkward. It is 
really nice and every time I come back on the windows session to Rgui I 
feel bad!
