Hi,
How is it not useful ? The QTimer approach is the right one if you want to display a progressive counter in a way that your application user can see it.
Using a loop like you do just blocks the event loop. That's why you only see the widget content after the loop ended.

@J.Hilk
but this type not usefull on ui(user interface) window, i want to display this data on mainwindow.ui.@Rameshwar If you need this code inside mainwindow then put it there, it isn't that hard.

@jsulm
but if you write code inside mainwindow then , it does not display step by step directly it displays last value that is 999 or using append it displays 0,1,2.....999 once time but i want it displays step by step first it display "1" then increment (i++) then it display "2" then and again it (i++) increment by one and display 3....999. -

Please show your code.

for(j=0;j<1000;j++)
// {
ui->textBrowser->setText(QString::number(j)); //display 0 to 999
// }
//your code here@Rameshwar This code is NOT what @J-Hilk suggested...

@Rameshwar This is exactly what was already suggested (using QTimer). Did you try?!

i want to display contineousaly some data after one second on window.ui
everyone here understood your requirement! Solutions are suggested ! why don't you try instead of repeating the same thing over &over ?

@J-Hilk has given you the necessary code to start from. That's why people type in answers to questions. First try that and verify it works.
-
Then change it so that it writes on your mainwindow or whatever you want instead.
-
Only after that, write back if you can't get what you want working.
