how to show an app if it manually hide

[jthacker]

hi guys,

i have an app.

i have made a function in my main file of the app.

in which i want show and hide app automatically after every 5 sec.

while(1){
        app.show();
        sleep(5);
        app.hide();
        sleep(5);
};

while(1){
        app.show();
        sleep(5);
        app.hide();
        sleep(5);
};

To copy to clipboard, switch view to plain text mode 

but once it is minimized it is not showing anything

what to do?
