---|
7 | // |
---|
8 | // Apart from normal Qt command-line arguments, it accepts the following options: |
---|
9 | // -minimized Start minimized, pop up on error |
---|
10 | // -keep Don't close the window at the end |
---|
11 | // -title TITLE Set the window caption |
---|
12 | // |
---|
13 | // If both are -minimized and -keep specified, GUI will only keep the |
---|
14 | // window if it's in focus. |
