    Hello, In my application i have 2 windows when i ran my Qt widget program it built correctly . In application output for first window there is no the cancel 'X' in the right-upper corner and also no title displayed which i set using setWindowtitle() but it appears in second window. So how to get cancel option for first window too?

      Hi @shree_121,

      can you please show a screenshot of your problem?

      Qt has to stay free or it will die.

              hi
              Just to rule out a broken installation.
              Could you try a default GUI project?

                  @shree_121 Do you run a window manager?

                      hehe. well the windows manager draws the decorations.
                      so no windows manager, no decorations such as frames and close icons etc. :)
