Re: [ROOT] Recent changes in rootcint.cxx

Hi Philippe,

   the same problem is observed by ALICE where AliRoot also does not 
compile anymore due to the same kind of errors.

Cheers, Fons.

Re: [ROOT] Recent changes in rootcint.cxx

Hello,
     apparently rootcint now generates code that requires copy  
constructors. As long as they are all "synthesised" things are ok,  
but if you defined one of them as protected or private, then the code  
fails. The solution is to remove all copy constructors, or define and  
implement all the needed ones. A pain in the lower-rear. Best,

[ROOT] program wait for input

Hello,

I have a program that pops up a dialog box that will gather user
input.  I'd like execution to stop until the user has supplied that
input and pressed "OK" on the dialog box.

I thought that gSystem->ProcessEvents() would force that wait, so I
have the present code snippet:

// Pop up a dialog box and get info about the file.

      SimpleDialog();               // pop up the dialog
      gSystem->ProcessEvents();     // should wait for input?
      cout << "File has " << ncols << " columns" << endl;

The output from the cout line shows that the system is not waiting for
input.

Thanks for any help,
Roger

RE: [ROOT] Recent changes in rootcint.cxx

Hi,

Due to a weakness in CINT (privacy level of nested class is hard
to get to), I re-instated the '#define private public' trick which
is still required to properly deal with nested private and protected
classes ...

This will stay as is until CINT has been fully upgraded to use Reflex.

Cheers,
Philippe.

Hi Phillippe,

I made an example for you based on a stripped down version of
the class I reported the problem with and using the $ROOTSYS/test
environment.

Re: [ROOT] program wait for input

Hi Roger,

   after mapping a dialog window, use gClient->WaitFor(dialog) to wait for 
the dialog to pop down. For examples see $ROOTSYS/tutorials/gui/guitest.C.

ProcessEvents() just processes any pending events and then returns.

Cheers, Fons.

[ROOT] RE: canvas print statement

You can do:
gErrorIgnoreLevel = 5000;
(see TError.h)

[ROOT] removal of points from TGraph

Hello,

When I plot data using a TGraph I see that it is possible to remove
points by right-clicking the mouse and selecting the appropriate
option from the pop-up menu.

Does this delete those points from the underlying x,y arrays of the
TGraph, or just from the display?  I need to know if the "removed"
points would be used in a subsequent fit of the data.

If removal does not edit the underlying arrays, then is there a method
by which I _can edit those arrays (preferably some graphical method)?

Thanks for any help,

Roger

RE: [ROOT] Problem with Form() in Windows

Hi Dylan,

I can not reproduce the problem with 5.14/00.

Could you try using that version of ROOT?

Thanks,

Dear Roottalk,

There appears to be a problem with the Form() function in windows.

When I use a format string that includes a "%.4e" followed by a "%s",
the string does not appear in the output.

See the attached script for an example and its output.

Linux does not appear to have any problem.

My system configuration is:

The points are removed from the internal arrays

The fit methods will not use the points that have been removed

RE: [ROOT] removal of points from TGraph


Hi,

The RemovePoint function you access from the pull down menu first find
the closest graph's point to the mouse position and then call
RemovePoint(i) where "i" is the index of the point found. RemovePoint(i)
removes the data point. 

Cheers,  O.Couet
