Someone once asked me about the difference between show and showdialog. Here I will give you some advice!
In the face of Multi-Window calls, we often do not like random switching between windows, so we still have to spend time looking for the windows we are using, the window sequence may also be disrupted again, which is very difficult. What should we do?
We can convert the show method to the showdialog method. As the name suggests, showdialog is a show method bound to a path. It cannot be switched freely, that is, if you do not close your current page, you cannot close any page next to the page. It is currently unique (opened by a channel) and is true.
Because the show method is not bound, the displayed windows and dialog boxes can be switched to each other without closing the current window and dialog box. However, the order of the window opened by the show method is not fixed because it is not bound. If there is any problem, the sequence of windows opened by the show method may be greatly changed!
