How to create multi windows Qt project

martial123

Hi everyone,

My question is :
How we can create project on Qt in order to have different windows show like this example:

//program start by main.cpp

First_window.show() //configuration window for example
do something... 
First_window.close()

Second_window.show() //this is the main window
do something 
Second_window.close()

//program finish

I know this is possible to do that with Hide() and show() but this technique not convince me because 2 process running in the same time and this is not optimize . Imagine we have more windows, this is just not viable..

So exist a good solution to do that ? like a good practice

Thank you

Just a note: there are no two processes at the same time.

You can do it like this: show your first window. When it finished with it's work it can create the second window show it and close itself.

How you do that ?
in main.cpp ?

For instance with signals and slots - emit a signal when the first window is closed and open the second in your slot.

The first window is created in main as usual. The second can be created in the first window as I wrote before.
