Form show is not immediate

amolypalshetkar

fun1(){

Code A
form1.show();
Code B
}

My problem is that until code B is not finished form1 is not shown immediately. Please tell me the solution for this.

Hello amolypaishet..

include<QDialog>
fun1(){
qDebug() << "Code A";

QDialog wid;

wid.exec&#40;&#41;;

qDebug(&#41; << "Code B";

}
Try this.

#include<QDialog>

fun1(){

qDebug() << “Code A”;

w.show(); // Should display wait screen dialog
/* My problem is that wait screen is not shown immediately but shown after code B is executed. */

qDebug() << “Code B”; // Perform some calculations and read write to I/O device.

w.hide(); // Hide wait screen dialog
}

This could be possible
fun1(){

code A;
w.show(); //immediate show
sleep(2000); //sleeps for 2 seconds
code B;
w.hide();
}

Tried the sleep(2000) but still the wait screen wont show up before code B gets executed.

sleep() will make the delay even longer.

In the future, please don't post the same question in different places. You already asked this at http://qt-project.org/forums/viewthread/38913/

Try threading if you want things in parallel.
or try timer .
