Is overlapping layer possible in qt layouts?

[sevketk]

Ok. I tried. I create with qt creator ui designer new Qdialog

and add one button (preffered size policy) , add layout horizantal and I called it

void MainWindow:n_pushButton_clicked()
{
Dialog myDialog;
myDialog.setModal(false);
myDialog.exec();
}

when I run it , mainwindow occupied the entire screen, but qdialog remained to the extent given. this is result

Why don't you explain exactly what it is you want this dialog to do?

You have set the dialog size to 400 x 300 in Qt Designer, so that is what you see when you call exec(). You did not construct myDialog with the MainWindow instance (this) as the parent, so the dialog is centered on the screen, exactly as it is supposed to be when it it created as a top-level widget (ie. with no parent).

And despite your code calling setModal( false ), when you call exec() it cancels this and displays the dialog as modal. If you want a non-modal dialog, you must use show() and hide().

this seems to be the solution for me.

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
, ui(new Ui::MainWindow)
{
ui->setupUi(this);
myDialog = new Dialog(this);
}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow:n_pushButton_clicked()
{

//myDialog.setModal(false);
myDialog->showMaximized();
myDialog->raise();

}
