Hi,
I am trying to build a window where to redirect the standard
output. So, I constructed a new class in which I included a TGTextView.
Whenever something is writen to a special output buffer, it forwards the
message to this TGTextView with code like:
void MyTextFrame::AppendText(const char* str){
fTextView->AddLine(str);
//Do I need the following line. It is never clear when it should be
//called
fClient->NeedRedraw(fTextView);
}
The problem is that this does nothing!... The only way to make it work is
having something like:
void MyTextFrame::AppendText(const char* str){
//fText is a TString
fText += str;
fTextView->LoadBuffer(fText);
//Do I need the following line. It is never clear when it should be
//called
fClient->NeedRedraw(fTextView);
}
But this slows down the program when the output is big, and always places
the scroll bar at the begining. I am compiling with:
ROOT Version 2.25/01 9 August 2000
CINT/ROOT C/C++ Interpreter version 5.14.44, Jul 18 2000
Linux RH 6.1
Any ideas on making this work properly. Thank you very much:
Isidro
