[SOLVED] how to link a form(.ui) to another form using push button

[Guest]

Hi,
mainwindow.h
@#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include "mainwindow1.h" //adding second window
namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
MainWindow1 *objmain1; // creating object for the second window
~MainWindow();
private slots:
void btnaction(); // creating slots
private:
Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H@

mainwindow.cpp

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

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(btnaction())); // creating connections
}

void MainWindow::btnaction()
{
objmain1 = new MainWindow1;
objmain1->show(); //opening second form
}
MainWindow::~MainWindow()
{
delete ui;
}
@

this will open the new window seperately. if you want to open the new window inside the first window means you have go for the parent child concept

Hi,
i am searching the sample mdi parent chid project in my pc wait for while

[Guest]

you can use QWorkspace for that

[Guest]

Hi,
here i have used menubar instead of QPushbutton so u try to understand the concept and do it in your own way.....
mdiwindow.cpp

@#include "mdiwindow.h"
#include "ui_mdiwindow.h"
#include <QMessageBox>
#include <QVariant>
#include <QString>
MDIWindow::MDIWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MDIWindow)
{ ui->setupUi(this);
workspace = new QWorkspace;
setCentralWidget(workspace);

connect(ui->actionChild1,SIGNAL(triggered()),this,SLOT(OpenChild1()));
connect(ui->actionChild2,SIGNAL(triggered()),this,SLOT(OpenChild2()));
//connect(&cw1,SIGNAL(ChildWindow1Closed()),this,SLOT(StatusUpdate()));

connect(ui->actionChild_window_status,SIGNAL(triggered()),SLOT(ChildStatus()));
connect(ui->actionActivated_Window,SIGNAL(triggered()),SLOT(FindActivatedWindow()));
connect(ui->actionChild_Window_Count,SIGNAL(triggered()),SLOT(FindChildCount()));

}

MDIWindow::~MDIWindow()
{
delete ui;
}
void MDIWindow::FindChildCount()
{
//Type Conversion from int to string
int a =workspace->windowList().count();
QString str;
str=QVariant(a).toString();
str=QString::number(a,16);
statusBar()->showMessage("Child Window Count is" + str );
}
void MDIWindow::StatusUpdate()
{

}
void MDIWindow::FindActivatedWindow()
{
if(!workspace->windowList().isEmpty())
statusBar()->showMessage(workspace->activeWindow()->windowTitle() + " is Activated Now " );
else
statusBar()->showMessage("No Active Child Window");
}
void MDIWindow::ChildStatus()
{
if(workspace->windowList().isEmpty())
{
statusBar()->showMessage(" No Child Window Opened");
}
else
{
statusBar()->showMessage("Child Window Opened");
}
}
void MDIWindow::OpenChild1()
{
if(!ObjChild1->isVisible())
{
ObjChild1 = new ChildWindow1;
}
workspace->addWindow(ObjChild1);
ObjChild1->setWindowTitle("Child1");
ObjChild1->show();
statusBar()->showMessage(workspace->activeWindow()->windowTitle() + " Opened Just Now");
}
void MDIWindow::OpenChild2()
{
if(!ObjChild2->isVisible())
{
ObjChild2 = new ChildWindow2;
}
workspace->addWindow(ObjChild2);
ObjChild2->setWindowTitle("Child2");
ObjChild2->show();
//statusBar()->showMessage("Child Window opened");
statusBar()->showMessage(workspace->activeWindow()->windowTitle() + " Opened Just Now");
}
@

mdiwindow.h

@#ifndef MDIWINDOW_H
#define MDIWINDOW_H

#include <QMainWindow>
#include "childwindow1.h"
#include "childwindow2.h"
#include <QWorkspace>

namespace Ui {

}

class MDIWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MDIWindow(QWidget *parent = 0);
~MDIWindow();

//ChildWindow1 cw1;
private slots:
void OpenChild1();
void OpenChild2();
void ChildStatus();
void FindActivatedWindow();
void FindChildCount();
public slots:
void StatusUpdate();

private:
Ui::MDIWindow ui;
QWorkspace workspace;
ChildWindow1 ObjChild1;
ChildWindow2 ObjChild2;
};

#endif // MDIWINDOW_H

[quote author="cdeepak" date="1329371126"]you can use QWorkspace for that
[/quote]

QWorkspace is deprecated!

Please use [[Doc:QMdiArea]] and [[Doc:QMdiSubWindow]].
