QPushbutton movable Dynamically
-
ok didnt check it lately , i assume its because the NewSize from event has not yep been applied.
I think i get your use case now
the button show sort of go to next col if there is no room to be below.
So its not on top of the other but on top in new col?
like this

@Apeksha
you can use
const QSize &QResizeEvent::oldSize() const
const QSize &QResizeEvent::size() const
to check what size window has and had.Based on those numbers , you can do the right thing, store button pos
or to restore the button to old pos.you can use qDebug() << "size" << event.oldSize() << " to " << event.Size();
to get an idea of what numbers you will see.
You can use
http://doc.qt.io/qt-5/qdesktopwidget.html#availableGeometryto get how big screen is.

I understood saving of old position and new position, but how to restore i.e hoe to set button old position to restore?

I have used the same, but it's not working.
void MainWindow::resizeEvent(QResizeEvent* event)
{
qDebug() << "old size" << event->oldSize() << " to " << event->size();
int oldx,oldy;
oldpos=ui->pushButton->geometry();
oldx=oldpos.x();
oldy=oldpos.y();
qDebug()<<"oldpos x is"<<oldx<<"oldpos y is:"<<oldy;
if (!firstTime) {
ui->pushButton->move(50,100);
}else { ui->pushButton->move(oldx,oldy); firstTime = false; } QMainWindow::resizeEvent(event);
}

@Apeksha "it's not working" doesn't help to solve the problem.
Did you analyse why it is not working? You can print out the values oldX, oldY for example.void MainWindow::resizeEvent(QResizeEvent* event)
{
qDebug() << "old size" << event->oldSize() << " to " << event->size();
int oldx,oldy;
oldpos=ui->pushButton->geometry();
oldx=oldpos.x();
oldy=oldpos.y();
qDebug()<<"oldpos x is"<<oldx<<"oldpos y is:"<<oldy;
if (!firstTime) {
ui->pushButton->move(50,100);
}else { ui->pushButton->move(oldx,oldy); firstTime = false; } QMainWindow::resizeEvent(event);
}

@Apeksha Your current resizeEvent is wrong: you read CURRENT button geometry and use it as OLD geometry! You need to store the old posx/posy before and restore it later when needed.
K i uderstood , Initially I will save oldx and oldy in constructor and where actually i have to use this oldx and oldy to restore. In above code If I use this oldx and oldy , its not restoring. I am attaching code:
void MainWindow::resizeEvent(QResizeEvent* event)
{
if (!firstTime) {
ui->pushButton->move(50,100);
}else { ui->pushButton->move(oldx,oldy); ---->This oldx and oldy Iam storing in constructor. firstTime = false; } QMainWindow::resizeEvent(event);
}

I think, Problem seems to be with enabling of flag "firsttime".
CAN YOU TRY THIS?
int oldX,oldY,fstFlag=1;
void MainWindow::resizeEvent(QResizeEvent *event)
{
if(!fstFlag)
{
oldX=0;
oldY=0;
fstFlag=1;
}
else
{
fstFlag=0;
oldX=50;
oldY=100;
}
ui->pushbutton->move(oldX,oldY);
} -
