I use ROOT 5.6/00 with Windows XP.
I followed the example given in Guitest (ROOTSYS/tutorials/gui/guitest.C) to form my tool bar with two menus File and Help. Under the sub menu File I have Save and Print.
When I click on save, the save window of ROOT opens. what enables me to introduce the name of the file to be saved.
After having clicked on the button save, the window is closed, but the file is not saved.
I beg who can help me to check my code for to see why I can’t save the file on the disc.
This is my code . and in attachement there is the photo of the widget.
