Calling the dialog checkbox from mainwindow

alfah

You have declared Dialog *tt in tha MainWindow.h.

Then in the mainWindow.cpp
jus the following is needed
@
tt = new Dialog(this);
@
right???

is the following line needed in the dialog.h??
@
Ui::MainWindow *uu;
@

kalster

i am getting an error in the mainwindow error: 'class Dialog' has no member named 'checkBox'. the tt = new Dialog(this); line is for dialog methods. i need it for dialog widgets in the mainwindow.cpp file.

alfah

Im not an expert :)

u have a checkbox in your dialog.h. and it is made in the designer??

You want to jus show that check box in the mainWindow??

Am i right???

kalster

yes. i want to call the dialog checkbox from mainwindow

alfah

This displays the check box.
The following is written in the constructor of MainWindow.cpp

@
ui->setupUi(this);
Dialog *d= new Dialog();
d->show();
setCentralWidget(d);
@

not working. please verify.

alfah

it is working on my device. Remember i have called the dialog class/form from the mainwindow ,if thats wat you want

Dialog.cpp

@

Dialog::Dialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog)
{
ui->setupUi(this);
setLayout(ui->verticalLayout);

}
@

MainWindow.cpp
@
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
Dialog *d= new Dialog();
d->show();
setCentralWidget(d);

}
@

kalster

o yes. it worked.

alfah

:) ok, [Solved] i guess

kalster

not yet. the setCentralWidget(tt); hides the widgets on my mainwindow

alfah

ofcourse it will!! because what you have done is callin a form from the MainWindow, so it will be shown over the MainWindow. You din tell me you had widgets on the MainWindow!

kalster

is there another way around this?

alfah

would you explain a bit on what is there on the mainWindow and what exactly you want to do ?How do you want to display??

I have a lot of widgets on the mainwindow. when the program loads, it loads the mainwindow and then the dialog. the dialog loaded is not in focus so i need to load the dialog from the mainwindow and then check if the dialog is loaded. if the dialog is not loaded then i need to write some code in the mainwindow.

i need to call the dialog checkbox from the mainwindow to determine if the dialog is displayed. if the dialog is not displayed then i can write my code in the dialog.cpp file.

alfah

loaded as in displayed?

kalster

yes that's correct
